Provide external
interlock circuits for
conflicting operations,
such as forward rotation
and reverse rotation,
and for parts that could
damage the machine or
cause accidents if no
interlock were used.

For AC/DC
1) Turn power ON.
2) Set CPU to RUN.
3) When DC power is established, RA2 goes ON.
4) Timer (TM) times out after the DC power reaches 100%. (The TM set
value should be the period of time from when RA2 goes ON to the
establishment of 100% DC voltage. Set this value to approximately 0.5
seconds.)
5) Turn ON the start switch.
6) When the magnetic contactor (MC) comes ON, the output equipment is
powered and may be driven by the program. (If a voltage relay is used at
RA2, no timer (TM) is required in the program.)
