Water Cooling
Supplemental water cooling can be implemented via the camera’s back panel two
cooling ports, either of which can be used for inflow or outflow. Connect to the ports
using ¼
cooling ports, either of which can be used for inflow or outflow. Connect to the ports
using ¼
″ inner diameter Tygon tubing secured with a suitable clamp (barb-sleeve clamps
(2518-0301) are provided). Although pressures as high as 80 psi can be applied,
satisfactory cooling will ordinarily be attained with a lower pressure and moderate flow
rate. Supplemental cooling will allow temperature lock to be achieved more rapidly than
would be required to attain lock at the same temperature with air cooling alone. In
addition, it will be possible to achieve temperature lock at lower temperatures, typically
three or four degrees lower than would be possible with air cooling alone.

It is essential that the cooling water not be chilled. The circulation of chilled water can
cause condensation inside the camera that could cause the electronics to malfunction.
Ordinary tap water can be too cold and should not be used! The water should be no
colder than the laboratory ambient temperature. Closed circulation systems (such as the
CC-100) that depend on ambient air cooling of the circulating water will generally give
good results.

Error Conditions
The red ERROR indicator on the front panel of the Temperature/Power Supply will
light when a temperature-control error condition is detected. At the same time, the
temperature control loop will shut down independent of the setting of the Temperature
Control On/Off switch. When this happens, the temperature will begin rising towards
ambient, even though the yellow STATUS indicator remains lighted and even if the
error condition is corrected. It is always necessary to cycle the power before normal
temperature control operation can be re-established. Ordinarily you would turn off the
power, identify and correct the error condition, and then turn the power back on and
operate as usual. Refer to Chapter 10, Troubleshooting, for possible causes and
corrective actions.

Note: The inside of the camera must reach a certain temperature before control can be
re-established. You may have to wait for this to occur before regaining temperature
control.

Pressurization
Before an I-PentaMAX leaves the factory, its front enclosure is evacuated and then
backfilled with clean dry air at a pressure of nominally 1 psi. For proper operation it is
essential that the integrity of the front enclosure be maintained. Do not remove the
window from in front of the intensifier or loosen the pressure valve. If this enclosure
should be opened to the air, the array and intensifier will be exposed to atmospheric
moisture, which could condense on the array as it cools and possibly cause irreversible
damage. If accidentally opened to the atmosphere, do not operate the camera. Contact
Princeton Instruments Customer Support for further instructions.

Operating an I-PentaMAX that is no longer backfilled with dry air or dry nitrogen may
result in condensation on the array that could cause irreversible damage. Such damage
would not be covered by the Warranty.
