Description/cause
Collective signal 06:
Possible cause:
Configuration setting is incorrect.
The device can still be operated with restrictions.
Collective signal 15:
Device warnings
The device can still be operated with restrictions.
The external 24 V DC voltage supply of the controls
has exceeded the power supply limits.
Warning on time max. running time/h exceeded
Warning on time max. number of motor starts
(starts) exceeded
The failure behaviour is active since all required
setpoints and actual values are incorrect.
Warning: Loss of signal analogue input 1
Warning: Loss of signal analogue input 2
Warning: Loss of signal setpoint position
Possible causes:
For an adjusted setpoint range of e.g. 4
the input signal is 0 (signal loss).
For a setpoint range of 0 20 mA , monitoring is
not possible.
The set time (parameter Perm.op. time, manual
M0570) has been exceeded. The preset operating
time is exceeded for a complete travel from end
position OPEN to end position CLOSED.
Temperature within controls housing too high.
Real time clock has not yet been set.
Voltage of the RTC button cell is too low.
Partial Valve Stroke Test (PVST) could not be suc-
cessfully completed.
Partial Valve Stroke Test (PVST) was aborted or
could not be started.
No actuator reaction to operation commands within
the set reaction time.
Limit value for torque warning in direction OPEN
exceeded.
Limit value for torque warning in direction CLOSE
exceeded.

Replace button cell.
Check actuator (PVST settings).
Perform RESET or restart PVST.
Check movement at actuator.
Check parameter Reaction time M0634.
Check parameter Wrn torque OPEN M0768, re-set
if required.
Check parameter Wrn torque CLOSE M0769, re-
set if required.
