Description/cause
Collective signal 08:
Indication according to NAMUR recommendation
NE 107
The actuator is being worked on; output signals are
temporarily invalid.
Collective signal 09:
Indication according to NAMUR recommendation
NE 107
Recommendation to perform maintenance.
Collective signal 10:
Indication according to NAMUR recommendation
NE 107
Actuator function failure, output signals are invalid
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.
