6-71 Terminal X45/1 Output Min Scale

Range:

Function:

0.00%

[0.00 -
200.00%]

Scale the minimum output of the selected
analog signal at terminal X45/1, as a
percentage of the maximum signal value.
E.g. if 0 mA (or 0 Hz) is desired at 25% of
the maximum output value, then
programme 25%. Scaling values up to
100% can never be higher than the
corresponding setting in

6-72 Terminal

X45/1 Max. Scale

6-72 Terminal X45/1 Output Max Scale

Range:

Function:

100%

[0.00 -
200.00%]

Scale the maximum output of the selected
analog signal at terminal X45/1. Set the value
to the maximum value of the current signal
output. Scale the output to give a current
lower 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
full-scale output, programme 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 (example where
desired max. output is 10 mA):

6-73 Terminal X45/1 Output Bus Control

Range:

Function:

0.00%

[0.00 - 100.00%] Holds the level of Analog Output 3

(terminal X45/1) if controlled by bus.

6-74 Terminal X45/1 Output Timeout Preset

Range:

Function:

0.00%

[0.00 -
100.00%]

Holds the preset level of Analog Output
3 (terminal X45/1).
In case of a bus timeout and a timeout
function is selected in

6-70 Terminal

X45/1 Output

the output will preset to

this level.

3.8.9 6-8* Analog Output 4 MCB 113

Parameters for configuring the scaling and limits for
analog output 4. Terminal X45/3 and X45/4. Analog
outputs are current outputs: 0/4 – 20 mA. Resolution on
analog output is 11 bit.
