System Overview
To turn on the system
Certain conditions outside the direct control of the instrument firmware must be
satisfied before the turbo pumps will be initiated. The Curtain Gas™ supply must
be turned on at the source, and the roughing pump must be turned on manually.
Interlocks (pressure switches) monitored by the firmware detect if the Curtain Gas
supply and the roughing pump are switched on. If the interlocks are not satisfied,
the turbo pumps are not initiated.
CAUTION! If the ion source is removed, the system electronics will be disabled,
interrupting any data acquisition tasks. The turbo pump and the vacuum system will not
be affected.

CAUTION! If the vacuum chamber is not going to be vented while the
instrument is shut down, we recommend the roughing pump remain turned on
to prevent the pump exhaust from being sucked back into the vacuum chamber.
If you do not want to vent the vacuum chamber, skip steps 6 and 7.
5. Turn off the main power to the instrument. As you face the instrument
where the instrument name is visible and with the source to your left, the
switch is located on the bulkhead at the back right corner of the chassis.
6. After fifteen minutes, turn off the roughing pump. The power switch is
located beside the power supply input attachment on the roughing
pump.
Note: The roughing pump has its own power toggle switch and must be turned
off manually. The roughing pump is not controlled remotely by the system
controller.
7. Let the vacuum chamber vent naturally through the orifice for ten minutes
to allow the instrument to reach atmospheric pressure.
8. Unplug the mains power cord to the instrument from the rear bulkhead
near the main power switch for the instrument.
1. Turn on the roughing pump, if it was turned off. The power switch is
located beside the power supply input attachment on the roughing
pump.
Note: The roughing pump has its own power toggle switch and must be turned
on manually. The roughing pump is not controlled remotely by the system
controller.
2. Make sure that all gas supplies are flowing correctly to the instrument.
3. Plug the mains power cord into the bulkhead.
4. Turn on the main power switch.
5. Make sure that the GPIB (general purpose interface bus) cable is
connected to both the instrument and the computer.
