Description
Power-save sets the instrument into power saving mode. When
the function is enabled, the instrument enters power-saving mode
after having been in state Ready for a certain time period. The
instrument turns into state Ready when a method run, a method
queue or a manual run ends. The time interval before the instru-
ment enters power-saving mode is defined by the user.
Instrument control panel locks/unlocks the control panel located
on the front side of the instrument. When unlocked, the buttons
on the Instrument control panel are active and can be used to
control a few basic functions of the instrument. When the Instru-
ment control panel is locked, no functions are available.
By using Pressure control the method can be run with the set
flow rate without the risk of method stop due to pressure alarm.
Pressure control is enabled in the instruction System flow or
Sample flow. Pressure control parameters provides the P and I
factors used in the regulator and can be adjusted for different
columns.
Constant pressure flow parameters sets the values for the P and
I factors needed to keep a constant pressure by varying the flow
rate. The signal used for pressure control is set in the instruction
Constant pressure flow.
Max flow during valve turn sets the maximum flow rate used
during the turning of the injection and outlet valve in order to
avoid high pressure alarms.
Method progressing flow sets which flow (automatic, system
flow, sample flow) the progress of the method is calculated after.
In automatic mode, the position of the injection valve determines
if the system flow or the sample flow is used.
Sample pump setting enables sample pump flow while the injec-
tion valve is in manual load position.
