Function:
Scale minimum output of selected analog signal at terminal 42 as percentage of maximum signal value. E.g. if 0
mA (or 0 Hz) is desired at 25% of maximum output value, programme 25%. Scaling values up to 100% can
never be higher than corresponding setting in par. 6-52.
Function:
Scale maximum output of selected 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 per-
centage 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:
m A
