Manual Portable - Gmr-32b Phase Controller

Apply thermal grease uniformly to the backplate before securing it to the enclosure backpanel or heatsink. 3. Wiring Diagrams and Terminal Configurations

Connect the relay contact terminals in series with the magnetic contactor coil of your motor or load. Normally Open (NO): Closes when power is normal.

Before diving into the manual, it's essential to familiarize yourself with the key features of the GMR-32B phase controller:

A: Yes, but only for soft-start and low-duty applications. For precise speed control, a variable frequency drive is better. Phase-angle control of motors can cause overheating.

If the phase sequence (R, S, T) is wired incorrectly during setup, the relay prevents the system from starting. This is vital for equipment like pumps or compressors where running backward causes immediate mechanical destruction. 2. Dynamic and Static Phase Loss Protection

Follow these steps to mount, wire, and safely power up the GMR-32B for the first time. Step 1: Mechanical Mounting Apply thermal grease uniformly to the backplate before

Safety Warning: Disconnect all power sources before working on terminal connections. Follow local electrical codes (e.g., NEC) for wire sizing. Power Terminal Strip (High Voltage Block)

Position the unit inside an enclosed electrical distribution box or power distribution cabinet away from direct water contact or corrosive environments.

This comprehensive manual provides engineering specifications, installation workflows, configuration parameters, and diagnostic protocols for the GMR-32B module. 1. Technical Specifications Normally Open (NO): Closes when power is normal

Prevents damage caused by low voltage which increases heat and current draw. 3. Basic Wiring & Operation

Connect the positive control wire to Terminal 2 and the ground wire to Terminal 3.

Connect to the incoming three-phase AC line voltage. This provides the phase synchronization reference for the microcontroller.
