System Requirements
Environmental
Operating temperature: 0ºC to +30ºC;
Operating temperature range over which system specifications can be met: +18ºC to
+23ºC
Relative humidity <50% noncondensing.
Ventilation
Camera: Allow at least one inch of clearance for side and rear air vents.
ST-133: There is an internal fan located at the right side of the rear panel behind an
exhaust opening. Its purpose is simply to cool the controller electronics. This fan
runs continuously whenever the controller is powered. Air enters the unit through
ventilation openings on the side panels, flows past the warm electronic
components as it rises, and is drawn out the rear of the controller by the fan. It is
important that there be an adequate airflow for proper functioning. As long as
both the controller’s intake ventilation openings and the fan exhaust opening
aren’t obstructed, the controller will remain quite cool.
Vacuum
The CCD is housed in the vacuum with the fiberoptic taper extending beyond the vacuum
chamber with a thin Beryllium window to block visible light and to admit X-rays. The
camera is shipped with a vacuum quality superior to the minimum required to assure
proper operation of the system for an extended period of time without concern for the
quality of the vacuum. See Appendix C for additional information.
Coolant
COOLANT IS HARMFUL IF SWALLOWED.
KEEP OUT OF REACH OF CHILDREN.
PI-SCX cameras with water-assisted cooling or water-only cooling require circulating
coolant (50:50 mixture of ethylene glycol and water) for proper operation. All hose
connections should be secured with good quality hose clamps.
Flow Rate: Users are advised to install a flow meter to monitor the rate.
PI-SCX:1300 > 1 liter/minute.
PI-SCX:4096 3 liters/minute (minimum).
PI-SCX:4300 3 liters/minute (minimum).
Fluid Pressure: 25 psig (maximum).
Inlet/Outlet Port Locations:
PI-SCX:1300 Two quick-disconnect coolant ports are supplied with a water-
cooled system and are mounted at the sides of the camera. For the best cooling, make
the hose connections to the Inlet and Outlet ports as shown in the outline drawing on
page 38. Use 1/4" thin-wall tubing.
