High Intensity Light Damage
Intensified CCD cameras such as the PI-MAX, when biased ON, can be irreparably
damaged if continuously exposed to light levels higher than twice the A/D saturation
level. Thus it is critical that you not establish conditions that could result in damage to
the intensifier. Although intensified cameras are less prone to damage from background
light when operated gated, they are at significant risk to damage from high-intensity light
sources like a laser. High intensity sources can damage the intensifier before the
protection circuits have time to respond, or even cause spot damage without the
protection circuits acting at all. In Shutter Mode operation, it will be necessary to keep
the lab lighting be subdued when working with an intensified camera. If a sustained
alarm indication occurs when the controller is turned on, immediately switch the MCP
On/Off switch on the back of the PI-MAX to the OFF position. Cover the detector
window and only switch the MCP On/Off switch to ON after the illumination level has
been lowered.
If the alarm sounds continuously even when the illumination level is adequately low, shut
the system down and contact the factory for guidance.
Precautions
To prevent permanently damaging the system, please observe the following precautions:
Always switch off and unplug the ST-133 Controller before changing your system
configuration in any way.
Whenever you turn the ST-133 power OFF, be sure to leave it OFF for at least 30
seconds before switching it back ON. If you switch it ON too soon, a fault logic state
is established that causes the overload alarm to sound continuously.
Never remove the camera’s front window, as it is necessary to maintain vacuum (or
to maintain a dry nitrogen environment).
The CCD array is very sensitive to static electricity. Touching the CCD can destroy
it. Operations requiring contact with the device can only be performed at the factory.
Never operate the camera cooled without proper evacuation or backfill. This could
damage the CCD!
Never connect or disconnect any cable while the PI-MAX system is powered on.
Reconnecting a charged cable may damage the CCD.
Never prevent the free flow of air through the equipment by blocking the air vents.
Cleaning and Maintenance
Cleaning the Controller and Camera
Although there is no periodic maintenance that must be performed on the PI-MAX
Camera, users are advised to wipe it down with a clean damp cloth from time to time.
Note: The cloth should be just damp enough to pick up dust – not wet.
This operation should only be done on the external surfaces and with all covers secured.
In dampening the cloth, use clean water only. No soap, solvents or abrasives should be
