Camera Stops Working

Problems with the host computer system or software may have side effects that appear to
be hardware problems. If you are sure the problem is in the camera system hardware,
begin with these simple checks:
1. Turn off all AC power.
2. Verify that all cables are securely fastened and that all locking screws are in place
and all slide latches are in the latched position.
3. Correct any apparent problems and turn the system on.
4. If the system still does not respond, contact Customer Support.

Cooling Troubleshooting

Temperature Lock Cannot be Achieved or Maintained.

Possible causes for not being able to achieve or maintain lock could include:

Ambient temperature greater than +20°C. This condition affects TE-cooled cameras.
If ambient is greater than +20°C, you will need to cool the camera environment or
raise the set temperature.

Airflow through the camera and/or circulator is obstructed. The camera needs to have
approximately two (2) inches (50 mm) clearance around the vented covers. If there is
an enclosure involved, the enclosure needs to have unrestricted flow to an open
environment. The camera vents its heat out the side vents near the nose. The air
intake is at the rear of the camera.

A hose is kinked. Unkink the hose.

Coolant level is low. Add 50:50 mix of ethylene glycol and water. Refer to
manufacturer's instructions for adding coolant.

There may be air in the hoses. Remove air and add 50:50 mix of ethylene glycol and
water. Refer to manufacturer's instructions for removing excess air and adding coolant.

Circulator pump is not working. If you do not hear the pump running when the
circulator is powered on, turn off the circulator and contact the manufacturer's
Customer Support.

CoolCUBE
that it is 6 inches (150 mm) or more below the camera. The vertical distance should
not exceed 10 feet (3 m). Typically, the camera is at table height and the circulator is
on the floor.

The target array temperature is not appropriate for your particular camera and CCD array.

The camera's internal temperature may be too high, such as might occur if the
operating environment is particularly warm, if you are attempting to operate at a
temperature colder than the specified limit, or if you have turned off the fan and are
not circulating coolant through the camera. TE cameras are equipped with a thermal-
protection switch that shuts the cooler circuits down if the internal temperature
exceeds a preset limit. Typically, camera operation is restored automatically in about
