supply module)
Diagram 10.2 System design circuit example
The power-ON procedure is as follows:
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 0.5s.)
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.)

interlocked with RA1
(run monitor relay)
Power supply module
Interlock circuits as
necessary.
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.
