Notes:
- Suffix, Min, Max, Input Scale Min, Input Scale Max and Display Format
are not available for digital inputs.
- In the 5200A sensor log, aux digital “closed” is logged as Aux 0.00. Aux
digital “open” is logged as Aux 1.00.
1. Wire aux digital devices - page 49.
2. Enter Aux menu
Menus → System → Configure Aux →Aux 1-2
3. Use
▲
and
▼
to scroll and highlight submenus.
4. Press

to select.
5. Configure digital input type and name.
6. Press
to save configuration and return to Run Screen.
7. Go to Sensor Setup Menus → Sensor Setup Aux 1-2 - page 142 to enable
and configure control/alarm on condition, control/alarm relay, and hold
off time.
8. Press to save configuration.
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 105.
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.
- 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.
