User manual - WEIGHT METER SWI-94
For active voltage output:
”
oFF
”
- voltage output disabled
,
”
0-5
”
- voltage output enabled with 0 ÷ 5V mode
,
”
1-5
”
- voltage output enabled with 1 ÷ 5V mode
,
”
0-10
”
- voltage output enabled with 0 ÷ 10V mode
,
“
2-10
”
- voltage output enabled with 2 ÷ 10 V mode,
”
modb
”
- voltage output controlled via RS-485 interface.
“SourCE”
- this parameter defines source of signal controlling the analog output,
and can be set to one of two values:
“GroSS”
- output is controlled due to gross value of weight,
“ nEtt ”
- output is controlled due to nett value of weight.
”OUt LO”
- this parameter determines the input value for which the output signal is
minimal
(depend of output mode „
OUtmod
”).
“OUt HI”
- this parameter determines the input value for which the output signal is
maximal
(depend of output mode „
OUtmod
”).
The analogue output value is calculated due to formula given below:
Out
=
W
−
" OUt LO"
"OUt HI"
−
"OUt LO"
×
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),
“
Out LO
” parameter can be greater than “
Out HI
”. 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.
This parameter can be set from 0 to 19.9% (for active and passive current
output) or from 0 to 9.9% (for active voltage output).
