The selection of the desired function for each
analogue input is done by the configuration of the
dedicated parameter in the “ Parameters > Configure
I/O > analogue inputs” menu combined with the
correct setting of the Hardware configuration jumpers
on the 100N-MASTER3 under the removable front
cover (see the side image).
In particular, the configuration is as follows:
For NTC probes
: J*1=1-2, J*2=2-3, J*3=open
For 4-20mA probes : J*1=2-3, J*2=1-2, J*3=open
