Installing the transmitter
Preparing for installation
The performance and effectiveness of the entire system depends essentially
on the position chosen for installing the transmitter.
The following should be noted during installation:
— Local requirements and regulations governing the installation of gas meas-
uring systems.
— Relevant regulations concerning the connection and routing of electric pow-
er supply and signal lines.
— The full scope of environmental factors to which the transmitter may be ex-
posed (ambient conditions: see Technical data, page 87).
— Physical properties of the gas to be measured:
For gases with a density lower than that of air, the transmitter must be located above any possible leak or at the highest point at which large concentrations of gas may occur.
For gases and vapours with a density greater than that of air, the transmitter
must be located below a possible leak or at the lowest point at which such
gases and vapours may occur.
Installing the transmitter
— The specific uses (e.g. possible leaks, ventilation conditions, etc.).
— Accessibility for the necessary maintenance work (see Installation instruc-
tions for the Polytron docking station).
— All other factors and conditions which could have a negative effect on the
installation and operation of the system (such as vibrations or varying temperatures).
— We recommend installing a reflective shield if the unit is exposed to strong
sunlight.
— The transmitter must be installed vertically (sensor facing downwards).
— The transmitter has been tested with regard to its weather-resistance and
may be installed out of doors. Use of a splash guard is recommended to
protect the sensor from splashing water, dust and wind.
NOTE
In explosion-hazard areas:
Observe the national regulations concerning electrical equipment in explosion-hazard areas.
The Dräger Polytron 7000 transmitter consists of several components:
— Dräger docking station
This can be pre-installed anywhere and contains the electrical installation
components.
— The measuring unit Dräger Polytron 7000
contains the electronics of the transmitter.
If the measuring unit is not fitted immediately after installing the docking station, the latter should be covered with the raincover provided (dust and water
protection) to protect against dust and splashing water.

Connections between several transmitters and a control unit with HART multidrop connections
Each transmitter must first be put into service separately. Use the menu
item "Polling Address" to assign a different polling address in the range "1"
to "15" to each transmitter which is to be connected to the multidrop cable
(see page 70). It is best to assign sequential polling addresses, starting with
"1".
Installing the transmitters in areas subject to explosion hazards of zone
0 or zone 1
Depending on the supply unit, up to 7 transmitters can be connected to a 2-
wire or 3-wire cable.
The second cable gland is used for the cable to the next transmitter.
Install a safety barrier with the appropriate explosion protection approval
(category 1, 2 or Div. 1) between the transmitter and the control unit.
— Only safety barriers with the following characteristics may be used: Uo (Voc)
≤30 V, Io (Isc) ≤0.3 A, Po ≤700 mW.
— Take care that the maximum permissible capacitance and inductance of
connections to the safety barrier are not exceeded, also taking the cable
into account. The safety-related input parameters of the transmitter are: Ci
= 5 nF, Li = 50 µH.
— The safety barrier must be capable of transmitting the communications sig-
nals in both directions between the explosion-hazard area and the non-explosion-hazard area. Several manufacturers offer special SMART
transmitter supply units for this purpose.

Setting the switch for the backup battery
Check the position of the switch on the bottom of the unit.
This switch must be set to "on"; otherwise, the time, date and data saved in
the Datalogger and the Event Logger will be lost in the case of a power failure.
2 Insert the measuring unit about halfway up the docking station and slide it
in as far as it will go.
3 Lower the unit along the front edge of the docking station. About 5 mm be-
fore its hits the stop, the resistance will increase as the connector engages
with the socket on the printed circuit board.
NOTE
Check that the terminals in the docking station are correctly aligned if the
connector does not engage correctly!
Ensure that the front bottom of the measuring unit is flush with the bottom of
the Docking Station. Apply pressure to the measuring unit until it "clicks" into
place. If the fronts are not flush, the measuring unit is not completely sealed
and could get water inside the transmitter!
