the Off (O) position, the following occurs:
• All power to the mass spectrometer is turned off. (All LEDs on the front panel of the mass
spectrometer are off.)
• A capacitor on the Vent Delay PCB provides power to the vent valve for two to four
minutes (to allow the turbomolecular pump to spin down). After the capacitor discharges,
power to the vent valve solenoid shuts off. When power to the vent valve solenoid shuts
off, the vent valve opens and the vacuum manifold is vented to filtered air.
• After about two minutes, the pressure of the vacuum manifold reaches atmospheric
pressure.
CAUTION Allow heated components to cool before servicing them.
