Set Analog Output (Aout)
With the repeater Analog Output, you can transmit the 4-20 mA signal to another
device such as a PLC or SCADA. The repeater can be scaled identically with the
4-20 mA input signal (repeating the input current) or scaled to a smaller span
(range of the input current). The Analog Output uses a two point linearization
based upon the Empty and Full settings. Note: When using the Analog Output,
the (Aout) must be configured to ensure that the repeater scale (Empty and Full
settings) matches the input current. Otherwise, the repeater output may be
scaled differently than the input leading to unexpected values. Before
configuring the Analog Output, make sure that Set Scale (SCALE) is done. To
configure the Analog Output, follow the below steps.
1. Press MENU to enter the Main Menu and Units (unitS) will be the first available
menu option.
2. Press Up to scroll through the menu options until you reach Analog Output (Aout).
3. Press ENTER and Empty (ErnPtY) will appear.
4. Press ENTER to view the existing Empty (ErnPtY) setting. Press Right to move the
highlighted digit to the right and Up to increase the setting's value (that's typically
set at 4 mA for an empty tank).
5. Press ENTER to the save this setting and Full (FuLL) will appear.
6. Press ENTER to view the existing Full (FuLL) value. Press Right to move the
highlighted digit to the right and Up to increase the setting's value (that's typically
set at 20 mA for a full tank).
7. Press ENTER to save this setting and continue to the next function.
