10.2.1 Setup
The application wizard guides you through the various configuration
possibilities and options. The following steps are performed:
Select application
Select the application " Pumping station
" from the options offered.
Assign measuring loop name
Assign a unique designation to the measuring point so that there can
be no confusion with other measuring points.
Define sensor characteristic values
The measuring range suitable for the application should be set di-
rectly in the sensor to achieve the maximum accuracy. This measuring
range must now be stored once again in the assistant together with
the sensor type and measuring unit.
Define adjustment values
Enter the adjustment values of the measuring point for 0 % and for
100 %.
Define mode of operation of the pump control
Define the desired operating mode of the pump control: pump control
1/2 (same running time) or pump control 3/4 (fixed sequence). In
addition, you can select the mode sequenced or alternating pump
operation. The setup wizard and the following application examples
provide you with details on how it works.
Configure pumps
In this step a forced pump changeover can be activated. Details on
the mode of operation are provided by the setup wizard and the fol-
lowing application examples.
Configure relay switching points
Enter the relay switching points at which the pumps should be
switched.
Configure measured value indication
In the last step you can configure which and how many measured
values are to be shown on the display. In addition, you can define
the base of the display value, the display format and the optional bar
graph.
10.2.2 Application example pump control 1/2
Pump control 1/2 is used to control several pumps with the same
function, in dependence on their respective elapsed running times.
The pump with the shortest elapsed running time is switched on
and the pump with the longest running time switched off. In case of
increased pumping requirement, all pumps can also run at the same
time, in dependence on the entered switching points. This measure
achieves an even utilization of the pumps and increases operational
reliability.
