F3 - Middle diameter calibration - only for field calibration
Important
: Before calibrating, make sure that there are no objects other than the target in the
sensor’s action cone.
Position a known diameter reel in front off the sensor (diagram on page 12).
The red LED indicates the presence of the target:
-
if the red LED is off the target is present and calibration can be performed correctly
-
if the red LED is flashing the target is not detected and calibration is impossible
Connect a voltmeter to one of the sensor’s two analog outputs (blue wire or orange wire).
To start calibration make sure that the red LED remains constantly off then press
SET
; the red LED
will light up and the output voltage will increase starting from 5V.
Use the
ENTER
key to increase or reduce the voltage. When the output reaches the value calculated
using the formula shown below, press
SET
to confirm it. If calibration has been performed the red
LED flashes twice.

F4 - Maximum distance calibration (axis calibration) - only for lab calibration
Important
: Before calibrating, make sure that there are no objects other than the target in the
sensor’s action cone.
Position a stiff target (ex. cardboard) in front of the sensor. The distance between target and the
capsule has to be the same one which is between sensor and the reel rotation axis once sensor is
installed in its own working position (see diagram on page 13).
The red LED indicates the presence of the target:
-
if the red LED is off the target is present and calibration can be performed correctly
-
if the red LED is flashing the target is not detected and calibration is impossible
To calibrate, make sure that the red LED remains constantly off then press
SET
; if calibration has
been performed the red LED flashes twice.
Note
: rotation axis is the centre of reel shaft.
To select following function press
ENTER
key.
