x
The controlled variable x from the Pt 100 is applied to the
analog input AE3. The measuring range can be programmed;
the min. span is 50 K, the min. start-of-scale value - 50 °C, the
max. full-scale value 850 °C (see information on page 76).
The manipulated variable output is 0 to 20 mA; a signal range
of 4 to 20 mA can be set using configuring switch S37 = 1.
The alarm circuit monitors the controlled variable
(temperature) (set parameters A2 = min. and A1 = max.).
PIease refer to the remarks on page 108 !
Setting of configuring switches: S8= 1, S22 = 1
