4000/2 automatic (Art. 1742):
Automatic mode:
The pump automatically switches off as soon as no more water is
retrieved. Due to the non-return valve, the pressure is maintained in the
hose until water is drawn via the hose. When water is drawn via the
hose (the pressure in the hose falls below approx. 1.3 bar), the pump
switches on automatically.
Dry-Running Safety:
When there is no liquid to pump, the pump automatically switches off.
The pump then switches in the cycle on 30 sec. – 5 sec. off (4 x). In 1 hr.,
5 hrs., 24 hrs., 24 hrs.... this cycle is repeated. As soon as the pump
stands in at least 4.5 cm water, the pump is ready for operation again.
Leakage protection:
If there is leakage on the pressure side (e. g. a leaking pressure hose or
connecting device), the pump automatically switches on and off in short
intervals. When the pump switches on and off more frequently than 7 x in
2 min. (with a leakage less than 90 l/h), the pump switches completely off.
When the leakage on the pressure side is eliminated, the pump must be
unplugged and plugged in again in order to be operational again.
