    MAN0530 Issue 10 - 11/09 Searchline Excel 2104M0506 1. INTRODUCTION Searchline Excel is a hydrocarbon gas detection system that is available in two versions: • Searchline Excel Open-Path Gas Detector • Searchline Excel Cross-Duct Gas Detector For information regarding the Cross-Duct Excel contact Honeywell Analytics. Searchline Excel Open-Path Gas Detector (OPGD) consists of a Transmitter unit that sends an infrared beam to a Receiver unit up to 200 metres away, and can be located where a flammable hydrocarbon gas cloud is likely to occur.

    MAN0530 Issue 10 - 11/09 Searchline Excel 2104M0506 2. OVERVIEW INTRODUCTION Each type of Searchline Excel gas detector consists of two units, a Transmitter and a Receiver. This separate Transmitter/Receiver configuration provides the most reliable basis for open path gas detection. DVC100(M) MK2 or DX100(M) (or other junction box) Mounting plate...
  • Page 9: Transmitter

    Long Range 120 – 200m (390ft – 650ft) When designing an installation for Searchline Excel it is important that the correct range of the gas detector for each path to be monitored is selected and specified. The Transmitter and Receiver are each mounted upon robust, adjustable mounting brackets. These brackets bolt to a mounting plate, which is designed to accommodate a variety of junction boxes, accessories and mechanical mounting configurations. The small size and flexibility of...
  • Page 10: Receiver

    (GND). RECEIVER The Searchline Excel Receiver collects infrared radiation from the Transmitter and performs measurements to enable hydrocarbon gases in the beam path to be detected. Infrared radiation is collected by a single, silicon lens, which is common to both the sample and reference measurement channels.
  • Page 11 2. OVERVIEW 417mm (SR) 160mm The solid state, photovoltaic detectors used in Searchline Excel provide an exceptional dynamic range and superb temperature and long term stability. These features contribute strongly to the solar immunity and stability of Searchline Excel. The Receiver contains all of the electronics necessary to amplify, condition and process the signals received by the infrared detectors.

    Preferably, the case (internally connected to the green/yellow GND wire) should be connected to a low noise instrument (clean) earth. See also para e. below. In order to facilitate electrical isolation of the Searchline Excel from a noisy earth an isolation kit is supplied. This kit should be fitted as standard unless local regulations forbid this.
  • Page 19 MAN0530 Issue 10 - 11/09 Searchline Excel 2104M0506 3. INSTALLATION AND OPERATION All electrical equipment connected to the gas detector should comply with EN61000-6- 3:2007 and EN61000-6-2:2005. The 24V supply should be free from large transients and fluctuations. The field cabling conductors should have sufficient cross sectional area to ensure that the minimum supply voltage applied to the gas detector is 18V at a current of 420mA.

    Do not attempt to view the Sun through the optical telescope. 3.7.1 General In order to avoid unnecessary problems, alignment and commissioning of Searchline Excel gas detectors should only be performed by personnel trained by Honeywell Analytics. To ensure optimum performance the gas detector Transmitter and Receiver units must be accurately aligned with a clear line of sight between them.
  • Page 34 MAN0530 Issue 10 - 11/09 Searchline Excel 2104M0506 3. INSTALLATION AND OPERATION Fine adjustment is then achieved by means of mounting bracket and pivot block grubscrews which move levers on the adjustment clamps, fitted to the pivot block and unit studs, and hence the unit. After initial mechanical setup the units are powered up and the mechanical alignment can be optimised and verified electronically by means of the associated Handheld Interrogator linked to the Receiver.

    3.7.5. 3.8 SYSTEM CONTROLLER CALIBRATION This procedure is used to set up the system controller using the Searchline Excel gas detector. A chosen fixed output signal is sent from the Excel gas detector to the system controller allowing calibration of the 0 - 100% scale of the controller without having to use gas. The steps use procedures described in the previous section.

Such sources could include radio/radar transmission antennae, high voltage switch-gear, large electrical generators/motors etc. Searchline Excel is extremely immune to RFI/EMI, complying with the most stringent requirements specified in EN50270. It is therefore more likely that the field cabling will pick up interference directly on the 4 - 20mA and 0V connections and that this will affect the reading received at the control room.
