7.5 Signalling
7.5.1 Signalling during the Switch-On Process
After the FSA-PLUS Switcher has been switched on, a test routine is carried out
with the following signalling, independent of the configuration which has been set:
During the first 3 seconds, all the LEDs light up for a LED test (LED Test)
During the following 3 seconds, all perfect recognised moving cards (MOC) are
displayed. Each MOC is assigned to a LED as follows:
MOC 1

ON
OFF
1
4
MOC 2
MOC 3
MOC 4
MOC 5

The status of ”no MOC recognised” leads to a fatal error. This will be signalled by
the flashing of all the LEDs.
This is followed by the stable signalling of operational status
The test routine can be repeated at random without this leading to any variation in
the switching status of the FSA-PLUS Switcher.
There the FSA-PLUS Switcher is turned off and then turned on again after a wait-
ing time of approx. 5 seconds. The signalling occurs once again as described
above.
In double mode, after the central FSA-PLUS Switcher has been switched on, a
comparison is made of the number of recognised moving cards (MOC) of both
FSA-PLUS Switcher. In the event of an unequal number of recognised moving
cards, an alarm is activated.
