Electrical / FF Connections
The FOUNDATION Fieldbus Sensor Communications Module (SCM-FF) combines integral switch relays for position
sensing with F
OUNDATION Fieldbus communications and pilot valve output drivers.
Pilot Valve Wiring
Single Pilot Valve
· The Orange (or Red) lead is terminated on V1+. (+ = Orange)
· The Black lead is terminated on V1-. (- = Black)
Dual Pilot Valve
· The open valve wiring to the V1 terminal (+ = Orange)
· The close valve wiring to the V2 terminal (- = Black)
FOUNDATION Fieldbus Wiring
The Fieldbus Segment Wiring is connected to the FF Terminals on the SCM. These terminals are NOT polarity
sensitive.
It is strongly recommended that FF wiring leads are not daisy-chained together and each drop provides
short-circuit protection.
Auxiliary Dry Contact
Attach dry contact wiring to the AUX terminals.

Flash Reset Button
When there is an active device alarm, the LEDs will blink. The Flash Reset Button will stop the flashing indications.
For testing of the pneumatics and calibration of the target assembly, a 9 to 32 VDC power supply can be
used with the calibration switch to open and close the valve without a fieldbus loop attached.
