The gas transmitter may only be installed by competent personnel (e.g. DrägerSer-vice) in compliance with the relevant regulations.

— The transmitter must be installed and started up as described in the "Dräger Po-lytron IR Installation Instructions" enclosed with every gas transmitter.

Installation site

— The transmitter should be mounted in the right position to ensure maximum pro-tection. Air must be able to circulate freely about the gas transmitter.

— The gas transmitter must be positioned as close as possible to the potential leak:

— The air flow conditions prevailing locally must be taken into account. The gas transmitter should be positioned in a location where the highest gas concentrati-on is to be expected.

— The gas transmitter must be positioned in such a way as to minimize the risk of mechanical damage.

— The gas transmitter must be readily accessible from all sides for maintenance pur-poses – a space of approx. 20 cm must be available at the hand terminal connec-tion and in front of the mirror holder!

Note the preferred position

— If a splash guard is used, the unit must be mounted vertically –

the connector for the hand terminal must point upward or downward!

— Flat or suspended installation is only permissible in the case of a gas transmitter without a splash guard –

There is a bigger risk of contamination during installation!

Water gathering on the optical surfaces can trigger a beam block.

— above the potential leak when monitoring gases or vapours lighter than air.— as near to the ground as possible when monitoring gases and vapours which

are heavier than air.

Electrical installation

The entire wiring must comply with the applicable local regulations governing the installation of electrical equipment in explosion-hazard areas. If in doubt, the official authority responsible should be consulted before installing the equipment.Devices with measuring function for explosion protection in accordance with Directive 94/9/EC, Annex II, 1.5.5 to 1.5.7, must be operated with a power supply which does not transmit power failures on the primary side lasting for less than 10 ms to the secondary side.

— Installation with 3-wire or multi-wire conductor. Recommendation: Use of a shielded line, shield braiding with a degree of co-verage

≥

80 %. Connection of the shield: to PE on the central controller and not on the transmitter side. In order to ensure correct operation of the gas transmitter, the impedance of the 4 to 20 mA signal loop must not exceed 500 ohm and must lie between 230 and 500 ohm in the case of HART-compatible smart loops. The resistance of the power sup-ply conductors must be sufficiently low to ensure a correct supply voltage at the gas transmitter.

The transmitter must not be supplied with power before the wiring has been completely connected and checked.

●

The terminal box must be electrically connected to ground.

●

Connect the gas transmitter – the connecting leads on the gas transmitter are colour-coded as follows:

●

Connect earthing conductor using an adequate terminal lug fastened to the provided screw, marked .

●

Check the electrical installation to ensure that all conductors have been connected correctly.

●

RS 485 wires are factory-insulated to meet "increased safety" requirements.Do not shorten white and blue wire if RS 485 is not used unless extra terminals are provided. Secure wires mechanically inside terminal box.

If the wiring has been installed in protective tubing:

●

Pour the seals for the protective tubing and allow to cure.

Wiring schematics:

Connection between several gas transmitters and a HART controller with Multidrop capability

●

The gas transmitters must first be started up separately. All gas transmitters to be operated on the Multidrop line must be con-figured with a different polling address between "1" and "15" (see Seite 36 »CONFIGURATION: COMMUNICATION: POL-LING ADDRESS«) via the menu item "Polling address". It is advisable to number the gas transmitters consecutively in ascending order, starting with "1".

Installation of the accessories

Dräger Polytron IR Splash guard

— The Dräger Polytron IR splash guard (Order No. 68 09 750) can be used to pro-tect the optical system in the gas transmitter against water and dust.

●

It must be installed in accordance with the installation instructions (supplied with every splash guard).

— The technical measuring properties of the gas transmitter are not affected by the splash guard. Only the response time may be increased slightly in stationary air.

Dräger Polytron IR Bump Test Adapter

— To test the transmitter Dräger Polytron IR (with splashguard) with a gas-/air-mix-ture of a concentration below the lower explosive limit (span gas), the Dräger Po-lytron IR bump test adapter (Order No. 68 10 985) can be used.

— As wind and convection will more or less cause a dilution, the gas concentration in the transmitter’s optical systems will always be lower than the concentration of the span gas. This is the reason why the bump test adapter is not suitable for ca-libration purposes.

●

It must be installed in accordance with the installation instructions (supplied with every bump test adapter).

— With the use of the bump test adapter neither the approvals nor the measurement performance is affected.

Dräger Polytron IR Flow cell

— The Dräger Polytron IR flow cell (Order No. 68 09 450) is used for function tests with a high test gas concentration. It can be used for gas transmitters with and wi-thout splash guard.

●

It must be installed in accordance with the installation instructions (supplied with every splash guard).

