The (also known as a phase monitoring or sequence relay) is a protection device for three-phase systems. It is primarily used to detect faults such as overvoltage, undervoltage, phase loss, and incorrect phase sequence.
Wire an external switch to trigger smooth ramp-ups. Programming and Parameter Settings
Detects phase sequence errors (incorrect rotation), phase loss, overvoltage, and undervoltage.

The GMR-32B Phase Controller is a high-precision, industrial-grade power control module. It regulates electrical power to resistive and inductive loads by adjusting the thyristor firing angle. This manual provides comprehensive instructions for installing, wiring, programming, and troubleshooting the GMR-32B unit. 1. Safety Warnings and Precautions

Standard HT35 DIN rail mount or direct mounting via two M4 screw holes. Operating Ambient Temperature: -10°C to +55°C. Relative Humidity: 45% to 85% RH.
Connect the outer legs of a 10k-ohm potentiometer to Terminal 1 (+10V) and Terminal 3 (GND). Connect the center wiper leg to Terminal 2 (INPUT+). 4. Programming and Parameter Configuration The (also known as a phase monitoring or
Wire the relay's control output to the contactor coil or motor starter circuit.
The device reacts instantly if any single phase is dropped, whether while the motor is running (dynamic) or completely at a standstill (static). 3. Overvoltage Protection
The NO/NC contacts are typically wired into the control circuit of your motor's magnetic contactor. If a fault is detected (e.g., phases are swapped), the relay will trip, opening the contactor and stopping the motor. Status Indicators:
Verify the external enable switch is closed. It regulates electrical power to resistive and inductive
