Important Notice: DO NOT PAY ADVANCE
Many manufacturers offer newer equivalents if the GMR-32B is discontinued. Ask for a cross-reference guide.
Must be connected to the corresponding phase lines driving the SCRs to ensure correct zero-crossing synchronization.
Wire a 10k Ohm potentiometer for manual dial control.
The manual organizes settings into three categories: Input, Output, and Protection.
: Indicates proper phase sequence and voltage within nominal thresholds. The internal control relay engages.
Standard connections for R, Y, and B (or L1, L2, L3) phases.
Disclaimer: This article is a detailed guide based on typical features of phase controllers resembling the GMR-32B model. Actual specifications, terminal assignments, and programming steps may vary by manufacturer and revision. Always use the original manual provided with your device.
Two normally open (NO) and two normally closed (NC) electrically separate contacts
The device utilizes a "Common" and "NO" (Normally Open) point for control wiring; if the power supply is correct, the relay completes the circuit to allow the motor contactor to operate. Wiring Summary
