PRESSURIZED INTEGRATED OPTICS CARTRIDGE
The pressurized IOC houses an auto focus camera, lens, heater, and sensors in a self-contained, sealed unit. Dry nitrogen pressurized to 10
psig controls the environment inside the cartridge, eliminating internal condensation and corrosion.
Sensors strategically placed inside the pressurized IOC continually monitor pressure, temperature, and relative humidity. If internal
conditions reach unacceptable levels, an alert label appears on the screen describing the alert condition. Example: If pressure drops below
1 psig, LOW PRESSURE is displayed on the monitor.
The following conditions will trigger an alert:
CONDITION ALERT LABEL
1 psig Low Pressure
25 psig High Pressure
-40°CLow Temperature
60°CHigh Temperature
20% High Relative Humidity
ALERT LABEL CYCLE
The Esprit system continually checks internal environmental conditions every 60 seconds. An ALERT label appears on the monitor if
conditions are beyond manufacturer set acceptable limits. The label will be repeatedly displayed until acknowledged by the system
controller. Once acknowledged, alert behavior changes to the programmed acknowledge action. If the alert condition remains unaccept-
able after a period of time, the ALERT label will reappear on the monitor, restarting the alert label cycle. The cycle will continue until the
alert condition is resolved.
ALERT RESET
The Alert Reset function clears alert conditions and removes the ALERT label. The system will automatically check internal environmental
conditions 60 seconds after reset. If conditions remain beyond manufacturer set acceptable limits, the ALERT label will reappear on the
screen indicating further corrective action is required.
