The pump stops (U2 indicator ON) when the water level reaches
E1 and the pump starts (U2 indicator OFF) when the water level
in the tank drops below E2.
When the level of the water supply source drops below E2’, the
pump stops (U1 indicator OFF). Pump idling is prevented and the
alarm sounds.
Insert a pushbutton switch (NO contact) between E1’ and E3 as
shown by the dotted line. When starting the pump or after
recovering from a power failure, if the water supply source level
has not yet reached E1’, press the pushbutton switch to start the
pump by momentarily short-circuiting E1’ and E3. When the
pump stops during normal operation subsequent to an alarm
issued for a low water level (e.g., the water level does not reach
E2’), do not press the pushbutton switch.
