Configuring Events / Digital Outputs
This option is given only for the S 1050, P2.1L, S 1000, K-1001, and K-
1800 pumps. The spreadsheets of the S 100 / 10P/20P/P2.1S/P4.1S, K-
120, K-501, and the Kontron pumps do not include this column. Configure
the events by pressing the button which is displayed when you place
the cursor on the Events cell. The following dialog will appear.
Fig. 131 Configuring Digital Outputs
The Events (Digital Outputs) correspond to the outputs available on the
rear panel of the pump.
Select the state for each Event you want to set from the drop-down list.
The choices are Off (0), On (1), and Pulse (P). Refer to the pump’s user
manual for details about digital outputs parameters.
Use the All On or All Off buttons to switch all of the outputs either on or
off.
Constant pressure mode (Isobar) (P2.1L only)
If in the instrument configuration the gradient mode for the pump P2.1L is
set to Isobar, the setup windows looks different:
Fig. 132 Instrument setup window P2.1L constant pressure mode (isobar)
Constant Pressure Mode: Flow Limits (ml/min): Set the allowed flow
range for this operating mode. The allowed absolute minimum is 0
ml/min, the maximum depend on the selected pump head.
Pump program – Pressure (unit): Enter the desired system pressure.
The pump will vary the flow, if the pressure in the system will change.
The pressure unit depends on the unit selected in the pump’s instrument
configuration. The minimum time step between two time lines is 0.25 min.
