Analog 0-1VDC and 0-5VDC and 4-20 mA
Menus → System → Configure Aux →Aux 1-2→Input Type
→0-1V
→0-5V
→4/20mA
Select the analog input type based on the signal being sent from the device.
Notes:
It is normal to hear an on-board relay “click” when switching to or from
-
the 4-20mA 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 con-
figured.
Suffix
Menus → System → Configure Aux →Aux 1-2→Suffix
Enter the Suffix (up to 4 characters) to describe the input type or units. The suffix
is displayed at the Run Screen. 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) - figure 4.6, page 101.
Min and Max values
Menus → System → Configure Aux →Aux 1-2
→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.
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”
-
volt-
age or current signal.
To enter negative values, type the whole number then select “-” on the
-
numeric keypad.
Configuring the 5200A
Whenever min and/or max values are changed, go to
-
Menus → System
→ Sensor Setup → Aux 1-6 → Control Low and Control High menu to
verify control/alarm values are correct for the application.
Display Format
Menus → System → Configure Aux →Aux 1-2→Display Format
Configure the Display format (0, 0.0, or 0.00) based on the resolution to be displayed
on the Run Screen.
Example - when using a total dissolved gas pressure sensor configure, the display
format as 0.0 - figure 4.6, on this page.
In the below screen shot, the Run Screen is displaying aux name “TGP,” suffix
“mmHg,” with display format “0.0”. The display value represents an input of 1.875
volts with 0-5VDC analog aux configuration. The min value = “-400”. The max
value = “+400”. The control/alarm low value is “-50”. Alarms are enabled for this
aux input.
figure 4.6
Notes:
Values are displayed based on the display format resolution. Example - if
-
the display format is 0.0 and the min value configured is 1.88, then 1.9
will be the value displayed in the min value menu.
5200A aux sensor logs record 0.00 resolution regardless of the selected
-
resolution in the aux analog display format configuration.
