Conformity with standards

The luminaire is suitable for use in zone 1, 2
and 21, 22 hazardous areas acc. to
EN/IEC 60079­10­1 and EN/IEC 60079­10­2.
The luminaire is conform to the standards
specified in the Declaration of conformity,
enclosed separately.
References to standards and directives in these
operating instructions always relate to the latest
version. Other additions (e.g. details relating to
the year) shall be observed.
4.
Installation EXIT
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 (IEC/EN 60079-14)!
Transport and storage of the luminaire is
permitted in original packing and specified
position only!
4.1
Opening and closing the light fitting
­
Unscrew the four screws of the cover.
­
The cover can be opened to the molded
hinges. For ease of installation, the cover can
be removed out of the hinges.
If putting down take care to prevent
scratches on the silk screen cover.
4.2
Installation of the fitting
Warning - Hazard due to electrostatic
charges!
Luminaire must not be installed in the
vicinity of charge-generating processes!
The luminaire shall be fitted by using the four
mounting clips with suitable fixing screws
(Ø: 5 mm, fig. 1) onto a suitable surface.
4.3
Mains connection
The electrical connection of the device may
only be carried out by skilled staff
(IEC/EN 60079-14).
Open the cover as described.
Pass the cable through the certified Ex e / Ex t
cable entry M 20 x 1,5. Use
sealing inserts 1,2 and 3
for cables from 5.5 to 7 .0 mm Ø,
sealing inserts 1 and 2
for cables from 7 .0 to 9.0 mm Ø and
sealing insert 1
for cables from 9.5 to 13.0 mm Ø.
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 2.7 Nm).
When closing the gland with a blanking plug,
always use sealing inserts 1+2!
Explosion protected LED­exit luminaire
Series: EXIT N
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 Ex blanking plugs (min. IP66)!
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. 2).
Take care not to pinch any conductors.
The circuit can be connected via a small switch
on the board. Please refer "Type of connection".
Install the protective cover with the four screws
(Test torque 2.4 Nm).

Function
5.1
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. 3).
See also: table of LED indication status.
5.2
Adjustment
Because of the light source energy of the LED
diodes, the luminaires are used almost
exclusively as luminaires for emergency exit
signs.
After removing the hood, it is possible to adjust
to two operating positions by means of the small
switch situated on the front of the plate with the
inscription "Drawing 6A".
"Permanent lighting" position
Position "ON", delivery position.
The light goes on in normal service and
emergency situations.
"Emergency lighting" position
Fig. 4
Switch on the LED side.
Position "OFF", delivery position.
The white LED diodes are off in normal service
conditions.
Loading status and possible sources of
interference will be indicated.
In case of power failure, the white LEDs shine.
The yellow LEDs function in emergency
situations.
The weekly function test and the partial
operating time test, performed every 3
months, will be set in the position ´OFF´.
5.3
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. 3.
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. 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
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
self­discharge in normal operation is automatical­
ly recharged controlled by the microprocessor.
5.4
Automatic function test
5.4.1 Function test (FT)
A function test (FT) is performed automatically.
5.4.2 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.
5.5.
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 yellow is switched to battery
operation.
The residual capacity available is indicated by the
5 green light emitting diodes, see figure 3.
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 L as
well as between PE and N.
– measuring voltage: max. 1 kV AC/DC
– measuring current: max. 10 mA
Mind: There must no insulation measure-
ment be carried out between L and N, since
that would destroy the electronics
(mains input fuse in the unit).
