Self-test error
If an error occurs, the "DEVICE" LED lights up red. The error can only be acknowledged by
switching the device off and then on again. If the error is still present, the self-test will return
an error again when the device is switched on. In this case, the motor starter must be
replaced.

Specific device components are monitored continuously (internally) by the motor starter and
the results signaled with the self-test messages. The message "Self-test error" can also
appear in the case of an internal monitoring fault without the self-test having been activated.
