The program is set up so that a rotary encoder (0000) controls execution of
SFT(10) through a DIFU(13), the rotary encoder is set up to turn ON and
OFF each time a product passes the first sensor. Another sensor (0002) is
used to detect faulty products in the chute so that the pusher output and HR
003 of the shift register can be reset as required.
