Corrective measures
Replace the unit.
(Sensor backup is possible).
Reduce medium temperature.
Increase medium temperature.
Replace the unit.
Replace the unit.
(Sensor backup is possible).
Replace the unit.
(Sensor backup is possible).
First indication of drift detected,
prepare replacement of the unit.
Check if the parameter drW is
programmed correctly.
Drift exceeds alarm threshold,
replace the unit, temperature
measurement with reduced
accuracy possible.
Check if the parameter drA is
programmed correctly.
Check the supply voltage, provide
the indicated voltage.
Check the temperature of the
sensor top; ensure that the speci-
fied range is observed.
