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 switching MCP
ON/OFF switch on the back of the PI-MAX to "OFF" until you lower the source
illumination, by decreasing the lens aperture, or by completely blocking the light into the
camera window with a lens cap or equivalent until the light level has be lowered.
If the alarm sounds continuously even when the illumination level is adequately low,
switch the MCP ON/OFF to "OFF" and turn the ST-133 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
and all slide latches are in the latched position. For instructions on operating the
slide latch locking mechanism, see "Securing the Detector-Controller Cable Slide
Latch", page 181.
Check for a burned-out fuse in the Controller power module. For information about
changing a fuse, see "Changing the ST-133 Line Voltage and Fuses" on page 168.
Correct any apparent problems and turn the system on.
If the system still does not respond, contact Customer Support.
