CURRENT SPAN
(contd)
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 and VALUE 20 mA a notice message is generated (#351 to 352, current
span).
• In case of a fault the behaviour of the current output is according to the selected option
in the function FAILSAFE MODE. Change the error category in the function ASSIGN
SYSTEM ERROR to generate a fault message instead of a notice message.
VALUE 0_4 mA Use this function to assign a value to the 0/4 mA current, (see “Setting the span by
means of the 0_4 mA and 20 mA value” on Page 26).
! Note!
This function is not available unless the TEMPERATURE option was selected in the
ASSIGN CURRENT function.
Option:
5-digit floating-point number (with sign for the TEMPERATURE measured variable)
Factory setting:
0 °C or +32 °F (country dependent, → Page 71 ff.)
VALUE 20 mA Use this function to assign a value to the 20 mA current, (see “Setting the span by means
of the 0_4 mA and 20 mA value” on Page 26).
Option:
5-digit floating-point number (MASS FLOW, CORRECTED VOLUME FLOW and TEM-
PERATURE (with sign) measured variables)
Factory setting:
Depends on nominal diameter [kg/h; lb/h] or [Nm
3
/h; Sm
