Faults and Failure
Remedy
Description/cause
Indication 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
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
Deviation MA/SA [%]
parameter.
Synchronous link function: Actual position values
of master actuator and slave actuator are not syn-
chronous (excessive deviation).
Syn. link deviation
Check
Deviation MA/SA [%]
parameter.
Synchronous link function: Slave actuator is not
ready.
Syn. link NotReady
Check wiring.
Synchronous link function: Signal loss of actual po-
sition value from master actuator or slave actuator.
Syn. link wire break SA
Motor protection: Fault within converter
Rectifier fault
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
1)
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
1)
For actuators equipped with torque measurement flange (DMF)

eration commands and send one operation
command only).

to display a list of indi-
vidual indications.
For a description of the individual signals, refer to
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.
EMCY stop active
