To screw the unit flat onto a panel plate, push out the structural mounting tabs on both sides of the base to expose the dual M4 screw holes. Wiring Execution
Safety & Protective Measures (highlights)
Turn this screw to set the baseline power output when your control signal is at its absolute lowest (e.g., 4mA or 0V). This is useful for maintaining a low idle heat in thermal applications.
The (also known as the COCIS GMR-32B) is a monitoring relay designed to protect industrial equipment like motors, air compressors, and elevators from electrical faults. It provides precise detection for phase sequence (reverse phase), phase loss, overvoltage, and undervoltage. Key Specifications gmr32b phase controller manual
The GMR-32B functions primarily as a plug-and-play protector that operates optimally across standard global power grids. Below are its core mechanical and physical operating limits: frequency. Trip Time Thresholds: Phase loss responds in , while phase sequence errors isolate circuits in Voltage Deviations: Tolerates of the configured input voltage.
Improve enclosure ventilation. Clean dust off the heat sink. Check thermal paste. Improper firing mode chosen for an inductive load.
The instructions were absurd. They required him to speak his full name into the controller’s microphone port, then whisper a “regret he had never voiced aloud,” and finally touch the ground terminal to a mirror while humming the resonant frequency of his own childhood home.

The GMR32B Phase Controller requires minimal maintenance, but regular checks should be performed to ensure optimal performance. The following checks should be performed:
Occurs when one of the three lines drops voltage completely. Operating a motor under a missing phase causes severe current overload in the remaining lines, melting winding insulation.
The faceplate of the GMR-32B features diagnostic LEDs to communicate real-time supply conditions: LED Color / State System Status Condition Resulting Output Contact State Action Required / Status Normal Operational State Energized (Closed Circuit) None. Input phases are balanced and correctly sequenced. Solid Red Phase Sequence Error / Reversal De-energized (Open Safety Trip) The (also known as the COCIS GMR-32B) is
note that these devices frequently solve recurring tripping issues and prevent the destruction of sensitive motor windings during grid fluctuations. wiring diagram
Small footprint makes it easy to integrate into existing electrical panels.
Disconnect the main power supply and verify safety with a multimeter. Physically swap the connections at Terminal 1 ( ) and Terminal 2 ( Re-apply electrical power.
