Hoffman Media EDD-4C manual Automatic Control, Setting Normal pump on Mode Drip Rates

Page 16

Automatic Control

When the Control Mode toggle switch SW17 is in the lower AUTO position (item 8 in Figure 6), the Dripmaster automatically stabilizes the preset drip rate. At the end of each 60 second interval, a short correction command is given only if there is a deviation from the desired preset drip rate.

The valve closes if the actual drip rate is 2 drips/minute or more than the preset value.

The valve opens if the actual drip rate is 1 drip/minute less than the preset value.

Setting Normal (pump on) Mode Drip Rates

During normal operation (when the well pump is operating), the drip rate is selectable for drip rates of 20, 25, 30, 35, or 40 drips/minute (Figure 6).

The toggle switch positions for each drip rate are shown below.
