NOTES
A board transfer occurs when a board is available (contact closed) and the machine is ready (contact closed).
The Board Available signal and Machine Ready signal can occur at anytime, but board transfer does not occur
until both contacts are closed.
The Board Available signal remains closed until the board has left the machine.
The Machine Ready signal remains closed until the board has arrived at the next machine.
