In circuit monitoring, the central battery unit will wait for a few minutes and let the luminaires warm up
before measuring the current in each circuit. The first luminaire test is automatically a configuration. The
configuration cannot be interrupted. The results of later tests are compared with the configuration data.
Once the Luminaire test and External fault LEDs go off, the central battery unit is configured and has
returned to normal mode. In normal mode, the display will show the information of each circuit one at a
time. The information of each circuit will be shown for four seconds.
You can browse the circuit information with the BROWSE button.
After the central battery unit has configured itself, it will return to the normal mode .
6. Maintenance
The condition of the emergency lighting system must be ensured by regular maintenance according to
the laws and regulations of local authorities.
In addition to the checks and inspections there is no regular maintenance required for the central
battery unit, other than changing the batteries when the specified emergency mode duration is no
longer achieved.
The luminaires need to have their light sources replaced once they have reached the end of their
lifetime.
Only a qualified electrician may perform such maintenance operations which require opening of
the casing of the central battery unit or the battery container.
6.1 Replacing the batteries
To replace the batteries,
1. Open the hatch of coupling space.
2. Remove the battery fuses F2 and F3 (see picture from chapter 5.2.1 Parts layout ).
Mains operation and Internal fault LEDs will be lit.
3. Turn the S1 main switch and distribution fuse F1 to '0' position (see picture from chapter 5.2.1 Parts
layout ).
The display LEDs go off = the central battery unit is de-energized.
4. Remove the cover from the battery case(s).
5. Disconnect the cables coming from the central battery unit from the batteries.
Remove the minus cable first.
6. Remove the battery interconnection cables.
7. Pull the temperature sensor aside.
8. Lift off the batteries and replace them with new ones.
9. Place the batteries' temperature sensor between the batteries.
NOTE! Misplacing the temperature sensor may damage the batteries!
10. Connect the battery cables (pay attention to polarity and insulation distances).
