Basic information of the driver

Product positioning and functionality

1391-DES is a digital programmable single axis AC servo drive that is compatible with Allen Bradley 1326 series AC servo motors. It is mainly used in closed-loop positioning systems such as machine tools and automation equipment (such as IMC S-class and MAX controllers), and supports speed and torque control modes.

Core advantage: It can enable the 1326 motor to exceed the rated speed by 33% -50%, improving equipment accuracy and production efficiency; Equipped with encoder output (AQB), providing position feedback signals of 256/512/1024/2048 lines per revolution, compatible with positioning controllers.

Model and Key Parameters

Model classification: Divided by continuous current, it is 1391-DES15 (15A), 1391-DES22 (22.5A), and 1391-DES45 (45A), all of which have the same physical dimensions but different electrical parameters.

Core electrical parameters: rated DC bus voltage of 300V DC, peak current twice the continuous current (such as DES45 peak 90A), modulation frequency of 2500Hz ± 10%, speed regulation accuracy of 0-0.05% (under 95% load variation), operating temperature of 0-60 ° C, no need to reduce capacity at altitude ≤ 1000 meters.

Standard configuration and optional features

Standard functions: Input transient voltage protection, built-in circuit breaker, DC bus shunt regulator (dissipating regenerative energy), 2-row LCD display and programming panel, torque feedforward differential input, microprocessor control board (easy to disassemble and troubleshoot).

Optional functions: Contactor auxiliary switch (for motor braking control or status indication), external shunt resistor (suitable for high regenerative energy scenarios, such as optional 386W external resistor for 22.5A drivers), speed/current monitoring output, anti backlash control, linear acceleration/deceleration module (CR-APG-001, supports 4 preset speeds).

Working principle

Core Circuit and Energy Processing

Power Conversion: Convert 3-phase 50/60Hz AC power into 300V DC bus voltage through a rectifier bridge, and then output variable voltage AC power through a PWM inverter to control motor speed and torque.

Regenerative braking: The regenerative energy generated during motor deceleration will increase the DC bus voltage. When the shunt regulator detects that the voltage exceeds the threshold (386.4V DC), it triggers the chopper transistor to conduct, converting the energy into thermal energy through the braking resistor to avoid bus overvoltage tripping (overvoltage protection threshold 405V DC).

control logic

Closed loop control: By using a motor resolver (rotary transformer) to provide feedback on the rotor position, combined with speed/torque commands, and adjusting through current and speed loops, precise control is achieved; The current loop adopts analog control, and the speed command supports ± 10V DC analog input.

Start stop mode: includes three modes: dynamic braking (bus discharge braking when the contactor is disconnected), regenerative braking (reverse torque braking when the enable signal is disconnected), and free parking (driver disconnection output in case of fault, motor inertia parking).

Installation and wiring

Installation requirements

Environment: It needs to be installed in a closed cabinet, and ventilation should be filtered/cooled to avoid oil mist, dust, and corrosive gases; Vertical installation, distance between single driver and motor ≤ 3m, distance between main driver and frequency converter ≤ 3m when multiple drivers, distance between sub drivers and main drivers ≤ 1.5m, equipment spacing ≥ 304.8mm (to ensure heat dissipation).

Grounding: The driver housing needs to be reliably grounded, and signal grounding (such as resolver, control signal) should use a “star grounding” to avoid introducing noise into the grounding loop.

Wiring specifications

Power wiring: The motor power lines (TB5-1~3) and input power lines (TB5-4~6) need to be twisted pair, separately threaded through pipes, and the wire diameter should refer to the manual (such as 8AWG/6mm ² for DES45); The external shunt resistors (TB5-8~10) need to be matched according to the model (for example, a 45A driver requires an external 5 Ω resistor).

Signal wiring: Control signals such as speed command (TB2-1~2), enable signal (TB2-9~10), reset signal (TB2-11), etc. require 18AWG twisted pair cable with a distance of ≥ 304.8mm from the power line; resolver wiring (TB1-1~10) requires shielded wire with the shielding layer grounded at one end.

Switch and jumper settings

Split regulator duty cycle switch (SW1): adjusts the overheat protection threshold of the braking resistor, and different drivers correspond to different gears (such as setting it to “F” gear when DES22 is equipped with an external resistor).

AQB encoder output switch (S1): Select the number of output lines (256/512/1024/2048), which should match the parameters of the positioning controller (such as halving the number of lines for IMC classic controllers).

