The Standby State - Agilent Technologies InfinityLab LC Series User Manual

The OFF state is always entered after a successful power-up sequence. It can
also be entered by selecting the Off option in the control window, by a timeout
from the STANDBY state or by pressing Off in the Agilent ChemStation
graphical user interface twice in succession.
When the Agilent 1260 Infinity II Control Module is in the OFF state, the top
"power" status light is constant and the bottom "ready" status light is off.

The booster pump drive is unpowered.

The STANDBY state can also be entered by selecting the Standby option in the
control window, by pressing the power button associated with the SFC icon of
the GUI, or by pressing Off in the ChemStation graphical user interface once

When the STANDBY state is entered from the OFF state, the BPR must be
homed. Once this is accomplished, the BPR drive is active but in a hold state.

the two status lights flash alternately. The STANDBY state remains active for up
to three hours. If no user-initiated action is taken to change or renew the state
within this time, a timeout occurs and the processor automatically enters the
