Powering Up The Switchos - LC Packings SWITCHOS II User Manual

The User Interface

When the Switchos Advanced Microcolumn Switching Unit is powered up via the
main power switch on the rear panel (FIGURE 2-1), it will go through an
initialization/self-test protocol. During this period, all LEDs on the front panel will
be illuminated for a short period of time and a number of messages are displayed
on loading pump indicating that various components are functioning properly.
After completion of this procedure, the Main Screen appears on the display of
the loading pump (FIGURE 3-1) and the Solvent Selection Valve will be switched
to channel A. The LEDs indicating the current status of the Switchos (e.g. LED 1-
2 in the upper front panel indicates that valve A is in position '1-2').
Note: The initialization procedure takes a few seconds. The instrument is ready
to use when LED A of the SSV LEDs is illuminated.

The system can be switched into standby mode (e.g. when not used over night)
by pressing the ON/STANDBY push button (FIGURE 3-2) for greater than 2
seconds. This turns off the power to the loading pump, illuminates the Standby
LED and places the Switchos into standby mode. When the system is in standby
mode, pressing the button for a short time will power on the system again (and
switch the Standby LED off).
