· Compare the maximum values specified in these operating instructions with
your actual application (e.g. operating media, pressures, forces, torques,
temperatures, masses, speeds, operating voltages, flow rates).
· Take into consideration the ambient conditions at the location of use.
· Please comply with national and local safety laws and regulations.
· Remove all transport packing such as protective wax, foils (polyamide), caps
(polyethylene), cardboard boxes (except for the sealing elements of the
pneumatic connections).
The packing is intended for recycling (except for: oiled paper = other waste).
· Use the product in its original state. Unauthorized modification is not permitted.

Installation
4.1 Mechanical assembly
The mounting position is horizontal
±
5 %. Fasten the SFAM as follows:
Fig.3
Note
Information about fitting module connectors, sub−bases and mounting brackets
can be found in the operating instructions enclosed with the relevant
accessories.
Combination with service units of the MS series
The SFAM may only be combined with service units of the MS series which have a
pneumatic connection of at least
½
".
If combined with an existing service unit of the MS series:
1. Please note the direction of flow.
2. Install the SFAM only after service units which conform with the degree of
filtration (air quality class 5.4.3.: 40m residual dust, +3°C pressure dew point,
1mg/m´ residual oil content).
Note
The SFAM must not be installed directly behind a pressure regulator or filter
control valve to comply with the set accuracies.
· Install after an MS
Ū
−LFR filter control valve or MS
Ū
LR pressure control valve
an MS
Ū
−FRM−1/2 distribution before the SFAM.
3. Remove the cover cap, if fitted, from the side to be combined (push upwards).
4. Place the module connectors type MS
Ū
−MV in the grooves of the individual
units. There must be a seal between the individual units.
5. Fasten the type MS
Ū
−MV module connectors with 2 screws.
4.2 Pneumatic connection
The air mass flow is routed to the connection where the sieve cartridge (on type
SFAM−
Ū
−M) or the starting stretch (on type SFAM−
Ū
−T) is situated. The air mass
flow is taken from the opposite connection.
In order to maintain the accuracy of the specifications, the SFAM must be supplied
via an inner connection diameter of at least 10mm or via a pneumatic connection
of at least
½
".

4.3 Electrical connection
Warning
Use only power units which guarantee reliable electrical isolation of the
operating voltage as per IEC/DINEN60204−1. Observe also the general
requirements for PELV power circuits as per IEC/DINEN60204−1.
Switch power packs are permitted, providing they guarantee reliable isolation in
accordance with EN60950/VDE0805.
Note
Long signal cables reduce the immunity to interference.
· Make sure that the signal cables are shorter than 10m.
Note
The binary outputs at pin2 and pin4 can be wired as PNP or NPN connections as
needed.
· Make sure that you also configure the binary outputs according to your wiring
