Description/cause
Collective signal 06:
Possible cause:
Configuration setting is incorrect.
The device can still be operated with restric-
tions.
Collective signal 15:
Device warnings
The device can still be operated with restric-
tions.
The external 24 V DC voltage supply of the
controls has exceeded the power supply limits.
Warning on time max. running time/h ex-
ceeded
Warning on time max. number of motor starts
(starts) exceeded
The failure behaviour is active since all re-
quired setpoints and actual values are incor-
rect.
Warning: Loss of signal analogue input 1
Warning: Loss of signal analogue input 2
Warning: Loss of signal of actuator setpoint
position
Possible causes:
Input signal for setpoint = 0 (signal loss)
The set time (parameter Perm.op. time,
manual M0570) has been exceeded. The
preset operating time is exceeded for a com-
plete travel from end position OPEN to end
position CLOSED.
Temperature within controls housing too high
Temperature within motor winding too high
Temperature within actuator gear 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
successfully completed.
Partial Valve Stroke Test (PVST) was aborted
or could not be started.
No actuator reaction to operation commands
within the set reaction time.
Optical receiving signal (channel 1) incorrect
(no or insufficient Rx receive level) or RS-485
format error (incorrect bit(s))
Warning: FO cable system reserve reached
(critical or permissible Rx receive level)
