Purpose: This module is used to configure input voltage characteristics (e.g., input voltage range), and
how the input signal is interpreted (linear or square root representation).
Analog Input
(Display Only)
ANI
H000
H001
0
This is the value in engineering units of the
measured input after all signal conditioning
has been applied.
Engineering
Span
SPAN
C256
C257
100
This determines the upper range the
analog input represents in engineering
units. The upper range value equals
Engineering Zero plus Engineering Span.
Engineering
Zero
ZERO
C276
C277
0
This is the lower range value.
Digital Filter
Index
DFILT
B269
B270
3
This controls a first order filter that is
applied to the input signal. The time
constant is entered as an index value as
follows:
0 - No Smoothing (no effect)
1 - 0.05 s
2 - 0.1 s
3 - 0.3 s
4 - 0.7 s
5 - 1.5 s
6 - 3.1 s
7 - 6.3 s
8 - 12.7 s
9 - 25.5 s
10 - 51.1 s
11 -102 s
12 - 205 s
13 - 410 s
14 - 819 s
15 - 1638 s
0 - 5 V Input
NOBIAS
L416
L417
0
Setting this parameter to 1 indicates the
input range is from 0 - 5 volts (0-20mA).
0 indicates the input range is from 1 - 5
volts (4-20 mA).
Square Root
Signal
SQRT
L440
L441
0
When a 0, it indicates the analog input
signal should be interpreted linearly.
When 1, it indicates the analog input signal
should be interpreted as a square root
representation of the value.
When square root is selected, input
signals less than 1% (10% input range)
force the input to its zero value.
Calibrate Zero
CIZ
B263
B264
This is the calibration zero adjustment.
This parameter is factory set and should
not need adjustment under normal
operation. See
for adjustment.
Calibrate Span
CIS
C296
C297
This is the calibration span adjustment.
This parameter is factory set and should
not need adjustment under normal
operation. See
for adjustment.
