Verify signal shielding. Ensure sync lines (L1/L2/L3) match the main SCR phase lines. Over-current or Phase Loss detected.
Connect directly to your heating element or motor. Control Terminals
Periodically check terminal screw torques, as thermal cycling in industrial environments can loosen connections over time. gmr-32b phase controller manual
The GMR-32B features onboard trim-potentiometers (trimmers) to fine-tune system performance. Use a small insulated screwdriver to adjust these values.
🤔
What are you using (e.g., 4-20mA, 0-10V, manual dial)?
Cause: Downstream load current exceeded safe operating parameters. Verify signal shielding
The GMR-32B houses multiple dedicated logic diagnostic functions that protect against specific phase anomalies:
Connect the positive control wire to Terminal 2 and the ground wire to Terminal 3. gmr-32b phase controller manual
