The parameter and configuration levels are inhibited.
In addition, the start of autotuning is inhibited
Program end signal
PrES
Program end signal:
The signal is active after approx. 1 second (pulse)
Text display:
If the binary functions are active, a configurable text is
shown in the lower display. The text can be uniquely
defined (only through the setup program)
NOTE: Factory settings shown with BOLD text
Set point and
parameter set
switching
A binary function can be used to switch between set point 1 and set point 2 or parameter set
1 and parameter set 2.

In order to switch between the four possible set points, two binary functions must be
configured to set point switching. The stats of the two binary functions are designated Z1 ab
z” and switch the set points over as shown in the table below.
