Saved alarms (Err-LED is lit) can be acknowledged and deleted with the digital
input di1/2/3 or the Ò-key.
Configuration, see page 27:
ConF / LOGI / Err.r
g
If an alarm is still valid that means the cause of the alarm is not removed so far
(Err-LED blinks), then other saved alarms can not be acknowledged and deleted.

(LOOP)
- Input signal defective or not
connected correctly
- Output not connected
correctly
- Check heating or cooling circuit
- Check sensor and replace it, if necessary
- Check controller and switching device

Error status Description Behaviour
0 No error
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 Increase ( ADA.H) max. output limiting Y.Hi or
decrease ( ADA.C) min. output limiting Y.Lo
6 Danger of exceeded set-point
(parameter determined)
If necessary, increase (inverse) or reduce (direct) set-point
7 Output step change too small
(dy > 5%)
Increase ( ADA.H) max. output limiting Y.Hi or reduce
( ADA.C) min. output limiting Y.Lo
8 Set-point reserve too small Increase set-point (invers), reduce set-point (direct)
or increase set-point range
