10. Troubleshooting

10.1 Troubleshooting procedure

If a trouble occurs, determine whether the cause lies in the mechanical side or in the

control system (PLC) side. A problem may cause a secondary problem, therefore, try

to determine the cause of trouble by considering the whole system.

If the problem is found in the T1-16S, check the following points:

PWR (power) LED Follow the procedure in

10.1.1 Power supply check

Lit

RUN LED Follow the procedure in

10.1.2 CPU check

Lit

User program Follow the procedure in

10.1.3 Program check

Normal operation

Input operation Foll ow the procedure in

10.1.4 Input check

Normal operation

Output operation Follow the procedure in

10.1.5 Output check

Also refer to section 10.1.6 for environmental problem.

!CAUTION 1. Pay special attention during the troubleshooting to minimize the risk of

electrical shock.

2. Turn off power immediately if the T1 -16S or related equipment is

emitting smoke or odor. Operation under such situation can cause fire

or electrical shock.

3. Turn off power before removing or replacing units, modules, terminal

blocks or wires. Failure to do so can cause electrical shock or damage

to the T1 and related equipment.

4. Contact Toshiba for repairing if the T1-16S or related equipment is

failed. Toshiba will not guarantee proper operation nor safety for

unauthorized repairing.
