3. Pumping sequence example #3: Pump #2 is set for “Lead”, pump
#1 is set for “Lag 1” and pump #3 is set for “Lag2”. When the level
requires a pump to run, pump #2 comes on and runs until the level is
satisfied. If the level continues to change and requires another pump
to run, pump #1 will start. If the level still continues to change and
requires another pump, pump #3 will start. The pumps will continue
to run until the stop level is satisfied. With all pumps now off, when
the level requires a pump to come on, the sequence repeats itself,
there is no alternation.
