Damping output 
Navigation  Setup → Advanced setup → Curr.output 1 to 2 → Damping out.
Description Define time constant τ for the damping of the output current.
User entry 0.0 to 999.9 s
Factory setting 0.0 s
Additional information Fluctuations of the measured value affect the output current with an exponential delay,
the time constant τ of which is defined in this parameter. With a small time constant the
output reacts immediately to changes of the measrued value. With a big time constant the
reaction of the output is more delayed. For τ = 0 (factory setting) there is no damping.
Failure mode 
Navigation  Setup → Advanced setup → Curr.output 1 to 2 → Failure mode
Prerequisite Current span (→  140) ≠ Fixed current
Description Select behavior of the output current in case of an error.
Selection • Min.
• Max.
• Last valid value
• Actual value
• Defined value
Factory setting Max.
Additional information Meaning of the options
• Min.
The current output adopts the value of the lower alarm level according to the Current
span parameter (→  140).
• Max.
The current output adopts the value of the upper alarm level according to the Current
span parameter (→  140).
• Last valid value
The current remains constant at the last value it hat before the error occurred.
• Actual value
The output current follows the actual measured value; the error is ignored.
• Defined value
The output current assumes the value defined in the Failure current parameter
(→  142).
The error behavior of other output channels is not influenced by these settings but is
defined in separate parameters.
