19. LOADING AND INSTALLATION
(1) System design circuit example
The procedures used to switch on the power supply are indicated below.
AC system
1) Switch the power supply ON.
2) Set the CPU module to RUN.
3) Switch the start switch ON.
4) The output devices are driven in accordance with the
program when the magnetic contactor (MC) comes ON.
AC/DC system
1) Switch the power supply ON.
2) Set the CPU module to RUN.
3) Switch RA2 ON when the DC power supply starts.
4) Set the timer (TM) to "ON" upon 100% establishment of DC power
supply.
(The set value for TM shall be the period from turning "ON"RA2 to
100% establishment of DC power supply.Set 0.5 seconds for it.)
5) Switch the start switch ON.
6) The output devices are driven in accordance with the program
when the magnetic contactor (MC) comes ON.
(When a voltage relay is used for RA2, the timer in the program
(TM) is not necessary.)
Interlock circuit
Constructs external interlock
circuits for opposing
operations such as forward
and reverse rotation, and
parts that could cause
machine damage or accidents.
Switches the power
supply to output devices
OFF when the system
stops:
At emergency stops
At stops on reaching a limit

The setting for TM
is the time taken
to establish the
DC input signal.
