Installation position: Select the installation height based on the specific gravity of the detected gas (heavier/lighter than air), ensuring that the sensor probe is located in an area where gas is prone to accumulate; Need to reserve maintenance space (such as replacing sensors, calibrating operations).
2. Wiring and Connection
Power wiring: Usually powered by 24V DC, attention should be paid to positive and negative polarity;
Signal wiring: Connect to the controller, PLC, or alarm system according to the output type (e.g. 4-20 mA signal lines need to be shielded and grounded to avoid interference);
Terminal block instructions: including interfaces for power supply, signal output, alarm relay, etc., corresponding connections should be made according to the manual markings.
3. Initial setup
After power on, wait for preheating (usually a few minutes) to complete sensor stabilization;

Data reading: transmit the output signal to the control system or view the display screen on site (supported by some models).
2. Calibration and verification
Calibration cycle: It is recommended to calibrate regularly (usually every 6 months) according to the usage environment to ensure detection accuracy;
Calibration steps:
Introduce zero air (such as clean air) for zero calibration;
Perform span calibration by introducing a standard gas of known concentration;
Verify the accuracy of the readings after calibration is completed.
3. Maintenance and upkeep
Sensor maintenance: Regularly check the cleanliness of the sensor, and if the probe is contaminated, use specialized tools to clean it; Sensors have a service life (usually 1-2 years) and need to be replaced upon expiration;
UV lamp maintenance: PID core components need to be replaced regularly (usually 1-2 years) according to manual requirements to avoid detection drift caused by lamp aging;
Shell and interface: Regularly check the sealing of the shell (protection level is usually IP66/IP67) to ensure that the wiring terminals are not corroded or loose.
Troubleshooting
Common faults and solutions (speculation):
No output signal: Check if the power supply is normal, if the wiring is loose, and if the fuse is blown;
Reading drift/inaccuracy: perform calibration; Check whether the sensor is expired or contaminated; Confirm the status of the UV lamp;
False alarm: Check for interfering gases (such as high concentration non target VOCs), calibration failure, or environmental humidity/temperature exceeding the range;
Fault light on: Read the fault code through the device’s self diagnostic function or connection software, and troubleshoot the corresponding manual (such as sensor faults, circuit problems, etc.).
Safety and Compliance
Installation and maintenance should be carried out by professional personnel to avoid live working in explosive environments;
Must comply with relevant safety standards (such as ATEX, UL, IEC, etc., depending on the region and model);
Abandoned equipment should be disposed of in accordance with local environmental regulations to avoid environmental pollution caused by sensors or electronic components.

MC024-010 and MC024-012 are PLUS+1 under Sauer Danfoss ™ Part of the series of mobile machinery management products, it belongs to the universal controller. They are suitable for both distributed machine control systems (where each node has intelligence) and can be used as independent controllers, with characteristics such as flexibility, powerful performance, scalability, and economy.
Product Highlights
MC024-010: Equipped with a digital signal processor (DSP), it has extremely fast single cycle processing speed and built-in 128K flash memory.
MC024-012: Includes application key, compatible with the GUIDE machine control solution developed by Sauer Danfoss.
Two controllers can share the same GUIDE HWD file.
Application development
Users can use Microsoft based ® Windows ® The PLUS+1 GUIDE development environment is used for application development, which features user-friendly and proven icon based graphical programming tools, application downloaders, and service/diagnostic tools.
Main characteristics
Processor and Storage: 32-bit fixed-point DSP, operating at a frequency of 150 MHz.
14 inputs, including 5 universal inputs (can be defined as analog, digital, or frequency inputs), 6 digital inputs, 2 analog inputs (can be used for temperature or rheostat), and 1 fixed range analog input (can be configured as a CAN shield pin).
The analog input range can be configured, the digital input can be configured as pull-up, pull-down, or center pull, and the frequency input range is 1 Hz to 10 kHz.
Output:
Four universal outputs can be defined as digital output (3 A, configurable as source or drain), PWM output (30 to 4000 Hz, configurable as open-loop or closed-loop with current control), or analog voltage output (4000 Hz open-loop PWM).
Any PWM output/digital output/PVGOUT can provide reference power for a PVG valve.
Power and Communication:
9 to 36 Vdc power supply, internal monitoring.
1 CAN 2.0 B port, fixed range analog input can be configured as a shielded pin.
Provide internal regulated power supply of 5 Vdc, 300 mA for external sensors.
Other: 2 user controllable LEDs; 3 installation methods (stacked, end mounted, side mounted); Compliant with CE standards.
