■ Repeat shift circuit
Turns ON every output for a second sequentially. Sets 1000 to 2008 (ON for 1st
scan only at startup) and shifts outputs from 7500 to 7504 every second at T001.
When 1005 turns ON, 1000 is set and the same sequence as above repeats.

■ Synchronous shift register
Turns ON input relay 0002 to reset the shift register (1000 to 1010) when the data
