The circulator is higher than the camera. Reposition the circulator so 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 the specific camera and CCD
array.
• The camera's internal temperature may be too high.
This may 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 ten minutes. Although the thermo-protection switch
will protect the camera, you are nevertheless advised to power down and correct the
operating conditions that caused the thermal-overload to occur.
17.8 Data Loss or Serial Violation
You may experience either or both of these conditions if the host computer has been set up
with Power Saving features enabled. This is particularly true for power saving with regard
to the hard drive. Make sure that Power Saving features are disabled while you are running
WinView/32 or WinSpec/32.
17.9 Error Occurs at Computer Power Up
If an error occurs at boot up, either the Interface is not installed properly or there is an
address or interrupt conflict. Turn off the computer, try a new address or interrupt and
reinstall the card. Be sure the Interface is firmly mounted in the slot.
CAUTION!
!
Since interrupts and DMA channels cannot be shared, make
sure no other boards in your computer use this interrupt or
these DMA channels.
