6.4 Power On/Off Control
The power switch on the device is the main switch for power on/off
control. The main power switch is turned on during initial installation of
the device.
For easier handling, you can use the power button on the front left of
the Vanquish system base (system power button) for power on/off.
Observe the following:
• All modules in the Vanquish system that are connected to the
system base via system interlink cables are turned on or off
simultaneously when the system power button is pressed.
• When the power is on, the system power button is pressed in. When
the power is off, the system power button stands out.
• If the main power switch on a device is off, you cannot turn on the
device with the system power button.
• To turn off a device completely, you have to turn it off with the main
power switch on the device. Pressing the system power button will
not be sufficient to turn off the power to the device completely.
The following sequence of events occurs when the device is powered up
and the front doors are closed:
• The device runs a series of internal tests. (The test takes about
30 seconds.) During these self-diagnostics, all of the main
components are checked.
• After the self-test, the device starts basic initialization. During this
time, the LED bar is flashing green.
• The LED bar turns green if initialization was successful.
If the LED bar turns red, verify that a flow cell is properly installed,
and press the
INIT button on the keypad to re-initialize. The LED bar,
and the LED next to the INIT button both turn green if initialization
was successful.
