connection by means of the on-board screws.
Inputs (4)
: input ports for the insertion of the stripped cables of external
elements such as switches / motion detectors / temperature probes, etc. One
of the two cables of each element needs to be connected to one of the slots
labelled “1” to “4”, while the other cable should be connected to the slot
labelled as “C”. Note that all the external input devices share the “C” slot for
one of the two cables. Please secure the connection by means of the on-
board screws.

START-UP AND POWER LOSS
During the start-up of the device, the Test/Prog. LED will blink in blue colour for a few
seconds before the device is ready. External orders will not be executed during this
time, but afterwards.
Depending on the configuration, some specific actions will also be performed during
the start-up. For example, the integrator can set whether the output channels should
switch to a particular state and whether the device should send certain objects to the
bus after the power recovery. Please consult the next sections of this document for
further details.
On the other hand, when a bus power failure takes place, the device will interrupt any
pending actions, and will save its state so it can be recovered once the power supply is
restored. For safety reasons, the
shutter channel
will be stopped (i.e., the relays will
open) if a power loss takes place, while the individual outputs will switch to the specific
state configured in ETS (if any).
