Wiring diagram versions

Each coffee machine has its own set of wiring diagrams.
Wiring diagrams which contain "ULKA" as reference in the headline show the
wiring for the coffee pump made by ULKA/CEME while the other wiring diagrams
show the wiring for the SYSKO coffee pump.
Depending on series and manufacturer, the coffee pump is equipped with a different
thermal protection device (see "Replacing coffee pump and flow meter" on page 55):
- either a thermo fuse (STB)
- or a reversible temperature switch (Limitor)
The type of thermal protection device used for the coffee pump is shown in the corre-
sponding wiring diagram version.
