EOCR g-F — Ground Fault
Trip — immediate stop
CAUSE
Why does it occur?
- Ground fault
- Ground/leakage current exceeded the set sensitivity (30mA~3A) for the set time (0.05~5.0s, ZCT type)
REMEDY · Step by step
How to fix it?
Check insulation and wiring for ground faults; verify the ground-fault sensitivity/time settings.
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
