4 Function and device design
4.1 Function
Application range
The YL6S product series provides both an audible and visual alarm which can be used
to alert, warn or draw attention to a machine malfunction/start-up or any number of safety
related issues. The audible and visual signals can be operated independently or in
combination. Corrosion resistance is a key feature of the device; it is therefore ideally
suited for applications in the harshest of environments, both onshore and offshore.
In hazardous areas, the devices feature explosion protection for ATEX/IECEx Zones 1 &
2 for gas and 21 & 22 for dust. The device covers gas groups IIB & IIC, as well as dust
protection for IIIC.
Mode of operation
The flashing beacon is considered to be an additional alarm when used for
alerting/evacuating in buildings and systems.
The device is not suitable for continuous operation.
The service life of the xenon flash tubes is guaranteed for the following number of flashes:
DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.
• Use the device only according to the operating conditions described in
these operating instructions.
• Use the device only for the intended purpose specified in these
operating instructions.

7.2 Mounting/dismounting, operating position
DANGER
Explosion hazard due to improper mounting!
Non-compliance results in severe or fatal injuries.
• Only operate the device if it is not damaged.
If the thread is damaged, replace the device immediately.
• Only install the device in a clean and dry operating environment.
• Only mount the device on a wall or on a suitable surface.
• Carefully protect exposed joint surfaces from damage, dust and dirt.
• Install end flanges without applying force (without hammer and tool)
in straight alignment.
• If necessary, fit core end sleeves gas-tight and using a suitable tool.
DANGER
Explosion hazard due to electrostatic discharge!
Non-compliance results in severe or fatal injuries.
Do not use the device in strong charge-generating environments!
The following processes/activities should be avoided:
• Accidental friction
• Particle flows
DANGER
Explosion hazard due to open drilled holes, unused cable entries and cable
glands!
Non-compliance results in severe or fatal injuries.
• Only use cable entries and stopping plugs that have been separately
checked and certified in accordance with Directive 2014/34/EU (ATEX)
and IECEx (CoC), and which technically correspond to the state of
technology given in the certificate.
• The IP level of protection of the cable entries and stopping plugs
must at least correspond to the IP level of protection of the device
(see marking on the device).
• When selecting cable entries, observe the type of thread and thread
size in the component documentation.
• Seal the thread with non-curing thread sealant in order to guarantee the
IP66 degree of protection.
• Always close unused drilled holes, cable entries and cable glands using
approved stopping plugs or plugs. Observe IEC/EN 60079-14 for this.
• Installation of the cable gland must be performed in accordance with the
manufacturer's instructions.
• The cable entry temperature may exceed 70 °C.

7.3.4 Mounting the device
• Lift the flashing beacon flange towards the device.
• Connect the PCB using the connector.
• Mount the flashing beacon flange.
• Replace the M5 x 25 cheese-head screws and tighten them to a tightening torque of
4 Nm.
7.3.5 Mounting the earth connection
Use of metallic cable entries
A slip on earth tag is provided for each device.
• Connect the slip on earth tag to the external earth bolt.
Device material
The GRP material used for the enclosure has electrically conductive properties.
The material is antistatic and prevents the build-up of electrical charges on its surface.
Surface resistivity < 108 Ω according to IEC/EN 60093.

Screws and seals
The cheese-head screws are delivered with Nyltite seals.
• Before mounting, check the seals for damage.
• Replace damaged seals.
• Use seals a maximum of 5 times.
• When using screws on a flat surface, note the seal on the screw
head – see figure.
