12.3.3 Pump setpoints with two independent wells
The Setup Wizard allows the user to create a pump control configuration with more than one well. If
"independent wells" is selected, (i.e. no hydraulic connection between the wells), this section explains how
to change pump setpoints.
The standard pump setpoints screen is still used but certain rules are in place for normal operation which
makes the setup for independent wells a little more difficult.
The following example is a 4-pump station with 2 pumps in well 1 and 2 pumps in well 2.
• P1 and P2 are automatically assigned to well 1.
• The required start/stop points are 50/10 for lead (duty) and 60/20 for lag (standby) for both wells.
• The pump setpoint screen will be similar to Figure 89 - Setting Pump Levels (except with 4 pumps).
Change the setpoints to 50/10, 50/10, 60/20, 60/20.
• Now go to the Alternation and Grouping screen (see Section 13.2), and while keeping the pumps in
alternation mode, change the order of the pumps to P1, P3, P2, P4.
If the station operation is now tested, P1 and P2 are in well 1 and the start points are 50% for the lead pump,
and 60% for the lag pump. Well 2 contains P3 and P4 and have identical start/stop points.
To enable or disable the Independent Wells options, navigate to:
