Description
A coolant level float style switch is located
in the coolant reservoir. When this interlock
is sensed, in addition to the displayed
message on the Remote Box, the reservoir
backlights will flash.
A flow-rate sensor located in the ICE450
coolant loop triggers an interlock condition
when the flow rate is less than 2.2 lpm
(+/- 10%).
A defective temperature sensor interlock
appears if any one of the three temperature
feedback signals (CG, CS or HG) is
abnormal.
The ICE450 calculates the power delivered
to the lamp. If the power per shot is more
than 450W, this interlock is activated.
Note: Under normal conditions you are
prevented from adjusting the settings too
high. The interlock prevents serious problems.
