2.2 Analyser shutdown
Attach a dry air supply to the calibration port of the sensor head
and purge the sensor head for 5 minutes at 600 ml/min flow
rate. The aspirator air supply should be left on at this point.
Switch off the aspirator air supply to the sensor head.
Switch off the electrical supply at the control unit and then at the
sensor head.
Leave the sensor head to cool down for a minimum of two
hours.
If the analyser is to be un-powered for more than 1 week then
please note the cautions above.
WARNING
The sensor head is heated and may be attached to a hot
flue. The external surfaces will be uncomfortably hot even
after power down for several hours. Exercise care when
handling the sensor head even when un-powered on a hot
flue.
CAUTION
• The sensor head should always be powered when left on
a flue which is in use. If left un-powered, the sensor head
can suffer corrosion damage.
• If the process is out of service for a short time it is
recommended that the analyser sensor head is left
powered. It is not essential that the aspirator air is left
flowing.
• If the analyser has to be switched off for more than
1 week whilst on a flue which is in use, it is
recommended that a flow of dry air be connected to the
calibration port. Alternatively, the sensor head can be
removed from the flue and a blanking plate fitted. This will
prevent corrosive gases from entering the sensor head.
