Cable connection
The cable entries should be equipped
with fitting, ATEX-certified, flame-
proof cable glands for gas group
IIB, with or without ATEX-certified,
flameproof thread adapters.
The adapter and the cable must
comply with the operating con-
ditions.
The temperature of the cable entry
may reach up to 70°C. Unused
cable entries must be closed using
fitting, ATEX-certified, flameproof
blind plugs for gas group IIB with
or without ATEX-certified, flame-
proof thread adapters (per default,
the manufacturer has included one
ATEX-certified blind plug).
Fitting ATEX-certified, flameproof
cable glands, thread adapters and
blind plugs, which are certified as
equipment (not as components) by
means of an EC type examination
certificate in accordance with direc-
tive 94/9/EC, may also be used, as
described above. The terminals
can accommodate cables with a
conductor cross-section of 2.5 mm
2
.
The circuit board can be lifted
slightly within its guides, in order to
access the terminals more easily.
Selecting the signalling tone
– The signalling tone should be
selected in an approved work-
shop.
– In order to select a signalling
tone, use the table with the
signalling tones and the corre-
sponding selector switch settings
(page 4).
– Check to see if you have selec-
ted the correct signalling tone for
the first and the second stage.
– Check the signalling tone several
times before re-assembling the
signalling device.
Assembling the signalling device
–
Connect the cable with the
circuit board of the flameproof
unit, and make sure the connector
has engaged.
– Make sure the circuit board unit
is correctly situated in the house
guidings. Check to see if the flash
tube is situated in the centre of
the glass dome and if it is visible.
– Join the sounder flange and the
main housing again, but make
sure the connecting cable does
not get pinched between the
housing parts, and does not
come to rest over the edge of
the circuit board unit or between
the head of the earth screw and
the flameproof housing.
the device with the acoustic
hood directed downwards.
– The cable must be connected to
the device through a sealing part
situated directly at the cable entry.
– A suitable sealing part would be
a sealing threaded gland or a
sealing cable gland.
The choice of sealing parts
depends on the gas group in
question and of the method of
installation.
– The YL 6 housing is equipped
with two cable entries, of which
one or both may be used. This
depends on the number of cable
conductors necessary for the
configuration of the application.
– The cable and its seal should be
mounted in an approved work-
shop; how to assemble the
cable and its seal is described
below.
IMPOR
TANT:
– Please be especially cautious
when removing or replacing
parts belonging to the flame-
proof housing.
– Open surfaces of connections
must be protected and should
not make contact with dust or
dirt, or bump against any other
items.
– The end flange must be assem-
bled with great precision, and by
no means by use of excessive
force. The flange must not be
hammered or levered using a
metallic item or the fastening
screws of the flange.
– The flange should fit effortlessly
into the housing.
Remove the acoustic hood from
the sounder flange by removing the
three self-tapping screws situated
in the dome of the acoustic hood.
Unscrew the four hexagon socket
screws (hexagon socket screw
wrench 4 mm (5/32“)) with the two
washers and the O-ring from the
flange. These screws are not com-
pletely tightened, if the sealing has
not been undertaken at the factory.
I
MPOR
TANT:
Please pr
oceed with extreme cau-
tion when removing the sounder
flange from the main housing. The
hooter horn must not be used as a
lever.
– Pull the cable off of the circuit
board of the flameproof unit.
– The exposed connections must
stay clean and undamaged.
– Place the sounder flange on a
clean piece of packaging material.

OPERA
TION
The YL 6 is intended for use in
hazardous areas.
It has been certified by Baseefa
Ltd. in accordance with the stan-
dards EN50014 and EN50018
ATEX.
For use in hazardous areas classi-
fied by gas group IIB, correspon-
ding versions are available.
A signalling device, which has been
approved for a certain gas group,
may also be used in areas subjec-
ted to a less dangerous gas group,
i.e. IIB devices may also be used
for gas group IIA.
The YL 6 is intended for outdoor
use. It fulfils the demands of
standard EN 60529 for the IP66
degree of protection.
INST
ALLATION
Fastener is included. Bor
e diameter
9 mm. Distance between bore-
holes 75 mm.
GENERAL
The YL 6 must be installed in
accordance with this manual. The
YL 6 must also be installed in
compliance with the relevant pro-
fessional and legal demands.
PREP
ARATIONS
Make sur
e the power supply has
been switched off prior to installa-
tion.
A.
Check that you have the cor
rect
signalling device, i.e. the one
that meets the system require-
ments:
– Gas group and temperature
– Operating voltage
– Selected signalling tone
– Correct colour of the strobe
light sphere
– Suitable fixing location
– Cable connection and
method of installation
B.
Fixing location
–
Choose a suitable fixing location
for the device, considering the
area to be covered by the sig-
nalling tone and the strobe light.
– The surface of the installation
area should be level and consist
of a material that is able to carry
the load of the device.
– The device must be mounted
with the acoustic hood on top.
– The device should not be instal-
led in an area where it will be
exposed to direct sunlight.
– In exceptional cases the YL 6
may be placed horizontally. Not
allowed, however, is installing
