DIP Switch Pin 1: OFF (Automatic Liquid Supply
Operation)
• When the liquid level falls to E2 (indicator turns ON), the pump
starts.
When the liquid level rises above E1 (indicator turns OFF), the
pump stops.
DIP Switch Pin 1: ON (Automatic Liquid
Discharge Operation)
• When the liquid level reaches E1 (indicator turns ON), the pump
starts. When the liquid level falls below E2 (indicator turns OFF),
the pump stops.
