CHAPTER 9 TROUBLESHOOTING

9.1 Troubleshooting

This section explains the troubleshooting for the cases where the count of input pulses
cannot be started and the input pulse count value is incorrect during use of the
QD60P8-G.

(1) When the RUN LED is turned OFF

Check item

Corrective action

Is the power being supplied?

Confirm that the supply voltage for the power supply module is
within the rated range.

Is the capacity of the power supply module adequate?

Calculate the current consumption of the CPU module, I/O
module and intelligent function module mounted on the base unit
to see if the power supply capacity is adequate.

Has a watch dog timer error occurred?

Reset the programmable controller CPU and verify that it is lit. If
the RUN LED does not light even after doing this, the module
may be malfunctioning. Contact the nearest branch office or
agency with a details of the occurring problem.

Is the module correctly mounted on the base unit?

Check the mounting condition of the module.

Is a module change enabled during an online module
change?

Refer to Chapter 8 and take corrective action.

(2) When the “ERR.” LED is turned ON

Check item

Corrective action

Is an error being generated?

Confirm the error code and take corrective action described in
Section 9.3.
