system controller
The entire data transmission between various components of the system controller processing module:
Security related processor system
System bus A and B
Ethernet switch with connection interface
memory
This module has RAM and non-volatile memory. Non volatile memory is protected by CRC.
Non volatile memory contains the following programs and information:
operating system
User project
Enable switch, watchdog time, safety time
Online modification
Variables with RETAIN attribute
Production data, if necessary, trim data
Fault status history
event
At startup, the system transfers program code from non-volatile memory to redundant program and data storage.
Alarm and Events
The processor module records alarms and other events in its non-volatile memory.
An event is a change in the state of a variable executed by a factory or controller, with a timestamp provided.
An alert is an event that indicates an increase in potential risk.
The HIMax system records state changes as events at a specified point in time. The X-OPC server transfers events to other systems that display or evaluate events, such as control systems.
HIMax distinguishes between Boolean events and scalar events.
Boer Event:
The variation of Boolean variables, such as the variation of numerical inputs.
Alarm and normal states: They can be arbitrarily assigned to variable states.
Scalar event:
Exceeding the limit value defined for scalar variables.
Scalar variables have numerical data types, such as INT and REAL.
Two upper limits and two lower limits are possible.
For the limit value, the following conditions must be met:
Maximum limit ≥ upper limit ≥ normal area ≥ lower limit ≥ minimum limit.
Lag may be effective in the following situations: – if the value is below the upper limit. If the value exceeds the lower limit.
Lag is defined as avoiding unnecessary large events when the global variable oscillates strongly near the limit.
Create Event
Both processor modules and certain types of I/O modules are capable of creating events. at
In the following sections, these I/O modules are referred to as SOE modules.
Create events on the processor module
The processor module creates events using global variables and stores them in a buffer, please refer to Chapter 3.4.7. The event is created during the user program cycle.
Create events on the SOE module
The SOE module can create events using input states. The event is created within the SOE module loop.
The SOE module stores events in the intermediate buffer used by the processor module to read them. The intermediate buffer is a part of volatile memory, so if the power is turned off, events will be lost.
Every event that has been read can be overwritten by a new event.
system event
In addition to recording events related to changes in global variables or input signals, the processor and SOE module also create the following types of system events:
Overflow: Due to buffer overflow, some events were not stored. The timestamp of the overflow event corresponds to the timestamp of the event that caused the overflow.
Initialization: The event buffer has been initialized.
Operation mode stop: SOE module changes its operation mode to stop.
Operation mode ‘Run’: The SOE module changes its operation mode to ‘Run’.
Establish communication: Communication between the processor module and SOE module has begun.
Lost Communication: Communication between Processor Module and SOE Module
Terminated.
The system event contains the SRS identifier of the module that caused the event.
state variable
State variables provide the state of scalar events for user programs. Each of the following states is connected to a state variable that can be assigned a BOOL type global variable:
Normal.
Exceeding the lower limit.
The minimum limit has been exceeded.
Exceeding the upper limit.
The maximum limit has been exceeded.
When the corresponding state is reached, the assigned state variable becomes TRUE.
Recording events
Processor module collects events:
Created by I/O module
Created by the processor module itself
The processor module stores all events in its buffer. A buffer is a part of non-volatile memory with a capacity of 5000 events.
The processor module arranges events from different sources based on their arrival time, rather than sorting them by timestamp.
If the event buffer is full, as long as no other events are read and marked as overwritten, new events cannot be stored.
OPC servers can read events and provide them to external systems for evaluation and storage.
Mode Switch
The mode switch defines the behavior of the processor module when it restarts.
The processor module will restart in the following situations:
Automatic: – When connected to working voltage – After severe malfunction – After loading the operating system
During the operation, use the corresponding commands on PADT.
The mode switch has three different switch positions:
initialization
stop
run
The switch position during normal operation is in operation.
Switch position: initialization
The Init switch position is used to set the processor module to LOCKED state. In this state, the settings previously configured for the module cannot be accessed anymore. For example, if the administrator password is unknown, this operation may need to be performed.
In the locked state, the module is reset to factory settings:
Default SRS, slot number depends on the slot used
Default IP address and IP settings
Only administrator user accounts with empty passwords can access
Enable the switch set to default value
The modified settings in this state will overwrite the factory settings and all previously used settings!
If the settings remain unchanged, the previously saved settings (switch not set to Init) will be used when restarting the module.
start
To start the processor module, insert it into the allowed motherboard slot. If the substrate is already running, the processor module will start and adopt the operating state set through its configuration and mode switch position. If the substrate is not working, please connect the power supply voltage.
install
When installing the processor module, please pay attention to the following points:
This module is designed for use with HIMax substrates. For more information about the bottom plate structure, please refer to the corresponding system documentation.
Operate the processor module only in the expected slot
Only the forced cooling (X-FAN) operation module can be used.
Only use appropriate connector boards to operate the module.
The effect of removing and inserting modules:
When disassembling the module, the connector board remains in the HIMax substrate.
Since all external interfaces are connected through the module’s connector board, the module can be replaced without affecting the external interfaces
The SRS of the module is stored on the connector board and becomes SRS after the module is inserted.
The effect of removing the plug
Pulling out the plug will interrupt external communication.
Take appropriate grounding measures.
User Program
The application program functions that PES should execute are specified in the user program. PADT is used to create and compile project configurations using user programs, and load them into processor modules.
Start processor module
The processor module can be started as follows:
Insert it into the substrate that provides working voltage
Open the working voltage of the substrate for inserting the module.
The behavior at module startup depends on:
Position of mode switch
There are additional redundant processor modules present
There are valid project configurations (including user programs) in non-volatile memory
When the switch is set to stop or run, the processor module will check if there are any other processor modules present
If there are no other processor modules, the module will start running separately.
If there is at least one additional processor module, the module attempts to automatically start operating using the configuration of the existing processor module. Maintain a safety rope.

Common troubleshooting
Possible causes and solutions for the fault phenomenon
Unable to start battery depletion (some models), insufficient/deteriorated fuel, incorrect throttle position, spark plug failure, low fuel protection triggering refueling or replacement with fresh fuel; Adjust the position of the air door; Clean or replace spark plugs; Add engine oil
Insufficient pressure/no pressure inlet flow, nozzle blockage, inlet filter blockage, high-pressure hose leakage, pump body failure increase water source flow; Clean the nozzle and inlet filter screen; Replace damaged hoses; Check the sealing components of the pump body
Unstable engine operation, clogged air filter, poor fuel supply, and air damper not adjusted to the “RUN” position. Clean or replace the air filter; Check if the fuel pipeline is blocked; Adjust the air damper to a stable operating state
The soap cannot be suctioned out, the siphon hose is blocked, the black nozzle is not used, and the soap tank level is too low. Clean the siphon hose; Replace the black nozzle; Supplement soap solution
Avoid running the pump without load for more than 5 minutes due to overheating, insufficient water intake, and malfunction of the heat release valve; Check if the water inlet is unobstructed; Contact after-sales service for maintenance of the heat release valve
Power performance: Continuous power 6000W, peak power 7500W, voltage 120/240V single-phase, frequency 60Hz. Peak power is only used to start inductive loads (such as motor equipment), and continuous operation requires ≤ 6000W
The engine system is a four stroke single cylinder OHV engine with a cylinder diameter of 66 × 90mm and an ignition method of TCI (transistor ignition). The OHV design improves combustion efficiency and extends engine life; Forced air cooling for heat dissipation, suitable for long-term operation
Oil specifications: Oil capacity 1.1 liters, recommended models: SAE 10W-30 (normal temperature -10~40 ℃), 5W-30 (low temperature<-10 ℃), SAE 30 (high temperature>30 ℃). API SJ or higher grade four stroke engine oil is required, and the use of two-stroke engine oil or mixed engine oil is strictly prohibited
The fuel tank capacity of the fuel system is 25 liters (6.6 gallons), suitable for unleaded gasoline of grade 87 and above. E15/E85 ethanol gasoline is prohibited if the ethanol content is ≤ 10% (which can easily cause corrosion and blockage of the fuel system); 50% load can run for more than 10 hours under full oil condition
Starting method: Electric start (12V lead-acid battery), manual manual start (emergency backup). Electric start requires sufficient battery power, and manual start is an emergency plan suitable for battery depletion scenarios

Fuel system: large capacity fuel tank (with fuel gauge), fuel shut-off valve (controlling fuel supply on/off), fuel filter (sedimentation cup type, filtering impurities), carburetor (atomizing fuel).
