Gmr32b Phase Controller Manual =link= Review

Two normally open (NO) and two normally closed (NC) contacts. Connection Capacity: 250VAC 6A or 30VDC 3A. Protection Functions: Phase Reversal: Prevents motors from running backward. Phase Failure (Loss): Trips if any phase is lost. Voltage Monitoring: Over-voltage and under-voltage protection. Voltage Imbalance: Detects significant differences between phase voltages. Installation & Operation Installation: Mount the unit on a and connect the three-phase input ( L1, L2, L3

: Rotating phase lag on L2. Internal thyristor driver overheating. Do not reset. Do not power cycle. Solution: Manual phase rotation via rear-panel DIP switches, followed by a soft calibration (see p. 41). gmr32b phase controller manual
