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 .
12 Maintenance and cleaning
The product does not require any maintenance . Enlist
the help of an expert to carry out any repairs .
Disconnect the device from the power supply system
before commencing cleaning . Use a dry linen cloth to
clean the device . If the device is particularly dirty, you
can slightly dampen the cloth to clean it . Do not use any
detergents containing solvents for cleaning purposes .
Make sure that no moisture will ingress into the housing .