Programming and Debugging

Parameter hierarchy and operation

The parameters are divided into three levels: View level (only viewing the operating status, such as speed and current), Modify level (configuring system parameters, such as speed limit and current loop gain), and Maintenance level (advanced parameters, such as inertia compensation and friction compensation), which need to be unlocked through specific key combinations (such as simultaneously pressing the up/down/left arrow+Enter key for Maintenance level).

Core parameters: simulated speed gain (parameter 211, default 500rpm/V, can be calculated based on “maximum motor speed/maximum command voltage”), speed limit (parameters 144/145, default 10% higher than motor rated speed), current limit (parameters 156/157, default 300% motor rated current).

Start debugging process

Preliminary inspection: After confirming that the wiring is correct, power on to verify that the control voltage (± 12V DC,+5V DC) and bus voltage (300V DC) are normal and there are no fault alarms.

Guided start: When powered on for the first time, the driver automatically guides the motor model selection, rotation test (verify motor wiring, rotate clockwise/counterclockwise for 5 seconds each), and zero speed offset calibration (automatically eliminate command offset).

Auto Tune: Starting with parameter 190, the driver automatically measures the system inertia and friction coefficient, calculates the optimal speed loop gain (Kp/Ki), and is suitable for most scenarios; Manual tuning requires adjusting parameters 168 (proportional gain) and 169 (integral gain) to control the speed response overshoot within 20% -30%.

Troubleshooting and Maintenance

fault diagnosis

Fault indication: Front LED light (STATUS light flashing red=fault, green constant light=normal; ENABLE light on=driver enabled), LCD displays specific fault codes (such as “amp overttemp”=driver overheating, “resolver loss”=rotary transformer fault).

Common troubleshooting:

Overvoltage fault: Check whether the input voltage and shunt resistor are open circuited/selected incorrectly, and whether the load inertia is too large;

Rotating transformer fault: Check if the resolver wiring is loose/reversed, and if the cable length exceeds 600 feet;

Overcurrent fault: Check if the motor is short circuited, if the current limit parameter is set too low, and if the load is stuck.

Maintenance points

Regular inspection: clean the cooling fan, confirm that the wiring terminals are not loose, and that the braking resistor has no signs of overheating;

Component replacement: The fuse should be replaced according to the manual model (such as Bussmann KLM10 10A/500V for DES15), avoiding using alternative models; When replacing the control board, pay attention to ESD protection (wear an anti-static wristband).

Installation and Wiring Guide

1. Installation requirements

Size and weight: There are significant differences in the size of drivers with different frames (A1-G). Taking IP20 (NEMA Type 1) as an example, A1 frame size is 215.9 × 290.0 × 160.0mm (width × height × depth), weighing 4.31kg; G frame size is 635.0 × 2324.1 × 508.3mm, weighing 453.6kg (please refer to the specific frame size table).

2. Wiring specifications

Power wiring (TB1 terminal): input terminals R (L1), S (L2), T (L3), output terminals U (T1), V (T2), W (T3), DC bus terminal+DC/- DC, grounding terminals PE (protective ground), TE (shielding ground); 75 ℃ copper wire is required, with different wire diameters for different frame terminals (maximum 5.3mm ²/10AWG for A1-A4 frame, maximum 303.6mm ²/600MCM for G frame), and torque must comply with specifications (such as 1.81N/m/16lb in for A1-A4 frame).

Control and signal wiring:

2. Capacity reduction guide

When the operating conditions of the drive exceed the rated range, it is necessary to reduce the capacity. The core scenarios for reducing the capacity include:

Altitude: When it exceeds 1000m, the capacity decreases by about 6% for every 1000m increase (refer to Figure AD).

When the ambient temperature exceeds 40 ℃, the capacity will decrease by about 2% for every 1 ℃ increase (refer to Figure A-AC).

Carrier frequency: When it exceeds 4kHz (some models are 2kHz), the amplitude should be increased and the capacitance should be reduced according to the frequency (such as reducing the capacitance by 10% at 6kHz).

Product Overview and Core Positioning

1. Product type and applicable scenarios

The 1326AB series is a three-phase brushless permanent magnet synchronous servo motor designed for high-precision motion control, compatible with Allen Bradley 1391 AC servo controller. It is widely used in machine tools, automated production lines, material handling and other scenarios that require precise positioning and high-speed response. It supports various mechanical structures such as screw drive, gear rack drive, conveyor belt drive, etc.

