: Visually inspect cooling fans and clean away dust or debris using compressed air.

Use insulated copper wire (1.0~2.5mm²). Ensure the wire is inserted fully (8mm depth) to maintain dielectric strength. Control Circuit Wiring (Output):

These terminals receive the command signals from your PLC, Temperature Controller, or manual potentiometer. Terminal Number Description Signal Ground / Common reference point Terminal 2 Positive input for current loop control Terminal 3 Positive input for voltage control signals Terminal 4 Auxiliary 10V DC output for manual potentiometer power Terminal 5 External Reset (Dry contact to COM clears faults) High-Voltage Power and Trigger Terminals

: Isolate all energy sources before installing or servicing the controller.

Triggers automatically if the incoming source line climbs past the safely tolerated threshold. 5. Undervoltage Protection (Red Indicator) gmr-32b phase controller manual

The GMR-32B is generally maintenance-free. If it fails, replace the unit. Conclusion

It prevents motor operation if phases are connected in the wrong order, which is critical for protecting expensive industrial machinery from running in reverse and causing damage.

Apply control power. The LED should illuminate solidly.

The GMR-32B is engineered for standard industrial power environments with the following typical ratings: 380 VAC Operating Frequency: 50/60 Hz Protection Functions: Phase Sequence: Prevents reverse motor rotation. : Visually inspect cooling fans and clean away

Maintain at least 50mm (2 inches) of free clearance above and below the cooling fins.

Detects asymmetry in the three-phase power. Standards: Complies with IEC60947-1:2007 and IEC61000. Installation & Wiring Guide Installation is typically done on a standard DIN rail .

For further information and technical support, refer to the following resources:

Disconnect all power and follow lockout/tagout procedures before beginning installation. Control Circuit Wiring (Output): These terminals receive the

Restricts the maximum conduction angle. Turn clockwise to increase the peak output voltage. Use this if your load cannot handle full line voltage.

Keep ambient temperature between 0°C and 50°C. Humidity: Maintain below 85% RH without condensation.

The power connections for the GMR-32B are straightforward. It samples the voltage directly from your three-phase lines, not the load current.

Sets the ramp-up time in seconds (0-100s).

Generally rated for environments between -10°C and +55°C. Dimensions: Approximately Key Operational Features
