Gmr-32b Phase Controller Manual Jun 2026

Two phases are swapped. You must swap any two of the L1, L2, or L3 input wires to fix the sequence. Phase Loss / Unbalance:

Ensure the main power is disconnected before performing wiring. Verify phase sequence using a separate tester before powering the GMR-32B. gmr-32b phase controller manual

Detects when a phase is missing, preventing motor burnout. Two phases are swapped

Once powered, check the status LEDs. A stable indicator usually means correct operation, while specific flashing patterns indicate faults like phase reversal or imbalance. Visual Reference Verify phase sequence using a separate tester before
