Reverse PEP
[156] Pattern of control signals over time for Reverse PEP
applicators.
A
Duration is determined by label length and dispensing
speed. „Airstream Support“ switching to low means the label
is dispensed.
B
Adjustable with “Blow on time”.
C
Duration t is determined by the backwards movement of the.
applicator. The application cycle ends when the home posi-
tion signal is high again
D
The output signal „Offline“ follows the input signal „Inhibit“.
E
The start signal is ignored because of the active „Inhibit“.
F
The end of „Cycle“ can be adjusted with “Dwell time” (usual-
ly, this function sets the end of the „Cylinder“ signal, in case
of the Reverse PEP, „Cylinder“ stays active up to the next
start signal, what means that the dwell time is ignored).
