Behavior after power restoration

After switching the operating voltage on (mains voltage returned),
the actuator checks the respective components. If an error is
detected during this test, it is indicated by a flashing LED. This is re-
peated continually and the device starts to work with the respective
functionality.
If the test runs without any errors, the actuator sends a radio
telegram with the respective status information. The actuator waits
a random delay time before sending so that all actuators are not
sending at the same time when the power returns (after a power
outage or shut-down). During this time, the device LED flashes (like
in teach mode). If the delay time is short, the flashing may not even
be noticeable.
