Durst Stades 1800 controller

[ponchoman]

Hi,

I'm trying to repair the Durst Stades 1800 controller for moving the table and head of a Durst CLS 1840.

One of the relays is not responding and the head won't go down. It's a b*tch to do without the schematics so before I start drawing out the board, does anyone have experience with this, schematics, etc...

Durst and the manufacturer of the relay have no more specs or info apparently...

Thanks

Anyone has some info?

Can you show a picture? I'm not familiar with the "Stades 1800" but maybe it shares components with the Larano 1840 for which I have schematics.

This is the enlarger

This is the controller!

THis is the pcb with the defective relay!

Cleaning relay contacts is a pretty common thing keeping vintage HiFi gear running when the speaker protection circuit uses a relay. Do you know what is wrong with the relay? Relays are not that hard to source if you know the voltage and the switching configuration.

That is not the best picture because it mostly shows the CLS1840 head which was common to about five different enlargers.

Hello, I meet the same problem with my Stades, couple of relays don't work.
Did you solved the problem ? If so what you did?
Thanks Francesco