2. Core standard features

Performance Design:

Permanent magnet rotor structure improves servo response speed; Sine wave winding stator achieves low-speed smooth operation and efficient heat dissipation.

Performance parameters and characteristic curves

1. Core performance parameters (typical model examples)

Motor model: Continuous locked rotor torque (lb in/N · m), peak locked rotor torque (lb in/N · m), rated speed (rpm), rotor moment of inertia (lb in s ²/kg-m ²), rated power (kW), continuous current (A)

1326AB-A1G 16/1.8 48/5.4 5000（1391B）/6000（ES/DES） 0.004/0.0005 0.9 4.5

1326AB-B2E 102/11.5 204/23.0（1391B）/279/31.5（ES/DES） 3000（1391B）/4000（ES/DES） 0.05/0.006 2.5 16.4

1326AB-C3E 310/35.0 568/64.1 3000（1391B）/4000（ES/DES） 0.22/0.024 7.5 49.1

1326AB-C4B 420/47.5 840/94.8（1391B）/989/111.8（ES/DES） 1600（1391B）/2000（ES/DES） 0.29/0.032 5.6 38.2

2. Interpretation of speed torque curve

Curve type: divided into two curves: 1391B controller (regular mode) and 1391B-ES/DES (enhanced mode). The peak torque of the former is twice the continuous torque, while the latter can reach three times, and the highest speed is increased (such as A1G from 5000rpm to 6000rpm).

Operating area:

Rated operating zone: Both the motor and controller shall not exceed the RMS rated value, meeting the continuous operation requirements. The calculation formula is:

Torque (T pa=peak acceleration torque, T ss=steady-state torque, T pd=peak deceleration torque, T r=static torque)

Intermittent operation zone: suitable for acceleration and deceleration scenarios, with a duty cycle RMS torque ≤ rated torque to avoid overheating.

Installation and Dimensional Specifications

1. Mechanical installation requirements

Rail adaptation: The A/B/C series both support 35 × 7.5mm DIN rails (models 199-DR1, etc.). The top hook of the module is locked by rotation after being hooked in, and the grounding resistance should be ≤ 2 Ω (detected through the metal shell of the RS-232 port).

Axial load limit: Radial and axial loads must meet the bearing life requirements (B10 life of 15000 hours). Taking the C series as an example, the maximum radial load at 500rpm is 900lbs, and the axial load is 600lbs (refer to the load curve in Figure 8 for details).

2. Key dimensions (taking imperial flanges as an example)

Series length AD (inches) flange diameter O (inches) shaft diameter U (inches) keyway size (inches) with brake length increase (inches)

A1x-11 8.69 4.38 0.625 0.19×0.19×1.38 2.25

B2x-11 13.16 5.88 1.125 0.25×0.25×1.50 2.25

C3x-11 17.38 7.63 1.375 0.31×0.31×2.00 2.5

3. Cable installation

Wiring specifications: Power cables (1326-CPABxx) are wired by color (red=PWR, white=CAN_S, blue=CAN_L, black=COM, bare wire=shielded); The feedback cable (1326 CFUxx) needs to distinguish between the switching signal and the encoder signal, and the shielding layer should be grounded separately.

Bending radius: The standard cable has a single bending radius of ≥ 2 inches (50.8mm), and the high flexibility drag chain cable has a bending radius of ≥ 6.8 inches (172.7mm). Before installation, it needs to be laid flat for 24 hours to release internal stress.

Application Selection and Calculation Guide

1. Selection steps

Determine the speed requirement: Calculate the peak speed of the motor based on the mechanical transmission ratio (for example, if the lead screw is 2 inches and the slide table speed is 400ipm, then the motor speed=400/2=200rpm, with a 20% margin to be reserved).

Calculate continuous torque: Taking screw drive as an example based on load type (friction, cutting force, etc.):

T m=6.28 × e 1 × e 2 × G.R. (W 1 × u+Trust) × Lead × 1.1 (W 1=slide weight, u=friction coefficient, Lead=lead screw, e 1/e 2=lead screw/gearbox efficiency, G.R.=transmission ratio, 1.1 is safety factor)

Verify peak torque: Considering acceleration and deceleration requirements, the calculation formula is:

Peak torque (J total=total moment of inertia, Δ rpm=speed change, t accel=acceleration time, T l=load torque)

Match motor parameters: Ensure that the peak speed of the motor is ≥ the calculated value, the continuous torque is ≥ the required value, and the total inertia is ≤ 5 times the motor inertia (to avoid response lag).

