It detects pressure be-
low a pre-set value and
for a pre-set period in the
ADVANCED PROGRAM-
MING MENU. The minimum
pressure helps to detect
a dry-run operation or
pumps running far from its
best efficiency point. This
alarm is reset automatically
as soon as the pressure
exceeds the limit value.
A02

OVERLOAD
Overcurrent alarm is acti-
vated when the nominal
