8.1.1 DIL switches
The amplifier module is provided with 2 DIL switches (S1 and S2), which are located
on the printed-circuit board within the module housing.
The DIL switches are used for configuring the
pressure command value
and
the
actual pressure value
as “voltage input” or as “current input” as well as the
pressure switch thresholds
