72 I-PentaMAX System Manual Version 3.A
Alarm Sounds Sporadically
It is normal for the alarm to sound briefly when the high-voltage supply is first turned on.
However, if the alarm sounds sporadically, contact the factory at once. This may indicate
intensifier damage or another situation that requires immediate attention.
Alarm Sounds Continuously
Immediately reduce the light entering the camera. This can be done by decreasing the
lens aperture, completely blocking the light into the camera window with a lens cap or
equivalent, or by switching
MCP POWER/OFF to "OFF" until you lower the source
illumination.
If the alarm sounds continuously even when the illumination level is adequately low,
switch the
MCP POWER/OFF to "OFF" and switch the IIC-200 (IIC-300, IIC-100, or
MCP-100)
POWER to "OFF". Then contact the factory: this may indicate intensifier
damage or another situation that requires immediate attention.
Baseline Signal Suddenly Changes
There are two possible reasons for this change:
• The temperature setting has been changed. In this case, a change in baseline
signal is normal.
• There may be excessive humidity in the intensifier enclosure of the camera. If
the temperature setting has not been changed and you observe a baseline signal
change, turn off the system immediately. An excess humidity condition should
be corrected promptly or permanent damage not covered by the Warranty could
occur. Have the unit serviced by Princeton Instruments or an authorized service
facility of Princeton Instruments.
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:
• Turn off all AC power.
• Verify that all cables are securely fastened and that all locking screws are in
place.
• Check for a burned-out fuse in the Temperature/ Power Supply power module.
For information about changing a fuse, see "Fuses are not Correct for the Line
Voltage" on page 77.
• Correct any apparent problems and turn the system on.
• If the system still does not respond, contact Technical Support.
