11 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 repeated
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.
