) must be sampled from the line/power source side of the three-phase distribution system. Never install the sampling inputs on the output side of a Variable Frequency Drive (VFD) or Inverter! The pulse-width modulation (PWM) harmonics from a VFD will cause false trips, erratic LED behavior, and can permanently damage the internal monitoring circuitry of the relay.

Standard factory manuals often omit instructions for unlocking the extended registers or bypassing strict over-temperature trip points during emergency overrides. This patched manual details the specific jumper configurations and software hex edits required to safely optimize the unit beyond factory restrictions. 2. Hardware Installation and Wiring Architecture

| LED Pattern | Meaning | Original Recommendation | Patched Fix | |-------------|---------|--------------------------|--------------| | Solid Green | Normal, phases OK | No action | No action | | 1 Red Blink | Phase loss on R | Check L1 fuse | Also check internal solder joint R1 – known batch issue | | 2 Red Blinks | Phase loss on Y | Check L2 | Measure voltage between Y and N – should be >100V | | 3 Red Blinks | Phase loss on B | Check L3 | Also indicates high harmonic distortion >15% | | Fast Red Flashing | Phase reversal | Swap any two phases | Use SW4 to lock sequence after fixing | | Slow Red (every 5 sec) | Unbalance >8% | Reduce load | Patched: Adjust VR2 potentiometer clockwise to increase tolerance | | 2 Green / 1 Red | Internal EEPROM error | Replace unit | Patched: Perform "factory reset" – short terminals 5-8 for 10 seconds | October 2023 | Category: Industrial Automation / Motor

If anyone has access to the GMR32B phase controller manual, especially one that includes patched updates, I would greatly appreciate it if you could share it or point me towards a resource.
