CURRENT SPAN (4001) Use this function to define the current span. 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
Current span, operational range and signal on alarm level
A0001222
A = Current span
1 = Operational range (measuring information)
2 = Lower signal on alarm level
3 = Upper signal on alarm level
!
Note!
• If the measured value exceeds the measuring range (as defined in the functions
VALUE 0_4 mA (4002) and VALUE 20 mA (4003)) a notice message is generated
(#351–354, current span).
• In case of a fault the behaviour of the current output is according to the selected
option in the function FAILSAFE MODE (4006.) Change the error category in the
function ASSIGN SYSTEM ERROR (8000) to generate a fault message instead of a
notice message.
