If your GMR-32B includes current limiting (often via CT inputs), adjust VR3 so that peak load current stays below 32A.
Operating a three-phase motor on low voltage causes high current draw, resulting in insulation breakdown. The GMR-32B trips the circuit when the supply falls below the specified threshold. 5. Three-Phase Voltage Imbalance gmr-32b phase controller manual
The GMR-32B manual outlines five distinct failure states that the device detects. The unit features built-in LED indicator lights to instantly alert technicians to specific electrical faults. 1. Phase Reversal Protection If your GMR-32B includes current limiting (often via