Power generation system: AC generator (with AVR voltage regulator, stable output), equipped with main circuit breaker and branch circuit breaker to prevent overload and short circuit.
Mobile and Fixed Components: Universal Wheels (Wear resistant and Anti slip), Telescopic Handle (Rubber Anti slip Grip), Bottom Support Feet (Enhance Placement Stability), Shock Absorbers (Reduce Operating Vibration).
(2) Control panel full analysis
Component Name Function Description Operation Points
The electric start switch (START/RUN/STOP) integrates the functions of starting, running, and stopping. Press “START” for 1 second to start, keep “RUN” for running, and set “STOP” for stopping
The hour meter records the cumulative operating time of the generator to remind maintenance intervals (such as 50 hours of oil change), and only counts under load conditions
Two 120V 20A GFCI dual socket outlets output 120V AC power with leakage protection. The maximum load of a single socket is 2400W, and the total load of the dual sockets is ≤ 4800W. After use, close the waterproof cover plate
120/240V 30A locking socket (1) outputs mixed voltage, suitable for high-power equipment (such as air conditioning, water pump) with a maximum load of 7200W (240V) or 3600W (120V), requiring the use of a dedicated L14-30R locking plug
Circuit breaker (20A/25A) 20A corresponds to a 120V socket, 25A corresponds to a 240V socket, and automatically trips when overloaded/short circuited. Before resetting, the fault needs to be investigated (such as reducing the load and repairing the short circuit)
The grounding terminal is used for external grounding (such as when connected to a household power distribution system). The neutral wire is already connected to the body and does not require additional grounding when used separately; Grid connection must be grounded according to regulations
The fuel gauge visually displays the remaining fuel level in the fuel tank. When the fuel level is less than 1/4, it should be replenished in a timely manner to avoid running out of fuel and shutting down during operation
Only use in fully open and well ventilated outdoor areas, at least 6 feet (about 1.8 meters) away from doors, windows, ventilation openings, tents, etc., to prevent carbon monoxide exhaust from entering indoors (the engine exhaust contains highly toxic carbon monoxide, which is colorless and odorless).
Place on a hard, horizontal surface (with an inclination angle of ≤ 5 °) to avoid engine wear caused by fuel leakage or uneven oil lubrication; Do not place it on loose surfaces such as sand or grass (which can easily attract debris and block the heat dissipation outlet).
At least 3 feet (about 0.9 meters) of heat dissipation space should be reserved around the fuselage, away from flammable materials such as hay, wood, paint, gasoline, etc. The muffler should face the unmanned area (the temperature can reach 400 ℃ or above during operation).
Environmental limitations and responses:
Prohibited scenarios: rainy, snowy, or damp ground (to prevent electric shock); Closed/semi closed spaces (such as garages, basements, tents); Dust and corrosive gases (such as coastal salt spray and chemical plant areas) environment.
Extreme weather: In rainstorm days, temporary awning (not sealed, ensure ventilation) shall be built to prevent rain from splashing the engine and control panel; In high temperature weather (>35 ℃), it is necessary to reduce the capacity for use (reduce the capacity by 10% for every 10 ℃ increase).
2. Fuel safety operation
Preparation before refueling:
Turn off the engine and wait for at least 5 minutes for it to cool down (due to the high temperature of the muffler and engine block, which can easily ignite the fuel).
Clean the oil and dust around the fuel tank cap to prevent impurities from entering the fuel tank; Prepare a qualified fuel can and do not pour it directly from a bucket.
Refueling operation specifications:
Slowly add fuel, with the fuel level not exceeding the lower edge of the fuel tank filling port (leaving 5-10% expansion space), to avoid fuel spillage during high temperatures.
If fuel overflows, immediately wipe it clean with a dry cloth and wait for the fuel to completely evaporate before starting the engine (do not ignite immediately); Check for leaks at the connections of the fuel tank and oil pipes. If there are leaks, do not start.
Fuel storage and handling:
Backup fuel should be stored in a compliant fuel container, in a well ventilated, cool, and away from sources of ignition. The storage time should not exceed 3 months (with the addition of fuel stabilizers, it can be extended to 6 months).
Degraded fuel must be handed over to professional institutions for recycling, and it is prohibited to dump it indiscriminately (which pollutes the environment and is flammable).
Forbidden operation: Do not refuel while the engine is running; Do not use fuel to clean the body or components; Do not place fuel containers on the generator or near heat sources.
3. Electricity safety regulations
Extension cable selection:
Outdoor dedicated, undamaged, and well grounded three core cables must be used, with cable specifications matching the load and length:
20A load (such as small power tools): use 14 gauge cable for lengths ≤ 25 feet; Use 12 gauge cable for ≤ 50 feet.
30A load (such as 3kW air conditioner): use 10 gauge cable for lengths ≤ 50 feet; Use size 8 gauge cable for ≤ 100 feet.
It is prohibited to use two core ungrounded cables, damaged cables, or multiple cables connected in series (which are prone to heating and leakage).
Load access principle:
Before starting, all loads must be disconnected to avoid overload triggering protection during startup (the starting current is 3-5 times the operating current).
After the generator runs stably (no-load for 3-5 minutes), connect high-power devices (such as air conditioning and water pumps) first, and then connect low-power devices (such as lights and mobile phone chargers), with a total operating power of ≤ 6000W.
Inductive loads (motor type) require separate calculation of starting power to avoid multiple units starting simultaneously (such as a 3kW air conditioner+a 2kW water pump, the starting power may exceed 7500W).
Grounding and grid connection requirements:
The neutral wire of the generator is connected to the metal casing of the machine body, and does not require additional grounding when used alone; If it is necessary to connect to the household fixed power distribution system, a certified electrician must install an automatic transfer switch (direct grid connection is prohibited to avoid reverse power transmission to the grid).
When connecting metal shell equipment (such as power tools, water pumps), ensure that the equipment is well grounded to avoid electric leakage and shock.
GFCI socket usage:
Before each use, it is necessary to test: after starting the generator, press the “TEST” button on the socket, and the socket should trip and cut off power; Press the “RESET” button again to reset and confirm that the power supply is normal.
If GFCI trips frequently, it may be due to equipment leakage or cable damage, and the fault needs to be investigated before use.
4. Personnel safety protection
Operation protection: goggles must be worn (to prevent fuel splashing and debris from entering the eyes), gloves must be worn (to prevent oil contamination and burns); Long hair should be curled up to avoid getting caught up in moving parts such as starting ropes and fans.
Personnel management: Children and pets should stay away from the running generator (at least 3 meters away); Do not operate the generator when fatigued, under the influence of alcohol, or after taking medication (which affects judgment).
Emergency response:
If symptoms such as dizziness, nausea, and fatigue occur after inhaling carbon monoxide, immediately transfer to fresh air and seek medical attention in severe cases.
If burns occur (due to contact with high-temperature components such as mufflers), immediately rinse the burned area with cold water, and seek medical attention in severe cases.
If a fire occurs, use ABE or BE type fire extinguishers to extinguish it (it is prohibited to directly extinguish electrical or fuel fires with water).
Complete operation process (assembly → start → run → stop)
1. First use assembly and preparation
Open box inspection:
Remove the generator and its accessories (wheel kit, feet, tool kit, oil, battery, manual, quick guide).
Check that the appearance of the generator is undamaged, the components are not loose, the sockets and switches are functioning properly, and the battery is fully charged (voltage ≥ 12V).
Install wheels and feet:
Tilt the generator (ensuring that the fuel shut-off valve is closed to avoid fuel leakage), and use the attached M8 flange bolts to secure the support feet on both sides of the bottom of the fuselage.
Thread the wheel axle pin through the wheel and body bracket, insert the washer, insert the split pin and bend it to lock, ensuring that the wheel rotates flexibly and is securely installed (which can drive the generator to test stability).
Install battery:
Find the battery compartment on the body, first connect the red positive cable to the positive pole (+) of the battery, and put on an insulating sheath; Connect the black negative cable to the negative pole of the battery (-), and also cover it with a protective sheath (to avoid short circuits between the positive and negative poles).
Confirm that the cable connection is secure, fix the battery in the battery compartment, and avoid shaking during operation.
Add engine oil:
Place the generator on a level surface, unscrew the oil filler cap on the side of the body, and take out the dipstick.
Slowly add the recommended model of engine oil (SAE 10W-30) and check the dipstick while adding until the oil level is between the “L” (lowest) and “H” (highest) marks (not exceeding the “H” mark to avoid excessive oil accumulation and oil leakage).
