Hello!
I am looking for a solution how to deal with such problem: SattCon 125 controller stopped with "parameter error" on the display, probably because of the low battery (the battery now is replaced). And I cannot find any manuals for this kind of PLC. How to start the controller? A great thanks in advance!

 

This place sells tested, used equipment. They don't mention selling manuals, but who knows?
They do mention having to use computer equipment from the 1980's for their testing.

You might contact them to see if they have documentation for sale.
