Select Menu (
SElect
)
The
Select
menu is used to program the analog output parameters. There are no other selections for this
model.
Analog Output Programming (
AoutPr
)
The
Analog Output Programming
menu is used to program the behavior of the 4-20 mA output. The
following parameters and functions are programmed in this menu:
1. Source: Source for generating the 4-20 mA output (e.g. PV - temperature)
2. Overrange: Analog output value with display in overrange condition
3. Underrange: Analog output value with display in underrange condition
4. Break: Analog output value when input break is detected
5. Max: Maximum analog output value allowed regardless of input
6. Min: Minimum analog output value allowed regardless of input
7. Calibrate: Calibrate the internal 4-20 mA source reference used to scale the 4-20 mA output
Analog Output Source
The source for generating the 4-20 mA output may be assigned to the process variable, maximum or
minimum value reached by the process, one of the set points, or the Modbus PV input.
Analog Output Calibration
To perform the analog output calibration, it is recommended to use a milliamp meter with a resolution of
at least 0.1 µA to measure the output current. The values saved internally during this procedure are used
for scaling the 4-20 mA output in the
Setup
menu.
