Troubleshooting

procedure

If a trouble occurs, determine whether the cause lies on the

mechanical side or on the control system (PLC) side. A problem

may cause a secondary problem, therefore, try to determine the

cause of the trouble by considering the whole system.

If the problem is found in the T3 or in the T3’s I/O operation, check

the following points:

If the user program operation is

abnormal, follow the procedure in

6.4, Checking the program.

If an abnormalit/ is found in an

input module, follow the procedure

in 6.5, Checking input.

If an abnormality is found in an

output module, follow the procedure

in 6.6, Checldng ou^ut.

If the problem appears temporary and is synchronous with the

operation of the system/equipment, the external environment

(noise, voltage fluctuations, etc.) may have caused it. For details,

follow Section 6.7.
