2.1 Classification of the Safety Instructions and Warnings
The following symbols are used in this document to draw the user's attention to important safe-
ty information. They are located at points where the information is required. It is essential that
the safety information is observed and followed, and that applies particularly to the warnings.
DANGER!
This draws the user's attention to imminent danger. If it is not avoided, it will result in death or
very serious injury. The plant including its surroundings could be damaged.
WARNING!
This draws the user's attention to the possibility of imminent danger. If it is not avoided, it may
result in death or very serious injury. The plant including its surroundings could be damaged.
CAUTION!
This draws the user's attention to the possibility of imminent danger. If it is not avoided, it may
result in minor injuries. The plant including its surroundings could be damaged.
NOTICE
This draws the user's attention to important additional information about the system or system
components and offers further tips.
The safety information is incorporated into the instructions.
Thus, the operator is requested to:
1 Comply with the accident prevention regulations whenever work is being carried out.
2 Do everything possible within his control to prevent personal injury and damage to prop-
erty.

2.2 Product Safety
NOTICE
This product is state-of-the-art technology and complies with the generally accepted
safety-related rules and regulations.
Every device is tested before delivery to ensure that it is working properly and safely.
Only use this product when it is perfect condition and in accordance with the manual, the
prevailing regulations and guidelines and the applicable safety and accident prevention
regulations.
NOTICE
The risk of fire, traffic, wind, tidal waves and earthquakes depends on the installation situation
on site and must be evaluated separately.

2.3 Product-specific Dangers
Installation and commissioning
WARNING!
All following warnings must be observed to avoid personal injury and damage to
property and the environment.
WARNING!
During the operation of electrical devices, certain parts inevitably have dangerous
voltage. If the following notices are not observed, severe bodily injury and property
damage could thus occur.
WARNING!
The integrated flame scanner is not provided with a direct switch-off of the fuel valves.
The subsequent signal processing must be carried out in the control system, which is
adapted to suit the combustion plant. The device may only be used with burner control-
lers which comply with local standards.
WARNING!
The integrated flame scanner is a safety device. Only specialist staff of the manufactur-
er or people approved by the manufacturer may intervene. No interventions by anyone
else are permissible. This applies, in particular, in the event of a defective fuse.

2 General Safety Instructions
NOTICE
The integrated flame scanner of the pilot burner is a safety component for gaseous and liquid
fuels. When gas consumers according to EN 298 are used, they are subject to the (EU) 2016/
426 Gas Appliance Directive (GAR).
• The applicable national safety regulations and standard notes are to be observed
in each case.
• The installation of the device must be carried out precisely according to the directions in
these operating instructions.
• Only connect the device when the technical data of the device matches the data of the
peripheral equipment.
• The device may only be operated in an environment for which it is specified in accordance
with the technical data.
• None of the safety labelling or markings may be removed from the device.
• No unauthorized modifications or attempts to repair the device
are permitted.
• Make sure that no spliced strands can come into contact with any of the adjacent connec-
tions. Use appropriate end splices.
• Make sure that the power cables are not interchanged between L and N.
• The plug connectors X13, X14, X15 and X16 do not have a secure disconnection from the
mains voltage.
• To replace or disconnect the plug connectors, all poles of the plant must be disconnected
from the mains.
• Measuring circuits must feature a secure disconnect according to EN 61140 "Protection
against electric shock " for active parts; for this reason, use only measurement and
evaluation devices which have a double or reinforced insulation.
• In order to provide for operating safety, make sure when installing the output contacts that
the circuitry of the radio interference suppression to be provided by the user is carried out
in such a way that there is no risk of shorting out the relay contact output (flame signal) by
defective component parts of the suppressor circuitry
• Work on electrical systems or equipment may be performed only by a certified electrician
or trained personnel managed and supervised by a certified electrician according to the
electrical engineering regulations.
• Machine and plant parts on which inspection, maintenance, and repair work is performed
must be de-energised and secured against reactivation. First make sure the enabled parts
are de-energised, then earth and short-circuit them. Secure adjacent, live parts against
accidental contact by covering them.
• The electrical equipment of the system must be checked regularly. Defects must be
reported immediately and remedied.
• If work on live parts is necessary, a second person must be involved who can press the
emergency stop or main switch if required. Block off the working area with a red-and-white
safety chain and a warning sign. Use only voltage-insulated tools.
• In case of fire in electrical systems, do not extinguish with water under any circumstances.
Only the provided fire extinguishers may be used.

3.4 Important Information about the Product
3.4.1 Life Cycle
The device has a limited lifespan. It is designed for 250,000 switching cycles at nominal firing-
rate and thus type-tested. With 50 switching operations per day, this results in a lifespan of
approx. 10 years.
Increased firing-rate due to extreme operating conditions (e.g. temperature, vibration, contam-
ination, etc.) can significantly reduce the service life.
The system operator is responsible for adapting the frequency of regular safety-related
inspections to the operating conditions.
At the end of its service life, the device must be disposed of properly.
