Figure 19. Manual-Off-On SW. (AUTO Position)
4.In the AUTO mode the pump will run as long as there is a sufficient amount of water for the start float switch to be activated. This water level is determined by the setting of the float switches.
The stop float switch contacts will open when the water level is low and power will be removed from the pump's motor.
5.Once the water level has risen back to the appropriate level the start float switch contacts will close and power will be restored to the pump's motor.
