4. Installation
The respective national regulations as well as
the general rules of engineering which apply to
the installation and operation of explosion protected
apparatus will have to be observed!
Transport and storage of the luminaire is permitted
in original packing and specified position only!
Opening and closing the light fitting
Unscrew the four recessed head screws of the
cover
Remove the protective cover. If putting down take
care to prevent scratches on the silk screen cover
Installation of the fitting
The luminaire shall be fitted by using the four
mounting clips with suitable fixing screws
(Ø: 5 mm, fig. 1) onto a suitable surface.
Mains connection
After opening the cover unscrew the two screws of
the LED-printed board (fig.1). Turn the printed board
downwards using the two guided springs (fig. 2).
Pass the cable (8 to 17 mm) through the certified EEx
cable entry M 25 x 1,5. Use both sealing inserts for
cables from 8 to 12 mm, and the outer sealing insert
only for cables from 13 to 17 mm.
Pay attention to the proper fit of the remaining
sealing insert in the certified cable gland.
In case of unused cable entries, remove their
protective cover and close the entries with a blanking
plug (torque of 3.5 Nm). When closing the gland with
a blanking plug, always use both sealing inserts!
When metal cable entries are used, the protective
caps of the unused entries are to be removed and
the entries to be closed with certified EEx blanking
plugs IP 66!
) in these
Attention!
Only fix laid cable may be used for connection!
If cable glands from other manufacturer are
used the instructions regarding strain relief and
clamping capacity must be observed!
Connect the conductors to the terminals L, N and PE
in accordance with the terminal marking (see fig. 3).
Remount the LED-printed board into the housing.
Take care not to pinch any conductors. Install the
protective cover with the four screws. Tighten the
screws only hand-tight!
Changing of the legend
To install the correct legend open the 4 scews
(fig. 4) together with the 2 brackets at the cover
frame. Remove the old legend. Put the selected new
legend (fig. 5( onto the protective glas panel. Fix the
legend with the two brackets and scews on the
frame. Close the frame onto the enclosure.
5. Function
System modes
Luminaires equipped with LED-lightsources are used
normally as exit-luminaires due to the light output of
the LEDs. Therefor these light fittings have to be
operated continuously (Independent system mode)
Display
The luminaire is fitted with a microcomputer for
charging and monitoring and with a display composed
of 7 light emitting diodes. The five green LED's
indicate the battery's charge state and available
capacity. The red LED signals possible failures, the
yellow LED signals the emergency operation (fig. 6).
See also page 7: table of LED indication status.
Charging
The microcomputer controlled charging system
measures the charging and discharging current and
transmits it to a capacity meter. Five green light
emitting diodes indicate in 20%-steps the actual
charge state of the battery, see fig. 6, 7.
Overcharging is prevented by means of this charging
control dependent on the capacity. Only the energy
drawn is recharged. The so-called memory effect is
thus also prevented.
At temperatures below -5°C and above +35°C the
battery will not be fully charged for electrochemical
reasons.
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. 7). 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 emergency
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 automatically
recharged controlled by the microprocessor.
Automatic function test
Function test (FT)
A function test (FT) is performed automatically. During
this process the emergency luminaire is switched to
battery supply for approx. 5 min. and tested.
Partial operating time test (TBT)
Every 3 months a partial operating time test is
performed. If no emergency lighting operation > 30
min. has occurred during the last 3 months.
During this test emergency lighting operation is
performed for approx. 35 min.
Emergency lighting operation
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.
The residual capacity available is indicated by the 5
green light emitting diodes, see figure 7.
6. Taking into operation
Prior to operation, check the light fitting for its
proper functioning and installation in compliance
with these operating instructions and other
applicable regulations!
Only carry out insulation measurements between PE
and the external conductor L1 as well as between
PE and N.
– measuring voltage: max. 1 kV AC/DC
– measuring current: max. 10 mA
Mind: There must no insulation measurement be
carried out between L and N, since that would
destroy the electronics (mains input fuse in the unit).
7. Maintenance
Observe the national regulations applicable to the
maintenance, servicing and test of apparatus for
explosive atmospheres e.g EN 60079-17 as well as
the general rules of engineering!
Battery module replacement
When the battery shows low capacity because of
ageing the battery module has to be changed.
Cut the apparatus off the voltage before
opening it!
Remove the printed board and disconnect the 3 wires
L, N and PE from the terminal (see mains
connection).
Ë Ì
Remove the two jumpers and
contacts and demount the complete board from the
enclosure (fig. 8)
Now the printed board is voltage-free and may
be carried in hazardous area without additional
protection.
Outside of the hazardous area the battery module
can be changed. Open the two screws M4
disconnect the 4 wires at the terminals
Compress the snap-on fasteners
of the printed board and remove the battery module
(fig. 10 and 10a).
Assemble the new battery module in reverse order.
Servicing
When servicing, in particular those components that
affect the explosion protection, will have to be
checked, e. g.:
Housing and protective glass for any cracks or
damages.
Gaskets for their perfect condition.
Terminals and blanking plugs for their firm fit.
Repair
Prior to replacing or removing any components,
observe the following:
Cut the apparatus off the voltage before opening it
or carrying out repairs! Only use certified genuine
CEAG/CCH spare parts! (See CEAG/CCH spare
parts list).
Subject to alteration or supplement of this product
series.
Regarding waste disposal, observe the relevant
national regulations! The plastic materials are
marked with material identifications.
