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.

page 22. — If digital communication in accordance with HART is to be used, the load

resistance of the supply unit must lie between 230 and 500 Ω.

— The permissible cable lengths are shown in the tables on page 21 to

page 22. In each case, use the line marked "Number of transmitters = 1".

Electrical connections

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.

The assembly direction of the pump adapter is determined by the gas flow direction between pump and sensor: — Connectors for intake and exhaust air point to the left, the symbol is vis-

ible from the front; the pump is positioned in front of the sensor in gas flow direction; the sensor is positioned on the positive pressure side of the pump. This is the preferred operating mode for all sensors.

— Connectors for intake and exhaust air point to the right, the symbol is

visible from the front; the pump is positioned behind the sensor in gas flow direction; the sensor is positioned on the negative pressure side of the pump. This operating mode should only be selected for special reasons.

CAUTION

This operating mode is not permissible for DrägerSensor O2 LS (6809630) and DrägerSensor O

 Insert the pump adapter sleeves into the holes on the underside of the

(6809720)!

docking station. The seal slides over the sensor.

1 Turn the securing ring clockwise until the pump adapter is secure.

Notes on installation of the inlet line

The material selected for the inlet hose or inlet pipe and the length of the inlet line will affect the reaction time of the measured signal. In the worst cases, reactions with the selected material, or absorption in this material, will prevent a measurable gas concentration from reaching the sensor. — Please contact your Dräger sales partner for choice on suitable selection of

tubing/hose.

— Maximum permissible pressure difference between flow inlet and the envi-

ronment of the transmitter: 50 mbar

— The pressure difference between the flow inlet and the environment of the

transmitter can cause an additional measurement error.

CAUTION

In order to check for leaks, we recommend that you measure the flow at the inlet point and behind the transmitter before using the pump module for the first time and every six months thereafter.

Do not block the lower gas line of the pump adapter. This can damage the gas sensor.

Maintenance

Maintenance intervals

Before starting operation:

 Check the calibration, see page 44.  Check the transmission of signals to the control unit and the triggering of

alarms, page 74.

At regular intervals,

to be defined by the person responsible for the gas warning installation:

 Check the transmission of signals to the control unit and the triggering of

alarms, page 74.

If a selective filter specific to the sensor is being used:

 Replace the selective filter –

See the related operating instructions for the sensor for details of the capacity of the selective filter being used.

Maintenance

At regular intervals defined in accordance with the sensor being used by the person responsible for the gas warning system:

 Calibrate the sensor, see page 44.

The interval for regular calibration depends on the sensor being used and on the operating conditions. The transmitter calculates, from the selected calibration interval (see page 56), when the next calibration is due. Specific calibration data for the sensor, see the operating instructions for the sensor.

Every six months:

 Inspection by specialists.

The inspection intervals must be established in each individual case and shortened if necessary, depending on technical safety considerations, engineering conditions and the technical requirements of the equipment. We recommend that a service agreement be concluded with DrägerService and that repairs also be carried out by them.

When using the pump module:

 In order to check for leaks, measure the flow at the inlet point and behind

the transmitter.

As required:

 Replace sensor, page 46.

Calibrating the unit

— Ensure that the sensor is warmed up before it is calibrated. See the sensor

data sheet for the warming-up time. — For some sensors (such as oxygen sensors) the function » zero-point

calibration « is simply a test of the sensor function. The zero point is not ac-

tually calibrated since this is not necessary for these sensors.

— For critical applications, the calibration intervals should be defined in ac-

cordance with the recommendations in EN 500731), EN45544-42) and na-

tional regulations.

Note the calibration sequence!

 First check the zero point and calibrate it if necessary, immediately after

this, check the sensitivity and adjust it as necessary. — Never calibrate the sensitivity before calibrating the zero point.

— Calibration cannot be carried out if the date and time are not set.

 Setting the date and the time, page 67.

— Calibration menu, page 58 to page 59.

— Zero gas and test gas: see the information in the sensor data sheet and on

the pages 118 to 121.

CAUTION

Test gas must not be inhaled. Risk to health! Care must be taken about

the risks which can arise when using test gas; hazard instructions and safety advice must be observed. For details, see appropriate DIN Safety Data Sheets.

Calibrating with test gas

 Use a test-gas cylinder with pressure-reduction valve (a stainless-steel

pressure reduction valve for aggressive gases). Observe the information in

the sensor data sheet. 1 Mount a calibration adapter Part No. 68 06 978 (with two hose connectors)

on the Polytron 7000.

 Vent the test gas leaving the adapter into a fume cupboard or into the open

air (with a hose connected to the second connector on the calibration

adapter).