Tighten the oil filler cap and dipstick, and wipe off any remaining oil with a dry cloth.
Add fuel:
Unscrew the fuel tank cap (counterclockwise) and clean the impurities around the fuel inlet.
Add unleaded gasoline of grade 87 or above, with the fuel level not exceeding the lower edge of the filling port, and tighten the fuel tank cap (clockwise).
Check for leaks at the connection between the fuel tank and oil pipe. If there is any overflow, wipe it clean immediately.
2. Start the process
Preprocessing:
Confirm that the generator is placed horizontally, the fuel shut-off valve is turned to the “ON” position, all loads have been disconnected, and the circuit breaker is in the reset state.
Cold engine start: Set the air door to the “ON” position (close the air door to increase fuel concentration); Hot engine start: Keep the air door in the “OFF” position (open the air door).
Startup mode selection:
Electric start: Press and hold the “START” button on the control panel for 1 second, and release it immediately after the engine starts (to avoid damaging the starter motor); If it fails to start once, try again after a 15 second interval (up to 3 times, if unsuccessful, switch to manual start).
Manual start: Turn the start switch to the “RUN” position, slowly pull the start rope until there is resistance (piston compression stroke), and then quickly and forcefully pull the handle; After starting the engine, slowly release the starting rope.
Stable operation:
After starting, let the generator run without load for 3-5 minutes, and gradually turn the air damper to the “OFF” position (adjust according to the engine operating status to avoid unstable idle).
Observing the control panel: The hour meter is counting normally, the fuel gauge shows sufficient, the circuit breaker is not tripped, and there is no abnormal noise (such as knocking or whistling).
Load connection:
According to the principle of “high power first, low power later”, connect the devices one by one, ensuring that the plug is fully inserted to avoid loosening and heating.
If connecting to a 240V device, a dedicated L14-30R locking plug is required. After insertion, rotate it clockwise 1/4 turn to lock it; If 120V devices are used simultaneously, the load should be balanced through socket color identification (red/green identification for each device with the same power) to avoid abnormal generator vibration.
3. Monitoring and regulation during operation
Real time monitoring points:
Power monitoring: Total operating power ≤ 6000W, avoid long-term full load operation (recommended ≤ 80% load to extend engine life).
Oil monitoring: Check the oil level every 8 hours, and replenish if it is below the “L” mark; Add fuel promptly when the fuel level is below 1/4.
Temperature monitoring: There are no abnormal hot hands on the side of the body during operation, and there are no foreign objects blocking the heat dissipation port. If the engine overheats, it will automatically shut down. After cooling, clean the heat dissipation fins and restart.
Adjustment operation:
If the circuit breaker trips due to excessive load, immediately disconnect part of the load, press the circuit breaker reset button, and then reconnect.
If the engine speed fluctuates during operation, it may be due to insufficient fuel supply or clogged air filter. Check if the fuel shut-off valve is fully open and if the air filter is clean.
Long term operation (exceeding 2 hours) requires regular inspection of the equipment’s operating status to avoid overheating and cable overheating.
4. Shutdown process (operating in different scenarios)
(1) Normal shutdown
Disconnect all loads (unplug or turn off the device switch).
Run the generator without load for 3-5 minutes to cool down the engine and generator (to avoid direct shutdown due to high temperatures causing carbon buildup).
Turn the start switch to the “STOP” position to shut down the engine; Close the fuel shut-off valve (set to “OFF”).
Close all waterproof covers of sockets and cover with dust covers (if not used for a short period of time).
Directly turn the start switch to the “STOP” position and force the machine to stop (without disconnecting the load).
Follow up processing: Investigate the cause of the malfunction (such as fuel leakage, engine noise), eliminate the fault before use, and prohibit restarting without troubleshooting.
(3) Long term shutdown (exceeding 1 month)
Disconnect the load according to the normal shutdown process and run it without load for 1 minute.
Close the fuel shut-off valve and allow the engine to continue running until the fuel runs out and automatically shuts down (to avoid fuel deterioration and blockage in the carburetor).
Disconnect the battery connection (first unplug the negative cable, then unplug the positive cable), fully charge the battery, and store it separately (to avoid damage due to low battery).
Clean the dust and oil stains on the surface of the generator, check the condition of the air filter and spark plug, and clean them if necessary.
Inject 1 teaspoon of new engine oil into the cylinder and pull the starting rope 3-5 times (without ignition) to evenly distribute the oil on the cylinder wall (rust prevention).
Cover with a dust cover and store in a dry, ventilated, and cool room (do not store in flammable areas).
Complete maintenance process (including cycle and details)
1. Preparation before maintenance
Safety measures: Turn off the generator, disconnect the battery connection, and allow the engine to cool to room temperature (to avoid high-temperature burns); Operate in a well ventilated area and prepare tools (wrench, oil pan, funnel, wire brush, etc.).
2. Routine maintenance items (executed on a periodic basis)
Before/after each use
Cleaning: Use a dry cloth to wipe the dust and oil stains on the surface of the machine body, clean the debris on the heat sink and ventilation openings (to avoid blockage that affects heat dissipation); Check if the waterproof cover of the socket is intact.

Oil level: The engine oil level is between “L” and “H”, the fuel gauge shows sufficient, and there is no leakage.
Battery: The connection is firm, without bulging or leakage (lead-acid batteries need to check the electrolyte level, and if it is insufficient, add distilled water).
Cable and plug: No damage or aging, and the plug has good contact.
GFCI test: After starting the generator, test the leakage protection function of the socket (press the “TEST” button to trip and the “RESET” button to reset).
Run every 8 hours (or after each use)
Oil level check: Add oil to the standard level (not exceeding the “H” mark).
Fuel filter inspection: Observe whether there is moisture or impurities in the sedimentation cup. If there are, unscrew the drain screw to drain it, and then tighten it again.
3. Long term storage and maintenance (over 3 months)
Preparation before storage:
Cleaning: Thoroughly wipe off dust and oil stains on the surface of the body, clean up debris from the heat sink and ventilation vents.
Fuel treatment:
Method 1 (Adding Stabilizer): Fill up with fresh fuel, add fuel stabilizer (according to the instructions), start the engine and run for 5 minutes, let the stabilizer circulate to the fuel system, and close the fuel shut-off valve and battery switch.
Method 2 (Drain Fuel): Close the fuel shut-off valve, unscrew the carburetor float drain screw, and drain the fuel; Unscrew the fuel tank drain screw, drain the fuel from the tank, and then tighten all screws.
Oil change: Change the engine oil according to the procedure (to avoid impurities in the old oil corroding the engine).
Cylinder rust prevention: Remove the spark plug, inject 1 teaspoon of new engine oil into the cylinder, pull the starting rope 3-5 times (without ignition) to evenly distribute the engine oil on the cylinder wall, then reinstall the spark plug and pull the starting rope until the piston is in compression stroke (valve closed to prevent moisture from entering).
Battery handling: Disconnect the battery, store it separately after fully charging, and recharge it every 1-2 months (to avoid battery depletion).
After storage, remove and use:
Remove the dust cover and check the appearance of the generator for any damage or debris.
Connect the battery and check the oil level (replenish if insufficient).
Add fresh fuel (do not use fuel that has been stored for too long).
According to the normal start-up process, the engine may emit smoke for a short period of time (residual oil in the cylinder), which is a normal phenomenon and will disappear after running for 1 minute.
4. Maintain taboos and precautions
Do not use flammable solvents such as fuel or banana oil to clean components (such as air filters and machine bodies) to avoid causing fires.
It is prohibited to mix different brands and models of engine oil, and it is forbidden to use two-stroke engine oil or inferior engine oil (which can damage the engine).
When replacing spark plugs, the recommended model must be used and the tightening torque should not be too high (to avoid damaging the cylinder head threads).
When cleaning the air filter, do not twist or tear the foam filter element, and do not wash the paper primary filter with water (only air blowing).
After all maintenance operations, it is necessary to ensure that the components are securely installed and the screws are tightened to avoid detachment during operation.

