1. MAKE THE FACTORY PARAMETERS RESET BEFORE STARTING THE INVERTER (parameter
SET.F at page 11 of the Manual)
2. RESTORE MANUALLY THE SPECIFIC PARAMETERS OF THE SYSTEM
3. DO NOT RE-CALIBRATE THE PRESSURE SENSOR, IT IS FACTORY-CALIBRATED
CALIBRATION OF THE PRESSURE SENSOR
-
You need an
auxiliary gauge
near STEADYPRES
-
bring the system (and STEADYPRES) pressure to zero (0 bar)
-
Start the calibration
of the pressure sensor according to the diagram below.

STARTING
(for 10 sec.)
Press simultaneously the 4 buttons, within the 10 seconds of
STARTING.
ZERO
Check
on the gauge that the pressure of the system is ZERO
Press the button SET/TEST
to confirm the zero pressure
SP 5.0
Start the pump by pressing START button
;
the pump starts at
the minimum frequency
SP 5.0
Increase the frequency of the pump by pressing the button
until you reach the required pressure of 5 bar
If the pump is not able to reach 5,0 bar
, reduce the required pressure
by pressing the button
(e.g. to 4 bar)
SP 4.0
Check
on the gauge that the pressure of the system is that required by
the inverter (e.g. 4 bar)
Press the button ENTER
to confirm
F hi
Press again the button ENTER
P_3.5
The inverter re-starts in automatic mode,
the sensors calibrated.
FITTING THE EXPANSION BOARD
- Switch off power to the inverter and wait 2 minutes for the capacitors discharge
- Open the back cover as shown in the figure on next page
- Insert the flat cable of the expansion board (see picture on next page) on the mating
connector mounted on the power board of the inverter
