Functional Principle:
The operating mode switching function can send up to 4 different operating modes when a button is
pressed shortly. The operating modes are switched over one after the other. Depending on the set
parameters, for example, when the key is pressed, the 2nd changeover value is transmitted if the 1st
changeover value was previously transmitted and the 3rd changeover value if the 2nd changeover
value was previously transmitted.
Push button long:
In addition to the switchover by a short keystroke, a fixed operating mode can be transmitted by a
long keystroke.
One of the 4 operating modes can be transmitted permanently. Thus, a long keystroke would always
transmit a fixed operating mode (independent of the last changeover value).
Switching type:
Limit stop
: With the limit stop switch mode, the 4th operating mode is transmitted again after the
4th operating mode has been sent.
Overrun
: With the overflow switchover mode, the 1st operating mode is sent again after the 4th
operating mode has been sent.
For the single button function, this parameter is permanently set to
“
Overrun
”
.
Presentation:

Each operating mode is assigned a fixed symbol. The colour of the symbol can be set as required for
each operation mode:
