6.37 Analog Output (1-4) Menu – Retransmit Mode
(only appears if one or more 4-20 mA output option cards are installed)
4-20 mA Output Control Mode
Click on the pull-down to select between Not Used , Proportional Feed and Retransmit control
mode. This section assumes that the control mode is set to retransmit.
Input Assignment
Click on the arrow to pull down the choices of which sensor measurement will be retransmitted as
a 4-20 mA signal. The choices are any of the sensor inputs, any of the sensor’s temperature
compensation inputs, LSI, RSI, any paddlewheel flow meter or any 4-20 mA input signal (only if
the 4-20 mA input option is installed).
Input Status
This column shows the status of the sensor that has been mapped to the 4-20 mA output. Possible
messages include Normal, Unmapped, and Sensor Error.
Input Reading
This column shows the process value of the input that is mapped to the 4-20 mA output. This will
be in units of conductivity, pH, ORP, temperature or whatever the 4-20 mA input is using for units
of measure.
Output mA Value
This column shows the status of the 4-20 mA output in mA.
Output Status
This column shows the status of the 4-20 mA output in %, as well as any error messages. It will
read Normal if the input value is between the two programmed values defining the 4-20 mA
output, or Over Range if the input is above the 20 mA value, or Under Range if it is below the 4
mA value.
Custom Name
Type the name you want to use to identify this output into the text box.
