AI2 value
Defines AI dead band value in percentage where
100% = 10V in voltage mode and 100% = 20mA in
current mode. This is applicable for both AI1 and
AI2.
Note: 10% of the AI dead-band value is internally
added to the firmware as AI dead-band
hysteresis (positive and negative). This value
cannot be changed.
For more information on dead-band function and
its calculation, see section
page 70.
