Pump Control

The pump can be switched between following states: On, Off or to Standby. In
Standby, the pump motor is still controlled. When the pump is switched on
from standby, it does not re-initialize.
Upon initialization, the pump ignores the Maximum Flow Gradient value.
C AU T I O N
This can result in a rapid and uncontrolled pressure increase.
➔
The optional seal wash pump can be controlled by either switching it off, using
it for a single time or specifying frequency and duration of periodic wash
intervals.

Description
Free text field for a description of the solvent. This description will show up in
method printouts, etc.
Use the timetable to build solvent gradients, flow gradients, or combinations of
both. Gradients are always linear. Use multiple timetable entries to mimic
exponential or parabolic gradients.
There are three ways to display the timetable:
• in tabular form
• as flow/pressure graph
• as solvent percentage plot
Values can only be changed in tabular view.
To prevent harm to the column, open the purge valve until the initialization is
finished.
