Definition
C2 RANGE
4-20mA
0-20mA
SECOND CURRENT OUTPUT RANGE—Allows the
user to easily select 4-20mA output or 0-20mA
output operation without the need for recalibration of
the instrument.
ATTENTION Changing the Current Output Range
will result in the loss of Field Calibration values and
will restore Factory Calibration values.
LOW VAL
Low Scale Value within
the range of the selected
variable to represent the
minimum output (0 or 4
mA)
OUTPUT LOW SCALING FACTOR—This is a value
in engineering units used to represent all configured
parameters except Output.
For Output, this is a value in percent and can be any
value between –5 % and +105 %. However, keep in
mind that relay output types can only be scaled 0 %
to 100 %.
HIGH VAL
High Scale Value within
the range of the selected
variable to represent the
maximum output (20 mA)
OUTPUT HIGH SCALING FACTOR—This is a
value in engineering units used to represent all
configured parameters except Output.
For Output, this is a value in percent and can be any
value between –5 % and +105 %. However, keep in
mind that relay output types can only be scaled 0 %
to 100 %.
CUR OUT3
ATTENTION
Prompts for the Third
Current Output
Selection appear only
when the Third
Current Output option
is installed.
Same selections as for
CUR OUT2
THIRD CURRENT OUTPUT SELECTION—
Provides a milliamp output representing one of
several control parameters. The display for Third
Current Output viewing will be in engineering units
for all but output. Output will be displayed in percent.
ATTENTION Other prompts affected by these
selections: 4mA VAL and 20mA VAL.
ATTENTION When Loop 2 Output is configured for
CURRENT, the Third Current Output is forced to
“OUTPUT 2”.
ATTENTION CB OUT should not be used for Three
Position Step Control or Position Proportional
Control applications.
C3 RANGE
4-20mA
0-20mA
THIRD CURRENT OUTPUT RANGE—Allows the
user to easily select 4-20mA output or 0-20mA
output operation without the need for recalibration of
the instrument.
ATTENTION Changing the Current Output Range
will result in the loss of Field Calibration values and
will restore Factory Calibration values.
