1 Overview
l.± Benefits ofthe GM 9O1
^- CO analyzer: GM901 measures theCO contentdirectly inthegas duct.
^ Bus capability:using a CAN bus, the evaluationunit canbe mounted ata
distance ofupto 1000 m from the measuringpoint,e.g. inthe controlroom.
^- Easy to mount and connect.
> Shortstartuptime - to install the opticalunits and switch onthe powersupply.
^- User-friendly operation by means of function buttons onthe evaluation unit:
-for settings the display and outputfunctions
-for configuring the deviceparameters
^ Low maintenance requirements, no test gases required.
*• Variablemeasurementvalueoutput: ppm, mg/m3, or mg/Nm3.
^ Measurementvalue,measuringrange, and limitvalues are visible onthe
display. Additionaltemperaturedisplay and plaintextinformation onthe
operatingmode.
> Integrateddiagnosisfunction.Diagnosisdata canbe called upfor warnings
and errormessages.
±.2 Applications
The GM901is designed for instant and no-contactmonitoring oftheCO concen-
tration, for example, for processcontrolpurposes inthe followingareas:
^- Powerstations
> Coal processingplants
^- Refuseincinerationplants
^ Plants inthe cementindustry
>• Paperindustry
^- Pharmaceuticalindustry
> Melting/steel industry
^ Glassindustry
^ Chemicalindustry

Measure
The gasflowinthe vicinity ofthe measuringpoint
should be homogeneous.
Measuring gas temperature: s 300 °C;
highertemperatures on request.
Dustconcentration: < 1 g/m3 x m
A highdustcontent inthegas duct can impair the
measurement.
Duct pressure:
•A purge-air unit isnot required if there isa
constantpartialvacuum inthe duct. Air filter
set recommended.
•A purge-airunit is required in pressurized
plants.Pleaseconsult the SICK Customer
Servicedepartmentwithregard tothe correct
fan type.
Steelducts: the device is designed for installation
in steel ducts.
Brick or thick-walledducts:modified flange with
pipe required. Canbe provided bythe customer
or designed by SICK.
Suitablereinforcements or supportconstructions
must be provided on thin-walledducts to ensure
that the transmitter and receiver are permanently
aligned.
The size and position ofthe aperturemust be sel-
ected in such a way thatsufficientspace is pro-
vided forthe transmitter and receiver.
Some ofthe ductinsulationmust be removed
and sufficientspaceprovided for installation and
maintenanceactivities.
Ifthe device is mountedoutdoors,sufficientspace
should be provided forthe weatherproof cover.
The unit should be installed ata position that is
freelyaccessible.Max.distancefromtransmitter
and receiver:
- standard: 2 m
- withextensioncable: 17m
- For cable lengths upto 1000 m:
with connectionunit(accessory)
The unitshould be mounted ona flat surface.

Tab. 1: Checklist
The purge-airsupplymust be installed atan
equal distance from the transmitter and receiver
to ensurethat theairflows uniformly.
Sufficientspaceshould be provided for replacing
thefiltersetand dustcollector.
If the unit is mountedoutdoors,sufficientspace
should be provided for installing/removing the
weatherproof cover.
The temperature ofthe purge air entering the
duct must not fallbelow thedew point. If neces-
sary, the purge air must be heated (SICK heaters
are recommended).
"temperature"of the intake air:"6~°C"<~T < 55 °C.
If Т < О °С, heat the purgeair.
The intakepurge air should be free of dust.
П
- Height of platform:approx. 1.5 m below the inten-
ded location forthe transmitter and receiver.
- Lighting anda powersupplyshould be installed at
the measuringpoint to facilitateservicing.
All ofthe device components should be safely
accessible.
Always observe the nationalaccidentprevention
regulations!

2.2 Installation Sequence
1. Step: Carry outallofthe planning activities (see 2.1 "Checklist")
2. Step: Mount theflangeforthe transmitter and receiver atthe measuring
point
3. Step: Check the wiring atthe siteusing the wiringspecifications(see
3.2.1"WiringSpecifications/Interfaces tothe Evaluation Unit")
4. Step: Laythe cables and signalleads
5. Step: Check allthe connections(see 3.2 "Preparations for Electrical In-
stallation")
6. Step: In pressurizedplants:mount the (optional)purge-airunit and check
whether itis functioningcorrectly
7. Step: Mount the evaluationunit
8. Step: Mount the transmitter and receiver
9. Step: Ifthe cablebetween the receiver and evaluationunit is longerthan
17m: install the connectionunit(accessory)
10. Step: Ifthe devices are installedoutdoors:mount the weatherproof
covers
