Gmr-32b Phase - Controller Manual

380VAC (nominal, with variants for 440/460V) Contact Capacity: 250VAC / 6A or 30VDC / 3A Conventional Heating Current: 8A Power Consumption: ≤ 10VA Ambient Temperature: -10°C to +55°C

Three precision potentiometers reside on the face of the GMR-32B to fine-tune system response limits:

Before installing the GMR-32B, ensure that your system architecture aligns with the electrical limits of the controller. Electrical and Signal Limits

Adjust the trimmer until the desired peak output voltage is achieved. 6. Diagnostic LEDs and Troubleshooting gmr-32b phase controller manual

Ensuring correct rotation and voltage stability.

The is a sophisticated yet user-friendly device that acts as the sentinel for your critical three-phase equipment. By providing precise, time-delayed protection against the most common and damaging power quality issues—phase loss, reverse phase, voltage imbalance, and over/undervoltage—it prevents costly downtime and repairs. We hope this manual provides you with the knowledge to install, configure, and troubleshoot your GMR-32B successfully. For further help, refer to the manufacturer's official datasheet or contact your supplier.

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

Once powered, check the status LEDs. A stable indicator usually means correct operation, while specific flashing patterns indicate faults like phase reversal or imbalance. Visual Reference

This device monitors the three-phase power supply for four critical fault conditions: Phase Sequence (Rotation): Ensures the motor rotates in the correct direction. Phase Loss (Failure): Detects if one of the three phases is missing. Overvoltage: Protects against surges that could burn out motor windings. Undervoltage: not the load current. Once powered

Do you need help or a wiring diagram for a particular motor type?

for a specific application, such as an air compressor or water pump?

Once the GMR-32B phase controller is installed and configured, follow these operating instructions:

To configure the controller, access the parameter menu (usually via the "Set" or "Prog" button).

Mount the GMR-32B vertically on a standard 35mm DIN rail or direct-mount to a backplate using the integrated chassis screw holes.
