I tried this right now. Sometimes it stays but just for a short while where sometimes it just goes off immediately after failsafe is triggered.

I've also did some data logging right now with DFS, the timing pull is terrible. It indicates that there's no WM flow at all even thought the gauge shows flow.

Have you reinstated the FDC jumper back to PRK? The gauge cannot show flow if there is no flow.

Let me know.

Yes, it's back in PRK.

Yea. But then as I said, the data from the logs indicates no flow at all. And the pump still stops after the FS triggers.

Thanks for clarifying this "the pump stop after the failsafe is triggered.

OK, can you disable the failsafe by linking "DFS" with the "PRK" jumper. Let me know if the pump stop this time.

IF you mean having jumpers on DFS+PRK then ice already done that. The pumps stops as well.

This is very puzzling for me.

OK, let's do the next test, it will be a visual one.

Place the opened controller in line of view, tell me if the amber led continues to illuminate after triggering. I like to know if triggered is interrupted and stops the pump.

I did some runs just now and results are as follows:
- Pump starts then stops but flow is still carying on. I double checked that there's no flow with my data logging as I keep getting very big negative numbers of timing pull.
- Pump primes then go quiet. After the FS is triggered, the Amber LED goes off immediately or right after triggering by approx a sec.

All times are GMT +1. The time now is 03:12 PM.
