Water Source Level Indication, Prevention of Pump Idling Due to Water Shortage, Automatic Water Supply Control, and Indica-
tion of Water Level in Tank

Note: 1. Be sure to ground terminal E8.
Insert four Electrodes in the water supply source and five
Electrodes in the elevated water tank.
The lower-limit indicator for the water supply source remains ON
while the water source level is below E3 (U2 indicator OFF).
When the water level rises to E2, the lower-limit indicator turns
OFF (U2 indicator ON) and the pump is ready for operation.
When the water level reaches E1, the upper-limit indicator turns
ON (U3 indicator ON).
The water-shortage indicator for the elevated tank remains ON
while the water level in the elevated tank is below E7. The
indicator turns OFF (U1 indicator ON) when the water level rises
to E7.

The pump stops (U5 indicator ON) when the water level reaches
E5 and starts (U5 indicator OFF) when the water level drops
below E6.
If the water level reaches E4 for any reason, the tank repletion
indicator for the elevated tank turns ON (U4 indicator ON).
Insert a pushbutton switch (NO contact) between E2 and E8 as
shown by the dotted line. When starting the pump and after
recovering from a power failure, if the water source level has not
yet reached E2 (U2 indicator OFF), press the pushbutton switch
to start the pump by momentarily short-circuiting E2 and E8.
When the pump stops during normal operation subsequent to an
alarm issued for low water level (i.e., the water level has not
reached E3), do not press the pushbutton switch.
