LED Meanings
| Meaning of signalling LEDs | ||
| LED | Colour | Meaning |
| TRIP | Red | The unit has the appropriate outputs in TRIP position and the unit is sensing a fault situation |
| Red flashing | The unit has the appropriate outputs in TRIP position, but the unit is sensing fault-free situation. Fault reset is possible. | |
| Nothing | The unit has no output in TRIP position | |
| U | Red flashing | Voltage of any phase is above threshold for 1st or 2nd stage overvoltage |
| Red | Voltage of any phase is under threshold for 1st or 2nd stage undervoltage | |
| Orange flashing | Voltage unbalance (amplitude) is indicated. | |
| If activated together with LED f and LOM, indicates incorrect phase rotation | ||
| Orange | Negative sequence overvoltage or Positive sequence undervoltage is indicated. | |
| If activated together with LED f and LOM, indicates incorrect polarity of one phase | ||
| Green | All voltages are in fault-free state | |
| Green flashing | 10 minutes floating average overvoltage is detected | |
| Nothing | Over/under voltage protections are not enabled by setpoint and no other voltage failure is sensed | |
| f | Red flashing | Frequency as sensed on terminals Ua is above threshold for 1st or 2nd stage overfrequency |
| Red | Frequency as sensed on terminals Ua is under threshold for 1st or 2nd stage underfrequency | |
| Orange flashing | Together with LED U and LOM, indicates incorrect phase rotation | |
| Orange | Together with LED U and LOM, indicates incorrect polarity of one phase | |
| Green | Frequency, rotation and phases polarity are in fault-free state | |
| Nothing | Over/under frequency is protections are not enabled by setpoint and no other indicated failure is sensed | |
| LOM | Red | Vector shift or ROCOF protection was indicated and Fault reset was not yet done |
| Orange flashing | Together with LED U and f, indicates incorrect phase rotation | |
| Orange | Together with LED U and f, indicates incorrect polarity of one phase | |
| Nothing | None of Vector shift or ROCOF failure is detected or neither Vector shift nor ROCOF protections are not enabled by setpoint and no other indicated failure is sensed | |
| Status | Red flashing | Indication of severe internal failure. Contact ComAp technical support! |
