TROUBLESHOOTING

8.1 General information

If any trouble occurs with the control system, perform the

preliminary check described below and then proceed to the

troubleshooting described later.

The following preliminary check is very important when you

consult with service engineer.

Preliminary check:

Was any alarm displayed on the controller?

If yes,

identify the cause of alarm.

Also examine previous alarms through the LED readout in

mode (refer to "Alarm/warning table").

If fuse was blown out,

identify the phase in which the

blown out fuse was used (control circuit power supply

fuse).

3. Is the trouble or failure reproducible?

4. Are ambient temperature and panel inside temperature nor-

mal?

5. When the trouble occurred (during

ration,

or steady-speed operation)?

What was the speed?

ion,

le-

6. Is direction of rotation correct?

7. Did instantaneous power failure not occur?

Does the same trouble occur in a specific operation, or

when a specific command is given?

9. How frequently occurs the trouble?

10. Does the trouble occur when load is applied, or when load

is removed?

11. Was any part replaced or any provisional remedy done?

12.

How many years have been used the control system?
