6-62 Terminal X30/8 Max. Scale
Range: Function:
current signal 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:

6-63 Terminal X30/8 Bus Control
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the level of Output X30/8 if
controlled by bus.
6-64 Terminal X30/8 Output Timeout Preset
Range: Function:
0.00 %* [0.00 -
100.00 %]
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 will 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.

Option: Function:
Select the function of Terminal X45/1 as an
analog current output.
