 Setup → Advanced setup → Current output 1 to 2 → Damping output
Reaction time of the output signal on fluctuation in the measured value.
0.0 to 999.9 s
0.0 s
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.
 Setup → Advanced setup → Current output 1 to 2 → Failure mode
Current span (→  151) ≠ Fixed current
Defines which current the output assumes in the case of an error. 'Min.': < 3.6mA 'Max.': >
21.95mA 'Last valid value': Last valid value before occurrence of the error. 'Actual value':
Output current is equal to the measured value; error is ignored. 'Defined value': User
defined value.
• Min.
• Max.
• Last valid value
• Actual value
• Defined value
Max.
Meaning of the options
• Min.
The current output adopts the value of the lower alarm level according to the Current
span parameter (→  151).
• Max.
The current output adopts the value of the upper alarm level according to the Current
span parameter (→  151).
• 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
(→  153).
The error behavior of other output channels is not influenced by these settings but is
defined in separate parameters.
