Function description
INPUTS CURRENT INPUT CONFIGURATION
ASSIGN CURRENT
INPUT
(5200)
Use this function to assign a process variable to the current input.
Options:
OFF
TEMPERATURE
PRESSURE
REFERENCE DENSITY
Factory setting:
OFF
CURRENT SPAN
(5201)
Use this function to define the current range. The selection specifies the operational range
and the lower and upper signal on alarm.
Options:
0–20 mA
4–20 mA
4–20 mA NAMUR
4–20 mA US
0–20 mA (25 mA)
4–20 mA (25 mA)
Factory setting:
4–20 mA NAMUR
! Note!
When switching the hardware from an active (factory setting) to a passive output signal,
select a current range of 4–20 mA (See Operating Instructions Proline Promass 83, BA
059D/06/en/).
Current range / operational range (measuring information):
0–20 mA / 0...20.5 mA
4–20 mA / 4...20.5 mA
4–20 mA NAMUR / 3.8...20.5 mA
4–20 mA US / 3.9...20.8 mA
0–20 mA (25 mA) / 0...24 ma
4–20 mA (25 mA) / 4...24 mA
VALUE 0_4 mA
(5202)
Use this function to assign a value to the 0/4 mA current.
User input:
5-digit floating-point number
Factory setting:
Dependent on the process variable assigned to the current input (see function ASSIGN
CURRENT INPUT, 5200).
– Pressure: 0 barg
– Temperature: –50 °C
– Reference density: 0.50 kg/Nl
! Note!
The appropriate unit is taken from the functions UNIT PRESSURE (0426), UNIT
TEMPERATURE (0422) or UNIT REFERENCE DENSITY (0421).
