Case of diagnosis
Warning
Alarm
Failure
Drift warning threshold [drW]
exceeded (factory setting: 0�2 °C)
●
Limit temperature internal elec-
tronics exceeded (+90°C)
●
Drift alarm threshold [drA] ex-
ceeded (factory setting: 0�5 °C)
●
Failure of one of the two sensor
elements (interruption / short
circuit)
●
Process value does not reach
the analogue start point [ASP] or
exceeds the analogue end point
[AEP] → 4.4 Analogue function
●
Supply voltage outside the oper-
ating range
●
Failure of both sensor elements
(interruption / short circuit)
Or
general electronics problems
(partial malfunction in the sensor
electronics)
●
Fault during parameter setting of
the IO-Link
●
Drift failure threshold [drF] >
drift alarm threshold [drA] + 3 K
●
