The supply voltage to the
Temperature Sensing section in the
Temperature module is low.
Resolution:
Check that the power supply and loop
resistance are within specification. If
possible, try to increase the voltage
level of the supply. If supply voltage
and loop resistance are adequate and
the problem persists, replace the
Temperature module.
