a Flyer input. Flyer recognizes this input transition, sets an output bit to indicate the laser is on, and then
marks the part. After the mark is complete, Flyer clears an output bit signaling the conveyor to start and
run until another part is in place. Flyer then waits until another ‘start mark’ signal is received. The digital
I/O capability of SYNRAD’s FH Flyer marking head enables this kind of automated process control. Refer
to the WinMark Pro Laser Marking Software User Guide or our Laser Marking FAQ on the WinMark web
site (http://www.winmark.com) for details on configuring a basic automation sequence.
