Common faults
What usually fails on a unit like the LR2K0612
Protection relays have to trip when needed and stay quiet otherwise, so a repaired relay must be tested against its settings, not just powered up. Power supplies, input boards, displays and output contacts are the usual failure points.
Relay dead or rebooting
Failed internal power supply, often from age or a surge on the auxiliary supply.
Self-supervision or internal fault alarms
Faults in the processor board, memory or analog input stages.
Wrong measurement
Current or voltage inputs reading wrongly because of damaged input transformers or analog circuits.
Output contacts not operating
Burnt or welded output relay contacts, or failed driver circuits.
Display and keypad faults
Unreadable displays and dead keys, which make settings hard to check.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Record any self-supervision alarm and the event log.
- Check the auxiliary supply voltage.
- Keep a copy of the settings file.
Leave to a specialist
- Secondary injection testing after repair.
- Changing or uploading relay settings.
- Any work on CT and VT circuits: open CT secondaries are dangerous.
