2.6.1 De-initialization of a System
Systems, which are powered-up for the first time, are
de-initialized. All LEDs of the de-initialized units
illuminate. In case some of the units are not in this
state, de-initialize these units or de-initialize the
system. See chapter 11 of the DCN Installation and
Operating Manual for how to de-initialize a system.
2.6.2 De-Initialization of Individual Voting Units
To de-initialize an individual unit, press the de-
init/init switch shortly (see Figure 2.13). All LEDs of
the de-initialized unit illuminate. To de-initialize and
initialize an individual unit at the same time, keep the
de-init/init switch pressed for a longer time.
Figure 2.13 De-Initialization LBB 4141/xx Voting Unit
2.6.3 Initialization of Individual Voting Units
To initialize an individual unit, press the button in
the middle of the voting unit (see Figure 2.14 and
Figure 2.15) or the de-init/init switch (see Figure
2.13). The units LEDs go out. Once the unit is
recognized in the system, the unit active indicator
illuminates. Repeat this procedure for all active units
installed in the system one by one.
i Note
Initialize the units one by one (and not
simultaneously) in order to eliminate address
conflicts.

2.6.4 Replacing a Voting Unit
Press the de-init/init (see Figure 2.13) switch while
connecting a replacement unit. The unit will be de-
initialized and initialized during connection. Once
the unit is recognized in the system, the unit active
indicator illuminates.
2.6.5 Re-installing a Temporary System
The units hold their addresses when the units are
disconnected. It is not necessary to de-initialize the
system, in case the same units are reconnected after
being stored. In case the units have been used in
another system in the meantime, follow the
procedures described in order to de-initialize the
system and initialize the units.
i Note
In case the temporary system is a Multi CCU
system, reconnect the units to the same CCU
as during initialization in order to eliminate
address conflicts or de-initialize the system.
2.7 Commissioning
To check whether a system with LBB 4141/xx voting
units works properly:
1. Start a voting (see paragraph 2.8.6)
2. Register presence and vote yes on all units (see
paragraph 2.8.6). See paragraph 2.9 in case a
voting unit is not working properly.
3. Check the voting results. If the voting results are
incorrect: determine which voting unit causes the
wrong results. Correct the position of the voting
button order jumper (see paragraph 2.3).
