Red cable
=
+12 to 24V supply
Black cable
=

Yellow cable =
1.6 to 10v DAC control output
Green pipe
=
Positive pressure input
Black pipe
=
Negative pressure input or static pipe

Installation
The SPC-01 controller is provided with two mounting slots suitable for M3 screws for mounting
onto a flat vertical surface. Although orientation is not critical for operation, it is suggested that
vertical mounting is generally used.
6.
