P = X X X W
T = X X
Where:
P= XXX W is the current power supplied to the
pump
T=XX °C is the current temperature of the pump
XXXX Hz is the current frequency of rotation of the
pump. This value is set by default to 1350 Hz but
can be modified by the user according to needs,
proceeding as described in the "PROGRAMMING"
paragraph. The unit of measurement (HZ / Krpm,
default = Hz) is selected by the user from the
INPUT/OUTPUT->SPED menu.
If the SOFT-START function (PUMP SETTING
menu → SOFTSTART is active and the pump is
ramping, indication of the speed of rotation is
replaced with a bar-graph that indicates the soft-
start step in course and the total number of steps to
be performed.
On completion of the soft-start ramp, the bar-graph
is replaced with indication of the frequency of
rotation of the pump
Pressing twice, the following is obtained:
N O R M A L
I = X . X X A
Where:
NORMAL: indicates the operating regime
of the pump
XXXHz: see description "Pressing once"
Measures key
I=X.XXA: indicates the current absorbed by the
pump
V= XXX V: indicates the pump driving voltage
Pressing 3 times, the following is obtained:
X X X X H z

Where:
P= XXXW: indicates the current power supplied to the
pump
XXXHz: see description "Pressing once" Measures
key
x.xxE-yy mbar: indicates the pressure currently
measured by the gauge.
Other possible indications:
P = X X X W
P R A U G E
Where:
GAUGE_ERROR: gauge not connected or broken
P = X X X W
P R E S S U R E
Where:
PRESS UNDER: indicates that the pressure read is
below the minimum measurement threshold set (5
E-9 mBar)
P = X X X W
P R E S S U R E
Where:
PRESS OVER: indicates that the pressure
measured is above the maximum measurement
threshold set (1000 mBar)
The unit of measurement of the pressure can be
selected (GAUGE menu→Unit) from
"mBar","Pa","torr"
Pressing 4 times returns to the following screen
