Creating an Instrument Control Method 85
Instrument Setup – Pumps
The pump setup window shows several areas. Their appearance may
depend as well on the selected pump as on the settings while configuring
it.
Working Mode
Fig. 121 Working mode in pump setup window
Using the Kontron pump 325 additionally a CAM correction can be set.
The correction value can be selected from 1 through 5.

In case of isocratic or high pressure gradient no setting can be made. In
LPG mode (except the Kontron x25 pumps) you can define the cycle time
of the valves via the drop down list.
Control Pressure Limits
Fig. 123 Pressure limits in pump setup window
This section allows you to enter the control pressure limits in the units
which have been chosen in the pump configuration dialog. The pump will
automatically shut down its operation when the measured pressure is out
of the limits. This option is not accessible in the case of the pump K-120,
10P, P2.1S or S 100 without pressure transducer.
Min Pressure
Enter the minimum pressure allowable for your pump. The zero
setting disables the shut down due to minimum pressure.
Max Pressure
Enter the maximum pressure allowable for your pump. The default
value always corresponds to the configured pump head. A setting
above this value is not allowed.
If for the min and max limit “0” is set, the software will not check for the
pressure and the limits will only be monitored by the pump internally.
