Shuts down the circuit if any phase-to-phase voltage drops below 60% of the rated input.

Swap any two input wires; if the red LED activates, the sensor is working correctly. gmr32b+phase+controller+manual+patched

Protects against overvoltage and undervoltage, with adjustable thresholds typically ranging from -30% to +30% of the rated input. Shuts down the circuit if any phase-to-phase voltage

Power the system and check the LED status . A green light indicates a correct sequence, while red signifies an error. Technical Specifications Specification Rated Voltage 380V AC (Standard) / Wide range options up to 500V Input Range Power the system and check the LED status

Connect the three-phase lines (L1, L2, L3) to terminals 1, 2, and 3 respectively.

A common "patch" in updated manuals is the clarification of , which can be toggled between 1s and 5s via internal DIP switches to avoid nuisance tripping during initial power-up. If the controller fails to operate:

Connect relay output terminals (4 and 5) to the control circuit of your contactor or Variable Frequency Drive (VFD).
