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.
