SAEx 16.2-UW / SAREx 07.2-UW
Description/cause
Motor protection tripped
No actuator reaction to operation commands within
the set reaction time.
Potentiometer is outside the permissible range.
LPV: Lift Plug Valve function
The master actuator signals a fault
Loss of signal analogue input 1
Loss of signal analogue input 2
Contrary to the configured direction of rotation and
the active operation command, the motor turns into
the wrong direction.
The torque in direction OPEN, measured at the
output drive shaft using the torque measurement
flange, is too high.
The torque in direction CLOSE, measured at the
output drive shaft using the torque measurement
flange, is too high.
Collective signal 25:
Description/cause
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
Selector switch is not in position REMOTE.
Operation via service interface (Bluetooth) and
AUMA CDT service software.
Actuator is in operation mode Disabled.
The EMERGENCY stop switch has been operated.
The motor control power supply (contactors or
thyristors) is disconnected.

Remedy
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.
Check movement at actuator.
Check device configuration:
Parameter Low limit Uspan M0832 must be less
than parameter Volt.level diff. potent. M0833.
Check wiring.
Check wiring.
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.
Check DMF trip torque OP parameter.
Check DMF fault level parameter.
Check DMF trip torque CL parameter.
Check DMF fault level parameter.
Press push button
vidual indications.
For a description of the individual signals, refer to
Manual (Operation and setting).
Remedy
Check operation commands (reset/clear all op-
eration commands and send one operation
command only).
Set parameter Positioner to Function active.
Check setpoint.
Press push button
vidual indications.
For a description of the individual signals, refer to
Manual (Operation and setting).
Set selector switch to position REMOTE.
Exit service software.
Check setting and status of function <Local controls
enable>.
Enable EMERGENCY stop switch.
Reset EMERGENCY stop state by means of
Reset command.
