Parameter Descriptions
6-62 Terminal X30/8 Max. Scale
Range: Function:
output. Scale the output to give a lower current
than 20 mA at full scale or 20 mA at an output
below 100% of the maximum signal value. If 20
mA is the desired output current at a value
between 0 - 100% of the ful-scale output, program
the 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 the
percentage value as follows:
20 mA / desired maximum current x 100 %
20 − 4
i . e . 10 mA : x 100 = 160 %

6-63 Terminal X30/8 Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of Output X30/8 if controlled
*
by bus.
6-64 Terminal X30/8 Output Timeout Preset
Range: Function:
0 % [0 - 100 Holds the preset level of Output X30/8.
*
%] In case of a bus timeout and a timeout function
is selected in 6-60 Terminal X30/8 Output, the
output is preset to this level.
3.8.8 6-7* Analog Output 3 MCB 113
Parameters for configuring the scaling and limits for
analog output 3, Terminal X45/1 and X45/2. Analog
outputs are current outputs: 0/4–20 mA. Resolution on
analog output is 11 bit.
6-70 Terminal X45/1 Output
Option: Function:
Select the function of Terminal X45/1 as an
analog current output.
[0] No When no signal on the analog output.
