Philips pdt 024 schematics

Hi all,

i've recently bought a Meopta Opemus 5 enlarger that came with a non working Philips Pdt 024 timer/dosimeter.

I've read the manual and how it should work, knobs light goes on, but if i set the dosimeter mode on, no electricity goes to the connected enlarger (its switch is on).
If i set the switch on the sun symbol, with factor 1, set the time and press activation, nothing happens either.

I showed it to a guy repairer i know but he told me he may need the schematics to solve this.

Can anybody help me on this?

Thank you all

Get a new timer.

I agree, for such a plain meter/timer it rather is not worth the hassle.

It is unlikely you find a circuit diagram I assume, but nevertheless if you want to go into it, a experienced electronics person may find the fault nevertheless.
