14.4 Troubleshooting

This section describes errors that may occur during system operation, how to locate
the errors, and measures against the errors.
Check the LEDs of the module during troubleshooting.

14.4.1 Basics of troubleshooting

In order to increase the reliability of the system, resuming the system operation
promptly after correcting a problem is one of the important factors as well as using
reliable devices.
To promptly start up the system, the trouble cause must be located and eliminated
correctly.
The basic three points to be followed in the troubleshooting are as follows.

(1) Visual inspection

Visually check the following.
1) Behavior of the safety controller and other connected devices
2) Applicability of the power supply
3) States of input and output devices
4) Installation states of the CPU module and safety I/O modules
5) Wiring (Power cable and I/O lines)
6) Display status of all indicators (such as MS LED and CV LED)
After checking 1) through 6), connect the Setting and Monitoring Tool
and monitor the operating status and logic processing of the MELSEC-
WS safety controller.

(2) Error checking

Check how the error status changes by operating the following to the
safety controller.
1) Turn on or off the power supplied to the memory plug.

(3) Narrowing down the scope for identifying trouble cause

Estimate the troubled part based on the check results of the items (1)
and (2) above.
1) MELSEC-WS safety controller or external devices
2) CPU module or others
3) Configuration
