  • Page 5: Safety Regulations

    Safety Regulations Correct Use The PrimaX IR Gas Monitor - referred to hereafter as device - is a fixed infrared combustible gas detector. It is suitable for outdoor and indoor applications, e.g. offshore industry, chemical and petro- chemical industry, water and sewage industry.

  • Page 6: Safety And Precautionary Measures To Be Adopted

    • Do not mount the device in direct sunlight, since this may cause it to overheat. A stainless steel sunshield is available for the PrimaX IR Gas Monitor to protect it from extreme environments. • The only absolute method to ensure proper overall operation of the device is to check it with a known concentration of the gas for which it has been calibrated.

  • Page 8: Description

    This device does not provide a visual display of information. The gas level and basic device status are available via the 4-20 mA output signal. Other detailed device status is available via the HART signal. Details about this interface can be found in the PrimaX IR HART Specification located on the product CD shipped with the device.

  • Page 11: Installation

    If a junction box is not being used, mount the device on a support by using suitable hardware (not supplied), and in accordance with local regulatory requirements. MSA recommends mounting the sensor horizontally. Horizontal mounting will help prevent the build-up of particulate or liquid matter on the monitor's optical surfaces.

  • Page 12: Optional Junction Box Instructions

    Applying force to the legs can permanently damage the monitor. MSA recommends that the device’s environmental guard should be installed on the unit at all times. If the device is to be operated without the guard, frequent checks must be made to ensure particulate or liquid matter has not collected on the windows.

  • Page 15: External Controllers

    The device can be connected to any device capable of accepting a 4 - 20 mA sourcing analog signal. For FM approved systems, the connecting device must have latching alarms with manual reset. Ensure that your controller can read all signals. Check the MSA website www.MSAsafety.com for available controllers.

Fig. 19 Remove Environmental Guard Place an opaque object (piece of paper, two fingers, etc.) between the light source window and the mirror to completely obscure the light path for two to three seconds (see Fig. 20). If the opaque object is left in the light path for longer than 10 seconds, an Obscuration fault will be set on the mA output (see chapter 4.1).

  • Page 30: Environmental Guard Cleaning

    Maintenance Although both windows are made of a highly durable material that is not easily scratched, avoid exces- sive pressure when cleaning them. Clean, cotton tipped applicators are recommended to remove material collected on the windows. Use a dry applicator or one moistened with distilled water to wipe the window and remove dust. Use an additional clean, dry applicator to remove any residual water.
