- Check heating or cooling circuit
- Check sensor and replace
it, if necessary
- Check controller and
switching device

3.5.2 Error-Status (Self-tuning)
(error status 3 - 9 only with error AdA.H / AdA.C ):
Err-Status Description Behaviour
1
Stored error Delete the entry after acknowledgment
2
Existing error Change to error status 1 after error removal
3
Faulty control action Re-configure controller (inverse i direct)
4
No response of
process variable The control loop is perhaps not closed: check sensor,
connections and process
5
Low reversal point Let process cool down and start new adaptation attempt
6
Danger of exceeded
set-point (parameter
determined) If necessary, increase (inverse) or reduce (direct) set-
point
7
Output step change too
small Let process cool down and start new adaptation attempt
8
Set-point reserve too
small Increase set-point (invers), reduce (direkt)
9
Impulse tuning failed The control loop is perhaps not closed: check sensor,
connections and process
