Cool Drawer Single and Dual Sensors Operating Manual
2.4 Installing the Standard and Right Angle Sensors
Standard and Right Angle sensors may be installed in any appropriate location
within the vacuum system. Two tapped holes are provided on the back of each
single sensor body, and four tapped holes on each dual sensor body, for attaching
to the vacuum system.
2.5 Sensor Shutter Function Check
Temporarily connect an air supply to the actuator air tube and test operation for
10 to 15 cycles.
NOTE: The air supply must be 55 PSIG (70 PSIA) to 60 PSIG (75 PSIA)
(3.8 to 4.1 bar) (379 to 414 kPa)
When actuated, shutter movement should be smooth, rapid, and complete, and
should retract completely from the crystal opening. When deactivated, the shutter
should completely cover the crystal opening. Repositioning of the shutter may be
required to achieve optimum on/off positioning.
If operation is impaired, lubricate the moving parts with molybdenum disulfide or
equivalent.
NOTE: A solenoid valve (PN 750-420-G1) is required with any new shutter
installation. See Chapter 3 for more information on the solenoid valve and
its installation.
WARNING
Do not exceed 100 PSIG (115 PSIA) (6.9 bar) [689 kPa].
Connection to excessive pressure may result in personal
injury or equipment damage.
