10.2 Applicator modes
The machine is able to dispense the label direct on the passing product. There is also the
possibility to drive without any external control a wide range of applicators.
10.2.1 Signals for direct dispense
For direct dispensing the airstream signal can be used to control a pneumatic driven dispensing
edge. The start of the airstream signal (= motor run signal) could be behind the start of the
dispense motor, adjusted with the function APT3. The signal is switched inactive, when the
label dispense has been completed. Also the stop could be adjusted with the function ASTP to
switch inactive before or behind the dispense motor stop.
