Mode of operation
The "singlesheet" output signals that an object is within
the detection range. This output may be used to check for
presence.
A detected double sheet is
signaled at the "double
sheet" output.
In the standard mode, 2-layer
paper sheets with weights
between approx. 40g/m²
and approx. 400g/m² are
detected without additional
calibration.
With the "teach-in", the
measurement range limits
can be expanded to between
approx. 20g/m² and approx.
800g/m².
The calibration process is
started by applying a high
signal at the "teach-in" input.
Calibration is performed
either directly on a medium if a sheet is in the detection
range at the calibration time or calibration is performed
automatically if a medium is
inserted into the detection
range after the calibration
time.
The calibration process is
concluded after approx.
100ms.
When switched back on, the
sensor again functions in
standard mode
