START-UP AND POWER LOSS
During the start-up of the device, the Prog./Test 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 refer to 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, all
shutter channels
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).