EN 50073 – Guidelines for selection, installation, use and maintenance of devices for

the detection and measurement of flammable gases and oxygen.

 Remove the short-circuit strap from the sensor (if it is fitted).  There is a coded connector on the back of the sensor. Place the sensor in

the opening with the connector at the back and the Dräger logo at the front.

Before plugging the connector in the socket, ensure that they are identically

coded. Incorrect connection can damage the sensor! 1 Secure sensor in transmitter with bayonet ring.

 It is possible to mark the transmitter with the label enclosed in the packag-

ing. It will then be easy to identify the type of gas for which the transmitter

is intended if there is a mains failure.

 Check sensor function.

— If an identical sensor (sensor with the same Part No.) was previously in-

stalled, the complete configuration of the transmitter remains unchanged.

Otherwise, the transmitter is configured with the default values (see the op-

erating instructions for the sensor).

Submenu » Communication «

The submenu » Communication « permits various settings to by made for the interfaces.

HART interface

This group contains the setting functions for the HART interface.

– Polling address

The polling address configures the transmitter either for the analogue mode (4 to 20 mA) or the multidrop mode. Setting the polling address to " 0 " enables the analogue mode (4 to 20 mA). To enter multidrop mode, the polling address must be set to a value in the range from " 1 " to " 15 ", which disables the analogue interface and freezes it to a constant current of approx. 3 mA. In order to enable the central controller to request the unique identifier (unambiguous HART address) using HART command #0, all transmitters located on one cable trunk need to be configured with a different polling address. It is best to assign sequential polling addresses, starting with "1". This setting corresponds to the HART command #6 ("Write Polling Address").

 Select the menu items » Settings «, » Communication «, » Hart interface «

and » Polling address « in this order, pressing the » « key after each selection.

 Use the » « and » « keys to set each position of the polling address

and press the » « key to confirm the setting.

 Press the » « key to confirm the complete polling address.

– Unique Identifier

This function can be used to read out the unique identifier (unique HART address), which must be known for the addressing in almost all HART commands. However, knowledge of the unique identifier is necessary only for systems which are not able to read out the unique identifier with the HART command #0 in the short-frame format or the HART command #11. The display corresponds to the address returned by the HART command #0 ("Read Unique Identifier") or #11 ("Read Unique Identifier associated with Tag").

 Select the menu items » Settings «, » Communication «, » Hart interface «

and » Identifier « in this order, pressing the » « key after each selection.

— The unique identifier will be displayed.

– Tag

The tag may be used to mark a specific transmitter. It can comprise up to 8 alphanumeric characters. It can also serve as an address, in order to read the unique identifier using HART command #11 ("Read Unique Identifier associated with Tag"), from the transmitter, even if the polling address is unknown. This presumes that an unambiguous tag has been configured before.

 Select the menu items » Settings «, » Communication «, » Hart interface «

Submenu » Sensor «

The submenu » Sensor « can be used to make various settings for the installed sensor.

Change sensor

— This function can be used to change a sensor while the unit is running with-

out sending a fault alarm to the control unit. It also ensures that all sensor

data currently in the microprocessor can be saved to the EEPROM of the

sensor before the sensor plug is disconnected. — In principle, a sensor can be replaced at any time. However, for technical

safety reasons, a fault alarm will be activated until a new sensor is connect-

ed, in case a sensor is disconnected accidentally.

 Select the menu items » Settings «, » Sensor « and » Change sensor « in

this order, pressing the » « key after each selection. — The maintenance signal is transmitted on the analogue interface, and the

display reads: » Please remove sensor«.

 Remove the old sensor and plug in the new one (see page 46).

When the new sensor has been installed:

 The message » Loading database, please wait « is displayed.

When the sensor data have been loaded: — The message » Database is loaded « is displayed.

 Select » Back to menu « and press the » « key.

— The maintenance signal on the analogue interface remains until the sensor

operates normally.

The duration of the warming-up period depends on the type of sensor and

its history. If, for example, the sensor had already been warmed up on an-

other transmitter and it was disconnected only for a short time, the warm-

ing-up period may be shorter than that shown in the operating instructions

for the sensor.

See the operating instructions for the sensor for the maximum warming-up

period.

If the old sensor is replaced with an identical sensor (with the same Part

No.), the configuration of the transmitters (gas type, measuring range, cal-

ibration gas, calibration interval) remains unchanged.

Otherwise, the default values for the sensor (see the operating instructions

for the sensor) are used by the transmitter if the sensor-lock function

(page 77) is disabled.
