Automatic Water Supply and Drainage Control with Abnormal Water Shortage Alarm and Water Tank Repletion
1. Water Supply

•
Note: 1. The diagram shows the connections for the water supply. When draining, change the connection from terminal Tb to terminal Ta.
Connect electromagnetic switch coil terminal A with Tb.
The pump stops (U2 indicator ON) when the water level reaches
E2 and starts (U2 indicator OFF) when the water level drops
below E3.
If the water level rises to E1 for any reason, the upper-limit
indicator turns ON and the alarm sounds (U1 indicator ON).
If the water level drops below E4 for any reason, the lower-limit
indicator turns ON and the alarm sounds (U3 indicator OFF).
2. Be sure to ground terminal E5.