START/STOP button for electric start/stop control. Press the start button for 2 seconds and the stop button for 1 second; Press and hold the emergency stop button for 3 seconds
The battery switch controls the opening of the battery power supply circuit before starting, and closes it after stopping (it needs to be disconnected for long-term storage)
The fuel valve switch controls the fuel supply to open (ON) before starting and close (OFF) after stopping. It should be kept closed for long-term storage
Adjust the air intake volume with the throttle knob (only used when manually pulled to start). Close (push in) when starting the cold engine, and open (pull out) when the hot engine or stable operation is achieved
After the GFCI reset button leakage protection trips, it is necessary to investigate the cause of the leakage before resetting to ensure that the equipment has no faults
When the main circuit breaker is overloaded, it will automatically trip. After cutting off the main power supply and tripping, the load needs to be reduced. Press the circuit breaker to reset
The CO alarm indicator light (red) lights up when the CO concentration exceeds the standard. At the same time, the generator needs to be stopped and moved to a ventilated area. After checking the environment, it can be restarted
Only use in fully open and well ventilated outdoor areas, at least 20 feet (about 6 meters) away from doors, windows, ventilation openings, tents, etc., to prevent carbon monoxide emissions from entering indoors.
Place on a hard, horizontal surface, avoiding tilting (angle ≤ 5 °), to prevent fuel leakage or uneven oil lubrication from causing engine wear.
At least 5 feet (about 1.5 meters) of heat dissipation space should be reserved around the fuselage, away from flammable materials such as hay, wood, paint, gasoline, etc. The exhaust port should face unmanned areas.
Environmental limitations and responses:
Operating temperature range: 5 ° F (-15 ° C) to 122 ° F (50 ° C). If it is below -15 ° C, it is necessary to replace the winter specific oil (5W-30) and keep the battery warm (to avoid power loss).
Prohibited scenarios: rainy, snowy, or damp ground (to prevent electric shock); Dust and corrosive gases (such as salt spray at the seaside and chemical plant areas) can easily cause component corrosion and blockage.
Extreme weather: In rainstorm days, a temporary canopy (not sealed, ensure ventilation) shall be built to avoid rain splashing the engine and control panel.
2. Fuel safety operation
Preparation before refueling:
Turn off the engine and wait for at least 2 minutes for it to cool down (the exhaust pipe temperature can reach over 400 ℃, which can easily ignite the fuel).
Clean the oil and dust around the fuel tank cap to prevent impurities from entering the fuel tank; Prepare a qualified fuel can and do not pour it directly from a bucket.
Refueling operation specifications:
Slowly add fuel, with the fuel level not exceeding the red limit ring inside the fuel tank (with 5-10% expansion space reserved), to avoid fuel spillage during high temperatures.
If fuel overflows, immediately wipe it clean with a dry cloth and wait for the fuel to completely evaporate before starting the engine (do not ignite immediately).
Fuel storage and handling:
Backup fuel should be stored in a compliant fuel container, in a well ventilated, cool, and away from sources of ignition. The storage time should not exceed 3 months (with the addition of fuel stabilizers, it can be extended to 6 months).
Degraded fuel must be handed over to professional institutions for recycling, and it is prohibited to dump it indiscriminately (which pollutes the environment and is flammable).
Forbidden operation: Do not refuel while the engine is running; Do not use fuel to clean the body or components; Do not place fuel containers on the generator or near heat sources.
3. Electricity safety regulations
Extension cable selection:
Outdoor dedicated, undamaged, and well grounded three core cables must be used, and the cable specifications must match the load:
20A load (such as small electric tools): Use a 12 gauge cable with a length ≤ 50 feet; 14 gauge cable, length ≤ 25 feet.
30A load (such as 3kW air conditioner): Use 10 gauge cable with a length ≤ 50 feet; Number 8 gauge cable, length ≤ 100 feet.
50A load (if multiple devices are powered simultaneously): Use gauge 6 cable with a length ≤ 50 feet.
It is prohibited to use two core ungrounded cables, damaged cables, or multiple cables connected in series (which are prone to heating and leakage).
Load access principle:
Before starting, all loads must be disconnected to avoid overload triggering protection during startup.
After the generator runs stably (no-load for 3-5 minutes), connect high-power devices (such as air conditioning and water pumps) first, and then connect low-power devices (such as lights and mobile phone chargers), with a total operating power of ≤ 9500W and a total starting power of ≤ 12500W.
The starting power of inductive loads (motors) is 3-5 times the operating power and needs to be calculated separately to avoid multiple inductive loads starting simultaneously (such as a 3kW air conditioner and a 2kW water pump, the starting power may exceed 12500W).
Grounding and grid connection requirements:
The neutral wire of the generator is connected to the metal casing of the machine body and does not require additional grounding; If it is necessary to connect to the household fixed power distribution system, a certified electrician must install an automatic transfer switch (direct grid connection is prohibited to avoid reverse power transmission to the grid).
When connecting metal shell equipment (such as power tools, water pumps), ensure that the equipment is well grounded to avoid electric leakage and shock.
Emergency handling of faults: If equipment trips, heats up, or emits odors during power consumption, immediately disconnect the load, shut down the generator, and troubleshoot (such as overload or short circuit) before use; If there is electric leakage or shock, immediately cut off the power supply and seek medical attention in severe cases.
4. Personnel safety protection
Operation protection: goggles must be worn (to prevent fuel splashing and debris from entering the eyes), gloves must be worn (to prevent oil contamination and burns); Long hair should be curled up to avoid getting caught up in moving parts.
Personnel management: Children and pets should stay away from the running generator (at least 5 feet away); Do not operate the generator when fatigued, under the influence of alcohol, or after taking medication (which affects judgment).
Emergency response:
If you experience symptoms such as dizziness, nausea, and fatigue after inhaling carbon monoxide, immediately move to fresh air and seek medical attention in severe cases (carbon monoxide is colorless and odorless, so be alert).
If burns occur (due to contact with high-temperature components such as exhaust pipes), immediately rinse the burned area with cold water, and seek medical attention in severe cases.
If a fire occurs, use ABE or BE type fire extinguishers to extinguish it (it is prohibited to directly extinguish electrical or fuel fires with water).
Complete operation process (assembly → start → run → stop)
1. First use assembly and preparation
Open box inspection:
Remove the generator and its accessories (tripod, roller, tool kit, engine oil, battery, remote control, manual).
Check that the appearance of the generator is undamaged, the components are not loose, the sockets and switches are functioning properly, and the battery is fully charged.
Install the tripod and roller:
Tilt the generator (ensuring that the fuel valve is closed to avoid fuel leakage), and use the accompanying bolts and wrenches to secure the tripod on both sides of the bottom of the body.
Install the roller into the slot below the tripod, tighten the fixing bolts to ensure that the roller rotates flexibly and is securely installed (which can drive the generator to test stability).
Add engine oil:
Place the generator on a level surface, open the oil filler cap on the left side of the body, and remove the dipstick.
Slowly add the recommended model of engine oil (SAE 10W-30) and check the dipstick while adding until the oil level is between the “L” (lowest) and “H” (highest) marks (not exceeding the “H” mark to avoid excessive oil accumulation and oil leakage).
Tighten the oil filler cap and dipstick, and wipe off any remaining oil with a dry cloth.
Add fuel:
Unscrew the fuel tank cap (counterclockwise) and clean the impurities around the fuel inlet.
Add unleaded gasoline with a fuel level not exceeding the red limit ring inside the fuel tank, and tighten the fuel tank cap (clockwise).
Check for leaks at the connection between the fuel tank and oil pipe. If there is any overflow, wipe it clean immediately.
Battery connection:
Find the battery quick connector on the side of the body (red positive pole, black negative pole), align the battery connector with the body connector and insert it. When you hear a “click” sound, it will lock (the connector is pre installed at the factory and does not require additional wiring).
Turn on the battery switch (to the “ON” position) and check if the control panel data center is lit up (confirm that the battery power supply is normal).
2. Startup process (detailed explanation of three startup methods)
(1) Remote start (recommended, convenient and efficient)
Preprocessing: Confirm that the fuel valve is “ON”, the battery switch is “ON”, all loads are disconnected, and the generator is placed for horizontal ventilation.
Start operation: Press the “START” button on the remote control for 1 second, and release it immediately after the generator starts (do not long press to avoid damaging the starter motor).
Check after startup: After the generator is started, the remote control indicator light will flash, and the data center will display voltage and frequency. Observe that the engine runs smoothly without any abnormal noise.
Cold machine regulation: If the cold machine is started, the generator may run at high speed and wait for 3-5 minutes for the speed to stabilize (automatic regulation).
(2) Electric start (used when there is no remote control or when the remote control fails)
Preprocessing: Same as remote control startup, ensure that all switch positions are correct and the load is disconnected.
Start operation: Press the “START/STOP” button on the control panel for 2 seconds, and release it after the engine starts; If it fails to start once, try again after a 30 second interval (to avoid overheating of the starting motor).
