• Every time I shut down the PC, I get a leak alert. It's like it's not understanding that the d5 next pump has shut down
  
• It'll throw an alert when the d5 next pump goes to a much lower power level.
  
• Leak test is not holding negative pressure about 400, while at 375 it looks almost stable
  
• When establishing pressure during shield setup, it'd stop and throw an alert that the pump was triggering too often, so it must be a leak... but the pump was triggering often because it had to do a fill up test and then establish operational negative pressure, picture below. I can fix that by manually lowering minium negative pressure to something lower than the current negative pressure

I'm curious how this goes for you. Hopefully, it is as simple as just leaving more air space inside of the reservoir.

I have entirely stopped using my LEAKSHIELD because of its false alarms. It seems like a flawed execution of a good concept.

The first thing I notice is that you have practically no air in the reservoir, but the LEAKSHIELD needs air to work properly, the less air volume there is, the more sensitive it reacts to pressure changes.

Have you calibrated the virtual flow sensor of the D5 NEXT and given the LEAKSHIELD as a flow sensor?

Is the system completely vented?

If the LEAKSHIELD is not holding pressure I would suspect that there is an air leak somewhere, does air visibly collect somewhere in the system when you have turned off the computer overnight and the LEAKSHIELD is in shield mode?

• I have increased the air volume to like 30%+ (leakshiled shows 92% filled, but that's wrong)
• I have calibrated the virtual flow meter
• the system is completely vented
• Just take a look at those leak tests screenshots. It's a very small air leak over 2000-3000 seconds. At 375 is almost stable. I was hoping someone could tell me if that's normal. I've found many mentions in this forum that a small pressure leak is expected because of e.g. temperature, pump speed, no system is 100% airtight
• Air doesn't visibly collect anywhere after overnight with the shield on

If I interpret this correctly you regulate your pump, why?

Zitat

Then it would be quite helpful if you would post the configuration of the LEAKSHIELD, without that it is also hard to say anything.

Zitat

Then also a picture of the status page would be very interesting.

You do realize that the LEAKSHIELD has very little headroom with these settings?

At 100% pump speed and 375 mbar pressure from the pump, the LEAKSHIELD inevitably reacts very quickly, since the system can only be protected with an overpressure above 375 mbar.

Since the flow rate values do not help you, I would rather go to a value around 100 l/h, then the pump generates a much lower pressure and the LEAKSHIELD has more headroom.

With the status page I meant the one in the Aquasuite under LEAKSHIELD.

Zitat von »Taubenhaucher«

You don't understand me, the pump generates a pressure of 375 mbar, as soon as the vacuum drops below this value your system is not protected, I can't say exactly how much vacuum is necessary, but if you are only protected up to let's say 385 or 390 mbar vacuum there is not much left.

With these settings, the LEAKSHIELD makes little sense and will certainly give you no pleasure.
