FAQ
Q: The LED does not light up and the board cannot be recognized after power-on.A: ① Check whether the 24VDC power supply is normal and ensure terminal wiring is secure without looseness.② Verify the DC-37 cable is properly connected with no bent pins.③ The board may be damaged by static electricity. Replace it with a spare board and take proper anti-static precautions during operation.
Q: AI channel signal fluctuates greatly and is inaccurate.A: ① Check sensor wiring and ensure correct 2/3/4-wire connection, with single-point grounding for the shield layer.② Increase the input filter parameter in software to suppress high-frequency interference.③ Calibrate the channel range to compensate for sensor deviation.
Q: No output or abnormal output from AO channel.A: ① Confirm correct wiring of the output load with no short circuit or open circuit.② Check AO channel configuration in software and ensure the current mode (0-20mA / 0-200mA) matches the load.③ If the output circuit is damaged, send the board for repair or replace it directly.
Q: In TMR redundancy mode, signals are inconsistent and alarms occur frequently.A: ① Ensure all three DC-37 cables are firmly connected with poor contact eliminated.② Reconfigure the signal voting logic in software and adjust the deviation threshold.③ Isolate the faulty single channel and replace the corresponding module.
Q: The board overheats during operation and triggers an over-temperature alarm.A: ① Make sure the cabinet cooling fan works properly with good ventilation, and the ambient temperature does not exceed 70℃.② Maintain sufficient mounting spacing for the board and keep the heat dissipation area unobstructed.③ Board aging or excessive load may cause overheating; reduce channel load or replace the board.
Q: Is it compatible with non-GE sensors or actuators?A: Yes. It is compatible as long as the signal type (voltage/current) and range are matched, and 2/3/4-wire wiring is correctly applied. It is recommended to prioritize devices with standard industrial signals to avoid compatibility issues.