— The technical measuring properties of the gas transmitter are affected by the flow cell!

●

The zero point and sensitivity must always be calibrated after installation or de-installation (Seite 39 and Seite 40).

Dräger Polytron IR Process / gassing adapter

— Only for gas transmitters without splash guard and without flow cell.— The Dräger Polytron IR process / gassing adapter (Order No. 68 09 946) is used

to calibrate a gas transmitter orwhen operating the gas transmitter in pump mode, when the measured gas is sup-plied via an external pump.

●

Plug the process / gassing adapter onto the gas transmitter and secure it with two screws.

— The response time depends on the set volumetric flow rate.— Flow monitoring is required in pump mode.

Operation

Operation

System start-up

The Dräger Polytron IR gas transmitter is set to methane (type 334) or propane (type 340) on delivery and is immediately ready for use after installation.

● Deactivate the alarm trigger of the control system in order to avoid false alarms.● Switch on the power supply to the transmitter. The gas transmitter runs through a

self-test and then automatically operates with the calibration and mode set on de-livery.

● Check whether the calibration and configuration set on delivery are appropriate for the intended use of the transmitter – see "Configuring the gas transmitter", Seite 14.

● Check signal transmission to the controller and alarm triggering, see Seite 42 to Seite 44. National regulations may make it necessary to calibrate the zero point and sensitivity. Calibration procedure: see Seite 39 and Seite 40.

● Reactivate the alarm trigger to restore the system to its normal operating conditi-on.

— Parts of the transmitter housing are heated internally to prevent condensation of water on the mirror or window. For this reason, the surface temperature may increase by 10 to 20 oC.

Operation

14

Configuring the gas transmitter

The transmitter is configured as follows on delivery:

Type of gas and LEL concentration inputThe Dräger Polytron IR gas transmitter supports linearized and temperature-compensated display of up to 100 gases and vapours. The measured gas required for the application can be selected from the list stored in the software before first using the transmitter. The current selection of gases and vapours supported by the gas transmitter is shown in the table "Cross-sensitivi-ties", Seite 50. The procedure for setting the type of gas, measuring range and selecting the desired unit for output of the gas concentration is described on Seite 30.

Display of the measured concentration as a percentage of the lower explosion limit (LEL) is governed by conversion factors which vary from one region to another. The gas transmitter offers the possibility of selecting one of three categories more or less corresponding to the usual explosion limits in the USA, Europe and Germany (see Seite 29). The values stored and the associated categories can also be found in the table "Cross-sensitivities", Seite 50.

Calibration gasIn the case of many gases and vapours, calibration with the target gas is a considerable problem, since either a suitable calibra-tion gas is not available, the vapour pressure of the fluid at ambient temperature is too low, or using a calibration chamber in the field poses problems. Calibration using a substitute gas required detailed calculations in the past. Not every calibration gas con-centration was permissible. The Dräger Polytron IR gas transmitter is the first to support optional substitute calibration using any standard commercial test gases without additional conversion, provided both gases are on the list of gases on Seite 50.

A calibration gas which is different from the measured gas is used in order to calibrate the sensitivity. In calibration mode, the gas transmitter is first calibrated to the actual test gas concentration. Conversion of the calibration data to the measured gas then takes place automatically on exiting calibration mode. The specified measuring accuracy for the selected measured gas is ensured by the parameters and variables specific to the gas stored in the gas transmitter.

Warning status display at the analog outputThe following configurations are available:

Operation

Beam block warning (Patented by Dräger Safety)Although the Dräger Polytron IR gas transmitter has effective devices to protect the optical system, gradual fouling of the beam path under severe conditions of use cannot be ruled out altogether. To prevent interference with measurement due to heavy con-tamination, the Dräger Polytron IR gas transmitter has been equipped with a system which gives advance warning of fouling of the beam path before any interference occurs, without causing a complete breakdown in measurement. The beam block warning can be activated for this purpose (configuration 2 in the table).If a build-up of dirt causes the light intensity at the inlet to the optical measuring unit to fall below a critical value, such that suf-ficient stability of the measuring signal is no longer guaranteed, the gas transmitter emits a constant current of 2 mA at the ana-log interface when the beam block warning is activated. Since the residual light intensity is still high enough to guarantee reliable detection of alarm states above 15 % LEL, measurement of the current gas concentration continues in the background. Any hazard arising due to explosive gases above a concentration of 15 % LEL is still detected. The transmitter switches itself back to measuring mode and reliably displays the hazard at the analog output or digital.This system allows scheduled servicing to be planned and controlled more efficiently, as immediate access / cleaning is not necessary. If the contamination reaches such a degree that reliable detection of gas concentrations above 15 % LEL is no longer possible, a fault status is reported with the associated 1 mA analog signal or digital. In this case, the system is no longer ready for measurement.

