START-UP
7.6 Starting measuring operation
This Section describes the final preparations at the measuring point at which the Gas
Analyzer with Measuring Probe GM35 starts measuring operation.
For this purpose, the SR-unit with mounted measuring probe must be installed at the
measuring point.
▸ If adjustment was carried out away from the measuring point, carefully transport the
adjusted SR-unit with measuring probe to the measuring point.
7.6.1 Starting up the purge air supply
Only when purge air is
used
This Section is only applicable for GM35 configurations with GMP probe for which a purge
air supply is used. If the GPP probe is used, go to page 89. The purge air unit has already
been installed and checked ready for operation during device installation (see page 37).
▸ Connect the short hose piece on the pressure difference sensor securely to the purge air
connection of the GMP measuring probe with a hose clamp.
▸ Connect the two 6.3 mm flat pin bushings of the installed signal cable to terminals 2
and 3 (NO and COM, NC contact) of the pressure difference sensor.

Connecting the purge air supply to the SR-unit
1 Position the SR-unit with measuring probe in the immediate vicinity of the flange with
tube installed on the sample gas duct to connect the purge air hose, and to insert the
measuring system in the duct with the purge air supply running.
If the angle flange, Part No. 2 017 833, was used for adjustment, the measuring system
is usually already located directly at the duct-side flange.
2 Switch the power supply for the purge air unit on briefly to check the function and to
remove any dust that may have penetrated the purge air hose.
CAUTION: Follow the work sequence
To prevent damage to health and the measuring system, carry out the steps
described in the following in the specified sequence. Always observe the
relevant safety information. Only position the SR-unit with measuring probe in
the sample gas duct in accordance with
page 89. In systems using a purge air
supply, the purge air supply must be put into operation first as described on
page 88.
