During the charging process the leading
flashing LED indicates the amount of capacity
charged so far. The LED's for the capacity
already charged indicate continuously (fig. 3).
The charging process is complete when all
five green LED's are illuminated and none is
flashing. The LED display takes into account
the decline in the capacity of the battery: i.e., if
the indication does not go beyond the 3rd green
LED even after an extended charging period,
the available capacity is between 40 and 60%.
This indication is updated again on each emer -
gency lighting operation until the battery is shut
down by the deep discharge protection for the
battery.
The reduction in the battery capacity due to
self-discharge in normal operation is automati-
cally recharged controlled by the microproces-
sor.
Emergency lighting operation
The duration of emergency lighting can be set
to either 1.5 or 3 hours, see eLLK 92/ eLLS 08
NIB operating instructions (300 8000 1455).
Emergency lighting operation is automatically
initiated by the FT+TBT, by mains failure, or
manually by shutting down the mains supply.
During this process the emergency luminaire
marked in red is switched to battery operation.

5 Commissioning
Prior to initial commissioning the correct
function, the correct working order and the
installation of the emergency luminaire in
agreement with these supplementary
instructions and the eLLK 92/ eLLS 08 NIB
operating instructions (300 8000 1455), as well
other applicable stipulations are to be checked!
Note: to ensure the maximum possible battery
service life, full charging must be performed
after 6 months storage.
After replacing the battery it is then to be fitted
to the connector pins and introduced into the
connector in the battery box. The voltage at the
connector pins is only present when the
contacts are made (figure 4).

The battery box is to be closed again by
tightening the two fixing screws. Take care to
tighten these two screws with the test torque
of 2.0 Nm! Applying too high a torque might
easily damage the plastic housing for the
battery.
Battery charging starts when the power is
switched on. On the connection of a new
battery the indication of the charge state may
be delayed by a few minutes. After a charging
period of 14 hours the battery will have
reached approx. 90% of its rated capacity.
To enable the full battery capacity to be reached
after a prolonged storage time, it is recommen-
ded to carry out at least 3 charging/discharging
cycles.
6 Fault indicator
Functions of the red malfunction LED
The red LED flashes when:
– During an FT a faulty supply unit (VE) or a
faulty fluorescent tube is detected;
orr
– The minimum operating time during the
automatic partial service life test is not
achieved (< 30 min.).

remains until the fault is rectified.

The red LED indicates continuously if:

The following tests should be performed:
– Testing of the fluorescent tube and replace-
ment of the faulty tube, if necessary. Note
that low ambient temperatures and harsh
operating conditions can affect the ease
with which the fluorescent tube is struck.
The malfunction indication is only reset after
a further FT (manual or automatic) and goes
out after approx. 5 sec. or if the TBT of
min. 35 min. is not achieved:
– Charge the battery for at least 12 h continually
and then perform a partial service life test
(min. 35 min.). If the red LED does not go
out then, the battery capacity is no longer
adequate and the battery must be replaced.
Note: This malfunction cannot be reset by the
customer. It is only possible to check the faulty
battery set in the factory.
On the removal of the battery set from the
emergency luminaire the LEDs are automati-
cally switched off.