Other analog displays when a warning occursA second way of displaying a warning status at the analog output is the option of activating the warning function described on Seite 32 (configuration 3 in the table). In this case, a warning is displayed with output of a 3 mA level for 0.7 second. This is repeated every 10 seconds. Besides the general warnings, this function also indicates increased contamination which may cause the signal to become unstable. Heavier fouling is indicated by emitting an error status at 1 mA as described above.

A combination of the two analog warnings described above is also possible (configuration 4 in the table). Whereas general warnings are then indicated by the level of 3 mA for 0.7 seconds, in this case a beam block warning is treated separately and indicated in analog form by a 2 mA signal.

Operation

16

Measurement

— The gas transmitter generates a 4 to 20 mA signal proportional to the measured gas concentration when configured for analog transmission.

— The following can be used for digital processing of the gas transmitter data:

Hand terminal ABB, model 691 HT with Dräger Polytron IR adapter lead – Order No. 83 15 437

or

Dräger Controller Regard HART card1) – Order No. 42 05 900, installed in a Regard system

or

every HART or RS 485 communications tool using the Dräger HART protocol1).

Numerous internal functions are regularly self-tested by the gas transmitter. A warning or fault signal is immediately output by the gas transmitter whenever a devia-tion from normal operation is detected.

POLLING ADDRESS

(Configuring the polling address)The gas transmitter is configured for analog operation (4 to 20 mA) or Multidrop operation via the polling address. Analog mode (4 to 20 mA) is activated by setting the polling address " 0 ". The polling address must be set to a value between " 1 " and " 15 " for Multidrop operation. In this case, the analog interface is deactivated and set to a constant current of approx. 1 mA. All gas transmitters connected to a single line must be configured with different polling addresses so that the controller can poll the unique identifier (unique HART address) via the HART command #0. It is advisable to assign polling addresses in consecutive ascending order starting with " 1 ".The setting corresponds to the HART command #6 ("Write polling address").

Select the function:● Press » F1 « to invoke the function. The set momentary configuration is displayed

CALIBRATE SENSOR

(Perform calibration)This submenu contains all the functions needed for calibrating the gas transmitter.

The gas transmitter must have warmed up before starting calibration !Calibration settings should remain unchanged while the gas transmitter warms up, otherwise the measuring accuracy will be impaired.If calibration is performed during the warm-up phase, it must be repeated when the gas transmitter has warmed up.

If the gas transmitter is operated with a flow cell (accessory part, see Seite 10), the flow cell must be installed before the transmitter is calibrated.

Note the sequence of steps !First check the zero point. If it has to be corrected, check the sensitivity immediately afterwards and adjust it if necessaryNever calibrate the sensitivity before the zero point.

If unforeseen faults occur during the calibration procedure, press » « to abort calibration without changing the former calibration values.

The Dräger Polytron IR gas transmitter is a transducer for measuring the concentra-tion of hydrocarbons in the atmosphere by absorbing infrared radiation.

The infrared technology differs from other processes in the following ways:— Unambiguous indication of concentrations above the lower explosion limit,— Less maintenance effort due to better long-term stability,— Fail-safe,— Insensitive to the rate of flow,— Insensitive to polymerizing and corrosive substances and catalyst poisons,— Unrestricted sensitivity in low-oxygen and oxygen-free mixtures,— No detection of ethine, hydrogen and carbon disulphide.

Microprocessor technology permits:— Identification of equipment faults and warnings via the display and current inter-

face,— Special calibration mode to suppress alarms in the controller during maintenance

work (one-man calibration),— Individual linearization of the display for all measured gases,— Temperature compensation,— Unit of measurement can be selected for the display,— Freely selectable measuring range.

The ambient air to be monitored is entrained into the cuvette by a thermally induced updraft.An infrared emitter L1 generates a wideband modulated beam (visible components can be seen to flash). The beam emerges from the housing through an exit aperture and passes through the cuvette twice. The plane-parallel mirror S reflects the beam which is diverted to the detectors D1 and D2 in the optical module. The cuvette is heated to prevent condensation of the moisture contained in the atmosphere.

The beam is absorbed at the measuring wavelength on account of hydrocarbon com-ponents in the atmosphere, thus causing the signal at detector D1 to decrease. The stability of the zero point is guaranteed by a reference detector D2 which compensa-tes the effects of dirt on the mirror and window, as well as fluctuations in the inten-sity of the infrared emitter.

A second internal emitter L2 compensates thermal drifts and ageing by the two detectors or lamps. Together, these two compensation processes ensure maximum stability.