2. Typical application calculation example (screw drive)

Known conditions: slide weight of 500lbs, friction coefficient of 0.05, lead screw of 1 inch, transmission ratio of 1:1, efficiency of 0.9, acceleration time of 0.5 seconds, and speed from 0 to 1000rpm.

Continuous torque calculation: T m=6.28 × 0.9 × 1 (500 × 0.05) × 1 × 1.1 ≈ 5.0 lb in, select A1G (16 lb in) to meet the demand.

Peak torque calculation: Total inertia=sliding table inertia (386500 × (6.281) 2 ≈ 0.0033 lb in ²)+motor inertia (0.004)=0.0073, peak torque=9.6 × 0.5 0.0073 × 1000+0 ≈ 1.52 lb in, which is less than the A1G peak value of 48 lb in and meets the requirements.

Maintenance and safety precautions

Thermal protection: The maximum temperature of the motor winding is 150 ° C (H-class insulation). When the ambient temperature exceeds 40 ° C, it needs to be de rated for use (for every 10 ° C increase, the torque is de rated by 10%).

Brake usage: The brake is only used for static load holding (switching ≤ 90 times per hour) and cannot be used for positioning or frequent braking. The 24V DC brake requires the user to provide their own power supply (0.88-1.2A).

Protection level: IP65 is only applicable to situations with shaft seals and no external feedback/fan. Additional protection is required in humid or corrosive environments.

Troubleshooting: When triggering the thermal switch, it is necessary to first investigate issues such as excessive load and poor heat dissipation. Resetting requires waiting for the winding temperature to drop to 90-100 ° C.

DIP switch configuration (core pre steps)

The DIP switches of the two devices are in the same layout (1203-GK5 is at the bottom and 1336-GM5 is at the edge of the board). They need to be adjusted after power off to take effect after power on. The specific configuration items are as follows:

1. Node address (SW2-1~SW2-6)

Function: Set the DeviceNet network node address (0-63), default is 63, and ensure that the address is unique within the network.

Configuration rule: Binary encoding, SW2-1 is the lowest bit (1), SW2-6 is the highest bit (32), for example, address 3 corresponds to “000011” (SW2-1/SW2-2 is set to ON, the rest are set to OFF).

2. Data rate (SW2-7~SW2-8)

Function: Define DeviceNet communication rate, default 125Kbps, configuration rules are as follows:

|SW2-8 (high bit) | SW2-7 (low bit) | Data rate | Description|

|0 | 0 | 125Kbps | Default value|

| 0 | 1 | 250Kbps | – |

| 1 | 0 | 500Kbps | – |

|1 | 1 | Software configuration | Requires setting through DeviceNet Manager (supports fault node recovery)|

3. Data link (SW1-1~SW1-4)

Function: Enable Datalink (2 input+2 output words per channel, up to 4 channels), default fully disabled, configuration rules:

|Switch | Function | 0 (OFF) | 1 (ON)|

4. Fault response (SW1-6~SW1-8)

Function: Configure device behavior in case of network failure (communication interruption) or controller idle (programming mode), triggering SCANPort product failure by default. Configuration rules:

|Switch | Function | 0 (OFF) | 1 (ON)|

|SW1-8 | Programming/Idle Fault | Triggered Fault | Non Triggered Fault|

|SW1-7 | Communication interruption fault | Trigger fault | No trigger fault|

|SW1-6 | Standby behavior | Output zero data | Maintain last state|

Safety Reminder: Modifying fault response requires risk assessment to avoid personal injury or equipment damage caused by continuous operation of the equipment.

Installation process and electrostatic protection

1. General safety requirements

Static protection: Modules/boards contain ESD sensitive components, and grounding wristbands must be worn during operation, refer to Rockwell document 8000-4.5.2 “Anti static Damage Guide”.

Power off operation: Before installing the 1336-GM5 board, all power sources of the SCANPort product must be disconnected to avoid electric shock; The installation of 1203-GK5 requires disconnecting the DeviceNet network power supply.

2. Installation steps for 1203-GK5 module

Rail mounting: Insert the top hook of the module into the DIN rail, rotate and fasten it, and use an ohmmeter to check the grounding (the resistance between the metal shell of the RS-232 port of the module and the rail grounding is ≤ 2 Ω).

