- Working without the flow sensor
- In order to stop the inverter at zero demand
- At the first pressure setting you must define the SHUTDOWN FREQUENCY (= frequency
at the minimum working flow or shutdown flow)
- the "shutdown flow" must be proportionate to the size of the pump, and approx. 3% of
the pump max flow rate

- Until the working frequency is greater than the OFF FREQUENCY ( = no demand for
water), the inverter will maintain the pump turned on.
- When the working frequency drops below the OFF FREQUENCY ( = he water demand
has ceased), the inverter stops the pump.
- You can change the OFF FREQUENCY during operation, by pressing the arrows UP
and DOWN and repeating the cycle over.
BASIC PARAMETERS
description
Sets the constant working pressure in
the system.
Sets a second working pressure.
To activate configure parameter EI in
ADV. parameters.
Sets the motor rated current
at the inverter output (rated
current of the motor)
Set the direction of rotation of the
three-phase motor (CW / CCW)
OFF frequency (shutdown frequency)
instruction
Start the drive in the presence of a flow
demand (a valve system must be open)
Press simultaneously the keys UP and DOWN F 42 (example)
manually adjust the flow to the "shutdown
flow" (the flow to which I want to turn off the
pump)
Wait for the frequency to stabilize, and
confirm with the ENTER key
