TROUBLE-SHOOTING DIAGRAM

HOW TO TROUBLE SHOOT

1) In case of trouble, first check the equipment according to the pre-delivery check and periodic check procedures.

2) Conduct a test under simulated conditions, and investigate the symptom of trouble.

3) Repair the defect, and conduct a confirmatory test to make sure that the cause of the trouble has been removed.

4) When the symptom of trouble cannot be reproduced, set up conditions similar to those in which the trouble occurred, and conduct a test again.
