Function and application
The SFAM is designed to monitor changes in flow and air consumption
for suitable
media in pipe systems or end devices in industry; suitable media
è
Technical specifications. The structural design enables autonomous operation
(SFAM−
Ū
−T) or combination with service units of the MS series (SFAM−
Ū
−M).
Measurement is carried out by means of a thermal procedure. The amount of heat,
which is drawn from a heated surface of the sensor by the medium flowing through
it, is calculated here. Through the amount of heat removed, the flow or accumu
lated air consumption is determined and shown on the display. The connection to
higher−level systems is made via 2 binary outputs (OutA/B) and one analogue
output (OutC). Switching points can be set for both binary outputs. For flow
measurement, switching points are possible for both binary outputs, and for accu
mulated air consumption measurement a consumption switch impulse for outputA
(OutA). The combination of accumulated air consumption measurement (OutA)
and flow measurement (OutB) is possible. The flow rate value is passed on via the
analogue output.

Conditions for the safe use of the product
Warning
Depending on the functioning of the machine/system, manipulation of signal
states may cause serious personal injury.
· Note that if the switching status of the outputs is modified in Edit mode, the
new status will be effective immediately.
· Activate the password protection (security code) in order to prevent the
unintentional change by unauthorized third parties
è
chapter5.4, section
Security code.
Warning
Use of the product in combination with prohibited media can result in personal
injury.
· Do not use the product in conjunction with inflammable gases, corrosive
gases, oxygen etc. The product is intended only for measuring the flow of
media, which are listed as suitable in the specifications chapter 11.
Important
Condensation water, oil mist, foreign matter and other dirt in the compressed air
can damage the product and cause incorrect measurements and functional
disorders.
· Make sure that the specified air quality class is maintained for the operating
medium
è
chapter 11 Technicalspecifications.
Note
Improper handling can result in malfunctions.
· Make sure that the following specifications are always observed:
