Low-Flow Cutoff (Cutoff); Analog Output Programming (Aoutpr) - FlowLine DataView LI55 Instruction Manual

DataView™ LI55 Level Controller
Low-Flow Cutoff ( CutofF )
The low-flow cutoff feature allows the meter to be programmed so that the often-
unsteady output from a differential pressure transmitter, at low flow rates, always
displays zero on the meter.
The cutoff value may be programmed from 0 to 999999. The meter will display
zero below the cutoff value. Programming the cutoff value to zero disables the
cutoff feature.
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)
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 loop 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.

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.
