”OUtL”
- this parameter determines the input value for which the output signal is
minimal
(depend of output mode „
Omod
”).
“OUtH”
- this parameter determines the input value for which the output signal is
maximal
(depend of output mode „
Omod
”).
The analogue output value is calculated due to formula given below:
Out
=
W
−
" OUtL"
"OUtH"
−
"OUtL"
×
B
−
A
A
where:
W
– displayed value,
Out
– analogue output value,
B
– higher range limit (20mA / 5V / 10V),
A
– lower range limit (0mA / 4mA / 0V / 1V / 2v),
“
OutL
” parameter can be greater than “
OutH
”. In this case the conversion
characteristic is reversed, it means that if input value raises the output value falls.
”
Lo r
”, ”
Hi r
”
- this parameters define the output value range. If calculated output value
Out
exceeds defined range then analogue output generates signal equal to upper
or lower border of the defined range. These parameters defines the percentage
extension of nominal analogue range (with 0,1% resolution).
Parameter “
Lo r
” defines lower border of the range due to formula:
Out
min
=
A
- (
A
× “
Lo r
” %), where:
A
– lower signal value range limit.
This parameter can be set from 0 to 99.9% (for active current output and active
voltage output) or from 0 to 29.9% (for passive current output).
Parameter
“Hi r”
defines higher border of the range due to formula:
Out
max
=
B
+ (
B
× “
Hi r
” %), where:
B
– higher signal value range limit.
