Function:
[0 - 200 %] Scale the maximum output of the
selected analog signal at terminal
X42/7. Set the value to the
maximum value of the voltage
signal output. Scale the output to
give a voltage lower than 10 V at
full scale; or 10 V at an output
below 100% of the maximum signal
value. If 10 V is the required output
current at a value between 0–100%
of the full-scale output, program
the percentage value in the
parameter, that is 50%=10 V. If a
voltage 0–10 V is required at
maximum output, calculate the
percentage as follows:
10V
desired maximum voltage
that is
10V
5V : × 100 % = 200 %
5V
See Illustration 3.31.
Function:
[0 - 100 %] Holds the level of terminal X42/7 if
controlled by bus.
Function:
[0 - 100 %] Holds the preset level of terminal
X42/7.
If a fieldbus and a timeout function
are selected in
parameter 26-50 Terminal X42/9
Output, the output presets to this
level.
Function:
Set the function of terminal X42/9.

Sensor 4
Function:
[0 - 200 %] Scale the minimum output of the
selected analog signal at terminal
X42/9 as a percentage of the
maximum signal level. For example,
if 0 V is required at 25% of the
maximum output value, program
25%. Scaling values up to 100% can
never be higher than the
corresponding setting in
parameter 26-52 Terminal X42/9 Max.
