control software.
Bottle Filling
The pump offers a powerful feature to monitor the liquid level in the solvent
bottles. With total bottle volume and initial filling volume set correctly, the
pump subtracts the consumed volume continuously from the initial value and
stops the pump and method/sequence execution before the system runs dry or
an analysis is corrupted.
Table 5 on page 44 lists the available bottle filling parameters.
N O T E
The pressure data curve is generated from the pressure sensor readings, while %A, %B
and flow are calculated from the method settings of the pump.
C A U T I O N
The bottle filling feature fails if multiple solvent inlets are put into one solvent bottle!
➔
In that case implement a minimum pressure limit to avoid that the pump runs dry
when solvents are empty.
Table 5 Bottle Filling Parameters
Parameter Limits Description
• Total
Volume 0 – 1000 L
default: 0 L This is the capacity (maximum possible volume) in liter of the solvent bottle. In
combination with the actual volume, this parameter is used for calculating and
displaying the relative liquid level.
• Actual
Volume 0 – 1000 L
default: 0 L After filling the solvent bottles, enter the actual volumes into these boxes. The
Actual Volume must not be larger than the Total Volume of the bottle.
