CONFIGURATION
ASSIGN CURRENT
(5200) Use this function to assign a process variable to the current input.
Options:
OFF
TEMPERATURE
DENSITY
Factory setting:
OFF
CURRENT SPAN
(5201) Use this function to define the current span. This selection defines the operational range
and the upper and lower 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 span of 4 to 20 mA (see Operating Instructions Promag 55, BA119D/06).
Current span / operational range (measuring information):
0–20 mA / 0 to 20.5 mA
4–20 mA / 4 to 20.5 mA
4–20 mA NAMUR / 3.8 to 20.5 mA
4–20 mA US / 3.9 to 20.8 mA
0–20 mA (25 mA) / 0 to 24 mA
4–20 mA (25 mA) / 4 to 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, 5200).
– Density: 0.5 kg/l
– Temperature: –50 °C

Note!
The appropriate unit is taken from the functions UNIT DENSITY (0420) or
UNIT TEMPERATURE (0422).
