A data bit that provides a means of checking for errors in the data stream.
PSIG:
A measure of air pressure (Pounds per Square Inch Gauge). 1 bar = 14.7 PSI.
Pneumatic:
Moved or operated by air pressure.
Product Delay:
The time delay before the tamp is extended (Tamp-On Mode), before the air blast is activated
(Air Blow Mode), or before extending the tamp and firing the air blast to apply a label (Tamp-
