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.

2.6.2De-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.

iNote

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.

iNote

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).
