For Your Safety For Your Safety Strictly follow the Instructions for Use Any use of this gas transmitter requires a full understanding and strict adherence to these instructions. This gas transmitter is only to be used for the purposes specified here. Maintenance Only trained service personnel may repair the gas transmitter.
Intended Use Intended Use The Dräger PIR 3000 infrared gas transmitter is a device used for stationary, contin- uous monitoring of the concentration of carburetted, combustible gases and vapours in the ambient air. The gas transmitter is preconfigured for the gases methane, propane and ethylene.
Explosion-Protection Approvals Explosion-Protection Approvals The explosion-protection approvals are valid for use of the device in gas/vapour-air mixture of combustible gases and vapours under atmospheric conditions. The explosion-protection approvals are not valid for use in oxygen enriched atmospheres. In case of unauthorised opening of the enclosure, the explosion-protection approval is forfeit. —...
How to Install the Gas Transmitter Only trained service personnel (e.g. of Dräger Safety) may install the gas transmitter under observation of relevant regulations. Installation and commissioning are described in "Dräger PIR 3000 Installation Instructions", supplied with the gas transmitter. Mounting Location The protecting effect of the gas transmitter depends on the selection of the mount- ing location.
How to Install the Gas Transmitter Gas Exposure / Process Adapter ( see "Accessories/Spare parts" on page 27 ) Instead of the calibration adapter, a gas exposure / process adapter can optionally be fitted to the gas transmitter for continuous flow operation. —...
How to Install the Gas Transmitter Electrical Installation The entire wiring must correspond with applicable local regulations concerning the installation of electrical devices in potentially explosive atmospheres. In case of doubt, the official responsible authorities are to be consulted prior to installation of the device. We recommend a three-core, screened connection cable (mesh wire shield with a shielding factor of ≥...

How to Install the Gas Transmitter — The leads between central device and gas transmitter must have a sufficiently low resistance to ensure the correct supply voltage at the gas transmitter. The maxi- mum resistance per core is calculated as follows: 2.5 x U –...
How to Install the Gas Transmitter Commissioning The Dräger PIR 3000 infrared gas transmitter is preconfigured and ready for use after installation. ● To avoid false alarms, the alarm call to the central device is to be deactivated. ● When the supply voltage is applied, the gas transmitter automatically performs a self check (10 seconds).
Operational Characteristics Operational Characteristics The gas transmitter generates an output signal which is proportional to the meas- ured gas concentration. The factor of proportionality between displayed value and the measured gas concentration is determined by the span calibration of the gas transmitter (see "Manual span calibration of the output signal."...
Zero gas and test gas are to be applied for functional check and calibration of the infrared gas transmitter Dräger PIR 3000. For this, the gas is applied either with — the calibration adapter in connection with the splash guard (see page 5, part of the scope of delivery) or —...
Operational Characteristics Configuration of the Gas Transmitter via Magnetic Pin A magnetic pin can be used to change the settings of the Dräger PIR 3000 infrared gas transmitter (see "Accessories/Spare parts" on page 27) as follows: — Automatic zerosetting — Manual zero calibration of the output signal.
Operational Characteristics Manual zero calibration of the output signal. ● Deactivate alarm activation of the central device. 1 Expose the gas transmitter to nitrogen, synthetic air, resp. fresh air via calibration adapter and wait until measurement value stabilises. 2 Place the magnetic pin onto the transmitter surface area marked by the " "...
Operational Characteristics Manual span calibration of the output signal. The span calibration of the gas transmitter is only possible under the following conditions: — The last zero calibration of the device was less than one hour ago. — The span gas concentration is sufficiently high to effect a display on the device of at least 20% LEL.
Operational Characteristics ATTENTION: The calibration is automatically terminated and new calibration parameters are not saved if the gas concentration measured by the gas transmitter changes during the calibration procedure (e.g. because the calibration gas cylinder fell empty during the calibration procedure). In this case, the gas transmitter returns to normal operation without displaying the span gas signal as confirmation.
Operational Characteristics ● Remove the magnetic pin. The gas transmitter changes to an output signal which displays the currently set target gas category according the following table: target gas category Display [%LEL] methane propane ethylene — This signal is maintained for 30 seconds. The gas transmitter will then switch back to normal operation.

Maintenance Maintenance At regular intervals, that are to be determined by the persons responsible for the gas warning system while taking local regulations into account: ● Visual inspection to look for damage and contamination. Special attention is re- quired for gas entrance to the gas transmitter. Anything that blocks the gas en- trance to the transmitter, e.g.

Technical Data Cross Sensitivities The gas transmitter measures the concentration of hydrocarbons. Factory-preset calibration parameters are available for meth- ane, propane and ethylene gases. However, other hydrocarbons can also be measured. The following text has examples of typi- cal display values for some types of hydrocarbon, with the gas transmitter calibrated in the respectively stated target gas category.
Description of Design Description of Design The Dräger PIR 3000 infrared gas transmitter is a gas transmitter designed to deter- mine the concentration of gases and vapours in the ambient air. The principle of measurement is based on the concentration-dependent absorption of infrared radiation in measured gases.
