Hello Nguyen,
You mean to mention Inductor OT alarm observed during installation time itself or after period of the installation?
How about the room environment where AccuSine PCS is installed and heat sink condition from inside the AHF.
Please refer inductor OT explanation as per below,
Inductor Temperature:
We have Thermal sensor inside the Inductor, on the failure, of this Thermal sensor, we will get this issue,
This temperature will not be displayed in the HMI, but, same will be continuously monitored by the Control board.
Here below are some of the possible reasons for this issue to pop-up.
If there was intermediate contact in the connectors.
If there was any damage or defect in the wire harness, which sense the Inductor temperature.
Unfortunately, the sensor inside the Inductor becomes defective then we need to replace the entire Inductor.
This is the first connectors that connects the Inductor thermal sensor and the wire harness.
This is the 2nd connector where the sense cable are connected with the Control board.
In general, we use to get Intermediate problem in the above connector.
As shown in the above image, please do the resistance measurement between the cables, the values should be as mentioned above.
Red and Black cables are used for Inductor temperature sensor measurements .
If you find any abnormalities, that is ,if the resistance values are measured in Mega ohms, then it is a problem.
We don’t have an option, 100% we need to replace the Inductor.
But if the measurement is well within the limit, then it can be due to intermittent contact between the cables in male and female connectors.
We call this as wire pull back issue, it is very rare, but, only that should cause this issue to happen.
I hope this can resolve your Inductor temperature issue.
Thank you,
Best regards,
Swapnil
