Two-wire Automatic Water Supply and Drainage Control
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 to Tb.
The pump stops (indicator ON) when the water level reaches E1
and starts (indicator OFF) when the water level drops below E2.
2. Be sure to ground terminal E3.
