  • Page 5: Information

    This manual is for use with the Salwico GD range transmitters only. The Start-up/Surge/In rush current is dependant on the type of power supply used. The typical start-up current for Salwico GD is less than 800mA. Measure the start-up current using the specific power supply before installation to ensure suitability for your application.

    Salwico GD Technical Manual 5100516-00A Rev:A01 6.4 Cabling Caution: All unused and used cable/conduit entries must be sealed with a suitable certified sealing plug and cable gland. The use of industrial grade, suitably armoured field cable is recommended. For example, screened 3 cores (plus screen 90% coverage), suitably mechanically protected copper cable with a suitable M20 explosion-proof gland, or ¾” NPT steel conduit, with 0.5 to 2.5 mm2 (20 to 13 AWG) conductors.
  • Page 19: Ground Terminal Wiring

    Salwico GD Technical Manual 5100516-00A Rev:A01 The Earth Screen of the field cable should be “tied to Earth” or connected to Ground at one point only. It is common practise to adopt a STAR EARTH connection regime where all instrumentation Screens are connected at one common point. The Screen at the other end of the cable should be “parked” or terminated into a blank terminal.

    “cross calibration” using another hydrocarbon gas/air mixture. When the Salwico GD Combustible LEL sensor is to be calibrated with a gas which is different to the gas or vapour to be detected, the following cross calibration procedure may be followed: Caution: Where the user calibrates any sensor using a different gas, responsibility for identifying and recording calibration rests with the user.

Star Rating of Gases To cross calibrate the Salwico GD flammable gas detector: (1) Obtain the star rating for both the calibration test gas and the gas to be detected from Table 14 (2) These values may then be used in Table 15 to obtain the required calibration span setting when a 50% LEL test gas is applied to the detector.

Since catalytic sensors require oxygen for correct operation, a mixture of gas in air should always be used for calibration purposes. 2. Assuming average performance of the sensor, the sensitivity information in Tables 14 To 16 is normally accurate to + or - 30%.
