9.3. How to set up the operating limits for SLAVE-ONE modules (only SLAVE-SV version)
The following procedures allow to set up the AC voltage limits, within which the 0-10 Vdc control signal is automatically
controlled.
MIN Vac
limit
It allows to set up manually the minimum AC output voltage
supplied to the fan, from 20% to 90%, and permits to check:
- the correct phase-cutting of the controller
- the Cut-OFF set up
Set up of 'MIN VAC out' voltage value:
1) move the Jumper J3 in ON 1 position;
2) turn the trimmer from ’1’ position, until reaching the desired MIN rpm voltage
value; now the load is always supplied starting from the determined MAX AC
voltage limit
Cut-OFF
limit
It determines the value of minimum AC voltage to be
supplied to the fan in automatic operation (from 25% to
80%): this prevent the fan to be supplied with a lower AC
voltage, which would be not enough to give an adequate
torque for keeping the fan rotating.
Set up of 'CUT-OFF' AC voltage value:
1) move the Jumper J3 to ON 1 position;
2) turn the trimmer from ’1’ position, until reaching the desired MIN rpm
voltage value
3) turn the Jumper J3 back to the ON 2 position
now the load is supplied starting from the CUT-Off value
MAX Vac
limit
It determines the value of maximum AC voltage to be
supplied to the fan in automatic operation (from 100% to
20%), in order to limit the maximum airflow rate or the fan
noise at MAX rpm.
It is factory preset at the maximum value of ‘10’,
corresponding to the 100% of the control value.
Set up of 'MAX out' voltage value:
1) jumper the inputs IN and +10V: the AC voltage output is at 100%
2) turn the trimmer MAX out from position ‘10’ up to the desired value of MAX
AC voltage limit (ex.: 80%);
3) remove the jumper between IN and +10V : in automatic operation, the MAX
voltage limit supplied to the load corresponds to the determined AC output
voltage limit

(*) move the selection jumper in order to pass from
the Cut-Off limit to the MIN out limit; always
check the difference between VAC values, as shown
in the table below
