Error codes

Error code Possible cause
The supply voltage was interrupted for at
least 20 ms.
(This error is displayed after resetting the
device to indicate the reason for the reset.)
The supply voltage has fallen below the
minimum voltage.
The position is outside the measuring
range. Possible reason is a malfunction in
the position sensor.
Invalid input current.
This display indicates when the setpoint
signal is overridden. The actuator is moved
to the safe position.
No access possible to the data in the
EEPROM.
Impact
—
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.
In control 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 positioner is
automatically reset in control mode and
on the configuration level.
—
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.
Troubleshooting the Instrument
Check the power source and the wiring.
Check the power source and the wiring.
Check the mounting.
Check the power source and the wiring.
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.
