Vset before switching off the power to the pump. It is possible not to give a value to Thold (three
dashes shown) which means that no self switching off will take place (the user will have to stop the
powering by acting on START/STOP button).

In order to modify setup values, press shortly MENU/ENTER.
A blinking cursor will indicate which parameter is currently being edited.
By shortly pressing arrow keys you will increment or decrement by 1 the value. A long pressure on
an arrow key will change the edited value fastly.
Pressing MENU/ENTER is the action to move to the next parameter. After the last value pressing
MENU/ENTER saves the values.
START/STOP activates and stops the power supply: pressing the button once starts supply and
pressing it again stops the supply at any time.
START/STOP is not enabled while editing parameters.
When you turn off and turn on NEG POWER MINI, the last settings and used parameters are
presented and you can use them again pressing start button without any other change.
So it is easy to choose the settings one time and use repeatedly on the same system; if you change
system or usage conditions you can choose the new appropriate settings.
During power supply to the pump, the
Run
screen is shown.
The second line reports the
temperature
of the pump (if available).
The third line shows the value of
Vset
as chosen in the Setup menu and alongside

indicating
the number of minutes from the beginning of the power supply to the pump.
Fourth line identifies the current output supply condition “
Out
” and we can read both voltage and
current.
After the end of power supply, whether obtained by pressing STOP or by self switching off, the
Standby
screen is shown again.
