S6040A1003 AIR FLOW SWITCH
MOUNTING
The S6040A1003 Air Flow Switch (with separate paddle) is
mounted in the vertical position (i.e. with the switch box at the
top).
In order to avoid air turbulence and paddle instability, the
device should be installed in straight duct runs having a
length of at least 5 times the duct diameter both upstream
and downstream from the location of installation.
The device must be mounted with the seal plate (included in
the package) through an approx. 20-mm hole in the duct. The
device must be fixed with two screws (included in the
package.) The paddle must then be mounted with a screw on
the shaft inside of the duct.
NOTE: The flow switch is factory-set to the min. flow rate.
To adjust the device to other levels, turn the adjustment screw clockwise. Because of the risk of
breakage at air speeds greater than 5 m/s, when
installed in ducts in which high air speeds are
expected, the paddle must be cut off along the two
markings. When the paddle is narrowed in this way,
the minimum switch point is increased from 1 m/s to
2.5 m/s.
SWITCH-POINT ADJUSTMENT
Min. switch point: approx. 2.5 m/s; reset point: 1 m/s.
Max. switch point: approx. 9.2 m/s; reset point: 8.0 m/s.

NOTES:
1) THE MIN. SWITCH POINT IS ADJUSTED TO 1 M/S. IT
CHANGES TO 2.5 M/S WHEN THE PADDLE IS COMPLETELY
CUT OFF ALONG BOTH LINES.

THE PADDLE MUST BE COMPLETELY CUT OFF ALONG BOTH
LINES.

Connect the red and the white contacts. The contact redwhite opens when the flow drops below the switch point.
When the flow is absent, the contact red-blue closes and can
be used as a signal or alarm contact.
