What to do if programmable scheme logic error due to excessive execution time on Schneider Electric Protection Device?
If you encounter a programmable scheme logic error due to excessive execution time, restore default settings by performing a power up with the specified keys depressed.
What to do if Schneider Electric Protection Device relay settings are corrupted?
If your relay settings are corrupted, restore defaults to allow the power-up to be completed.
What to do if opto-isolated inputs fail on Schneider Electric Protection Device?
If the opto-isolated input state is not being correctly read by the relay the applied signal should be tested. Verify the connections to the opto-isolated input using the correct wiring diagram.
