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:
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 unacceptable 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.
