  • Page 7: Product Description

    1 PRODUCT DESCRIPTION The GD10P has been designed with features that provide an effective response to the detection of gas hazards in a wide range of industrial environments from boiler plant rooms to offshore petrochemical installations. These infrared gas detectors differ from all other models, because they utilise silicon based solid- state infrared sources.

  • Page 11: Installation

    3 INSTALLATION The area in which the detector may be installed must be in accordance with the certification of the detector and in accordance with the standards of the appropriate authority in the country concerned 3.1 Positioning The detector should be mounted where gas leakage is most likely to occur. To detect methane, which is lighter than air, inside an enclosed area the detector should be mounted high in the area to be protected or immediately above potential leakage sites.

    3.4 Duct or pipe mounting If installed in a ventilation duct or pipe, the mounting arrangement and accessories shown in Figure 3 and Figure 4 should be used. The Duct Mounting Bracket shown in Figure 3 allows the GD10P to be positioned in the core of the airflow in wide ducts or pipes. Avoid direct light on lens and mirror if the GD10P is mounted without the Weather Protection.

  • Page 19: Operation

    Shows default factory settings. Can be configured via HART® terminal 5.2 HART® Interface 5.2.1 Introduction Simtronics GD10P detector supports HART® version 7. For proper operation between GD10P and the HART® communicator, a dedicated Device Descriptor (DD) should be loaded onto the communicator. If such DD is not present, the communicator will offer a proprietary generic interface, and the list of available functions may be limited and variable.
  • Page 20 5.2.2 Connection For access to the detectors HART® features, connect an industry standard HART® communicator as shown in the following figures depending on the type of analogue interface (source or sink). Note that for the HART® communication to work properly, a minimum loop resistance is required in the current loop.

  • Page 25: Maintenance

    6 MAINTENANCE The GD10P has no user adjustable parts. It is not recommended to open the GD10P, as this will change the internal atmosphere, and the initial calibration could be affected. Opening the GD10P voids all warranty offered at the time of sale. 6.1 Cleaning of optical lens/mirror Remove the weather protection by unscrewing the front cover plate (two screws), use a soft, clean tissue to rub off the contamination.

  • Page 26: Calibration Test

    The GD10 detector is calibrated and temperature tested in a controlled environment at the Simtronics factory. No further calibration is required during the life time of the product, as the zero point and calibration will stay inside the given tolerances. This implies that slight offsets from the zero point of 4.0mA (0%LEL) is to be expected and values up to 4.5mA at room...
  • Page 27 In some environments with excessive heat and/or vibration we have noticed that a higher percentage of the detectors develop an offset outside the specified tolerances. These detectors should normally be returned to the factory for service. An alternative is to do this re-zeroing on site with a dedicated hand held terminal, or HART®...
