Installing the transm<strong>it</strong>ter<br />
Installing the transm<strong>it</strong>ter<br />
Preparing for installation<br />
The performance and effectiveness of the entire system depends essentially on the<br />
pos<strong>it</strong>ion chosen for installing the transm<strong>it</strong>ter.<br />
The following should be noted during installation:<br />
— Local requirements and regulations governing the installation of gas measuring<br />
systems.<br />
— Relevant regulations concerning the connection and routing of electric power<br />
supply and signal lines.<br />
— The full scope of environmental factors to which the transm<strong>it</strong>ter may be exposed<br />
(ambient cond<strong>it</strong>ions: see Technical data, page 20).<br />
— Physical properties of the gas to be measured:<br />
For gases w<strong>it</strong>h a dens<strong>it</strong>y lower than that of air, the transm<strong>it</strong>ter must be located<br />
above any possible leak or at the highest point at which large concentrations of<br />
gas may occur.<br />
For gases and vapours w<strong>it</strong>h a dens<strong>it</strong>y greater than that of air, the transm<strong>it</strong>ter must<br />
be located below a possible leak or at the lowest point at which such gases and<br />
vapours may occur.<br />
— The specific uses (e.g. possible leaks, ventilation cond<strong>it</strong>ions, etc.).<br />
— Accessibil<strong>it</strong>y for the necessary maintenance work (see Installation instructions for<br />
the <strong>Polytron</strong> docking station).<br />
— All other factors and cond<strong>it</strong>ions which could have a negative effect on the installation<br />
and operation of the system (such as vibrations or varying temperatures).<br />
— We recommend installing a reflective shield if the un<strong>it</strong> is exposed to strong sunlight.<br />
— The transm<strong>it</strong>ter must be installed vertically (sensor facing downwards).<br />
— The transm<strong>it</strong>ter has been tested w<strong>it</strong>h regard to <strong>it</strong>s weather-resistance and may be<br />
installed out of doors. Use of a splash guard is recommended to protect the sensor<br />
from splashing water, dust and wind.<br />
In explosion-hazard areas:<br />
Observe the national regulations concerning electrical equipment in<br />
explosion-hazard areas.<br />
The <strong>Dräger</strong> <strong>Polytron</strong> <strong>3000</strong> transm<strong>it</strong>ter consists of two main components:<br />
— <strong>Dräger</strong> docking station<br />
This can be pre-installed anywhere and contains the electrical installation components.<br />
— The measuring un<strong>it</strong> <strong>Dräger</strong> <strong>Polytron</strong> <strong>3000</strong><br />
contains the electronics of the transm<strong>it</strong>ter.<br />
If the measuring un<strong>it</strong> is not f<strong>it</strong>ted immediately after installing the docking station, the<br />
latter should be covered w<strong>it</strong>h the raincover provided (dust and water protection) to<br />
protect against dust and splashing water.<br />
6
Installing the transm<strong>it</strong>ter<br />
Installing the docking station<br />
— If the transm<strong>it</strong>ter is to be installed in a Zone 2 explosion-hazard area, select a location<br />
w<strong>it</strong>h low exposure to mechanical risk.<br />
— Docking station is installed vertically (transm<strong>it</strong>ter w<strong>it</strong>h sensor facing down) in an<br />
area w<strong>it</strong>h low vibrations and stable temperatures – near the possible leak.<br />
— A space of at least 15 cm (6") must be maintained above the transm<strong>it</strong>ter for installation<br />
of the measuring un<strong>it</strong>.<br />
— A space of at least 10 cm (4") – preferably 30 cm (12") – must be maintained below<br />
the docking station to perm<strong>it</strong> access for maintenance.<br />
● Unpack the docking station.<br />
1 Remove raincover (protection against dust and splashing water).<br />

00123758_1.eps<br />
2 Remove the 4-pole terminal block (Part No. 83 16 268), keep <strong>it</strong> in a safe place and<br />
insert <strong>it</strong> again after completion of the installation work.<br />
● A drilling template is provided on page 51. The mounting holes are 66 ±4 mm (2.6<br />
± 0.16") apart.<br />
●<br />
Attention:<br />
Spacers (e.g. mounting bracket 68 09 772) must be used to prevent any<br />
twisting of the housing when installed on uneven surfaces.<br />
If the measuring un<strong>it</strong> is not to be mounted at this time:<br />
ref<strong>it</strong> the raincover (protection against dust and splashing water).<br />

Installing the transm<strong>it</strong>ter<br />
How to install the electrical connections<br />
— The electrical wiring may be laid and connected only by a qualified electrician,<br />
who must also comply w<strong>it</strong>h the appropriate regulations – a screened or unscreened<br />
cable (such as LiY, LiYCY) may be used.<br />
— Connection to central device w<strong>it</strong>h at least 2-wire cable, 0.5 to 2.5 mm 2 .<br />
— For currents of 0 to 22 mA, a DC voltage between 12.0 V DC and 30 V DC must<br />
be present at the transm<strong>it</strong>ter.<br />
Installing the 4 to 20 mA current loop on the transm<strong>it</strong>ter<br />
● F<strong>it</strong> 2-wire connecting cable in cable gland, cut to length and strip ends<br />
(approx. 80 mm / 3.15").<br />
● Shorten the shield (if installed) to prevent short-circu<strong>it</strong>ing:<br />
● Connect cable<br />
1 2-pin terminal for <strong>Polytron</strong> <strong>3000</strong> – check polar<strong>it</strong>y (marking in the docking station).<br />

— Ensure that the sensor is warmed up before <strong>it</strong> is calibrated. See the sensor data<br />
sheet for the warming-up time.<br />
— Only the zero point is checked if an oxygen sensor has been f<strong>it</strong>ted. The zero point<br />
of an oxygen sensor does not require calibration.<br />
— The transm<strong>it</strong>ter can be calibrated by the operator on s<strong>it</strong>e.<br />
— For cr<strong>it</strong>ical applications, the calibration intervals should be defined in accordance<br />
w<strong>it</strong>h the recommendations in EN 50073 1) , EN45544-4 2) and national regulations.<br />
Note the calibration sequence!<br />
● First check the zero point and correct <strong>it</strong> necessary, Immediately after this, check<br />
the sens<strong>it</strong>iv<strong>it</strong>y and adjust <strong>it</strong> as necessary.<br />
— Never calibrate the sens<strong>it</strong>iv<strong>it</strong>y before calibrating the zero point.<br />
— Zero gas and test gas: see the information in the sensor data sheet.<br />
Caution:<br />
Test gas must not be inhaled. Risk to health! Care must be taken about the<br />
