Function description
After switching on the bus, which also acts as a power supply, the device becomes fully functional after a very
short time needed for reinitialization. A delay is programmable for the device to become active on the bus in
order to avoid a bus traffic overload during the first moments of start-up of the whole network.
In case of a bus power failure (voltage lower than 19 V for 1 s or more), the device becomes unreactive: the
timing functions are not active, neither are the programmed group addresses.
As soon as the bus voltage is restored, the device will resume operation in its previous state (which is saved
on power fail), unless different initialization settings are programmed.
6.1. Offline operation
A fully unprogrammed device does not operate in standby mode. Yesnce the operation relies entirely on the
exchange of information through communication objects, there is no part of the device that can operate
independently from a KNX bus.
6.2. Online operation
In general the device works like a configurable digital sensor that is listening to own inputs or outputs of other
devices. On input events the device performs output functionality over KNX bus like sending values or
controlling external devices like KNX actuators.
