IMPROVEMENT MADE TO PREVENT MALFUNCTION CAUSED
BY IMPERFECT CONTACT ON FIXING JUNCTION PWB.
It was found in the field that the soldered section of the FASTON terminal on the Fusing
Interface PWB was cracked, causing a malfunction (H4, etc.). This is to inform you of the
countermeasures taken to solve this problem.
To prevent this problem from occurring, replace the Fusing Interface PWB at the earliest
opportunity such as periodical inspection, maintenance work or a service call.
AR-250/280/285/286/287/335/336/337/405/407/505/507
The soldered section is cracked due to stress produced when the tab terminal is
connected/disconnected. As a result, imperfect contact occurs at the section due to thermal
stress produced during operation, causing a malfunction.
To reinforce the PWB, the material of the Interface harness PWB is changed to a glass fiber
filled double-sided PWB, and soldering is performed on the front and rear sides by making a
through hole.
