Dip-Switch setup
As you can see in the table below, the dither frequency can
be fixed from 80Hz to 220Hz. Dip switch 1-2-3 fixes the
various frequency.

Working
Once you have ended the above setup, the system is ready to control the valves.
Giving a set point to the input (~200mV when you use the potentiometer) the current flows to the solenoid starting from
the minimum current, fixed with the trimmer I MIN, to the maximum current, fixed with the trimmer I MAX, when the set
point is at maximum value.
Of course the current to the valves will rise or fall with the time imposed by the ramps, if you disabled the ramps, the
current will change immediately.
