Festo – SFAM – 2017-09c English

Note

The compressed air must not contain ester oils.

Note

The SFAM must not be installed directly behind a pressure regulator or filter regulator to

comply with the specified accuracies.

 After the filter regulator MS…-LFR or pressure regulator MS…‐LR , build a branching

module upstream of SFAM.

–

Grid dimension 62: MS…-FRM-

½

–

Grid dimension 90: MS…-FRM-

¾

3. Place the module connectors type MS…-MV in the slots of the individual devices. Accordingly, a seal

is required between the individual devices.

4. Fasten the module connectors type MS…-MV with 2 screws.

4.2

Electrical connection

Warning

Only use power sources which guarantee reliable electrical isolation of the operating

voltage according to IEC/DIN EN 60204-1. Also observe the general requirements for

PELV power circuits according to IEC/DIN EN 60204-1.

Switched-mode power supplies are permitted, provided that they ensure reliable

separation in accordance with EN 60950/VDE 0805.

Note

Long signal lines pick up more interference.

 Make sure that the signal lines are always shorter than 30 m.

Note

The binary outputs at pin 2 and pin 4 can be wired as PNP or NPN connections as

needed.

 Make sure that you also configure the binary outputs according to your wiring
