: Connect the primary L1, L2, and L3 lines to the relay's input terminals. Control Circuit Integration
The (also known as the COCIS GMR-32B or part number 6060009) is an electronic power supply protection relay designed to safeguard three-phase motors and industrial equipment from electrical faults. This guide serves as a manual for its operation, installation, and technical specifications. Core Functions
Power distribution across all three phases is properly balanced, and the phase rotation is correct. The relay contact remains energized to close your main control loop.

Mira looked at the GMR32B. It hummed louder now, a deeper note, like a cello string wound too tight. She unscrewed the rear panel. Inside, a row of twelve tiny DIP switches sat under a plastic cover labeled . gmr32b phase controller manual
For most heating loads, set S1-3 = OFF (phase-angle), S1-4 = OFF, S1-5 = ON. Burst firing (S1-3=ON) reduces RF interference but may cause flicker in incandescent lamps.
Terminals L1 , L2 , and L3 . These are the main supply input terminals. Connect the three-phase supply lines (R, S, T or A, B, C) directly to these terminals. It is crucial to observe the correct phase sequence as this device will enforce it.
Locate the DIP switches or internal jumper block on the control board (accessible by removing the plastic faceplate cover). Toggle the switch corresponding to your input type: Configures the unit for 4-20mA operation. Switch 2 ON: Configures the unit for 0-10V DC operation.
Route the control circuit power loop through the internal relay contact blocks (utilizing the normally open or normally closed sets based on your schematic). If a fault cuts power, this loop opens, starving the primary magnetic contactor coil of electricity and shutting off line power to your motor.

note that these devices frequently solve recurring tripping issues and prevent the destruction of sensitive motor windings during grid fluctuations. wiring diagram
Apply a thin layer of thermal grease (silicon compound) to the back of the controller's aluminum baseplate.
| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | Control signal issue or SCR shorted. | Check input signal (is it >20mA or >10V?). Check SCR health. | | No Output | Missing control signal or blown fuse. | Measure control terminals. Check input line fuses. | | Erratic Output | Poor connection or feedback loop issue. | Tighten terminals; check for ground loops on signal wire. | | Overheating | Insufficient cooling airflow. | Ensure fan (if equipped) is running; clean dust from heat sink. |
