Rosemount 5400 Series
Analog Output For the analog output. the Output Source (Primary Value), Range Values, and
Alarm Mode are specified.
Figure 5-6. Standard Range
Value settings.
Output Source/Primary Variable
Specify the source to control the analog output. Typically, the Primary Value is
configured to be the Product Level.
Upper/Lower Range Value
Enter the range values that correspond to the analog output values 4 and 20
mA. The 20 mA point should be set below the Transition Zone, since the
measurement accuracy is reduced in this region. For information on the
Transition Zone, see “Specifications” on page A-1.
If a measured value goes beyond the measurement range, the transmitter
enters saturation mode (if limit alarm is disabled) or alarm mode, depending
on the current configuration.
Alarm Mode
Choose the desired Alarm mode to specify the analog output state when there
is a failure or a measurement error.
High: the output current is set to the High Alarm Limit.
Low: the output current is set to the Low Alarm Limit.
Freeze Current: the output current is set to the last valid value at the time
when the error occurs.
