OperationOperationSystem start-upThe 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 aself-test and then automatically operates with the calibration and mode set on delivery.● Check whether the calibration and configuration set on delivery are appropriatefor 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 toSeite 44. National regulations may make it necessary to calibrate the zero pointand sensitivity. Calibration procedure: see Seite 39 and Seite 40.● Reactivate the alarm trigger to restore the system to its normal operating condition.— Parts of the transmitter housing are heated internally to prevent condensation ofwater on the mirror or window. For this reason, the surface temperature mayincrease by 10 to 20 o C.13

The measured gas required for the application can be selected from the list stored in the software before first using thetransmitter. The current selection of gases and vapours supported by the gas transmitter is shown in the table "Cross-sensitivities",Seite 50. The procedure for setting the type of gas, measuring range and selecting the desired unit for output of the gasconcentration is described on Seite 30.Display of the measured concentration as a percentage of the lower explosion limit (LEL) is governed by conversion factorswhich vary from one region to another. The gas transmitter offers the possibility of selecting one of three categories more orless corresponding to the usual explosion limits in the USA, Europe and Germany (see Seite 29). The values stored and theassociated 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 calibrationgas is not available, the vapour pressure of the fluid at ambient temperature is too low, or using a calibration chamber in thefield poses problems. Calibration using a substitute gas required detailed calculations in the past. Not every calibration gas concentrationwas permissible. The Dräger Polytron IR gas transmitter is the first to support optional substitute calibration using anystandard 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, thegas transmitter is first calibrated to the actual test gas concentration. Conversion of the calibration data to the measured gasthen takes place automatically on exiting calibration mode. The specified measuring accuracy for the selected measured gasis 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:Configuration Beam block warning General warning1 Off Off2 On Off3 Off On4 On On14

OperationBeam 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 beampath under severe conditions of use cannot be ruled out altogether. To prevent interference with measurement due to heavy contamination,the Dräger Polytron IR gas transmitter has been equipped with a system which gives advance warning of fouling ofthe beam path before any interference occurs, without causing a complete breakdown in measurement. The beam block warningcan 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 sufficientstability of the measuring signal is no longer guaranteed, the gas transmitter emits a constant current of 2 mA at the analoginterface when the beam block warning is activated. Since the residual light intensity is still high enough to guarantee reliabledetection of alarm states above 15 % LEL, measurement of the current gas concentration continues in the background. Anyhazard arising due to explosive gases above a concentration of 15 % LEL is still detected. The transmitter switches itself back tomeasuring 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 notnecessary. If the contamination reaches such a degree that reliable detection of gas concentrations above 15 % LEL is no longerpossible, a fault status is reported with the associated 1 mA analog signal or digital. In this case, the system is no longer readyfor 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 onSeite 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 isrepeated every 10 seconds. Besides the general warnings, this function also indicates increased contamination which maycause 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 generalwarnings are then indicated by the level of 3 mA for 0.7 seconds, in this case a beam block warning is treated separately andindicated in analog form by a 2 mA signal.15

Design and principle of operationDesign and principle of operationThe Dräger Polytron IR gas transmitter is a transducer for measuring the concentrationof 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 interface,— Special calibration mode to suppress alarms in the controller during maintenancework (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 inducedupdraft.An infrared emitter L1 generates a wideband modulated beam (visible componentscan be seen to flash). The beam emerges from the housing through an exit apertureand passes through the cuvette twice. The plane-parallel mirror S reflects the beamwhich is diverted to the detectors D1 and D2 in the optical module. The cuvette isheated to prevent condensation of the moisture contained in the atmosphere.SThe beam is absorbed at the measuring wavelength on account of hydrocarbon componentsin the atmosphere, thus causing the signal at detector D1 to decrease. Thestability of the zero point is guaranteed by a reference detector D2 which compensatesthe effects of dirt on the mirror and window, as well as fluctuations in the intensityof the infrared emitter.A second internal emitter L2 compensates thermal drifts and ageing by the twodetectors or lamps. Together, these two compensation processes ensure maximumstability.L1L2D2D101123592_4.eps53

CSA approvalCSA approvalThe transmitter has successfully been tested by CSA at ambient temperatures down to –55 o C, exceeding the minimum ambient temperature of–40 o C per CSA performance standard C22.2 No. 152. As this ambient temperature is beyond the scope of the standard, a greater tolerancethan ±10 %LEL is allowed. During test, the deviation of the instrument at –55 o C was +13 %LEL with 50 %LEL gas applied.66
