Configuration, installation, commissioning
6.4.2 Commissioning
First plug in the connection cable to the measuring probe, using the plug
connector and secure it with the cap nut.
The cap nut screwed connection is sealed with a rubber ring. The nut must be
well tightened
against the resistance of this rubber ring, to make sure of a
reliable seal at the connection.
The supply unit is now supplied with current, so that the purge air hose pushes
clean ambient air through the dust measuring lance. A flow of air must be
perceptible at the diaphragm openings.
Figure 6.12: Diaphragm openings
If this is the case, the dust measuring probe can be inserted into the duct
flange together with the flange seal. The red dot at the top of the welded-in
flange must lie alongside the red dot on the probe flange. The probe is then
fastened to the duct flange with four self-locking M10 nuts.
Before the connection cable can be disconnected and reconnected, the
miniature fuse holder for the fuse L1 in the supply unit must be swung open.
The measuring lance then performs a reset and an auto-initialisation. Any
measurement results collected previously but not saved are lost when this is
done!
Note also that removing the will stop the purge air supply! Therefore first take
the D
