Operator’s Manual
REM 610
1)
Temperature protection stages are out of operation.
Trip-circuit
supervision 2 • Error in trip circuit
- Check the trip circuit for broken conductors and correct.
- Warning will not be displayed if trip-circuit supervision (TCS)
has been disabled
Power supply
module
temperature high 4 • Temperature inside relay is too high
- Check that ambient temperature is within service temperature
range
Communication
module faulty or
missing 8 • Communication module faulty or not installed
- Check that plug-in unit is properly attached to relay case
- Check that communication module is installed
- Warning will not be displayed if rear communication module
has been disabled
- In case only this warning is active, it will be displayed in text
format (Comm.card faulty)
RTD module
faulty 16 Three possible causes:
1) Storing in non-volatile memory has not been successful, which
means that old settings will be taken into use after power up
2) Self calibration has failed
3) Offset voltage out of range
- If warning is not cleared after a power reset, the relay may
require service
