5.2 Transport
Avoid rough impacts. Use the original packaging for transport where possible:
The mouldings used in it ensure safe transport.
5.3 Installation
5.3.1 Instructions on selecting a suitable installation point
The correct viewing position must be determined in order to guarantee optimal
and selective flame monitoring. This must ensure that the flame is easily
visible for the flame monitor in all load ranges of the burner and, if possible,
that there are no flames from adjacent burners in the monitoring axis.
The D
− LX 200, D − LX 720 has an angle of view of approx. 6°.This should
always be oriented towards the root of the flame (ignition point of the flame),
i.e. the first third of the flame.
5.3.2 Mounting the flange
The D − LX 200 is mounted on a sighting tube with a G1¼" male thread
connection.
Figure 5.1: Safety screw
First of all, fasten the (black) front part of the Compact Flame Monitor with the
purge air connection to the sighting tube.
The (blue) device part can then be tightened on it by hand with the connecting
nut located on the front part.
The flame monitor should be routinely checked to ensure that the optics are
clean and that the monitor is firmly mounted in the front part.
The connecting nut is provided with fastening protection by a safety screw (2
mm Allen key). Ensure that the flame monitor has been mounted correctly and
that the safety screw is tight.
Various swivel mounts in series D-ZS 033 are available for optimising
alignment with the flame (see Figure 5.2).
