The is an indispensable safety device in modern industrial setups, ensuring that three-phase loads are protected against fatal voltage and phase faults. By following the installation procedures in this guide, users can ensure robust protection for their motors and 3-phase equipment .
Use fast-acting fuses to protect the semiconductor switches. Installation and Mounting
Mount the unit vertically inside an IP54-rated industrial electrical enclosure. : Formulated to meet IEC60947-5-1 and GB14048
Check for blown high-speed semiconductor fuses. Verify all three phases are present. Gate trigger wires disconnected or SCR failed open.
Verify signal shielding. Ensure sync lines (L1/L2/L3) match the main SCR phase lines. Over-current or Phase Loss detected.
Proper physical placement prevents thermal runaway and electrical noise interference. Mounting Steps

The GMR-32B is a microprocessor-based digital instrument designed for three-phase electrical systems. Its primary function is to measure voltage, analyze phase sequence, and protect equipment against phase failure (loss of phase), phase asymmetry (unbalance), and reverse phase sequence. This report outlines the necessary setup parameters, operational logic, and troubleshooting procedures required for manual operation.
Complete Technical Guide and Manual for the GMR-32B Phase Controller
Check continuity of G and K wires to the SCRs; ensure they are not swapped. Electrical noise on control signal.
If the system fails to trip during a clear voltage event, turn off power and check for mechanical sticking or fused contacts inside the external motor contactor auxiliary blocks.
Connect to the incoming three-phase AC line voltage. This provides the phase synchronization reference for the microcontroller.
