    SERIES 5000 EQUIPMENT DETAIL General Description The 5000 Series system described here comprises two primary elements :- Sensor Unit - Model 5410  Air Supply / Blower Unit  The Sensor is located above the materials transit path (e.g. conveyor) by means of the adjustable mounting bracket and aligned such that the monitored hazard passes through the unit’s field of view.
  • Page 5 The unit can also be employed with the two wire connection to a remote Patol signal relay module. Refer to figures 4 & 5.

  • Page 6: Specification

    SERIES 5000 Sensor Arrangement A dual detector channel sensing module is located within an ABS housing which is mounted by means of an adjustable bracket, permitting alignment in both vertical and horizontal planes. The outer housing is equipped with an air hose spigot. The signal cable enters through glands in both outer housing and inner module and is terminated at screw terminals.

  • Page 12 SERIES 5000 Purge Air Supply The 5410 Sensor unit is equipped with a spigot for connection to a flexible hose. The air supply must be capable of delivering at least 5.0 ltrs/sec at this connection and maintain a minimum pressure of 4.0 mBar (1.6”...
  • Page 13 The SIL switch must be returned to the setting of 4.2 before proceeding to 4.3.3. 4.3.3 Fit Sensor inner and outer lids, switch wires & air tubes . Refer to section 3.2. Check that the air supply is connected and operational. If a 5000 Series blower is employed this must be powered. 4.3.4 Check at the Sensor that purge air is blowing from the optical aperture.
  • Page 14 SERIES 5000 Purge Air Supply, Pressure Switch and Normal LED The purge air is monitored by a pressure switch located within the inner sensor module. The operation of the switch is dependent on the differential pressure between the air input point to the Sensors outer case and the external atmosphere.