Fault handling: If the startup fails 3 times, check the battery level (possibly low), whether the fuel is sufficient, and whether the spark plug is normal.
(3) Hand pulled start (emergency backup, used when the battery is low)
Preprocessing: Close the air door (push in the air door knob), turn on the fuel valve, turn off the battery switch (no power supply required), and disconnect the load.
Start operation:
Press and hold the generator body with one hand (to prevent vibration displacement), and hold the starting rope handle with the other hand. Slowly pull until you feel an increase in resistance (piston compression stroke), then quickly and forcefully pull the handle.
After starting the engine, slowly return the handle (to avoid rebounding and hitting the body) and gradually open the air door (pull out).
Hot engine start: If the engine has been preheated, there is no need to close the air door, simply pull the start rope.
(4) Stable process after startup
Run without load for 3-5 minutes, allow the engine and generator to fully warm up, observe the data center: voltage 230-250V, frequency 58-62Hz, no fault indicator light on (CO alarm light, low fuel alarm light, etc. are all off).
Check engine sound: The sound is uniform during normal operation and there is no abnormal noise (such as knocking or whistling); If there is any abnormal noise, stop the machine immediately for inspection.
Load connection: According to the principle of “high power first, low power later”, connect the devices one by one, ensuring that the plug is fully inserted during connection to avoid loosening and heating.
3. Monitoring and regulation during operation
Real time monitoring points:
Data center: Regularly check voltage, frequency (fluctuation range should not be too large), and cumulative operating time (remind maintenance cycle).
Indicator lights: CO alarm light, low oil alarm light, overheating alarm light, overload alarm light should all be turned off. If they are turned on, follow the fault handling process.
Fuel gauge: Observe the remaining fuel level and replenish it in a timely manner (to avoid shutting down due to running out of fuel).
Adjustment operation:
If the overload alarm (circuit breaker tripping) is caused by excessive load, immediately disconnect part of the load, press the circuit breaker reset button, and then reconnect.
If the engine speed fluctuates during operation, it may be due to insufficient fuel supply or clogged air filter. Check if the fuel valve is fully open and if the air filter is clean.
Long term operation (exceeding 2 hours) requires regular checks of engine temperature (with no abnormal overheating on the side of the body) to ensure good heat dissipation.
4. Shutdown process (operating in different scenarios)
(1) Normal shutdown
Disconnect all loads (unplug or turn off the device switch).
Run the generator without load for 3-5 minutes to cool down the engine and generator (to avoid direct shutdown due to high temperatures causing carbon buildup).
Press the “START/STOP” button on the control panel for 1 second or the “STOP” button on the remote control to shut down the engine.
Turn off the battery switch (OFF) and fuel valve (OFF).
Close all waterproof covers of sockets and cover with dust covers (if not used for a short period of time).
Press and hold the “START/STOP” button on the control panel for 3 seconds to force a shutdown (without disconnecting the load).
Follow up processing: Investigate the cause of the malfunction (such as fuel leakage, engine noise), eliminate the fault before use, and prohibit restarting without troubleshooting.
(3) Long term shutdown (exceeding 1 month)
Disconnect the load according to the normal shutdown process and run it without load for 1 minute.
Close the fuel valve and allow the engine to continue running until the fuel runs out and automatically shuts down (to avoid fuel deterioration and blockage in the carburetor).
Disconnect the battery connection (unplug the quick connector), fully charge the battery and store it separately (to avoid damage due to low battery).
Clean the dust and oil stains on the surface of the generator, check the condition of the air filter and spark plug, and clean them if necessary.
Inject 1 teaspoon of new engine oil into the cylinder and pull the starting rope 3-5 times (without ignition) to evenly distribute the oil on the cylinder wall (rust prevention).
Cover with a dust cover and store in a dry, ventilated, and cool room (do not store in flammable areas).
Complete maintenance process (including cycle and details)
1. Preparation before maintenance
Safety measures: Turn off the generator, disconnect the battery connection, and allow the engine to cool to room temperature (to avoid high-temperature burns); Operate in a well ventilated area and prepare tools (wrench, oil pan, funnel, wire brush, etc.).

Check:
Appearance: The components are not loose or damaged, and the oil pipes and oil pipe joints are not leaking.
Oil level: The engine oil level is between “L” and “H”, the fuel gauge shows sufficient, and there is no leakage.
Battery: The connection is firm, without bulging or leakage (lead-acid batteries need to check the electrolyte level, and if it is insufficient, add distilled water).
Cable and plug: No damage or aging, and the plug has good contact.
Run every 8 hours (or after each use)
Oil level check: Add oil to the standard level (not exceeding the “H” mark).
Fuel filter inspection: Observe whether there is moisture or impurities in the sedimentation cup. If there are, unscrew the drain screw to drain it, and then tighten it again.
3. Long term storage and maintenance (over 3 months)
Preparation before storage:
Cleaning: Thoroughly wipe off dust and oil stains on the surface of the body, clean up debris from the heat sink and ventilation vents.
Fuel treatment:
Method 1 (Adding Stabilizer): Fill up with fresh fuel, add fuel stabilizer (according to the instructions), start the engine and run for 5 minutes, let the stabilizer circulate to the fuel system, and close the fuel valve and battery switch.
Method 2 (Drain Fuel): Close the fuel valve, unscrew the carburetor float drain screw, and drain the fuel; Unscrew the fuel tank drain screw, drain the fuel from the tank, and then tighten all screws.
Oil change: Change the engine oil according to the procedure (to avoid impurities in the old oil corroding the engine).
Cylinder rust prevention: Remove the spark plug, inject 1 teaspoon of new engine oil into the cylinder, pull the starting rope 3-5 times (without ignition) to evenly distribute the engine oil on the cylinder wall, then reinstall the spark plug and pull the starting rope until the piston is in compression stroke (valve closed to prevent moisture from entering).
Battery handling: Disconnect the battery, store it separately after fully charging, and recharge it every 1-2 months (to avoid battery depletion).
After storage, remove and use:
Remove the dust cover and check the appearance of the generator for any damage or debris.
Connect the battery and check the oil level (replenish if insufficient).
Add fresh fuel (do not use fuel that has been stored for too long).
According to the normal start-up process, the engine may emit smoke for a short period of time (residual oil in the cylinder), which is a normal phenomenon and will disappear after running for 1 minute.
4. Maintain taboos and precautions
Do not use flammable solvents such as fuel or banana oil to clean components (such as air filters and machine bodies) to avoid causing fires.
It is prohibited to mix different brands and models of engine oil, and it is forbidden to use two-stroke engine oil or inferior engine oil (which can damage the engine).
When replacing spark plugs, the recommended model must be used and the tightening torque should not be too high (to avoid damaging the cylinder head threads).
When cleaning the air filter, do not twist or tear the foam filter element, and do not wash the paper primary filter with water (only air blowing).
After all maintenance operations, it is necessary to ensure that the components are securely installed and the screws are tightened to avoid detachment during operation.

3. Function analysis of the trip unit
(1) Amptector II-A (Standard Type)
Adjustable parameters:
Long delay: Current 0.5-1.25 times the rated value of the sensor, time 8-36 seconds (at 6 times the rated current).
Short delay: current 4-10 x sensor rated value, time 0.18-0.5 seconds.
Instantaneous: current 4-12 times the rated value of the sensor, without delayed tripping.
Core function: Covering basic protection against overload and short circuit, supporting three combination modes: DU (long delay+instantaneous), SE (long delay+short delay), and TR (triple protection).
Operation qualification: Only personnel with low voltage distribution operation qualification are allowed to install and maintain, and they need to be familiar with equipment structure, interlocking mechanism, and electric shock risk.
Protective equipment: Insulated gloves and goggles must be worn during operation, insulated shoes must be worn, and slippers, bare feet, or loose clothing are prohibited (to avoid getting caught up in mechanical parts).
Prohibited behavior: Unauthorized personnel are prohibited from operating; It is prohibited to dismantle the arc extinguishing chamber and insulation barrier during equipment operation; Prohibit blocking or modifying interlocking devices (which may cause equipment misoperation and lead to accidents).
2. Installation and wiring safety
Pre installation inspection:
Check the nameplate parameters (voltage, current, breaking capacity) to match the system, and confirm that the circuit breaker is not damaged during transportation (contacts, arc extinguishing chamber, interlocking components are intact).
The drawer type circuit breaker needs to check that the guide rail and rocker are not deformed, and that the energy storage spring is not fatigued or corroded.
