BASIC PARAMETERS for the configuration of the inverter.
BASIC
They must be set during installation.
ADV ADVANCED PARAMETERS for the configuration of the inverter.
INSPECTION PARAMETERS: they display the hours of work, the number of starts, the
INSP
alarm logs, etc.
The test mode allows to start and stop the pump manually and change the frequency in
TEST
steps of 1 Hz. It also allows to check the operating parameters.
ATTENTION: in manual operation some of the automatic controls are disabled, and the
operator must avoid any erroneous manoeuvre.

(constant)
Sets the full scale of the pressure sensor
10-16-25-40 Bar
Sets the motor nominal output current from
the inverter (nominal current of the motor)
Sets the frequency below which the flow is
considered to be lower than the minimum
operation flow
Sets the direction of rotation of the THREE-
PHASE motor (clockwise / counter-
clockwise)
ADVANCED PARAMETERS (ADV)
Description
Sets the pressure between the SET and the
actual pressure of restart
Sets the minimum pressure value
(expressed as % of the SET pressure) that
must be reached at zero flow, in order not to
have a dry running alarm.
Defines the function of each inverter unit
(STANDALONE / MASTER / SLAVE)
Sets the speed of response of the inverter to
pressure variations
