6. OPERATION

n PRELIMINARY INSPECTION [POWER OFF]
Incorrect connection of the power supply terminal, contact of the DC
input wire and power supply wire, or short-circuiting of output wires
may result in serious damage. Before applying power, check that the
power supply and ground terminals are connected correctly and input/
output devices are wired properly.
NOTES The dielectric withstand voltage and insulation resistance
test of the PLC should be measured in accordance with the following
procedures.
1. Remove all input/output wires and power supply wires from the PLC.
2. Connect a crossing wire to each of the PLC terminals (power supply
terminal, input terminals and output terminals) except the ground
terminal.
3. For the dielectric withstand voltage test of each terminal, refer to
the generic specifications for the product. Measure the dielectric
withstand voltage and insulation resistance between each terminal
and the ground terminal. Dielectric withstand voltage: 1.5kV AC or
500V for 1min (The terminals vary in dielectric withstand voltage.)
Insulation resistance: 500V DC/5M or more.

n WRITING OF PROGRAM AND PROGRAM CHECK
[POWER ON AND PLC STOPPED]
1. Turn on the PLC power.
Make sure that the RUN/STOP switch of the PLC is set to STOP,
and turn the power on.
2. Check the program.
Check for circuit errors and grammatical errors with the program
check function of the programming tool.
3. Transfer the sequence program.
Write the program to the PLC with the programming tool.
4. Verify the sequence program.
Verify that the program has been correctly written to the PLC.
5. Execute PLC diagnosis.
Check for errors in the PLC main body with the PLC diagnostic
function of the programming tool.
n METHODS OF RUNNING AND STOPPING
FX3S PLCs can be started or stopped by any of the following three
methods. Two of the methods can be combined. The RUN/STOP switch
is located under the peripheral device connector cover.
1. Operation with built-in RUN/STOP switch
Operate the RUN/STOP switch on the front
panel of the main unit to start and stop the
PLC (refer to the right figure). Turn the switch
to RUN, and the PLC will start. Turn it to
STOP, and the PLC will stop.
