11.5 Error Detection Time
Basically it is not possible to specify an accurate error detection time, since times
depend on many factors and error reasons. The time period until a frequency error is
detected is another such as for example an analogue error. For simplification, it can be
assumed that the errors are detected after 85 ms plus the tripping time. As an exception
of this, detection of frequency errors could also take longer, since these times are
related to the input frequency and to parameter settings. Typical respond times for
various outputs and for frequency errors can be found in chapter “Response time”.
The error detection time depends (amongst others) on the following factors:
• Type of error
•
Parameter settings
•
External events and actions
•
Tnternal events and actions
• Respond time of the output
