Behavior after the return of the mains voltage
7 Behavior after the return
of the mains voltage
Once the network voltage has been restored (e. g. after a power fail-
ure) the device restarts and performs a self-test. This process lasts ap-
proximately 2 seconds. The LED flashes in orange and green during this
process. If a fault is found, the LED flashes (see „Displays" page 29).
If a fault is present, the process is repeated and the device only starts to
perform its actual function after the elimination of the fault. If the test
has been performed without faults, or after the elimination of the fault,
the device sends a status information.
