(3.3) Pressure reading test: this displays the current pressure in the system. It can be used after the pressure sensor
Test
has been calibrated, to check that it is operating correctly. The value displayed corresponds to the real pressure in
5.0 BAR
the system, as displayed on the main screen.
(3.4) Flow switch reading test: this displays current flow switch value. It can be used after the flow sensor has
Test
been calibrated. to check that it is operating correctly. With the valve completely closed (no flow), the value
Flow 0
s.00
displayed must be close to zero.
(3.5) Software release: version of the device software
Sw.Rel.
1.00.00
(3.6) Power supply timing: this displays the number of hours the inverter has been powered . This is useful when
Sup.Time
checking whether the warranty period has elapsed.
00000 H
Pum.Time
(3.7) Pump operating time: this displays the number of pump operating hours . This is used . to compare the
00000 H
number of pump operating hours with hours of active power supply
Last (3.8) Last error: this displays the number of the last error that occurred in the system. This can be used to trace a
previous shutdown error that has already been reset by the user.
err. 1
(3.9) Pump start-up number: To Display the total number of starts carried out by the electric pump connected.
Start n°
00000
(4.0) Voltage boost at 0 Hz: This value indicates the percentage of voltage increase at 0 Hz to compensate for stator
V boost
losses. An increase to this value will increase voltage to the motor when the frequency drops.

D.R.del.
(4.1) Dry run: this sets the dry running protection intervention delay. Increase this value if the intake pipes are very
30 s
long or with pumps which have long priming times.
(4.2) Maximum starts per hour: Sets maximum number of pump starts in an hour. To disable the protection, press
Starts
the key until the word "OFF" appears.
Max/H.OFF
(4.2) 24 H anti-seize protection: this enables or disables protection against pump seizing in the event of prolonged
24HProt
inactivity. If activated, and unless the system makes any requests, this function performs a pump start every 24 hours
OFF
to prevent the mechanical components from seizing (hydraulic seal).
(4.3) PWM dead times: this sets the deadtime between two switch changes (IGBT) on the same branch. It may be
necessary to modify this parameter in order to correct the average output voltage from the inverter when the
PWM dt
switching frequency is changed. Contact the manufacturer for further information and for assistance in selecting the
40x125ns
most appropriate value.
