Faults and Failure
RemedyDescription/causeIndication on display
●
Cool down, wait.
●
If the fault indication display persists after cool-
ing down:
-
Set selector switch to position Local con-
trol (LOCAL) and reset fault indication via
push button RESET.
-
Execute reset command via fieldbus.
●
Check fuses.
Motor protection tripped
Thermal fault
Check movement at actuator.No actuator reaction to operation commands within
the set reaction time.
Fault no reaction
Check device configuration:
Parameter Low limit Uspan M0832 must be less
than parameter Volt.level diff. potent. M0833.
Potentiometer is outside the permissible range.
Poti Out of Range
LPV: Lift Plug Valve function
The master actuator signals a fault
LPV not ready
1)
Check wiring.Loss of signal analogue input 1
Wrn input AIN 1
Check wiring.Loss of signal analogue input 2
Wrn input AIN 2
Check operation command control.
For 3-phase AC current mains, activate phase
monitoring (parameter Adapt rotary dir. M0171).
Check device configuration setting (parameter
Closing rotation M0176).
To delete the fault indication: Disconnect actuator
controls from the mains and perform reboot.
Contrary to the configured direction of rotation and
the active operation command, the motor turns into
the wrong direction.
Incorrect rotary direct.
Check DMF trip torque OP parameter.
Check DMF fault level parameter.
The torque in direction OPEN, measured at the
output drive shaft using the torque measurement
flange, is too high.
DMF fault OPEN
2)
Check DMF trip torque CL parameter.
Check DMF fault level parameter.
The torque in direction CLOSE, measured at the
output drive shaft using the torque measurement
flange, is too high.
DMF fault CLOSE

RemedyDescription/causeIndication on display
●
Check operation commands (reset/clear all op-
eration commands and send one operation
command only).
●
Set parameter Positioner to Function active.
●
Check setpoint.

Manual (Operation and setting).
Collective signal 13:
Possible causes:
●
Several operation commands (e.g. OPEN and
CLOSE simultaneously, or OPEN and SET-
POINT operation simultaneously)
●
A setpoint is present and the positioner is not
active
Wrong oper. cmd
Set selector switch to position REMOTE.Selector switch is not in position REMOTE.
Sel. sw. not REMOTE
Exit service software.Operation via service interface (Bluetooth) and
AUMA CDT service software.
Service active
Check setting and status of function <Local controls
enable>.
Actuator is in operation mode Disabled.
Disabled
●
Enable EMERGENCY stop switch.
●
Reset EMERGENCY stop state by means of
Reset command.
The EMERGENCY stop switch has been operated.
The motor control power supply (contactors or
thyristors) is disconnected.
