Parameter Limits
Stoptime 0.01 – 99999 min or As
Injector/No Limit (an
infinite run time).
Posttime 0.01 – 99999 min or
Off (0.0 min ).
Pressure Limits Max: 1200 bar
(17400 psi) for flow
rates up to 2 mL/min.
For flow rates
between 2 mL/min
and 5 mL/min, the
maximum pressure
ramps down to
800 bar (11600 psi).
Min: any value
between 0 and the
upper pressure limit

Setting up the Pump with the Instrument Control Interface
Description
The stoptime sets a time limit for your analysis. After the stoptime, all
gradients are stopped and the pump parameters return to their initial
values. The pump can be used as a stoptime master for the complete
analytical system. The pump also stops the detectors if they have a No
Limit stoptime setting. If no limit is given, a method will have to be stopped
manually.
Your instrument remains in a not ready state during the posttime to delay
the start of the next analysis. You can use the Posttime to allow your
column to equilibrate after changes in solvent composition (for example
after gradient elution).
Sets the maximum and minimum pressure limits for the pump.
• Max is the maximum pressure limit at which the pump will switch itself
off, protecting the analytical system against over-pressure.
• Min is the minimum limit at which the pump will switch itself off, for
example, if any solvent reservoir is empty, this prevents system damage
by pumping air.
