Plate Cleaner Vacuums Dead

Hey all. I'm running a QMDI 46 Plus.
This morning my plate vacuums seem completely dead, zero section. I burnt a job and it cycled through everything fine but the vacuums never kicked on. I checked after and error 15-07 was up, insufficient vacuum pressure.

When I try to run through a blanket wash it stops after about 3 seconds.

Otherwise the press is running fine, and the plate burn was ok.

I talked to my tech and he never heard of this before, does anyone have any ideas what to do?

 

Check if you have the vaccum on the each unit, the best switch it on with SF 71 and "+" and put your hand on the place where the filters are. You will feel if every unit get enough vaccum (the display is turning to H). Look for the reason if you find the unit where the vaccum is weaker, or doesn't exist.
Could be hose or the motor. If all work fine than it could be the one of the vaccum sensors. If on all four units no vaccum, than probably fuse has to be switched again.

I'll have to try that tomorrow. I did put a piece of paper over each of the 4 vacuum openings today and there was no suction on any of the 4 units.

 

Where is that fuse located?

Hey Jan, I tried SF 71, the only things there I could toggle was between "OFF" and "ON" (L appeared in the bottom, I was unable to get H) Nothing seemed to happen when I did this).

By 'switching the fuse' do you mean turning it off and on again, or replacing it? I tried flipping it on/off, no change. If a new fuse is needed is this something that an electrician/tech must do?

Thanks Jan (or anyone else)!

 

Yes, you need electrician to messure if you have Power Supply on your fuse and it is not switching through.
Could be that PS is OK but the singnal to switch high revolutions is not reaching Ametek blowers. In this case you would see the Ametek blower turning in stand by speed (slow).

Ok, thanks. I appreciate your help Jan.

 

Did you ever resolve this problem? I am having the same issues and have not found the solution. Any info would be great. Thanks....Mike

 

No, I didn't (yet). For now I'm running the press without the cleaners. The plates still burn ok, however it's kind of annoying because the blanket washers can't run.

 

Hi Impressed,
did you checked whether you have 220V power supply on your fuses?
Do the blowers turn with stand by speed?

It normaly,you cann't run blanket wascher on Plus and Pro without vaccum.

Hi Jan. No, I haven't looked into the fuse yet. Can any electrician do that or would I need a Heidelberg tech to do this?

And no, it seems the vacuums don't turn at all.

 

you could do it yourself with simply multimeter ,or voltmeter.

 

Fixed it. $5 dollar resistor on the 15X4 strip. It is a 470 ohm 5 watt wire wound resistor.

 

That's awesome Mike! Unfortunately I'm almost electrically useless. How did you pin point this issue? Did you just use a volt meter or just a lucky guess?

 

Hi Impressed, your problem is different. AGS has had broken 470ohm resistor. In such a case the Ameteks are runnig only one speed without possibility to switch over (it's high speed as I remember well).
In your case no movment is present, so it could be broken fuses or some other interuption of 230V power supply.

2 plate vacuum units not working (just got the press and do not know the history)

 

used the sf 3+7 71 function to turn on the vacuum. 1st and 4th vacuum inits worked but not the 2nd and 3rd. Is the sensor built in to the vacuum unit? How can I check the units? Can they be serviced or only replaced?

Thank you Dan
