装置の電源を入れると、制御室内のデータロガーに「異常警報」が発生しました。
装置からの信号を確認したところ、次のことがわかりました。
装置正常状態：「異常」信号発信 → 制御室内で警報発生
装置異常状態：「異常」信号停止 → 制御室内で警報非発生
つまり、装置からの信号が正常状態と異常状態で逆になっています。
装置内のリレー端子や、データロガーに問題はありませんでした。
先月行なったソフトウェア更新により、設定が変更されている可能性があるかもしれません。

When I turned on power of device, "warning of error" occurred at data logger in control room.
I checked the signal from the device, and found the followings.
Condition of device without error: Signal of error occurs. ⇒ Warning occurs in the control room.
Condition of device with error: Signal of error stops. ⇒Warning does not occur in the control room.
Namely the signal from the device is opposite by the condition without error and with error.
I found a problem at neither relay terminal within the device nor data logger.
The setting might be changed by updating of software conducted last month.

When I turned on the equipment “abnormal apart” occurred in the data logger in the controll room.
I checked the signal from the equipment and I found out the following thing.
Equipment normal condition: “abnormal” signal transmission→ Alarm occurred in the control room
Equipment abnormal condition: “abnormal” signal stopped→ Alarm didn’t occur in the control room
This is being said, it makes it the other way whether the signal from the equipment is normal or abnormal.
The relay terminal or data logger inside of the equipment had nothing wrong.
Maybe the setting has changed due to the software updates implemented last month.

Once the device is turned on, "Abnormal warning" occurred on the data logger inside the control room.
As we confirmed the signal from the device, the following were found:
Device under normal condition: "Abnormal" signal dispatched --> Warning occurs inside the control room
Device under abnormal condition: "Abnormal" signal termination --> Warning does not occur inside the control room
In other words, the signal sent from the device are mixed up under the conditions of normal and abnormal.
No issues were found with the relay terminal or data logger inside the device.
Due to the software update performed last month, the setting might be possibly modified.
