AE2 of the controller. The transmitter is powered via the
same lines. The input signal range of the controller is 4
to 20 mA.
Feedback of final control element position via resistance
transmitter to AE4.
The alarm circuit monitors the negative deviation xd for
max. / min. deviations (set parameters A2 and A1 !).
