Why is my Leakshield showing state as "Unprotected?"

This is what it's been doing this afternoon. Why would the setpoint be changing so often even though the pressure does not change and the pump doesn't run? Is this because my D5 is changing speeds?

The problem may be that your minimum vacuum is not sufficient to compensate for the pressure of your pump.

According to your picture, the pump is at 360 mbar and your minimum vacuum is 350 mbar, in which case water would leak out if there is a leak and consequently your system is unprotected.

Since the pump speed has only marginal influence on the cooling, you can simply set the pump to a fixed value at which you have enough flow and the pump sounds most comfortable to you.

If you then set the minimum value of the LEAKSHIELD accordingly above the pump pressure, the problem is solved.

It seems like simply finishing a render and then loading up a game is enough to trigger the leak warning. How do I manage this?

This is the log from when the warning popped up. The machine was running under steady-state load until 20:46, at which point the coolant temp dropped quite quickly. I have already configured the pump to run at a constant rpm, so that did not change when the coolant temp & system load changed. I also don't understand why there is a big string of "Pressure setpoint changed" entries.

I have also included two screen caps from the different info pages in Aquasuite. Note that the high pump usage on 20:Jul and 21:Jul was when I was trying to adjust settings and is not representative of an actual leak.

Any help with this would be great. At this point, I cannot use the LEAKSHIELD to shield my machine from leaks. I have been forced to disable all alarms.

I have now manually changed the vacuum settings from the ones that the setup wizard selected. Perhaps this will help. The new settings are:
  • Maximum Negative Pressure: 475 mbar
  • Set Point Negative Pressure: 435 mbar
  • Minimum Negative Pressure: 400 mbar
  • Use Adaptive Pressure Preset: No
