- this parameters define the output value range. If calculated output value
Out
exceeds defined range then analogue output generates signal equal to the
upper or lower limit 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).
In example on page
of the
DISPLAY VALUES CALCULATION
paragraph
the procedure of the analogue outputs determining is presented in details.
“
AL
”
- this parameter determines the behaviour of analogue output if any critical situation
occurs. According to version of the device, this parameter can be set:
For active current output:
“noCH”
- current will not change,
“22.1”
- current will be set to 22.1 mA,
“3.4”
- current will be set to 3.4 mA,
“0.0”
- current will be set to 0 mA.
For passive current output:
“noCH”
- current will not change,
“22.1”
- current will be set to 22.1 mA,
“3.4”
- current will be set to 3.4 mA,
For active voltage output:
“noCH”
- voltage will not change,
“11.0”
- voltage will be set to 11 V,
“5.5”
- voltage will be set to 5.5 V,
“1.2”
- voltage will be set to 1.2 V.
“0.6”
- voltage will be set to 0.6 V,
“0.0”
- voltage will be set to 0 V.
When the critical situation goes, the output signal will be set to value calculated due to
formulas given above.
