3. Enter a value of 10504 into Test Select 2 (parameter 95).
4. Look at the value of Test Data 2 (parameter 94). If Test Data 2 is
zero, no parameters in this group are being limited. If Test Data 2
is non-zero, use the following table to determine which parameter
is being limited.
The parameter limit testpoints are cleared when you clear the faults.
Once you know which parameter(s) is being limited, you can
determine why the parameter was limited. In many cases, a link from
the limited parameter to another parameter will explain how the limit
value was reached. For example, a link to an analog input value.
