4.4  Reset Operation

For the CPU module, the RUN/STOP/RESET switch of the CPU module is used to switch 
between the "RUN status" and "STOP status" and to perform "RESET operation".
When using the RUN/STOP/RESET switch to reset the CPU module, moving the RUN/
STOP/RESET switch to the reset position will not reset it immediately.

Hold the RUN/STOP/RESET switch in the RESET position until reset processing 
is complete (the flashing ERR. LED turns off).
If you release your hand from the RUN/STOP/RESET switch during reset 
processing (during rapid flashing of ERR. LED), the switch will return to the STOP 
position and reset processing cannot be completed.

Perform reset operation with the RUN/STOP/RESET switch as shown in Figure 4.4.
