Description:
1) Program one analog output (AO) to look at armature voltage.
2) Wire the AO programmed for armature voltage to an analog input (AI). Since the analog inputs can only accept voltage, a 500 ohm resistor will have to be placed in parallel, which will convert the 0-20 mA signal to 0-10 vdc. a. To calculate the minimum and maximum voltage values for the AI, divide the low and high value of the scaled range by 240. Then, multiply this value by 10 (the maximum AI voltage) b. 30 / 240 = .125 X 10 = 1.25 vdc or 125 mvdc i. Set 13.22 to 125 mvdc c. 191 / 240 = .796 X 10 = 7.96 vdc or 796 mvdc i. Set 13.21 to 796 mvdc
