Hey anyone,
I've been very occasionally working on restoring an older 2-group Brugnetti/Aurora machine I picked up that was in need of a serious overhaul. I've cleaned it all up and done a fair bit of work getting it back to a serviceable state, but I'm having a weird problem with the controller.
When I switch the machine on and it starts heating, I can use the buttons on the first of the two groups to get water coming out in nice measured doses. That's a win. However, the second group doesn't appear to work. The buttons light up, there's clicks from the Gicar controller box but no water.
Add to this, after a short period of time (maybe a minute) all the lights start flashing across both sets of buttons, and neither group responds to a button push. This is regardless of whether you've pushed buttons beforehand or not.
There seems to be quite a few jumpers and pins on the controller and I'm not sure they're in the right places. It also has a programming key that plugged onto two of the pins inside the box, and unfortunately I removed it during the restoration process and didn't note where it was connected. So now I have no idea. I assume that means the machine is in programming mode constantly, but having never used one of these machines/controllers I don't really know how that works.
So, I was wondering if anyone had:
1.) A manual or diagram for the Gicar PTC 890 explaining what these do. I can dream, right?
2.) A machine that uses this controller and is working. If so, I'd love to see where the jumpers are set both inside the box and on the side below where the button panels plug in.
3.) Any general advice. I'm a bit lost at this point.
This is the lid of the thing:
