The sensor lamp housing is cooled by clean air supplied at a rate of 2 to 3 CFM by one of two alternate air sources provided with the system.
One air source is a filter/regulator assembly that makes use of plant compressed air. Plant air is heavily filtered by a set of filters, and the air flow to the sensor is controlled at 2 to 3 CFM. This assembly includes a flow sensor that turns off the power to the sensor if the flow rate is too low.
The filters in this assembly use replaceable filter elements which should be changed if they become blocked or contaminated. This assembly should be inspected regularly (once per week initially).
The filters must be checked regularly (once per week initially) and cleaned or replaced if necessary to ensure that they do not become blocked with airborne contaminants. If the air flow from this assembly to the sensor is too low due to blocked filters, an indicator light on the box is turned on. If this condition is not corrected promptly, damage to the sensor may result.
