 INTRODUCTION TO PROGRAMMING:
KEY DESCRIPTION
Left-hand arrow: this scrolls back through the menu pages
Right-hand arrow: this scrolls forwards through the menu pages
On-Off/Reset: this switches the device from stand-by to operation mode and resets the unit in the event of
alarms and/or faults.
"+" key: this increases the value of the parameter currently shown on the display;
"-" key: this decreases the value of the parameter currently shown on the display;
"AUTOSET": this starts the self-setting procedure for the stop frequency function
INITIAL CONFIGURATION FOR SINGLE DEVICE INSTALLATION
In the case of single installations, power up the device and follow the instructions for initial configuration as
described below.
On initial activation, a welcome screen is displayed and when any key is pressed, a guided configuration procedure
is started up, enabling the entry of the main parameters required for standard operation.

Modify the value of parameters using the keys + and – then confirm the
entry by pressing the central key to move to the next parameter. The
parameters to be configured are displayed in the following order:
Parameter 2.0 – Serial address: in the case of single installations with a
single pump, leave this value at 1. If a pressurisation unit with multiple
pumps is installed, set the number of the device in the serial bus from 1 to 8.
1
Each device must have a different serial address number to be distinguished
from the others.
Parameter 2.1 – Pressure sensor serial address: in the case of single
installations with a single pump, leave this value at 1. If a pressurisation unit
with multiple pumps is installed, set the number of the device to which the
1
pressure sensor and any other auxiliary inputs are connected.
The value must be the same for all devices as only one pressure sensor
transmits the signal to all inverters.
Parameter 1.0 – Motor current: set the rated motor current as stated on
the pump electrical data plate. In the case of multiple installations with
several pumps, the value must be set for each inverter, as the pumps may
0.5A
have different characteristics.
Parameter 0.0 – Pressure set point : set the constant pressure value that
the inverter must maintain in the system. The pump rotation regime is
varied according to the flow rate demand of the system, to maintain
pressure at the set value.
