Check 24 V DC voltage supply. The external 24 V DC voltage supply of the controls
has exceeded the power supply limits. 24 V DC external
●
Check modulating behaviour of actuator.
●
Check parameter Perm. run time M0356 , re-set
if required.
Warning on time max. running time/h exceeded Wrn op.mode run time
●
Check modulating behaviour of actuator.
●
Check parameter Permissible starts M0357 , re-
set if required.
Warning on time max. number of motor starts
(starts) exceeded Wrn op.mode starts
Verify signals:
●
Setpoint E1
●
Actual value E2
●
Actual process value E4
●
Check connection to master.
●
Check (clear) status of master.
The failure behaviour is active since all required
setpoints and actual values are incorrect. Failure behav. active
Check wiring. Warning: Loss of signal analogue input 1 Wrn input AIN 1
Check wiring. Warning: Loss of signal analogue input 2 Wrn input AIN 2
Check setpoint signal. Warning: Loss of signal setpoint position
Possible causes:
For an adjusted setpoint range of e.g. 4 – 20 mA,
the input signal is 0 (signal loss).
For a setpoint range of 0 – 20 mA , monitoring is
not possible. Wrn setpoint position
The warning indications are automatically cleared
once a new operation command is executed.
●
Check valve.
●
Check parameter Perm.op. time, manual
M0570 .
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.
Op. time warning
Measure/reduce ambient temperature. Temperature within controls housing too high. Wrn controls temp.
Set time. Real time clock has not yet been set. Time not set
Replace button cell. Voltage of the RTC button cell is too low. RTC voltage
Check actuator (PVST settings). Partial Valve Stroke Test (PVST) could not be suc-
cessfully completed. PVST fault
Perform RESET or restart PVST. Partial Valve Stroke Test (PVST) was aborted or
could not be started. PVST abort
●
Check movement at actuator.
●
Check parameter
Reaction time M0634
.
No actuator reaction to operation commands within
the set reaction time. Wrn no reaction
Check parameter Wrn torque OPEN M0768 , re-set
if required.
Limit value for torque warning in direction OPEN
exceeded. Torque wrn OPEN
Check parameter
Wrn torque CLOSE M0769
, re-
set if required.
Limit value for torque warning in direction CLOSE
exceeded. Torque wrn CLOSE
