Auto shutdown
You can set up the separations module to shut down automatically after a
specified period of inactivity, which is defined as follows:
•No keyboard use
• No injections performed
• No changes sent to the separations module from a remotely connected
Empower system, MassLynx computer, or external autosampler
• An error condition that suspends the operation of the separations
module
You can leave the separations module in the shutdown state indefinitely. The
separation method you specify in the Auto Shutdown dialog box defines the
initial conditions that are applied after the specified period of inactivity. Use
the auto shutdown function:
• When there is a long delay between injections
• To minimize solvent flow after an unattended or long run
• To disable the in-line vacuum degasser
• To disable temperature controls
• To turn off detector lamps
Tip: For instrument storage lasting one week or more, use methanol or
methanol mixed with HPLC-quality water to flush the solvent delivery system
before shutdown (see “Power-off the separations module” on page 114).
To enable the auto shutdown function:
1. Press the Config screen key in the Main screen, and then press the More
screen key once.
2. Press the Auto Shutdown screen key.
3. Select a separation method to use while the separations module is shut
down.
Tip: Only the initial conditions in the method you select are used.
4. Enter a time period (in minutes) after which you want the separations
module to shut down.
Alternative: Press Clear to disable the Auto Shutdown function.
5. Press OK.
