have no clue with electricity stuff.
thanx for any help....
I had undertaken literally hundreds of major electrical projects over the last 40 years before I got my broken Durst. In fact I got a soldering iron for Christmas when I was seven years old. Gary Mulder is also quite well versed in electronics.
If you have 'no clue' with electricity it might be best to find someone that can look at if for you.

Thanks a lot already!

Mains/line voltage electricity is not something to treat lightly. If you do not have a clue with electrical stuff, as ic-racer said, I highly recommend that you find someone else who does. Dealing with mains/line voltage is potentially fatal if you make a mistake. I have seen some "repairs" that were done so poorly that someone could easily be seriously injured or a fire started.
hello guys,
I just got a Durst 1840 and power supply EST 1000N , it was ok some time ago but there is a problem now
When I put it on "on" and start a timer to expose paper, the "shutter" on the head opens and closes non stop...
I think it could be a relay flickering...
-I tried several timers, same result
-tried different current socket in the building, no change
-electronic on the enlarger itself seems pretty simple so it could be on the power supply.
-the fan starts but seems to have some difficulties and acts as a stepping motor 'kind of"
-light is ok
excuse me if I'm not very precise, I'm french, I hope you understand the problem
any clue/advice?
Check the shutter motor board.
thank you IC-racer!
I do it this morning
Update:
It was a micro switch on the back of the board which didn't go back to its initial state!!
Thank you!!
HI, if you have plan, can you send me a copy please ?Quote:

Hello,
help me too with a copy of schematics for DURST EST 1000. The lamp does not light up!
Thanks
macmicus@gmail.com
When the EST1000N stabilizer is turned on, the scale backlight on the color head CLS1000 is working. When the timer starts, the shutter is released, but the 120v / 1000W lamp does not light up and the fan does not start.
The lamp is new, serviceable. All fuses on the stabilizer and CLS1000 are intact. A friend promised to help, but he needed a scheme of this stabilizer.
This scheme has been posted in the thread
https://www.largeformatphotography.i...ipment-problem
but it is of very poor quality.

Does anyone have a higher quality scan of this scheme? Work breaks due to breakdown)))
Hi,
I also have a problem with my 1840 Durst and the EST 1000N transmitter. When the enlarger is turned on the lamp lights up but only with very dim light. It worked properly for some time but then one time I tried this was the case. The enlarger is obviously very old. Any idea where the problem might be?
Cheer, Katri
And my email is lassila.katri@gmail.com if anyone have any idea how to proceed :)

Hi,
I would also be grateful, if a schema could be emailed to me by any user that has got it and would be so helpful to send it.
My email is form@rafsagan.net
Best regards,

I'm trying to repair a Durst EST 1000N power supply. Is there anyway you can send me the Durst EST1000N Schematic? I would really appreciate it. Thanks! Jay Overmoen
Can i ask you to send schematic me too :) Thank you! polllimer@yandex.ruQuote:

Sounds like bad caps. See if you can get the values off the schematic and replace your caps. Most power supply issues stem from the electrolytics going bad. Sometimes, they'll even look bloated or leaky. Can't hurt to replace them, even if they're still good.Quote:

My EST 1000 is now working! The electronics engineer repaired it. He replaced the capacitors С6, с12, с31, с52, с60, с61.
Wonderful, if he wants to fix other units, I'm sure there will be plenty of takers. LQuote:

Hi Everybody,
Like other people ,
I'm looking for a good quality copy of durst power supply EST 1000N schematics , cause mine has few hours on the clock , and some components has heated (too much ) and consequently i can't read specs on them (especially zener diodes )...
I would really appreciate that ...cause I'm stuck !
Thanks a lot for your help !
Regards,
Nick
Good evening !
I'm also looking for the schematics of the EST 1000N !
If someone have it, could he sent it by mail to me ?
Thank you !
I also need schematics please!
Actually, can't this be uploaded somewhere so those who have it won't need to send in email every time someone asks for it..? :)
Thanks in advance whoever will be kind enough to share it with me! :)

Apologies in advance if it's me not finding it but it seems the link you shared is just a discussion about collecting these files in the future..?
If that's the case - and whilst this is fabulous of course - can you help me out in the meantime with the EST1000N schematic please?
Thanks and regards,
Zsolt
I got a couple of email requests for that recently. People's email and user names almost never match, so I wasn't sure if I sent it to you already. PM me with you email and I'll send it.
why not post it here so it can be downloaded by anyone in need?

See the thread in post #30 above. I guess I could have started a similar thread on this forum.
ah too bad! at least you tried. thanks.
Forums change with time, so I thought maybe it might work this time. For example APUG did not allow direct image upload, but after becoming PhotoTrio, you can upload images.Quote:

Hi everyone, I'm also servicing a faulty EST1000N (The ecu switches on but not off and it does not seem it's a relay problem). I can see the switching operates with 2 thyristors and some logic ICs: it would be much easier to work with the schematic.
Does someone here still have it ?
Thanks and nice day.
check your pm
I have rebuild mine with a arduino, some relay's and a PWM module.
Some pictures.
The biggest problem is starting the cold lamp. If it’s cold it is almost a sort circuit.
Hi, I have a Durst EST 1000n that doesn't work.
Can I have a copy of the electrical circuit?

Thank you.
