3月2日の20:29~21:00に、JB chamber内で発生した、温度異常警報のトラブルについて、社内の技術部門にて原因の分析と調査を行いました。トラブル原因と対策について、弊社としての見解を下記にまとめました。
主な原因はtwo way valveが損傷し、動作に不具合が発生し（バルブon-offの調整が出来ない）、chamberの室温が変動したと思われる。
具体的には、two way valveのモーターが損傷した可能性があると思われる。

We analyzed and investigated the root cause of abnormal temperature warning which occurred in JB chamber at 8:29 pm to 9;00 pm on March 2nd with the technical department. We have summarized the cause of the trouble and countermeasures based on our observation as follows:
The main reason is that the two way valve was broken and it caused malfunction (valve on/off did not work), so the room temperature of the chamber changed. Specifically, the motor in the two way valve could have broken.

Concerning the trouble of abnormal temperature alarm which has occurred within JB chamber between 20:29- 21:00 on March 2, an analysis and an investigation for the cause took place by the internal technical department. The below summary shows our understanding about the cause and measures for the trouble.
The major cause was believed to be the damage of two way valve, performance malfunction occurred (on-off adjustment of the valve is not available), the room temperature of the chamber has changed.
To be more specific, a damage appears to have occurred with damaged two-way valve motor.

From 20:29 to 21:00 on March 2, the company's technical department analyzed and investigated the cause of the temperature abnormality warning problem that occurred in JB chamber. Our opinion on the causes and countermeasures of troubles is summarized below.
The main cause seems to be damage to two way valve, malfunctioning operation (valve on-off cannot be adjusted), and chamber room temperature fluctuating.
Specifically, it seems that the motor of two way valve may have been damaged.

送って頂いた写真を見るとﾓｰﾀｰにabrasion powderが付着しているが、動作過多によることが原因であると思われる。
異音・発熱もしていると報告があるので、ギア内部が損傷している可能性が高い。
正確な原因調査をするには一度弊社に送って頂き、弊社からメーカーに送って、調査する必要がある。その場合の費用は御社負担となる。
現状は通常動作をしているが、再発する可能性があるので、早急にtwo way valveを交換し、再度水温調整する必要がある。

When we see the picture you sent to us, we see abrasion powder on the motor, but this could be because of the heave load of the motor.
The report said that some strange sound and abnormal temperature are also observed, the inside gear highly probably broken.
In order to specify the root cause accurately, you need to send the motor to us and we need to send it to the manufacturer and have them investigate it, The cost needs to be covered by you.
Currently it is working as usual, but the problem could happen again. So, we need to replace the two way valve and adjust the water temperature again.

If you look at the photo you sent me, the abrasion powder is attached to the motor, but it seems to be due to over-operation.
There are reports of noise and heat generation, so there is a high possibility that the inside of the gear is damaged.
In order to investigate the exact cause, it is necessary to send it to us once, send it from our company to the manufacturer, and investigate. In that case, the cost will be borne by your company.
It is currently operating normally, but it may recur, so it is necessary to replace the two way valve as soon as possible and adjust the water temperature again.
