10.2 Operating status display
As soon as a channel’s relay is picked up, the
corresponding channel LED lights up continuously.
Once the actuator has been configured via the central
control unit or a programming tool, the device LED
will indicate other device states in addition to those
already described.
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 during this process, this
is indicated by all the channel LEDs flashing
simultaneously. 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 transmitting 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
