OD sensor (ALX 92x)
OD = O utside D iameter (of the label roll).
Function
When the label roll is full, it interrupts the
light beam between the sensor [38A] and
the reflector [38B] in the sensor unit. As
soon as the label roll is unwound to a cer-
tain diameter, the light beam can reach the
reflector. The light barrier sensor then
sends a signal to the USI, which then acti-
vates a warning signal to a signal output.
The critical diameter is set by moving the
bracket [38C] which is fastened at the bot-
tom to the ALX base plate.

A switching range of around 1-2 m material
length may arise due to the label roll mo-
ving as it is being unrolled; i.e. the light bar-
rier sensor and thus the WARNING signal
may be activated several times within this
range.
