Solution: Power down the cabinet and check the torque on all input and output terminals. Tighten any loose screws and inspect the wires for frayed copper strands or insulation degradation.

Protects motors, compressors, and pumps from running backward or running on fewer than three phases, which can cause overheating and catastrophic failure. gmr32b phase controller manual

Excessively high or low incoming voltages trigger the device's automatic overvoltage/undervoltage limits, ensuring the system resets safely. Step-by-Step Installation & Wiring Solution: Power down the cabinet and check the

Switch the positions of L1 and L2 (or L2/L3) at the input terminal. This corrects reversing phase sequence. phase sequence reversal (incorrect phase order)

Detects phase loss, phase sequence reversal (incorrect phase order), and sometimes under-voltage/over-voltage depending on the specific model variation.

One line has dropped zero voltage.
