5.4.6 Set UNI-module CAE3
The CAE3 menu is only offered in the selection mode if the structure switch S6 is set = 4 to 7
(input signal for AI3 is generated by the UNI-module)
With this menu the measuring range can be determined for the various signal transmitters
(selection with S8 and S9) and fine adjustment can be made.
S6 Input signal AI3 (slot 1) and transmitter fault message
[0] 0...20 mA or U,R,P,T without MUF
1 0...20 mA or U,R,P,T with MUF
2 4...20 mA or U without MUF
3 4...20 mA or U with MUF
4 UNI module Min at sensor break without MUF
5 UNI module Max at sensor break without MUF
6 UNI module Min at sensor break with MUF
7 UNI module Max at sensor break with MUF
S8 Input signal AI3 (slot 1) with UNI--module (only active at S6=4/5/6/7)
[0] mV (linear), with measuring range plug U or I
1 Thermocouple with internal reference point
