Gmr-32b Phase Controller Manual

The is a digital three-phase power protection relay, also known as a phase controller, phase sequence protector, or voltage monitor. It continuously samples your incoming three-phase power supply. Only when the voltage level and phase sequence match its correct internal state will the controller’s output relay activate, allowing your equipment to run. If a problem arises, the device’s internal relay remains off, thus protecting your machinery.

Typical of the GMR series, this model employs digital circuit technology to monitor the incoming three-phase power supply. Unlike simple protection devices, the GMR-32B is engineered for high precision and reliability, ensuring it does not interfere with or get affected by the load's current size, its nature, or existing current imbalances.

The incoming voltage has exceeded or dropped below the safe threshold (e.g., ±15% for smart models). AliExpress wiring diagram for your motor type or information on where to a replacement unit? gmr-32b phase controller manual

Connect the outer wiper pins to +10V and COM , and the center adjustable pin to 0-10V . 5. Programming and Parameter Tuning

Cause: Downstream load current exceeded safe operating parameters.

If using flexible, multi-strand wire, crimp a needle-type terminal pin (ferrule) to ensure a stable electrical connection. Connect your primary power distribution phases ( If a problem arises, the device’s internal relay

The GMR-32B must be mounted vertically inside a well-ventilated control cabinet. Mounting Steps

Failure of one phase, which can cause severe motor damage.

The following specifications apply to the GMR-32B and GMR-32B Smart Series:
