Operation of a Micro-Drip-
System:
The operation of a Micro-Drip-System is possible. Here, the maxi-
mum values stated in the accompanying manual of the Master
Unit 2000 are reduced. With Art. No. 1742, at least 90 l/h must be
taken as otherwise the leakage protection is activated.
4000/2 (Art. No. 1740):
Dry-Running Safety:
9
So that the pump automatically switches off when there is
noliquid to pump, the Float Switch
9
must be able to freely
move on the surface of the water.
Switch-off height:
If the water level (with the foot fitted) drops below the cut-out
level (approx. 25cm), the float switch
9
automatically switches
off the pump (Dry-Running Safety).
Switch-on height:
When the water level has risen over the cut-in height
(approx. 57cm), theFloat Switch
9
automatically switches
the pump on.
4000/2 automatic (Art. No. 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 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 (4x). In 1 hr., 5 hrs., 24 hrs., 24 hrs.... this cycle is repeated.
Assoon as the pump stands in at least 4.5 cm water, the pump
isready 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 3 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.
