Underload (Imin)
Current at which the underload protection trips (switchable "OFF" or adjustable from
0.5 to 21 Amps for V1Z models and from 0.5 to 30 Amps for V1Z-F models).
The underload trip time is 4 seconds, except during start-up, which is 20 seconds to
allow the pump to prime correctly.
●
Underload setting (Imin)
The I.min setting must be turned fully left. [
1
Close the discharge valve (*).
2
Start the pump in manual or automatic mode using the remote
control contact via a control device (pressure switch, fl ow switch,
etc.) or via by making a jump connection between terminals 3-4.
Observe the current consumption indicated on the display.
3
Set "Imin" at least 0.2A above the observed current (see next
page).
4
Verify that the underload is detected and that it stops the pump.
5
Open the discharge valve.
6
Select the desired restart time.
(*)If there is no possibility to close the discharge valve on site, then
set the parameter Imin 25% below the nominal value (In) of the
pump. Once the thermal protection is correctly set, make sure that
it is activated in case of lack of water.
