iCAP Customer Familiarisation Manual
Torch Compartment Interlock:- If red this indicates the torch door is open or the torch holder is
not inserted correctly. The plasma will not light.
Plasma gas pressure:- should be green if the plasma gas input pressure is 5.5 Bar, if it turns red
during the ignition sequence it indicates problems with the external gas supply to the iCAP If red
the plasma will not light.
Purge gas pressure:- should be green if the input pressure for the plasma gas is 5.5 Bar, if it
turns red during the ignition sequence it indicates problems with the external gas supply to the
iCAP. If red the plasma will not light.
Detector water flow:- should be green if the correct water flow is flowing for the camera to cool
down and the RF to light the plasma. If red the plasma will not light. (If the LED flickers even
slightly the plasma will go out and this indicates there is a problem with the chiller.
Drain Flow sensor:- if this is red this indicates that the iCAP has not seen an air bubble in the
drain sensor for two minutes, it will turn the plasma off. To reset the drain sensor turn the pump
on to 45RPM.
Exhaust flow;- This interlock checks that the exhaust is of sufficient flow to ensure the safe
removal of heat and combustion gases. (In a 20 second period the extraction needs to be low for
5 seconds for the interlock to occur.
Detector Temperature:- This interlock indicates that the camera has cooled down to -45ºC and
is ready to measure samples. (Notes: RED = too hot, Green = -45ºC Blue = Too cold.) When the
chiller is turned on the camera will take 5 minutes to cool down to -45ºC.
Optics temperature:- This indicates that the optical tank has reached the operating temperature.
From cold it could take 2 hours to reach 38ºC and an additional 1 hour to fully stabilize.
