Faults and Failure
RemedyDescription/causeIndication on display
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.
Motor protection: Fault within converter
Rectifier fault

Not ready REMOTE and Function check (collective signal 04)
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.

●
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
●
Detect cause for EMERGENCY signal.
●
Verify failure source.
●
Apply +24 V DC at EMERGENCY input.
Operation mode EMERGENCY is active (EMER-
GENCY signal was sent).
0 V are applied at the EMERGENCY input.

Check I/O interface.The actuator is controlled via the I/O interface (par-
allel).

Release push button STOP.A local STOP is active.
Push button STOP of local controls is operated.

Automatic reset fuse as short-circuit protection for external 24 V DC supply for
customer (refer to wiring diagram)
12.3.2. Motor protection (thermal monitoring)
In order to protect against overheating and impermissibly high surface temperatures
at the actuator, PTC thermistors or thermoswitches are embedded in the motor
winding. Motor protection trips as soon as the max. permissible winding temperature
has been reached.
