  • Page 10: 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 11 Failure to follow this caution can result in minor or moderate injury. 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 12 3 Installation A stainless steel mounting plate is included with either junction box to ensure that there is sufficient clearance from the installed surface (see Figure 5 and Figure 6 1.

  • Page 15 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.

    Transient Fault conditions will be automatically cleared when the unit recovers from the fault condition. MSA recommends verifying proper response to changes in mA outputs by using the "Enter Fixed Current Mode" command described in the PrimaX IR Link Help Guide to check the four fault conditions noted with a * above. These checks should be done at every calibration phase.

  • Page 22 4 Start-up and Calibration The unit must see gas within 30 seconds after the span symbol starts to flash or a calibration fault may occur. The initial 30 seconds are intended to give the user time to apply gas to the sensor. During this time, the user can abort the Span process by removing the calibration cap.
