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 green 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 this instructions as well other
applicable stipulations are to be checked!
The battery box will be fixed factory side at the
eLLK 92/ eLLS 08 .. NIB lighting fitting or can be
separately mounted at the front end with suitable
fixing material.
Observe the safe and correct mounting as
well as the proper fit of the cable glands for
the degree of protection IP66!
sockets
The mounting device can also be the steel
enclosure eBB 02. The cable with plug GHG 571
(eXLink) on it must not be shortened or modified
(fig. 4).
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 5).
The battery box is to be closed again by tighten-
ing the two fixing screws. Take care to tighten
these two screws hand-tight only ! 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 recommend-
ed 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;
or
-
The minimum operating time during the auto-
matic partial service life test is not achieved
(< 30 min.).
The "red flashing LED" malfunction indication
remains until the fault is rectified.

The red LED indicates continuously if:
-
A fault occurs in the battery, e.g. accumula-
tor fault. In this case the battery should be
replaced, as emergency lighting operation can
no longer be assured.
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 operat-
ing 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 continu-
ally 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 automatically
switched off.
7. Maintenance
When replacing a defective component,
observe the following: Isolate the equipment
from the power supply before opening it!
Only use certified genuine CCH/CEAG spare
parts!
When performing maintenance, servicing,
and testing on explosion protected equipment
observe the applicable regulations,
e.g., IEC/EN 60079­17!
Servicing:
When servicing, in particular those components
that affect the explosion protection, will have to be
checked, e. g.:
-
Housing and protective bowl for any cracks or
damages.
-
Gaskets for their perfect condition.
- Terminals and blanking plugs for their firm fit.
-
Because of the risk of an electrostatic charge,
the light fitting shall only be cleaned with a
damp, non-fibrous cloth or sponge!
Only use customary household washing-up
liquid diluted in water as specified! The water
temperature may be max. 50°C.
After that, rinse with clear water to prevent the
risk of tension cracks in the protective bowl!
- One or two times a year a complete dis­
charge of the battery (emergency opera­
tion until the emergency lamp will be off)
will increase the usable service life of the
battery and is strongly recommend!
The battery set NIB 2710-3 (with LED indication)
cannot be fitted instead of the battery set 2710-1
or 2710-02 in existing emergency luminaires
eLLK 92 N/Ni. For this purpose the battery set
2710-02 available as a spare part is to be used.
Both types of battery sets may be handled and
replaced within a zone 1 and 21 hazardous area.
Subject to alteration and supplement of this prod-
uct range. Regarding waste disposal, observe the
respective national regulations!
