Basic Sequence of Operation 

3 pumps working independently (in manual) or through alternation (Auto mode)

  1. In Auto – Liquid rises, upper float switch closes and turns on pump 1– As liquid is pumped and level lowers– As lower float switch opens, Pump will turn off.
  2. The next time the stop and “lead” floats are closed the alternator will energize pump 2 and will continue until the stop float opens. Same sequence for the third and fourth pumps.
  3. This cycle will continue to repeat each time the liquid level rises and lowers.
  4. If liquid level continues to rise above the lead float after the first pump is energized, the lag float will close and turn on the second pump. Both pumps remain on until the stop float opens.
  5. If liquid level continues to rise above the lead float after the first pump is energized, the lag float will close and turn on the second pump. Both pumps remain on until the stop float opens.
  6. If liquid level continues to rise above the lead float after the first pump is energized, the lag float will close and turn on the second pump. If liquid level continues to rise above the lag float after the second pump is energized, the lag2 float will close and turn on the third pump. All three pumps remain on until the stop float opens.
  7. Off – Pump Off
  8. Hand – Pump on continuously until switch is turned off