Wiring specifications:
Main circuit wiring: The tightening torque meets the requirements (copper bars/cables need to be crimped to the terminals) to avoid loosening and heating; The cross-sectional area of the three-phase wires is consistent, and the phase correspondence is correct.
Control circuit wiring: The electric operation type needs to be connected to a compliant control power supply (AC120/240V or DC48/125/250V), and the connection between the trip unit and the actuator should be firm with correct polarity (otherwise the protection function will fail).
Grounding requirements: The circuit breaker frame must be reliably grounded with a grounding resistance of ≤ 4 Ω to avoid electric shock caused by leakage.
3. Operation and operational safety
Working position operation:
Remove position: only used for maintenance or replacement. The energy storage spring must be released first, and all power sources must be disconnected. It is forbidden to remove it while it is still live.
Disconnect position: Both the main and auxiliary contacts are disconnected, which can be locked to prevent misoperation and is used for isolation and maintenance.
Test position (TEST): The auxiliary contact is connected, which can test the closing/tripping action and tripping function. The main circuit is not powered.
CONNECT: Normal operating position, it is necessary to confirm that the mechanical stop is in place, the interlocking device is locked, and it is prohibited to switch positions in the closed state.
Energy storage and closing operation:
Manual energy storage: DS-206 and other models require a single stroke downward pull on the energy storage handle, while DS-416 and above require multiple presses on the ratchet wheel. After energy storage is completed, there will be a “click” sound and the spring energy storage indicator light will light up.
Electric energy storage: After connecting to the control power supply, the circuit breaker will automatically store energy in the test/connection position. In case of energy storage failure, emergency manual energy storage can be used.
Closing taboos: Do not close with load; Do not repeatedly close the circuit when the short circuit fault has not been resolved; Do not close the circuit with current exceeding the nameplate.
Fault handling safety:
Troubleshooting after tripping: Overload tripping requires reducing the load, short-circuit tripping requires troubleshooting for line faults, grounding faults require checking the grounding circuit, and DSL series requires confirming whether the current limiting element is blown.
Emergency stop: In the event of a serious malfunction, emergency stop can be achieved through the panel trip button or remote trip signal, and forced locking and closing are prohibited.
4. Environment and Protection Safety
Operating environment: It is necessary to maintain dryness, cleanliness, good ventilation, avoid dust, oil mist, corrosive gases (such as chlorine and ammonia), and prevent contact oxidation and insulation aging.
Temperature control: When the ambient temperature exceeds 40 ℃, it is necessary to reduce the capacity (reduce the capacity by 10% for every 10 ℃ increase), and avoid direct sunlight or proximity to heat sources.
Moisture prevention measures: Insulation inspection should be strengthened in humid environments, and insulation resistance should be measured regularly (main circuit ≥ 1M Ω, control circuit ≥ 2M Ω).
Complete operation process (installation → debugging → maintenance)
1. Installation process (drawer style as an example)
Guide rail preparation: Open the circuit breaker cabinet door, unfold the built-in guide rail to a horizontal position, and ensure that the guide rail is not deformed or stuck.
Remove transportation fixing: Remove the transportation bracket and plastic protective cover on the circuit breaker, and check that the energy storage spring is not preloaded (released during transportation).
Push in the circuit breaker: Align the circuit breaker with the guide rail, slowly push it into the extraction position, insert the joystick and rotate it clockwise to switch to the disconnection position, test position, and connection position in sequence. Each position needs to be confirmed to be mechanically locked in place (with a “click” sound).
Wiring operation:
Main circuit: Connect the incoming and outgoing copper bars according to the phase, tighten the bolts (refer to the equipment manual for torque), and check the balance of the three-phase resistance.
Control circuit: Connect control power supply, remote closing/tripping signal, tripping unit power supply, check wiring diagram to avoid reverse polarity connection.
Grounding: Connect the grounding terminal of the circuit breaker frame reliably to the cabinet grounding bar.
Insulation test: Use a 500V megohmmeter to measure the insulation resistance of the main circuit. A resistance of ≥ 1M Ω is considered qualified, otherwise moisture or wiring faults need to be investigated.

Replace nozzle: After turning off the power and releasing the pressure, remove the current nozzle and install the soap nozzle.
Cleaning operation:
Turn on the water source and power, press the trigger, and wait for 3-5 seconds (to allow the cleaning agent to be sucked into the pipeline) until the water flow contains the cleaning agent.
Spray at a uniform speed onto the dry surface, ensuring even coverage of the cleaning agent, and let it sit for 1-2 minutes (do not dry out).
Turn off the power, replace with a 25 ° nozzle, turn on the water source and power, rinse the surface with clean water until there is no residue of cleaning agent.
Follow up processing: Empty the soap box, pour in clean water, install a soap nozzle, press the trigger to flush the pipeline for 1 minute to avoid blockage caused by residual cleaning agents.
3. Daily maintenance and regular maintenance
(1) Maintenance after each use (completed within 5 minutes)
Cleaning nozzle: Remove the nozzle, use specialized cleaning tools or fine needles to clean impurities (such as mud, residue of cleaning agent) in the nozzle hole, and then rinse with clean water.
Cleaning the inlet filter: Unscrew the inlet connector, remove the filter, rinse it with clean water, and reinstall it to ensure that the filter is not damaged (missing the filter can cause impurities to enter the pump body and cause wear).
Drain residual water from the pipeline: Turn off the water source, press the trigger to release residual water, disconnect the high-pressure hose and garden hose, tilt the machine body to drain the accumulated water in the inlet.
Cleaning the body: Wipe the dust and stains on the surface of the body with a damp cloth, do not rinse the body with high-pressure water flow (to avoid water ingress to electrical components), and do not use corrosive cleaning agents such as gasoline and solvents.
(2) Regular maintenance (monthly/every 20 hours of use)
Check the high-pressure hose: Check whether the hose is damaged, bulging, loose joints, and whether the sealing ring is aging (if there is water leakage, replace the sealing ring or hose).
Lubrication sealing ring: Apply a small amount of non water soluble grease (such as Vaseline) on the sealing ring of the high-pressure hose joint and spray gun interface to extend the service life of the sealing ring.
Test GFCI plug: Follow the steps of “leakage protection maintenance” mentioned earlier to ensure that the protection function is normal.
Check nozzle wear: If the nozzle hole becomes larger and the spraying direction deviates, it indicates that it has been worn and needs to be replaced (wear can cause a decrease in pressure and cleaning efficiency).
(3) Long term storage and maintenance (not used for more than one month)
Thoroughly clean: Follow the “maintenance after each use” steps to clean the nozzle, filter screen, and pipeline, ensuring that there is no residual cleaning agent.
Drain water: Disconnect all pipelines, press the trigger to release residual water in the pump body, and tilt the machine body for multi angle drainage.
Pump body protection: It is recommended to use commercial pump body protectants (operate according to the instructions) to prevent the pump body seals from drying out and rusting inside.
Storage requirements:
Store in a dry, ventilated, and heated room with a temperature not lower than 4.5 ℃ (to prevent residual moisture from freezing and expanding, which may cause the pump body to crack).
Disassemble the nozzle, spray gun, and extension rod, clean them and place them in the storage rack. Wrap the high-pressure hose and cable neatly to avoid squeezing or bending.
Stay away from flammable materials, high temperature sources (such as heating, stoves), and corrosive gas environments.

2. Compatibility requirements
Only compatible with Westinghouse generators with “Smart Switch Ready” interface, not compatible with other brands or generators without this interface.
Do not use in series with other conversion switches, do not connect GFCI sockets or use socket adapters.
Core functions and working principles
1. Full process working mechanism
(1) When the power grid is normal (standby mode)
Power supply path: grid power supply → transfer switch → connected electrical appliances. At this time, the green “grid power indicator light” is constantly on.
Additional function: The generator battery is continuously charged by the power grid through the generator control cable, ensuring that the generator battery is fully charged and can be started at any time.
Key state: The generator is in the “RUN” position but not starting, only the battery charging circuit is working.
(2) When the power grid is cut off (emergency power supply state)
Trigger mechanism: When the conversion switch detects a power outage in the power grid, the red “power grid interruption indicator light” immediately lights up.
Start up process: After a delay of 5-10 seconds (to avoid accidental triggering due to instantaneous fluctuations in the power grid), send a start signal to the generator through the control cable, and the generator will automatically start and enter a stable operating state.
Switching power supply: After the generator output stabilizes (within about 30 seconds), the transfer switch automatically cuts off the power grid circuit and connects the generator power supply circuit. The green “generator power indicator light” lights up, and the electrical appliances are powered by the generator.
