11.4 Function group STATUS OUTPUT
FAILSAFE MODE For reasons of safety it is advisable to ensure that the pulse output assumes a predefined
state in the event of a fault. Use this function to define this state.
Options:
FALLBACK VALUE
Output is 0 pulse.
ACTUAL VALUE
Measured value output is based on the current flow measurement. The fault is ignored.
Factory setting:
ACTUAL VALUE

Function group STATUS OUTPUT
ASSIGN STATUS Use this function to assign a switching function to the status output.
Options:
NON CONDUCTIVE
CONDUCTIVE
FAULT MESSAGE
FAULT & NOTICE
LIMIT MASS FLOW
LIMIT VOLUME FLOW
LIMIT DENSITY
LIMIT TEMPERATURE
LIMIT EXCITATION CURRENT
Factory setting:
FAULT MESSAGE
!
Note!
The behavior of the status output is of the quiescent-current type, in other words the
transistor is conductive when normal, error-free measuring is in progress.
ON VALUE
!
Note!
This function is not available unless an option LIMIT was selected in the ASSIGN
STATUS function.
Use this function to assign a value to the on-value (activation of the status output).
User input:
Multi-digit floating-point number
OFF VALUE
!
Note!
This function is not available unless an option LIMIT was selected in the ASSIGN
STATUS function.
Use this function to assign a value to the off-value (deactivation of the status output).
User input:
Multi-digit floating-point number
