The parameters should be inserted in the order
FCODE 26 thru 24 (number of decimals first) to
obtain the correct values.
Example:
A level controller is to regulate between 0.39 and 1.16 inches (10 and
30 mm). The sensor supplies 0 mA for 0 inches (0 mm), and 20 mA
fpr 1.97 inches (50 mm). Set FCODE 3 to 1, FCODE 1 to 0.0 and
FCODE 2 to 500.
Signal Range Selection
Use FCODE 119 thru 122 to select the appropriate electrical signal
range and linearization option for each of the four analog inputs, All
thru Al4. Select one of the options. To enable the square root option
for Al 1, use FCODE 107.