Cable connection:

DeviceNet: 5-pin connector (point-to-point) or 10 pin connector (daisy chain), wired by color (red=PWR, white=CAN_S, blue=CAN_L, black=COM, bare wire=shielded).

SCAnport: Insert the 8-pin mini DIN interface into the cable and confirm installation with a snap sound. The cable length should be ≤ 10m and kept away from high-power cables to prevent interference.

Power on verification: The SCANPort LED is constantly green, and the DeviceNet LED is flashing green (no connection established). If there is an abnormality, refer to the troubleshooting section.

3. Installation steps for 1336-GM5 board

Preparation: Disconnect the power supply of the drive, remove the casing, and install 4 nylon support columns on the drive main control board.

Card fixing: Align the 14 pin pin of the card with the SCANPort interface and insert it, then fix it with 4 screws (to avoid damaging the card due to over tightening).

DeviceNet wiring: Connect 5-pin Phoenix connectors by color, insert them into the card interface, and tighten the screws.

Power on verification: Install the communication enclosure, restore the driver power, keep the SCANPort LED on green, and the DeviceNet LED flashing green.

DeviceNet Network Configuration (DeviceNet Manager)

1. Configuration tools and prerequisites

Software: DeviceNet Manager (Windows application) or RSNetWorx for DeviceNet, requires a 1784-PCD card or 1770-KFD adapter to connect the PC to the DeviceNet network.

Prerequisite: DIP switch configuration has been completed, module/board has been connected to the network, and RSLinx (communication interface software) has been installed on the PC.

2. Core configuration steps

(1) Online mode connection

Start DeviceNet Manager, select “Utilities>Set Up Online Connection”, and choose the corresponding driver (such as 1770-KFD).

Configure communication ports (COM1/COM2), baud rate (default 38400bps), PC node address (avoid 63), network data rate (consistent with DIP switch), click “OK” to enter online mode.

(2) Create EDS file (initial configuration)

Select “Who>Network Who” to scan the network, double-click on unrecognized devices (displaying the universal icon), and a prompt “Create EDS file” will pop up. Click “Yes”.

Click on ‘Load from Device’, enter the module/board node address, automatically load the device description, select the device icon (such as 1336. BMP) and SCANPort adapter icon (SCANPORT. BMP).

Enable “Polled Connection”, set the I/O size (default 4 bytes, formula: 4+number of enabled Datalinks x 4), click “OK” to save, and rescan the network to confirm that the device icon is displayed normally.

(3) Configure PLC/SLC scanner

Taking 1771-SDN (PLC scanner) as an example:

Double click the scanner icon to enter “1771-SDN Module Configuration”, click “Edit Scan List”, select “Add Devices From>Who”, and drag the target node into the scan list.

Select the node, click “Edit I/O Parameters”, and set the polling I/O size (same as EDS configuration) and polling rate (Every Scan/Background).

Click on “Auto Map” to configure the storage address for input/output data (such as PLC N90/N100 files), and click “Map” to complete the mapping.

Select “Save To>SDN”, download the configuration to the scanner, prompt “Scanner offline for 5-10 seconds”, confirm and complete the configuration.

(4) Save and Verify

Save configuration file (for PLC) Used for SL7 and SLC SL4）， Before exiting, confirm that the DeviceNet LED is always green (indicating connection establishment) and the SCANPort LED is always green (indicating normal communication).

Programming and Communication Implementation

1. Ladder diagram programming (RSLogix)

Implementing SCAnport product control through polling I/O requires N-file mapping (input=SCAnport → DeviceNet, output=DeviceNet → SCAnport). Example functions are as follows:

Start stop control: 1336 PLUS driver logic instruction bit definition (bit 0=stop, bit 1=start, bit 2=jog, bit 3=fault clearing), writes the operation signal to the output N-file (such as N10:1) through MOV instruction.

Reference value transmission: The frequency reference value 0-32767 corresponds to 0-maximum frequency, and N7:0 (operator set value) is written to N10:2 (driver reference value) through MOV command.

Status monitoring: Read the drive status bits (bit 1=running, bit 8=fault) from the input N-file (such as N9:1) and output them to the operator display terminal (such as O: 000).

2. Explicit message communication

Support explicit message reading and writing of parameters and fault queries through DeviceNet, following the 8:16 format (8-bit class field+16 bit instance field). The core rules are as follows:

(1) PLC scanner (1771-SDN)

Write the message to the scanner buffer (10 available buffers) using 64 block transfer write (BTW), and retrieve the response through 64 block transfer read (BTR) after completion.

