Phase Controller Manual — Gmr-32b

Cause: The controller detects a missing or highly unstable incoming AC phase.

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

Check continuity of G and K wires to the SCRs; ensure they are not swapped. Electrical noise on control signal. gmr-32b phase controller manual

Use insulated copper wire with a cross-sectional area of . For secure connections:

One phase is missing or there is a significant voltage difference between phases. Over/Undervoltage: Cause: The controller detects a missing or highly

System power indicator. Lights up when the internal control electronics receive sufficient auxiliary voltage.

Disconnect all power sources before attempting installation, wiring, or maintenance. Check continuity of G and K wires to

4-20mA, 0-10V DC, 1-5V DC, or 10kΩ Potentiometer Output Phase Control Range: 0 to 180 electrical degrees

– Use:

There are two ways to physically mount the device:

Significant differences in voltage between the phases create excessive heat in motor windings. The device calculates this asymmetry and safely disengages the system. Installation & Wiring Guide
