Example 3: Scaling with Current/Voltage Transducer (Process) Input.
The following example include details for a specific scenario in
which a 4 - 20 mA input is to be represented as a measurement
of 0 - 100 percent.
Press
d
41) Press
d
at the
IN.RD
prompt. Display shows
IN!1
Input 1
Submenu.
Press
d
42) Display shows Input 1 value with 1
st
digit flashing.
Press
b
&
c
43) Use
b
and
c
buttons to enter
IN!1
value.
The
IN!1
value = min. input value x conversion number
from Table 3.1
Enter 4 mA as 4 (mA) x 500 = 2000
Press
d
44) Display advances to
RD!1
Reading 1 Submenu.
Press
b
&
c
45) Use
b
and
c
buttons to enter
RD!1
value.
This value corresponds to Input 1 in terms of some meaningful
engineering units. To show 4 mA as zero percent enter
RD!1
value = 0000.
Press
d
46) Display
IN!2
Input 2 Submenu.
Press
d
47) Display shows
IN!2
Input 2 value
with 1
st
digit flashing
.
The
IN!2
value = max. input value x conversion number
from Table 3.1
Enter 20 mA as 20 (mA) x 500 = 10000 (entered as 9999)
Press
b
&
c
48)
Use
b
and
c
buttons to enter
IN!2
value.
Press
d
49) Display advances to
RD!2
Reading 2 Submenu.
Press
b
&
c
50) Use
b
and
c
buttons to enter
RD!2
value.
To show 20 mA as 100 percent enter
RD!2
value = 0100
Press
d
51) Display flashes
STRD
stored message momentarily and
then advances to
ALR1
only, if a change was made, otherwise
advances to
ALR1
Alarm 1 Menu.