Message format: including transaction ID (1-255), command (1=execute, 2=query status), port (0=channel A), size (in bytes), service code (e.g. 0x0E=get attribute), node address, class/instance/attribute.

(2) SLC scanner (1747-SDN)

Write the message to the M0 file (e.g. M0: 1.224), the scanner processes it and stores the response in the M1 file. After reading, send a “delete command” (command 4) to release the buffer.

Example: Read the number of fault queues (class 0x97, instance 0, attribute 1), store the response data in N20:53, and return the number of fault queue entries.

(3) Safety Tips

Frequent parameter writing through explicit messages can shorten the lifespan of EEPROM. It is recommended to use Datalink to handle high-frequency parameter modifications (Datalink does not write to EEPROM).

Product Overview and Core Positioning

Product Function: As a bridge between the ControlNet network and SCAnport products, the module can convert ControlNet messages into signals recognizable by SCAnport products, supporting the transmission of scheduled I/O data (such as logical instructions, analog reference values) and non scheduled messages (such as parameter read/write, fault query). The ControlNet network speed reaches 5Mbps, ensuring real-time and deterministic performance.

Adaptation scenarios: Compatible with various Allen Bradley SCANPort products, including 1305 AC micro drives, 1336 series inverters (IMPACT/PLUS/FORCE), 1394 multi axis motion control systems, SMC Dialog Plus controllers, etc. Different products support 1-6 peripheral connections, with an I/O word length range of 0-10 words (depending on the product model).

Protection ability: It can resist oil/water flow erosion, prevent cotton wool and dust from entering the shell, and is suitable for scenarios that require environmental sealing.

Connection specifications: The pressure interface is 1/4 “-18 N.P.T.F (American dry sealed cone pipe thread), and the electrical interface includes 1/2” -14 N.P.T (optional Pg 13.5 BS20 specification).

Bellows material: provides two options, each suitable for different media——

Copper alloy corrugated pipe: suitable for water, air, and non corrosive liquids/gases;

316 stainless steel corrugated pipe: suitable for liquids/gases with stronger corrosiveness.

2. Core Structure and Function

Core components: including Top Bellows, Bottom Bellows (mechanical linkage), Contact Block, Adjustment Differential Screw “B”, Pressure Adjustment Difference Bushing “A”, Operation Indicator, optional Pilot Light, etc.

Pressure sensing principle: The action is triggered by the pressure difference between two corrugated tubes, regardless of the actual gauge pressure of the system; Adjustable “trip pressure” and “reset pressure”, with the difference between the two being the “differential control pressure”.

Contact module configuration: provides two specifications to meet different circuit requirements——

Contact module type Contact configuration Circuit function

2-circuit: 1 set of normally open (NO)+1 set of normally closed (NC) supports single pole double throw (SPDT) or independent circuit operation with the same polarity

4-circuit with 2 sets of normally open (NO) and 2 sets of normally closed (NC) supports double pole double throw (DPDT) or two sets of electrically isolated single pole double throw circuits, including isolated terminal 9, which can be connected to external power supply

Working principle

The controller responds to pressure difference changes through a “trigger reset” cycle, with the following specific logic:

1. Trigger (Trip) action (contact switching)

When any of the following conditions are met, the contact module switches states:

The pressure of the bottom corrugated pipe is higher than the preset trigger pressure difference of the top corrugated pipe;

The pressure of the bottom corrugated tube is constant, and the pressure of the top corrugated tube decreases by the preset trigger pressure difference.

2-channel circuit: normally closed circuit (1-2) is open, normally open circuit (3-4) is closed;

4-channel circuit: Two sets of normally closed circuits (1-2, 5-6) are disconnected, and two sets of normally open circuits (3-4, 7-8) are closed.

2. Reset action (contact recovery)

When any of the following conditions are met, the contact returns to its initial state:

The pressure of the bottom corrugated pipe is lower than that of the top corrugated pipe;

The pressure of the bottom corrugated pipe remains constant, while the pressure of the top corrugated pipe increases.

2-channel circuit: normally closed circuit (1-2) is closed, normally open circuit (3-4) is open;

4-channel circuit: Two sets of normally closed circuits (1-2, 5-6) are closed, and two sets of normally open circuits (3-4, 7-8) are disconnected.

