A threshold value for air consumption can be set with the consumption switch
impulse [CI]. If the set threshold value is reached, a switch impulse is emitted at
the output OutA for 100ms. With each switch impulse, measurement of the air
consumption is started again.

Preparing commissioning
In the base state, the product is in the RUN mode. The current measurement value
is displayed. The base state can be reached from other modes by:
pressing Edit button for 3 seconds or
passage of a monitoring time, timeout.
1.
Switch on the operating voltage.
The SFAM is in RUN mode.
2.
Check the settings of the SFAM

5.2 RUN mode
In the RUN mode
the measurement values for flow (in l/min or scfm)
the measurement values for air consumption (in m´, scf or l) and
the signal states of the switch outputs OutA, OutB (set, not set) are displayed.
Note
A flashing value means that the value was measured outside the permissible
measuring range.
5.3 SHOW mode
In the SHOW mode, the current settings for the switching outputs OutA and OutB
are displayed.
The SFAM must be in RUN mode.
· Pressing the A button (switching output OutA) or the B button (switching output
Out B) starts the SHOW mode for the respective switching output.
Note
If there are faults, pressing the A button/B button first displays corresponding
fault numbers.
· Repeated pressing of the A button/B button displays the settings of the
respective switching output one after another.
· When all settings have been displayed, the SFAM goes back into RUN mode
when the A button/B button are pressed again and displays the current
measurement value for the corresponding output.
As a result, the displays can also be changed via the SHOW mode to switch
between the displayed measurement values, such as with a combination of air
consumption measurement and flow measurement.
