Signals for the EP applicator

For controlling the applicator the signals air stream, cylinder valve and blow on are necessary.
After a product signal has occurred the labelling cylinder valve is switched active after the delay
STAD. However if at this time the applicator is not in the home position then error message
E__2 is generated. After the delay time APT1 the blow on valve is switched active for the time
APT2.
When APT2 is completed both the labelling cylinder valve and the blow on valve signals are
switched inactive. If the control does not read the home position in the time given - 3* (APT1+
APT2) - than the error message E__2 is generated.
