- - - - C C C C r r r r L L L L Minimum value on input AIC, adjustable from 0 to 20 mA
- - - - C C C C r r r r H H H H Maximum value on input AIC, adjustable from 0 to 20 mA
These two parameters are used to configure the input for 0-20 mA, 4-20 mA, 20-4 mA, etc.

CrL
If the input used is AI2, these parameters remain proportionally active :
4 mA v 2 V
20 mA v 10 V
For a 0 - 10 V input, configure CrL at 0 and CrH at 20.
These parameters should be adjusted when the PI function is activated.
