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
