Operating Logic: Assuming an empty tank, upon application of voltage to the system, the filling output is turned on and the heater output is off. As the liquid fills the tank, and when it reaches the low probe (above the heater), the heater output is turned on. The level will rise until it reaches the high probe causing the filling output to turn off. As the liquid is removed from the tank, 2 to 4 seconds after it breaks contact with the high probe, the filling output is turned on and stays on until the liquid reaches the high probe. This time delay eliminates fill output chatter if the liquid is splashing. If the tank is non-conductive, a third (common) probe must be installed at a level where it will always be submerged.
