Furthermore, the Teach procedure can also be automated – the automatic Teach functions (Autotune func-
tions) programmed for this purpose are described in detail in the following chapters.
The 5 different automatic Teach functions (Autotune) are pre-programmed for various process valve types
(e.g. single-acting or double-acting actuators, double-seat valves, etc.) and for various starting positions of
the process valves (open, closed) - the automatic Teach function (Autotune) being used must be selected
according to the process valve type and application.
The
colour coding/colour assignment for the individual valve positions/positions are described in
chapter “21.1.1 Device specific LED mode “8681 Classic Mode”” .
The valve positions/positions (S1 to S4) as well as various errors and warnings are distinguished by various
“flashing patterns” – see chapter “21.2 Flashing pattern & fault signalling” .
