The controller typically features 5 LED indicators to diagnose the power status:

The GMR-32B is generally maintenance-free. If it fails, replace the unit. Conclusion

Solution: Check main line fuses, circuit breakers, and incoming line voltage at L1 and L2.

Does the job for professionals, but frustrating for anyone without prior phase controller experience. Demands a rewrite with clearer safety callouts and a decision-tree troubleshooting guide.

Adjust the value with the arrow keys and press again to save. Key Parameter Settings Reference Table Parameter Name Description Default Value Adjustable Range P-01 Input Signal Selection

Connecting a motor with an incorrect phase sequence (L1, L2, L3 connected in the wrong order) will cause it to run in the reverse direction, which can be catastrophic for many machines. The GMR-32B immediately checks the phase sequence against its internal reference. If the sequence is incorrect, the "逆相" LED illuminates and the relay , acting instantly (approx. 0.1 seconds) and preventing the equipment from starting.

Monitoring overall line health before branching power to sub-systems.

A: Only for general theory. For pinouts, calibration, and alarm codes, you must obtain the exact GMR-32B manual from the manufacturer.

Closed during a fault event. Wire this path directly to external pilot lights or PLC error inputs to announce a system trip. Visual Diagnostic Matrix (LED Indicators)

Monitors overvoltage, undervoltage, static/dynamic phase loss, phase sequence reversal, and voltage imbalances.

Toggles between phase-angle firing and zero-cross firing. Troubleshooting Guide Quickly identify and resolve common operating faults. No Display: Check incoming line voltage and control fuses.
