–Only use the product if it is in perfect technical condition.
–Observe labelling on the product.
–Condensation, oil mist, foreign matter and other contaminants in the com-
pressed air can damage the product. Only use media in accordance with the
specifications Technical data.è
–This product can generate high frequency malfunctions, which may make it nec-
essary to implement interference suppression measures in residential areas.
2.2 Intended use
The SFAB is designed to monitor changes in the flow rate and air consumption of
gaseous media in piping systems or terminals in industry.
2.3 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can
evaluate the work and detect dangers. The qualified personnel have skills and
experience in dealing with electropneumatic (open-loop) control technology.
2.4 Range of application and approvals
Certain configurations of the product have been certified by Underwriters Labora-
tories Inc. (UL) for the USA and Canada. These configurations bear the following
mark:
Fig.1
UL Recognized Component Mark for Canada and the United States. Only for
connection to an NEC Class 2 supply. Raccorder Uniquement a un circuit de Classe
2.
Observe the following if the UL requirements are to be complied with in your
application:
• Regulations for complying with the UL certification can be found in the sepa-
rate UL-specific special documentation. The technical data listed there take
priority.
• The technical data in this documentation may show values deviating from this.

4.2 Functional principle
The SFAB uses a thermal measurement method. Here, the amount of heat drawn
from a heated surface of the sensor by the medium flowing past it is calculated.
Through the amount of heat removed, the flow rate or accumulated air consump-
tion is determined and shown on the display. The connection to higher-level
systems is implemented through 2 binary outputs (Out A/OutB) and one analogue
output. Switching points can be defined for both binary outputs. Switching points
for both binary outputs are possible for flow rate measurement, a consumption
switching pulse for output A (OutA) is possible for cumulative air consumption
measurement. The combination of cumulative air consumption measurement
(OutA) and flow rate measurement (OutB) is possible. The flow value is output
via the analogue output.
5 Assembly
5.1 H-rail (manifold assembly)
1. Maintain lateral distance x = 10 mm to earthed surfaces.
2. Hang SFAB in H-rail.
3. Press SFAB in the direction of the arrow.
ÄSFAB snaps into place.
5.2 Wall mounting
1. Maintain lateral distance x = mm to earthed surfaces.
