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.
For more information about DIP settings details, see chapter DIP Switch settings in circuit board (page
24)
4.4
Control unit
The monitoring function of the central battery unit can operate using three different operating principles:
addressable monitoring, circuit monitoring or a combination of both. This is selected with the DIP switch
4.
Addressable monitoring and circuit monitoring can be set for different circuit boards within the same
unit: 8 circuits on addressable monitoring, 8 circuits on circuit monitoring, etc.
In addressable monitoring of the luminaires, each luminaire has its own unique address. There can be
1...16 luminaires in one circuit. On the display of the central battery unit the luminaires are displayed
with two numbers followed by the letter L
(for example “01L”). The central battery unit checks the
operation and indicates the result for each luminaire separately.
The circuit monitoring measures the current of a circuit in battery mode. The changes in the current are
used to determine possible faults in the circuit. The number of luminaires in a circuit is not limited, but
the input power of a circuit cannot exceed 250
VA or 1,6 A. Note that circuit monitoring doesn’t give
luminaire-specific information. The limit value of the error alarm can be changed in the settings, (1-31) =
+/- 10.. 310 mA. The factory settings are 16 = +/- 160 mA.
NOTE: If circuit monitoring current limits are changed in a configured centre, the unit goes into a non-
configured state and must be re-configured.
