NEMA 4X - OUTDOOR

THREE FLOAT OPERATION
The pump control panel shall be equipped with three float switches to control, by volume, each dose to be discharged. The dosing volume is adjustable by increasing or decreasing the distance between the "Pumps Off" (Bottom) and "Pump On" (Second) float. When the water level rises high enough to overcome the "Pump On" float, the lead pump will activate and continue to run until the water level drops below the "Pumps Off" float. The control will then alternate the lead pump. If the water level continues to rise and reaches the "Lag Pump" (Third) float, the lag pump will activate the alarm and both pumps will continue to run until the water level drops below the "Pumps Off" float. The audio/visual alarm will be latched in until the alarm silence switch is pressed, at which time the audio alarm will be silenced. The visual alarm will remain lit until the liquid level drops below the "High Level/Lag" float.

FOUR FLOAT OPERATION
The alarm should be placed in the third position and the lag pump in the fourth position. If the water level continues to rise and reaches the "High Level" (Third) float, the audio/visual alarm will activate and be latched in until manually acknowledged. If the water level continues to rise and reaches the "LAG" (fourth) float, the lag pump shall activate and continue to run until the water level drops below the "Pump Off" float.
