When operating with one pump:
- the pump relay uses for pump control;
- the functional relay uses for alarm activation.
The alarm is activated (contacts "5
– 6" are closed) in the following cases:
– liquid level is higher than
EL
;
– liquid level is lower than
DR
;
– failure of
UL
,
LL
or
DR
sensors.
