PEP Blow On
[155] Pattern of control signals over time for PEP Blow On
applicators.
A
Duration is determined by label length and dispensing
speed. „Airstream Support“ switching to low means the label
is dispensed.
B
The total duration of Cylinder is the sum of both durations t
1
and t
2
. The duration t
1
is setable by “Dwell time”; t
2
is setable
by “Blow on time” (see note C).
C
Can be adjusted with “Blow on time”.
D
Duration t
3
is determined by the backwards movement of the
applicator. The application cycle ends when the home posi-
tion signal is high again.
E
The output signal „Offline“ follows the input signal „Inhibit“.
F
The start signal is ignored because of the active „Inhibit“.
