System Shutdown, Startup, and Reset

Shutting Down the System in an Emergency

Thermo Scientific
When you are not performing analyses, you can temporarily turn off the nitrogen gas or set
the Surveyor MSQ Plus MS detector to the Off mode. Turning off the nitrogen gas between
intermittent analyses conserves the nitrogen supply. Placing the system in the Off mode
conserves the laboratory nitrogen supply and increases the life of the ion detection system.
Some of the maintenance procedures contained in the Maintenance chapter require that the
system be completely shut down. To shut down the system, you must turn the vacuum
system off.
Restarting the system after a complete shutdown requires building up the vacuum to a
working level. If you are restarting the system after moving it to a new location, we
recommend that you perform a Full System Autotune.

If you need to turn off the MS detector in an emergency, place the main power circuit breaker
switch in the Off (O) position. See
MAINS ON/OFF is located on the rear panel of the MS detector in the lower-right quadrant.
Turning the main power switch to the Off position turns off all power to the MS detector,
including the forepump. Although removing power abruptly will not harm any component
within the system, this is not the recommended shutdown procedure to follow. Refer to
"Shutting the System down for Non-Routine Maintenance"
recommended procedure.
