Applications Pump A two level multi-level used in conjunction with a dual level control relay is all you need to control your pump or valve. A third level can be used for either a high level or low-level alarm condition.

Operating Principle

Drain Mode
As long as liquid does not come in contact with level two, the relay contacts will remain in an unenergized position. If liquid rises to level two, the relay contacts will transfer to the energized position. If the liquid drops below level one, the relay will immediately de-energize.

Fill Mode
As long as the liquid remains between level one and level two, the relay contacts will remain in an unenergized state. If liquid drops below level one, the control relay will be energized. The relay contacts will remain in the energized position until the level of the liquid reaches level two. When this occurs, the relay immediately de-energizes.
