Sab 128 Problems

[RANGER1]

The capasity is calibrated. The compressor goes on 100% and everything seems ok. Then suddenly the amps go down from 170 to 140 and suctiongas temperature also rises, apparatently for no reason. It seems to loose capasity and compression. But both the Unisab and the clock show 100 % capasity. It sometimes work, sometimes not.
Is it possible that the capasity is not calibrated when both the Unisab and the clock shows the same? The clock follows the slide mecanicaly, doesnt it?

Depending on what potentiometer you have it's a magnet on old type in picture supplied by Tycho.
New type is linear position indicator, also magnet.

Problem solved.
The guide for the slide that is pressed together with the slide was not good enough connected. Sometimes the factory use glue to hold this together. This glue had been broken so the slide was loose. But not too loose, because sometimes it was fastened, and sometimes not. That is why I had so big difficulties to find the fault. Now I will glue it properly and see what happens. Thanks for all your input and advises. Hopefully it will be a long time till my next problem.

Marthe,
Glad your problem is fixed.
Can you give a bit more detain on what you did to fix it, as I'm not sure if you have old type potentiometer or newer type LPI like in my link.
Anymore information appreciated.


Thanks

I have the old potetionmeter.
As I dismantled it again, I found that the slide was loose.

Marthe,
We go out of our way to try & help & would like to know exactly what you did to fix it so we can learn from it.
Your answer is to vague to make anything of it.
Do you have a picture, anything?
What is slide, is it slide valve, slide something else, your terminology i do not understand.
Maybe you mean potentiometer, or dial that turns it?
