Configuring 4-20 mA Inputs
The Analog Input setup screen is used
to configure the 4-20 mA analog inputs.
Each channel has a separate menu. All
4-20 mA inputs can be configured using
the information provided in this section.
In this menu, the Sensor box displays
the live input reading in mA, and the
Value box displays the scaled
engineering units corresponding to the
sensor input. You can verify your
scaling parameters with this
relationship.

Display Preferences
Begin configuring the input by naming the channel (e.g. “Tank 1”.) This name appears on
screen to identify the channel during operation.
Move cursor to Channel ID and press EDIT. Use arrow keys to scroll through characters
and move to the next position. Press SAVE to store new setting to memory.
Next, set display options. Move cursor to Configure Display Parameters and press ENTER.
The box that appears contains the parameters for decimal point, engineering units, and
bargraph extents for this channel. Use EDIT and arrow keys. Remember to press SAVE
when finished.
Decimal Point
Format specifies the decimal point position for this channel. Use the arrow keys to
shift left or right (zero to five places.)
Units
Select from any available engineering units or choose to enter a combination of
characters by pressing the CUSTOM key. If this channel is to be used for integration
totalizing, do not select rate units as the integration time base is added separately.
Bargraph
Max Value and Min Value are used to set the span of the bargraph (in scaled
engineering units) for this channel. The bargraph will appear 100% full at Max Value
and 0% at Min Value.
