11 Response to power recovery
When the operating voltage is switched on (recovery of
mains voltage), the actuator checks its components. If
an error is detected, all channel LEDs will flash. This is
repeated continuously and the device does not perform
its function. If the test is completed without errors, the
actuator transmits a wireless telegram containing its
status information. To prevent all actuators from trans-
mitting at the same time when power is recovered (after
a mains power failure or a disconnection, for example),
there is a random delay before the actuator transmits.
During this time, the channel LEDs flash (as in teach-in
mode). If the delay is very short, this flashing may be
almost imperceptible.
