  • Page 3: For Your Safety

    For Your Safety For Your Safety Strictly follow these Instructions for Use Any use of this gas transmitter requires full understanding of the information pro- vided and strict adherence to the instructions given. The gas transmitter is only to be used for the purposes specified here. Maintenance Maintenance jobs may only be carried out by trained service personnel.

  • Page 4: Intended Use

    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.

  • Page 5: Explosion-Protection Approvals

    Explosion-Protection Approvals Explosion-Protection Approvals The explosion-protection approvals are valid for use of the device in gas/vapour-air mixtures of combustible gases and vapours under atmospheric conditions. The explosion-protection approvals are not valid for use in oxygen-enriched atmospheres. Unau- thorised opening of the enclosure invalidates the explosion-protection approval. —...

  • Page 6: Installing The Gas Transmitter

    Installing 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 the "Dräger PIR 3000 Installation Instructions" which are supplied with the gas transmitter. Mounting Location The protecting effect of the gas transmitter depends on the selection of the mount- ing location.

  • Page 7: Gas Exposure / Process Adapter (See "Accessories/Spare Parts

    Installing the Gas Transmitter Gas Exposure / Process Adapter ( see "Accessories/Spare parts" on page 28 ) For continuous flow operation of the gas transmitter, the calibration adapter can be replaced with an optional gas exposure / process adapter. — Suitable for flow rates between 1 and 3 L/min. —...

  • Page 8: Electrical Installation

    Installing 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, consult the responsible authorities before installing the device. We recommend a three-core, screened connection cable (mesh wire shield with a shielding factor of ≥ 80 %). Attention: Earth leakages on two phases can cause EMC problems.
  • Page 9 Installing 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 –...

  • Page 10: Commissioning

    Installing the Gas Transmitter Commissioning The Dräger PIR 3000 infrared gas transmitter is preconfigured and ready for use after installation. ● Deactivate the alarm call to the central device to avoid false alarms. ● When the supply voltage is applied, the gas transmitter automatically performs a self check (10 seconds), then automatically uses the factory-preset calibration (see page 11) and gas category.

  • Page 11: Operational Characteristics

    Zero gas and test gas are to be applied for functional check and calibration of the infrared gas transmitter Dräger PIR 3000. To this end, 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 —...
  • Page 12 (methane, propane, ethylene). The highest accuracy is achieved using test gas concentrations of 40 to 70 percent of the measurement span. The infrared gas transmitter Dräger PIR 3000 can also be used to measure other gases than mentioned above. For detailed information, refer to "Substitute Gas Cali- bration"...

  • Page 13: Configuration Of The Gas Transmitter Via Magnetic Pin

    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 28) as follows: — Automatic zerosetting. — Manual zero calibration of the output signal.

  • Page 15: Manual Span Calibration Of The Output Signal

    Operational Characteristics Manual Span Calibration of the Output Signal. The span calibration of the gas transmitter is only possible under the following condi- tions: — 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 approx.

  • Page 16: Substitute Gas Calibration 1)

    In this case, the gas transmitter returns to normal operation without displaying the span gas signal as confirmation. Substitute Gas Calibration The infrared gas transmitter Dräger PIR 3000 can also be used to measure other gases and vapours. The following table shows the required information (see also "Calibration" on page 11.

  • Page 17: Checking The Signal Transmission, Checking The Alarm Trigger And Displaying The Gas Category

    Operational Characteristics Checking the Signal Transmission, Checking the Alarm Trigger and Displaying the Gas Category The gas transmitter can create an output signal of 80 % of the full scale value, even without exposure to test gas. This 80% signal can be used to —...

  • Page 18: Changing The Gas Category

    Operational Characteristics — This signal is maintained for 30 seconds. The gas transmitter will then switch back to normal operation. — The central device display now matches the output signal of the gas transmitter. ATTENTION: Using the 80% signal to match central device and transmitter signal without test gas is no replacement for the span calibration of the gas warning system.
