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 program when
the magnetic contactor (MC) turns
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] Switch the timer (TM) ON when the DC power
supply reaches working voltage. (The set value for
TM must be the time it takes for 100%
establishment of the DC power after RA2 is
switched ON. Make this set value 0.5 seconds.)
[5] Switch the start switch ON.
[6] The output devices are driven in accordance with the
program when the magnetic contactor (MC) comes
ON.
(If a voltage relay is used at RA2, no timer (TM) is
necessary in the program.)
