alarm is trig- 0.0: Dis-

the alarm is
triggered, the
pump stops
and the ART
function is ena-
bled. SeeSpe-
cial functions on
page 39. Trig-
gering of the
alarm is de-
layed by the
amount of time
set in the

ter).

dP This parameter 0–99
is the value for
starting the
pump after a
stop, calculated
as a percent-
age of the re-
quired set point
value. Exam-
ple: SET
PRESS =
4.0bar dP =
90% (3.6 bar).
If the pressure
in the system
reaches the re-
quired pressure
of 4.0 bar and
there is no ad-
ditional con-
sumption, the
converter disa-
bles the pump.
As consump-
tion increases
and the pres-
sure decreas-
es, the convert-
er turns on the
pump when the

WARNING:
If the parameter EL=0 and MP=0, the
pump is not protected against dry run-
ning. The warranty does not cover dam-
age to the electric pump caused by in-
correct configuration.
• For motor cables longer than 30 m, it may be
necessary to increase motor current by 10%.
Check this in relation to the type of installation
and cable.
– Example: In=5A, set the parameter at 5.5A.
