Gmr32b Phase Controller Manual !!link!!

Always disconnect the main power source before servicing the unit.

Connect , L2 to Terminal 2 , and L3 to Terminal 3 . Ensure screws are torqued down securely to avoid loose connections. Step 3: Control Circuit Output Wiring (Low Voltage) gmr32b phase controller manual

Connect the outer legs of a 10kΩ resistor to +5V/Vcc (if provided) and COM , and the wiper to the 0-10V input terminal. Always disconnect the main power source before servicing

Check if the three-phase input power is present at the L1, L2, L3 terminals. LED is showing a fault (Red/Flashing): L2 to Terminal 2

If you need to narrow down a specific operating issue with your controller, tell me:

Secure the unit firmly using M4 or M5 screws to optimize heat dissipation. 3. Wiring Layout and Terminal Connections
