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.

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. 
 
 
   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. 
 
 
   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).
