4. Description of operations
4.1 Purpose of the central battery unit
In a normal situation the purpose of the central battery unit is to

monitor the mains voltage

maintain the battery charge level

supply power for the maintained emergency luminaires
During a mains failure the central battery unit will supply voltage to the maintained and the non-
maintained emergency lighting circuits from the batteries.
The central battery unit also includes functions for testing and monitoring the condition of the luminaires
and the batteries.
4.2 Circuit outputs
Circuit output connections can be selected as maintained or non-maintained mode from circuit board.
For more information, see chapter
5.2 System installation .
4.3 Circuit board settings
In the central battery unit there are 1-3 circuit boards. Every board has eight output circuits. On circuit
boards there is a DIP-switch selector that defines the characteristic of the board. The functions of the
DIP-switches are:

DIPs 1-3 give the board its internal address

DIP 4 defines whether the board uses addressable central monitoring or circuit monitoring. Set
to OFF position defines board to use addressable central monitoring.

DIPs 5 and 6 are used when the parallel connection of the output circuits is used.
For information on the circuit boards
’ DIP settings details, see chapter
5.2.3 DIP switch settings in circuit
boards.
4.4 Parallel connection of output circuits
Output circuits can be connected parallel to get a bigger circuit output power.

Factory settings give 8x 350 W output power

Two circuits connected parallel gives 4x 700 W output power

Four circuits connected parallel gives 2x 1400 W output power
For more information on making a parallel connection between output circuits, see chapter 5.2.2 Circuit
wiring in parallel connection.
NOTE: When parallel connections are used, the output circuits
’ connectors running the circuit numbers
may change. The circuit numbers must be changed to correspond with the amount of the connected
circuits.
