Chapter 8 Test Run, Monitoring and Maintenance

During maintenance, be sure to turn off the input power of PLC in case the actions to touch any terminal on
PLC, or insert and extract accessories (e.g., expansion ribbon cables) is required. Otherwise, electric shock,
short circuit, damaged PLC or PLC malfunction will be caused if the power is on.

8.1 Inspection After Wiring and Before First Time Power on

1. Before power on, clean all unnecessary objects such as iron chippings and screws, and remove the dust cover
sheet that surround the FB
2. Make sure that the input power and PLC required power is of the same type. When input power is AC power,
please pay attention to connect the hot wire (L) to the "L" terminal on PLC and the ground wire (N) to the "N"
terminal. Mistakenly connect to DC powered PLC or to terminals other than "L" and "N" will result in electric shock,
serious damage or malfunction.
3. Make sure the load power and PLC output circuits are consistent. Connection of AC power to transistor output or
DC power to TRIAC output will damage PLC or result in malfunction.
4. Make sure the DC24V input and polarities of SINK/SOURCE in transistor output are consistent with those of your
existing wiring. Any mismatch will result in failure of PLC input and damage to the output circuit.

8.2 Test Run and Monitoring

The FB -PLC provides a convenient feature to Disable/Enable the I/O points by whole or individually. Namely, while
S
PLC performs the normal logic scan operation and I/O refreshment, it does not update the status of the disabled input
points according to the actual external input. For the disabled output points, the result of logic scan can't override the
disable status of outputs, only the user can force the state to 'on' or 'off' in order to simulate its operation. The user only
needs to utilize the disable function combined with Monitor to achieve simulating the input or output via FP-08 or
WINPROLADDER and observe the result. Upon the finish the simulation, revert all the inputs or outputs to Enable state
will bring back normal operation. Refer the instructions of WINPROLADDER or FP-08 for the operation of RUN/STOP
PLC, Disable/Enable I/O and monitoring of I/O status and content of register.
The disable function is to let the input or output status out of PLC program control and switched to the
control of the user (tester) to freely set the disabled input or output to be ON or OFF. In normal PLC
operation, when dealing with input or output with safety issues (such as upper/lower limit of detected input
or output emergency stop), the user must make sure whether it can be disabled or overridden to ON/OFF
before starting the disable or override control, to avoid damage to equipment or harm to people.