(3) When the power grid is restored (switching and cooling state)
Detection process: After the power grid is restored, the transfer switch first undergoes a 5-10 second stability test (to prevent frequent switching caused by voltage fluctuations in the power grid), and at this time, the red and green indicator lights are constantly on.
Switching power supply: After confirming the stability of the power grid, cut off the generator power supply circuit, connect the power grid circuit, the red “power grid interruption indicator light” will turn off, and the electrical appliances will resume power supply to the grid.
Cooling shutdown: The switch keeps the generator running for 45-50 seconds during the cooling period to avoid damage to the engine caused by high-temperature shutdown. After the cooling is complete, the generator will automatically shut down and the green “generator power indicator light” will turn off.
2. Full analysis of indicator lights (including abnormal states)
Description of indicator light combination status and operation suggestions
Only the green grid light stays on and is in normal standby mode. The power is supplied by the grid, and there is no need to operate the generator battery during charging. Regularly check the cable connections
Only the red power grid interruption light remains on. The power grid has been cut off, and we are waiting to start the generator to confirm that the fuel and oil are sufficient and there are no fault alarms
Only the green generator light is constantly on, and the power grid has not been restored to monitor the operation status of the generator to ensure sufficient fuel supply
The traffic lights are constantly on at the same time, and the power grid has been restored. Stability testing will be conducted and wait for 5-10 seconds without manual intervention
The green light stays on and the red light flashes. The power grid is restored but the voltage is unstable. Keep observing. If it does not return to normal within 1 minute, check the power grid line
The generator light is constantly on+the grid light is flashing. The generator power supply is normal, and the grid is in a fluctuating state without operation. The transfer switch will continue to monitor the grid
No indicator light is on, the conversion switch is not connected to the power grid, or there is an internal fault. Check if the power grid connection line is tightly plugged in. If the connection is normal, it needs to be reported for repair
It must be placed in an outdoor ventilated area, at least 15 feet (about 4.6 meters) away from the doors, windows, and ventilation openings of the house, to prevent carbon monoxide exhaust from entering the room.
Place on a hard, level surface to avoid tilting and causing fuel leakage; Keep a safe distance of at least 3 feet (approximately 0.9 meters) away from flammable materials such as hay, wood, and paint.
It is prohibited to place the generator on rainy, snowy, or damp ground. A temporary rain shelter (not enclosed) must be built to prevent rainwater from entering the generator and causing a short circuit.
Requirements for placement of transfer switch:
Only suitable for indoor use, placed in a dry, ventilated, away from water sources (such as kitchens, bathrooms) and flammable materials.
Do not place it in areas prone to water accumulation such as basements and low-lying areas to avoid equipment short circuits caused by floods or water leaks.
The placement height should be at least 1 foot (about 0.3 meters) above the ground to prevent moisture erosion on the ground.
2. Cable connection safety
Connection sequence: The power grid must be connected first, then the generator control cable, and finally the generator power line. It is forbidden to reverse the sequence.
Cable requirements:
Grid input extension cable: A grounded three core cable with no damage or aging is required, with a length not exceeding 30 feet (approximately 9.1 meters) and a core cross-sectional area of ≥ 1.5mm ².
Generator control/power cord: The total length should not exceed 50 feet (approximately 15.2 meters). If extension is required, Westinghouse original extension cords (model 3021225C is the power cord extension cord, STCORD25 is the control cable extension cord) must be used. Non original cables are prohibited.
Connection operation:
All connections must be made after the generator is turned off and cooled down, and the plug must be fully inserted into the interface and locked to avoid loosening and overheating.
After connection, check that the cables are not twisted or compressed, and keep them away from high-temperature components such as the generator exhaust pipe to prevent cable aging.
3. Safety of electrical loads
Load accounting rules:
Pure resistance load (light bulb, heater, rice cooker): total operating power ≤ 20A × 120V=2400W.
Inductive loads (motors: refrigerators, water pumps, air conditioners): starting power=operating power multiplied by multiple (small handheld devices multiplied by 1.2, large fixed devices multiplied by 3.5), total starting power ≤ 2400W.
Example: 1500W space heater (pure resistor)+700W refrigerator (starting power 700 × 3.5=2450W), total starting power 2450W>2400W, cannot be connected simultaneously; 1500W heater+500W furnace (starting power 500 × 1.2=600W), total starting power 2100W ≤ 2400W, can be connected simultaneously.
Taboo for load connection:
Prohibit the connection of electrical appliances with unknown power to avoid overload triggering circuit breaker tripping.
It is prohibited to simultaneously connect multiple large inductive loads (such as two air conditioners, one water pump+one air conditioner) to prevent excessive starting power.
When connecting electrical appliances, it is necessary to first turn off the electrical switch and then turn it on again to avoid arcing caused by load insertion and removal.
4. Emergency safety handling
Generator malfunction unable to start: Immediately disconnect the transfer switch from the generator, manually start the generator to troubleshoot (such as low fuel, low oil, spark plug malfunction), and reconnect after troubleshooting.
The transfer switch does not switch the power supply: check the status of the indicator light. If the red light is on after the power grid is cut off but the generator does not start, check the connection of the control cable; If the green light does not turn on after the generator is started, check the power cord connection and restart the transfer switch if necessary (unplug the power grid for 30 seconds and then reinsert it).
Fire/Leakage Emergency: Immediately shut down the generator, unplug all connecting wires of the transfer switch, and use ABE or BE class fire extinguishers to extinguish the fire (water is prohibited from extinguishing electrical fires); If electric shock occurs, immediately cut off the power and seek medical attention.
Operation process (setup+testing+daily use)
1. Initial process setup (required steps)
Generator preparation:
Place the generator in a safe outdoor location, check that the fuel (unleaded gasoline) and engine oil (four stroke engine oil that meets the requirements of the generator) levels are normal, and that the battery connection is secure.
Start the generator and test it to run normally independently. After confirming that there are no fault alarms, turn it off and cool it down to room temperature.
Switch connection:
Place the transfer switch in a dry indoor location, connect the grid power supply to the “grid power input port” of the transfer switch with a grounding extension wire, and the green grid indicator light will light up at this time.
Connect the generator control cable: Insert one end into the “Smart Switch Ready” interface of the generator and the other end into the “Control Cable Interface” of the conversion switch. You can hear the locking sound of the buckle.
Connect the generator power cord: Insert the 25 foot power cord L14-30P plug that comes with the conversion switch into the generator L14-30R socket, and tighten the fixing nut.
Electrical connections and generator settings:
Connect the electrical appliances that require emergency power supply (such as refrigerators and heaters) to the 120V dual socket of the conversion switch to ensure that the total power does not exceed the standard.
Turn on the “RUN” switch of the generator, confirm that the generator battery indicator light is on (indicating that the charging circuit is normal), and complete the first setting.
2. Functional testing process (must be done before first use)
Test purpose: To verify that the automatic switching function of the transfer switch is normal and to avoid failure in emergency situations.
Test preparation: Ensure all connections are complete, connect a small appliance (such as a desk lamp, phone charger), and confirm that the appliance is powered by the power grid normally.
Simulated power-off test:
Unplug the power grid input extension line of the conversion switch and simulate a power outage in the power grid.
Observe the indicator light: The red power grid interruption light will immediately turn on, and the generator will automatically start after 5-10 seconds.
Confirm switch: About 30 seconds after the generator starts, the green generator light will turn on, and the electrical appliances will be powered by the generator normally.
Simulated recovery test:
Re insert the power grid input extension line to simulate power grid recovery.
Observe the indicator lights: both traffic and green lights remain on (5-10 second detection period), then the red light goes out and the electrical appliances resume power supply to the grid.
Confirm shutdown: Wait for 45-50 seconds, the generator will automatically shut down, the green generator light will turn off, and the test is complete.
Exception handling: If a step in the test is not executed as expected, check if the cable connection is secure and if the generator is in the “RUN” position. After troubleshooting, retest.
3. Daily use and emergency activation process
(1) Daily maintenance (non emergency state)
Every month: Check if all cable connections are secure, without damage or aging; Start the generator and run it for 10 minutes to ensure that there are no faults in the generator.
Every 6 months: Conduct a complete test of the transfer switch according to the “functional testing process” to ensure that the automatic switching function is normal; Check the battery level of the generator and recharge it if necessary.
Long term use (exceeding 3 months): Disconnect the transfer switch from the power grid and generator, store the transfer switch in a dry environment, and maintain the generator according to long-term storage requirements.
