WARNING!
All activities described in this chapter must be performed by qualified, authorised personnel
only under observance of requirements from the following regulating bodies:
Official Journal of the European Union L 96/309, Directive 2014/34/EU of 26 February
2014 relating to equipment and protective systems intended for use in potentially
explosive atmospheres (recast)

Equipment – General requirements
WARNING!
Security relevant functionality.
Risk of death and risk of material damage if commissioned incorrectly.
Commissioning may only be performed by authorised specialist personnel.
DANGER!
For ignition attempts, there is a risk of flashing caused by residual gas in the gas tube
or gases in the environment.
For pilot attempts, secure the hazard area in front of the pilot burner mouth.
Clear the pilot burner with purge air from residual gas as necessary.
The ignition should ideally only be tested in installed status.
Integrate the device into the system control
Integrate the relay switch contacts of the flame scanner into the safety-oriented system con-
trol. You must observe and comply with the requirements of the DIN EN 298 and the regional
requirements.
In addition, you must ensure that the function or neutral position of the respective
contact is checked regularly - in accordance with the requirements - by the superordinate con-
trol system and/or burner sequencer.
Ensure signal detection
NOTICE
In unfavourable conditions, the energy of the ignition spark can interfere with the ionisation
signal in such a way that it is not possible to perform a measurement.
To prevent this, a time section of approx. 0.5 s before expiry of the ignition safety time, in which
a secure signal detection can take place, is to be set on the system control.
