Setpoint pressure pre-selection
pA/pB remote contact:
An input contact provides the signal to switch
from the system setpoint pressure pA to pB.
Master control of compressors regulated
by pressure switch
There are two possibilities of linking to a
machine regulated by pressure switch:
On machines with the same FAD,
SIGMA CONTROL 2 controls the pressure
switch via a floating relay output.
On machines supplying an unequal FAD, the
pressure ranges are matched to each other.
