Gmr32b+phase+controller+manual+patched !link! Info

The patched manual clarifies that the device will NOT auto-reset if the phase unbalance persists beyond 10 seconds. This prevents contactor chatter. Chapter 3: Wiring the GMR32B – The Patched Diagram Follow this corrected wiring schematic. Failure to use the patched terminal mapping will result in the controller showing a "healthy" LED when phase reversal exists. Terminal Assignment (Patched Version) | Terminal No. | Function | Wire Color Guide | |--------------|----------|------------------| | 1 | R Phase Input (L1) | Brown | | 2 | Y Phase Input (L2) | Black | | 3 | B Phase Input (L3) | Grey | | 4 | Supply Neutral (N) – if used | Blue | | 5 | Relay Common (C) | White | | 6 | Relay Normally Open (NO) | Red (to contactor coil) | | 7 | Relay Normally Closed (NC) | Not used in most applications | | 8 | Auxiliary Alarm Common | Orange | | 9 | Auxiliary Alarm NO | Yellow (to PLC or buzzer) | Patched Warning: Original manuals swapped terminals 6 and 9. Follow the above. Standard Motor Protection Circuit [3-Phase Supply] ---> [MCCB/Fuse] ---> [GMR32B Terminals 1,2,3] | | (Terminal 6) v [Contactor Coil A1] | [Contactor Coil A2] ---> [Neutral/Return] When phases are correct and balanced, the internal relay energizes, allowing the contactor to close. Chapter 4: Configuration DIP Switches – The Patched Logic The GMR32B has a 4-position DIP switch bank. The original manual described Switch 2 as "Unbalance Enable/Disable". The patched manual reveals it actually controls Response Time Mode .

| Switch | Original Function | Patched (Correct) Function | |--------|-------------------|----------------------------| | SW1 | ON=380V, OFF=415V | ON=400-480V, OFF=200-400V | | SW2 | Unbalance ON/OFF | | | SW3 | Auto reset | Auto/Manual reset (ON=Auto, OFF=Manual) | | SW4 | Phase sequence (ON=R-Y-B, OFF=any) | Phase sequence lock: ON=Strict R-Y-B, OFF=Any order allowed | gmr32b+phase+controller+manual+patched

The technician downloaded the patched manual and discovered that the "Fast Response Mode" (SW2=ON) was causing trips due to normal voltage fluctuations in the old wiring. Setting SW2 to OFF (patched recommendation) solved the issue immediately. The patched manual clarifies that the device will
