Connect the controlled variable x1 (Pt 100, three-wire
circuit) to slot AE3. The measuring range is programmable.
The min. span is 50 K, the min. start-of-scale value is
- 50 °C, the max. full-scale value is 850 °C (see
instructions on page 76). Connect the disturbance variable
x2 to analog input AE1.
The controlled variable and disturbance variable can be
interchanged (S8 = 0, S10 = 0).
Feedback of final control element position via resistance
transmitter at AE4 (instruction on page 76).
The alarm circuit monitors the negative deviation xd for
max./min. deviations (set parameters A2 and A1 !).
Please refer to the remarks on page 108 and the note on page 15 !
Setting of configuring switches: S1 = 1, S2 = 2, S8 = 1, S9 = 1, S10 = -2, S32 = 1
