The supply voltage has fallen below the
minimum voltage.
The actuator is moved to the safe
position. After approx. 5 seconds, the
positioner is automatically reset and
starts up again with the message
ERROR 10
. If a local communication
interface (LCI) is plugged in, the device
will enter the operating mode LCI
supply.
Check the power source and the wiring.
The position is outside the measuring
range. Possible reason is a malfunction
in the position sensor.
In c ontrol mode:
The actuator is moved to the safe
position.
On the configuration level:
The output is set to neutral until a button
is pressed. After approx. 5 seconds the

No access possible to the data in the
EEPROM.
The actuator is moved to the safe
position. After approx. 5 seconds, the
positioner is automatically reset.
Attempts are made to restore the data.
This compensates for intermittent errors
in the communication environment with
the EEPROM.
If there is still no access to the EEPROM
data after resetting the device, load the
factory settings. If the error still persists,
the device must be returned for repair to
the manufacturer.
