Shutting Down the System in an Emergency
Shutting Down the System in an Emergency
If you need to turn off the MS detector in an emergency, place the main
power switch (located on the power panel at the right side of the
LTQ Orbitrap XL) in the Off (O) position. This turns off all power to
the instrument, including the linear ion trap, multiple socket outlets for
the data system, and the vacuum pumps. The main power switch must
be turned 90° anti-clockwise to switch off the instrument. See
Figure 2-1.

On
The instrument is automatically vented by the vent valve of the linear
ion trap. The vent valve vents the system 30 s after power is switched
off.
Although removing power abruptly will not harm any component
within the system, this is not the recommended shutdown procedure to
follow. Refer to topic “Shutting Down the System” on page 2-5 for the
recommended procedure.
Note To separately turn off the recirculating chiller or computer in an
emergency, use the On/Off switches on the chiller and computer,
respectively. ▲
A main power failure has the same consequence as switching off via the
main power switch. If the power is available again, the system is started
up automatically i.e. the pumps are switched on and the vacuum is
created. If the system has been vented during the mains failure, it is
necessary to bake out the system to obtain the operating vacuum. Refer
to the topic “Baking Out the System” on page 3-4.
