Range: Function:
100.00% * Scale maximum output of selected
[0.00-200.00%] analog signal at terminal 42. Set value
to maximum value of current signal
output. Scale output to give a current
lower than 20 mA at full scale; or 20
mA at an output below 100% of
maximum signal value.
If 20 mA is the desired output current
at a value between 0-100% of the full-
scale output, programme percentage
value in the parameter, i.e. 50% = 20
mA. If a current between 4 and 20
mA is desired at maximum output
(100%), calculate percentage value as
follows:

i.e.

10 mA = × 100 = 200 %