(2) Emergency use (sudden power outage in the power grid)
No manual operation required: The switch automatically completes the entire process of “detecting power failure → starting the generator → switching power supply”.
Key monitoring: Observe the status of the conversion switch indicator light and confirm that it switches as expected; Monitor the fuel level of the generator and replenish fuel if necessary under safe conditions (operate after shutting down the generator and cooling it down).
After the power grid is restored: without intervention, the transfer switch automatically switches back to the grid and shuts down the generator. After the generator cools down, its “RUN” switch can be turned off (or kept on for the next emergency start).

3. Function and position of core components
Air filter: located on the right side of the body, filters dust from the intake air to prevent engine cylinder wear; Regular cleaning is required, and the cycle should be shortened in dusty environments.
Spark plug: located on the left side of the body, it generates an electric spark to ignite the fuel mixture; Carbon deposition or wear can cause difficulty in starting and unstable operation.
Spark arrester: installed at the outlet of the muffler to prevent sparks from escaping and causing fires; When used in outdoor or dry environments, it is necessary to ensure cleanliness and smoothness.
Fuel filter: located below the fuel inlet inside the fuel tank, filters impurities in the fuel to avoid clogging the fuel injectors.
Oil inspection cover: on the left side of the body, open to check or add oil; The oil filling port is threaded, so avoid over tightening and damaging the threads when tightening.
Fuel emission hose: located at the bottom of the left side of the aircraft, used to drain the fuel from the tank (such as during long-term storage or when the fuel deteriorates).
Safety operation rules (including risk avoidance)
1. Environmental safety requirements
The operating position should meet the following requirements: good outdoor ventilation, away from doors, windows, ventilation openings, tents, etc. (to prevent the accumulation of carbon monoxide); The ground is flat and hard (to avoid vibration and tilting during operation, which may cause fuel/oil leakage); Maintain a distance of at least 1.8m from combustible materials such as wood, hay, paint, etc., and maintain a heat dissipation space of at least 0.5m from other equipment.
Prohibited from use in the following scenarios: confined spaces (indoor, garage, basement), damp ground (waterlogged, muddy), thunderstorm weather, and high dust concentration environments (such as construction site dust areas).
Extreme environmental response: When operating at high temperatures (>35 ℃), it is necessary to operate in a cool place and avoid direct sunlight; When the temperature is low (<0 ℃), winter specific engine oil (such as 5W-30) should be used, and the engine block can be preheated before starting (to avoid open flame heating).
2. Fuel safety operation
Preparation before refueling: Turn off the engine and wait for at least 10 minutes for it to cool down (the muffler temperature can reach over 400 ℃, which can easily ignite the fuel); Clean the oil around the fuel filler to prevent impurities from entering the fuel tank.
Refueling operation: Use a dedicated refueling pot to slowly refuel, with the oil level not exceeding the red limit ring in the fuel tank (reserve 5-10% expansion space); If fuel spills, immediately wipe it clean with a dry cloth and wait for it to evaporate before starting the engine.
Fuel storage: Backup fuel should be stored in a qualified fuel container, in a ventilated, cool, and away from sources of fire, for a period of no more than 3 months (with the addition of fuel stabilizers, it can be extended to 6 months).
Forbidden operation: Do not refuel while the engine is running; Prohibit using fuel to clean equipment; Do not place fuel containers on the generator or near heat sources.
3. Electricity safety regulations
Extension cable selection: 240V AC extension cables must comply with AS/NZS 3199:2007 standards, using 15A heavy-duty three core cables (core cross-sectional area ≥ 1.5mm ²), with a length not exceeding 25m (1.5mm ²) or 40m (2.5mm ²); The length of the 12V DC extension cable shall not exceed 3.5m, and the cross-sectional area of the wire core shall be ≥ 1.0mm ².
Load calculation method:
Pure resistance load (light bulb, heater, rice cooker): starting power=operating power, total operating power ≤ 2100W.
Inductive loads (air conditioning, water pump, motor): starting power=operating power x 1.2 (small portable equipment) or 3.5 (large fixed equipment), total starting power ≤ 2400W.
Example: 1.5kW air conditioner (operating power 1500W), starting power=1500 × 3.5=5250W>2400W, cannot be driven separately; 0.8kW water pump (operating power 800W), starting power=800 × 1.2=960W, can be driven.
Grounding requirements: The generator itself has an equipotential connection system and does not require separate grounding; If connecting fixed equipment or using in humid environments, a certified electrician must connect the grounding terminal to the grounding electrode (such as a metal grounding rod).
Emergency response: In case of equipment tripping, heating, or odor during power consumption, immediately disconnect the load, shut down the generator, and troubleshoot before use.
4. Personnel safety protection
Wear goggles (to prevent fuel splashes and debris from entering the eyes) and gloves (to prevent oil contamination and burns) during operation; Long hair should be curled up to avoid getting caught up in moving parts.
Children and pets are prohibited from entering within a 1m radius of the generator; Operators need to be familiar with the operating procedures and avoid operating under the influence of alcohol or fatigue.
Emergency situation handling: In case of fuel leakage, immediately stop operation, stay away from the scene, and clean up after the fuel evaporates; If a fire occurs, use ABE or BE type fire extinguishers to extinguish it (it is prohibited to directly extinguish electrical fires with water); If you feel dizzy or nauseous after inhaling carbon monoxide, immediately transfer to a well ventilated area and seek medical attention in severe cases.
Step by step operation guide (including key details)
1. Preparation for the first use of the new machine

Oil filling:
Place the generator on a level surface and open the left oil maintenance cover.
Clean the area around the oil filling port with a clean cloth to prevent impurities from entering.
Using the included fuel can, slowly add oil to the bottom edge of the filling port (the oil level should be level with the filling port and not overflow).
Tighten the oil filling plug, close the maintenance cover, and wipe off any remaining oil.
Fuel filling:
Unscrew the fuel cap (counterclockwise) and clean the area around the fuel port.
Add unleaded gasoline of grade 91 or above, with the fuel level not exceeding the red limit ring inside the fuel tank.
Tighten the fuel cap (clockwise), turn the fuel cap vent to the ON position, and check for fuel leaks.
2. Start up process (including differences in cooling/heating)
Step operation content: Key points for starting a cold machine, key points for starting a hot machine
1. Environmental and status confirmation: Outdoor ventilation, flat and dry ground, disconnect all loads and start the refrigeration unit
2. Prepare the fuel system and turn the fuel control switch to ON. Turn the fuel cap vent to ON and start the cooling machine
Adjust the air damper to the START position (fully pulled out) and keep it in the RUN position (pushed in)
4. Start operation: Hold down the generator body with one hand (to prevent vibration displacement), and hold the recoil start handle with the other hand. Slowly pull until you feel an increase in resistance (piston compression stroke), then quickly and forcefully pull the handle. After starting, slowly release it back (to avoid the handle rebounding and hitting the body). The pulling resistance is small and does not require excessive force. Keep running directly after starting
After preheating and adjusting the engine, let it idle for 3-5 minutes, gradually push the throttle to the RUN position, and observe that the instrument voltage stabilizes at around 240V without prolonged preheating. After starting, connect a light load
3. Operation and monitoring during operation
Load connection:
Confirm that the generator is running stably and the output indicator light (green) is on.
240V equipment: directly plugged into an AC socket or connected through a qualified extension cord; Ensure that the plug is fully in contact during insertion to avoid loosening and overheating.
12V device: Insert the cigarette lighter plug into the DC socket, ensuring that the plug is securely fastened; The total power shall not exceed 100W.
Operation monitoring:
Real time monitoring of instruments: The voltage should be stable between 230-250V, and the speed should vary with the load (in ECO mode, the lower the load, the lower the speed).
Monitor engine sound: During normal operation, the sound is uniform and there is no abnormal noise (such as knocking or whistling); If there is any abnormal noise, stop the machine immediately for inspection.
Check the indicator lights: both the low fuel alarm light and the overload alarm light should be turned off; If it lights up, follow the troubleshooting process.
load regulation:
To avoid sudden connection of high-power loads (such as air conditioning and water pumps), the load switch should be turned off first, and then gradually turned on after connection.
When multiple devices are used simultaneously, connect the low-power device first and then the high-power device to ensure that the total starting power does not exceed 2400W.
If there is an overload alarm (red light on), immediately disconnect part of the load, wait for 30 seconds, press the reset button, and then reconnect.
4. Shutdown process (including different scenarios)
