Setpoint and
parameter set
switching
A binary function can be used to switch between setpoint 1 and setpoint 2 or
parameter set 1 and parameter set 2.
In order to switch between the four possible setpoints, two binary functions must be
configured to “setpoint switching”. The states of the two binary functions are
designated Z1 and Z2 and switch the setpoints over as shown in the table below:
0 = contact open /OFF 1 = contact closed /ON

Level inhibit:
The parameter and configuration levels are inhibited.
Program end signal:
The signal is active after approx. 1 second (pulse)
Text display:
If the binary function is active, a configurable text is shown in
the lower display. The text can be uniquely defined (only
through the setup program).
Type 703041:
The settings for the binary inputs 1+2 have priority over those
for the logic outputs.
