Weighting Description
factor
1 Description Battery voltage level low
Battery should be replaced
*
Warning will not be displayed if non-volatile
*
memory settings have been set to 0
In case only this warning is active, it will be
*
displayed in text format (BATTERY LOW)
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
4 Temperature inside relay is too high
Check that ambient temperature is within
*
service temperature range
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)
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
32 At least one sensor (RTD1...6) is outside
measurement range
Check that sensors are not broken
*
64 Circuit is open or shorted
Check wiring of sensor
*
Check that sensor is not broken
*
128 Circuit is open or shorted
Check wiring of sensor
*
Check that sensor is not broken
