Material loop size adjustment (droop sensor)
If the default settings are not appropriate and the distance from the sensor to the material
loop needs to be adjusted, use the index plunger
and/or loosen or tighten the small black
screw on top of the sensor
.
The index plunger allows adjusting the vertical alignment of the detection by changing the
angle of the droop sensor. To do so, pull the knob, rotate, and release in one of the other holes.
The small, black screw allows adjusting the sensor’s sensitivity.
Turn to the right to increase
sensor sensitivity and to the left it to reduce sensor sensitivity. We recommend starting at
maximum sensitivity, and, if necessary, then turning the screw little by little to the left until the
sensor detects the material as required for optimal unwinding and feeding on the conveyor.
2.2.3.3.3
Set point learning (tension bar)
If the set point is incorrect, the unwinder may feed slowly or not feed at all when the tension
bar is being used. This requires a reset of the set point position.
1.
Allow the tension bar to hang free to clear the current tension bar set point.
2.
Power on the unwinder.
3.
Press and hold the
System ready
and the
Automatic/manual edge detection and tracking
buttons for 10 seconds. The system will flash orange/blue, then green, to indicate the
current set point has cleared.
4.
Reboot the unwinder to learn the new set point.
