Wiring
Decide during planning which function is to be connected and
where this will be.
1. Connect inputs and outputs
Here are the tables for the example:
Mounting and wiring - continued
The function of the switch functions can be seen in the last column.
There are pressure transmitters AKS 32R and AKS 2050 available for
several pressure ranges.
Here there are three different ones. One up to 12 bar, 34 bar and 59 bar.

Remember the isolation amplifier
If signals are received from different controls, e.g. heat re-
covery for one of the inputs, a galvanically insulated module
should be inserted.
