6.1 SP7-20 Error codes
Error code Possible cause Impact Troubleshooting
ERROR 10 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.)
- Check the power
source and the wiring.
ERROR 11 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.
ERROR 12 The position is outside the
measuring range. Possible
reason is a malfunction in
the position sensor.
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.
Check the mounting.
ERROR 13 Invalid input current.
This display indicates
when the setpoint signal is
overridden. The actuator is
moved to the safe position.
- Check the power
source and the wiring.
ERROR 20 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.
ERROR 21 Error while processing the
measured values, pointing
to an error in the working
data (RAM).
The actuator is moved to the safe
position. After approx. 5 seconds, the
positioner is automatically reset and the
RAM is reinitialised.
If the error persists
even after the
positioner has been
reset, the device will
need to be returned to
the manufacturer for
repair.