3. Key definitions

Trip Pressure: The minimum pressure difference required to trigger contact switching;

Reset Pressure: The maximum pressure difference that triggers contact recovery;

Differential control: The difference between the trigger pressure and the reset pressure can be independently adjusted.

Installation requirements

1. Mechanical installation

Fixing method: It needs to be fixed on a stable base with two screws, and the installation hole specification is “2-17/64” diameter (6.75mm)+2-23/32 “countersunk hole (69mm)”, which can be operated without disassembling the front cover;

Prohibited operation: Do not support the controller solely through electrical or pressure interfaces; When tightening the electrical and pressure interfaces, a support wrench should be used to avoid damaging the components.

2. Precautions for Pre Installation

Before installation, it is necessary to complete the parameter settings (“Setting Control” steps) according to the instructions, otherwise the system cannot be connected;

The pressure interface distinguishes between the “Lower Pressure Bellows Connection” and the “Higher Pressure Bellows Connection”, which need to be connected to the corresponding system.

Parameter setting steps

The factory default setting is “maximum trigger pressure difference+minimum control pressure difference” (adjusting the sleeve “A” about 1 inch from the bottom of the housing), which requires the assistance of a pressure gauge for calibration. It is divided into two steps:

1. Trigger the Difference Pressure Setting

The top corrugated pipe is vented to the atmosphere (without pressure), and a constant pressure is applied to the bottom corrugated pipe to trigger the target pressure difference;

Insert a 1/8 “diameter rod into the hole of the adjusting sleeve” A “, rotate the sleeve to the left until the controller” triggers “(circuit 1-2 is disconnected, circuit 1-2 and 5-6 are disconnected);

At this point, the pressure of the bottom corrugated tube is the set trigger pressure difference.

2. Differential Adjustment Control

Adjustment logic: Adjusting screw “B” only changes the reset pressure difference (does not affect the triggering pressure difference) – turn screw “B” clockwise → increase the control pressure difference (reset pressure difference decreases); Turn counterclockwise → reduce the control pressure difference (reset pressure difference increases); When screw “B” is tightened against the bottom of the front cover, control the pressure difference to be minimized.

Specific steps:

Rotate screw “B” clockwise for about 12 turns;

Apply pressure according to the “trigger pressure difference setting” steps to trigger the controller, then reduce the pressure to the target control pressure difference and maintain it;

Rotate screw “B” counterclockwise until the controller is “reset” (2 circuits 1-2 are closed, 4 circuits 1-2, 5-6 are closed);

Repeat the “trigger reset” cycle several times to ensure stable settings;

Screw “B” should not protrude from the bottom of the housing, and adjusting sleeve “A” should not exceed the control range marked on the dial.

3. Complete the setup

After parameter calibration, connect the top corrugated pipe (low pressure end) to the system, install the front cover and tighten 4 screws (torque 6-8 inch pounds) to ensure sealing. It is recommended to regularly check the system pressure and recalibrate as needed.

Optional accessories and maintenance

1. Pilot Light Options

Specification: High brightness neon lamp, suitable for 120V, 60Hz scenes, can be pre installed in the factory or installed on site;

Ordering method: Add “N9” (such as 836T-XXX-N9) after the existing controller model, special specifications require customization;

Wiring rules:

2-channel circuit: Connect the light wire to the load terminal, connect 1-2 for “on when pressure rises” and 3-4 for “on when pressure drops”;

4-channel circuit: Connect the light wire to the load terminal (1-2/5-6 or 3-4/7-8), or connect it to an external power source through isolation terminal 9 (ensuring the same polarity of the circuit);

Safety reminder: Disconnect the power supply before installation/maintenance to prevent electric shock.

2. Component replacement and maintenance

Contact module replacement: 2-channel module replacement kit model 836T-N1, 4-channel module kit model 836T-N2;

Overall maintenance: As the controller is an integrated structure, it is recommended to return all faults except for the contact module to the factory for repair (the factory will calibrate to the best performance and test according to specifications);

Nameplate protection: The standard controller nameplate comes with a removable protective film, which needs to be removed during final installation.

Safety and Compliance

CE certification: The product complies with CE standards;

Operation warning: Adjust the components within the marked range to avoid mechanical damage; Corrosive media should use 316 stainless steel corrugated pipes to prevent material failure;

WEEE and Environmental Protection: The document does not mention specific environmental compliance information, please refer to Rockwell Automation’s General Environmental Policy.
