Parameter Unit Description / Notes
 It selects the signal type of the current analog output AO2.
P255 0 to 1
AO2 Analog Output [ 0=0-20mA ]
Type (0 to 20)mA or -
(4 to 20)mA
P255 AO2 Output Type
0 (0 to 20)mA
1 (4 to 20)mA
 For transforming the current analog output AO2 to a voltage output
of 0 to 10V, connect a resistor of 500Ω ± 1% 0.5W in parallel with
the output signal.
 Remember when the output type is selected to (4 to 20)mA, this will
be the total range of the signal output.
0% of the signal = 4mA and 100% of the signal = 20mA.
