There does not seem to be a manual on the Siemens site.    What kind of manual came with it?   Have the Germans given up on documentation?

All the information is contained  in the S7-200 Smart System manual.

Possible faults are = loss of 24V DC, Overflow or undeflow ??

But checkout the manual sections C & D for diagnostic information.
