2.3 SOPAS ET (PC program)
SOPAS ET can be used to set the GM32 parameters and provides access to the GM32 log-
book.
SOPAS ET runs on an external PC connected via the Ethernet interface (
→ p. 22, Figure 4) to
GM32.
2.4 Reference cycle
Correction of internal drifts in an adjustable interval (standard: 1 hour, setting: SOPAS ET),
via a command (with SOPAS ET) or via an external signal (option).
Measured value output during the reference cycle: Last valid measured value.
2.5 Check cycle
The check cycle is made up of the reference cycle, followed by the check and output of the
zero and check point (70% of upper measuring range value).
It is performed in an adjustable interval (with SOPAS ET), via a command (with SOPAS ET)
or via an external signal (option).
With the check cycle, the device is capable of performing the check of the zero point and a
reference point for each component without feeding test gases. The check cycle meets the
requirements of EN14181 and makes drift monitoring with test gases according to QAL3
unnecessary.
●Zero point
An internal zero point reflector is swiveled in time-controlled in adjustable intervals. The
emitted light is reflected back in the sender/receiver unit to the detector, the zero spec-
trum is evaluated with the calibration function and thus the zero points of all ducts
measured and output.
If the deviation from zero is > ±2% of the FS, Maintenance request is signaled.
●Check point
An internal swivel element with two reference filters and an NO-filled cell is swiveled in
during the check cycle in addition to the zero point reflector and the reference value or
concentration value measured. These check values are scaled to 70% of the selected
measuring range.
Maintenance request is signaled if the deviation from the setpoint value is > ±2% of the
FS.

2.6 Design of GM32
The GM32 Probe version comprises
●Sender/receiver unit (SR-unit)
The SR-unit contains optical and electronic subassemblies.
The concentration calculation of the sample gas according to the absorption spectro-
scope principle is performed in the SR-unit.
●Measuring probe with flange resp. purge air fixture ( → § 2.6.1)
●Purge air unit (for GMP measuring probe) ( → § 2.7)
Figure 2 GM32 Probe (version shown: GMP measuring probe)
2.6.1 Measuring probe
Probe types:
●Measuring probe with open measuring gap (GMP probe)
GMP probes require a purge air supply to protect the window against contamination.
●Gas diffusion probe (GPP probe) with gas permeable ceramic filter.
GPP probes are fitted with an automatically controlled heater to prevent condensate on
the windows.
Both probe versions have an integrated temperature and pressure sensor.
2.7 Purge air unit (for GMP measuring probe)
The purge air unit supplies filtered ambient air to the purge air fixtures and protects the
windows of the SR-unit from contamination and high gas temperatures.
The purge air is blown into the gas duct through the “flange with tube”.

Preparation on the Gas Duct Side
3.1 Preparation of sampling point
b Determine the installation location.
Observe the ambient conditions of the GM32 (
→ p. 67, §9.2).
b Observe the space requirements for the SR-unit ( → p. 72, §).
Provide for additional space for maintenance work (swiveling the housing door open,
pulling the measuring probe out).
b Determine the installation location for the connection unit.
Observe the maximum line lengths (
→ p. 22, Figure 4 or as planned).
b Provide the power supply for the connection unit and, when necessary, for the GPP
probe.
Observe the power requirements (
→ p. 67, §9.2).
b Lay the signal lines.
b For GMP probe: Determine the installation location for the purge air unit ( → p. 22,
Figure 4 resp. as planned).
Provide clearance for changing the filter element (→Technical Data of purge air unit).
3.1.1 Checking the scope of delivery
b Check the scope of delivery according to the order confirmation/delivery note.
●The basis for the determination of the sampling point is the preceding proj-
ect planning (e.g. based on the SICK application questionnaire), the infor-
mation in the final inspection record of the GM32 and the regulations of
the local authorities.
●The equipment operator is responsible for the determination of the sam-
pling point (e.g. the determination of a representative sampling point).
●The equipment operator is responsible for the preparation of the sampling
point (e.g. load carrying capacity of the welded flange).
b Compare the data of the final test record with the data of the order confir-
mation - they must be identical.

Preparation on the Gas Duct Side
3.2.2 Installing the “flange with tube” on the gas duct
1Make a cut-out in the gas duct for the “flange with tube”.
2Insert the “flange with tube” so that the mark (TOP) ▴points upwards vertically (irre-
spective of the gas duct angle) and attach the “flange with tube”.
– The tube must project at least 30 mm into the gas duct.
– Make sure the probe does not collide with other devices or fittings.
– Tilt the tube slightly downwards (approx. 1°).
This allows any condensate to drain off.
3Now fix the “flange with tube” properly to the gas duct.
Make sure that the alignment of the flange does not change.
4If necessary, attach duct insulation (protect GM32 from heat).
3.3 Installing the connection unit
●The length of the line to the GM32 complies with project planning.
b Provide threaded bolts (4) to screw on the connection unit ( → p. 72, §31) and screw on
the connection unit.
⊗Do not make the electrical connection to the connection unit yet.
WARNING: Danger resulting from gases in the gas duct
Hot and/or noxious gases can escape during work on the gas duct, depending
on the equipment conditions.
b Work on the gas duct may only be performed by skilled persons who, based
on their technical training and knowledge as well as knowledge of the rele-
vant regulations, can assess the tasks given and recognize the hazards
involved.
IMPORTANT: Observe the ambient temperature of the GM32
b When the gas duct is hot, insulate the duct and flanges so that the
GM32 is protected from excess temperatures (
→ p. 67, §9.2).
