Vesuvius Pressure Profiling Machine - General Discussion

Adrianmsmith You think this is normal behavior?

At 13 bar that would be expected (normal), the vent valve on E61 machines starts to let by at about 12-13 bar.

DavecUK Thanks Dave!

Thinking about it the expansion valve is probably opening as well.

Spid3r00 Yup, I’ve monitored mine at around the same. I became interested when it blew the 10 amp fuse in the mains plug of the power cable I was using. It needs a 13 amp fuse and a cable, IEC plug and socket accordingly rated.

Spid3r00 oh ok that’s a lot :).

You can easily half the current draw if you wish by setting boilers to heat consecutively rather than concurrently - it’s hidden in the menu somewhere.

Spid3r00 Advanced Menu (the one where you can adjust PID settings, etc.)- Sequent. Heating. If set to enabled boilers will heat sequentially. :-)

Spid3r00 For now I did install power cord directly

DavecUK Absolutely no problem doing this and connecting directly, as the plug has a fuse in it.

I think I see one serious safety issue. Not entirely clear but it appears that the ground wire from the mains lead is trimmed shorter than the live and neutral. It also looks like it isn’t secured with a Wago and is just stuffed up the spade connector.

If that’s the case, if the lead gets pulled a little bit, the ground could come loose, but live and neutral stay connected. There is the potential for the machine to be operating with no safety ground.

When hard wiring best practice is to leave the ground wire the longest - so if the cable gets tugged it is the last to be dislodged.

Gagaryn The ground wire is secure well, I can tell you that :)

It really isn’t - it’s bodged. It’s a real safety risk for anyone that comes into contact with your machine.

The risk is aggravated by your bypassing of the fuse in the power inlet and by the unavoidable proximity of water to the power fixture which means there is a likelihood, no matter how small you think that likelihood is, of that power inlet getting wet.

I already explained that as you have left it, if that power cable - also bodged through the base of the machine with no proper anchor - just a zip tie, gets pulled - the first cable to fail will be the earth cable so there is the potential for the steel case of the machine to become live.

It would take two minutes to make safe, don’t let a bruised ego stop you from doing that.

Gagaryn I really don’t trying to argue what is safe and what is not… I mean ground wire i secure hard and it doesn’t move freely, now is compared to installation ACS did originally from factory. Now I have fuse in power inlet (11A from Eve Energy) and installation in my apartment have also fuse of course. I will dough install the fuse in my machine next week.

@DavecUK any news regarding overshooting the pressure on Vesuvius? What can we hope it will happen to solve issue?

Spid3r00 any news regarding overshooting the pressure on Vesuvius? What can we hope it will happen to solve

I have nothing, I’m out of ideas?

DavecUK difficult to be believe that is even possible 😄… does @Paolo_Cortese have any ideas how to solve this?

I’m waiting a reply overall i need to know if book the flight or not… everyway a solution must be found!!!
