E-Aux Analog 0-1VDC and 0-5VDC and 4-20 mA input type
Menus → System → Configure E-Aux →E-Aux 1-8→Input Type→0-1V
→0-5V
→4/20mA
Use an analog input when monitoring an external device to control/alarm a device
with a signal type that is 0-1VDC, 0-5VDC or 4-20mA. An example - monitoring
a total dissolved gas pressure sensor whose signatl is a 0-5VDC.
Notes:
-
It is normal to hear an on-board relay “click” when switching to or from the
4/20ma E-aux input type.
-
Analog systems will not monitor, control, or alarm properly if a device that
operates outside the configured analog range is installed and configured.
Suffix
Menus → System → Configure E-Aux →E-Aux 1-8→Suffix
Enter the Suffix (up to 4 characters) to describe the input type or units. The suffix is
displayed at the Run Screen and throughout E-Aux menus. The suffix is typically
used to describe the input signal type.
Example - when using a total dissolved gas pressure sensor, “mmHg” could be used
as a suffix for measuring TGP (total dissolved gas pressure), as shown for an aux
analog input - figure 4.6, page 106.
Min and Max values
Menus → System → Configure E-Aux →E-Aux 1-8
→Min
→Max
Min and Max values are user defined. The range is -10000 to 10000. Min and Max
values are used for scaling the input value received from an analog aux input. The
min and max values may be configured to correspond to the minimum input level
(i.e. 0VDC or 4mA) and maximum input level (i.e. 1VDC, 5VDC, or 20mA). The
Min value must be less than Max value.
Configuring the 5200A
Example - when using a total dissolved gas pressure sensor (0-5VDC input type)
enter -400 for min value. The 5400 will display “-400” when the input value is 0VDC.
Set the max value to correspond to the maximum input value as +400. The 5200A
will display “400” when input value is 5VDC.
Notes:
-
The 5200A will monitor and data log based on the “min” and “max” voltage
or current signal.
-
To enter negative values, type the whole number then select “-” on the nu-
meric keypad.
-
Whenever min and/or max values are changed, go to
Menus → System →
Sensor Setup → Aux 1-2 → Control Low and Control High
menu to verify
control/alarm values are correct for the application.
Input Scale Min and Max values
Menus → System → Configure E-Aux →E-Aux 1-8
→Input Scale Min
→Input Scale Max
Input scaling allows a way to view data within a specific input range of the input type
(0-1v, 0-5v, 420/ma) in greater resolution. In the below example 0-1v is the input
type and display format = 0. The configured Min value is 0, and the configured Max
value is 1000. The input scale Min is .25 and the input scale Max is .75. (The user
wants to only view data within this specific range). In the below example an input
value of .25v = a display and datalog value of 0. An input value of .50v = a display
value and datalog value of 1000.
