Chapter 7 - Fault Conditions
7.1 Fault Codes and Numbers (in History)
A three-character fault code is displayed in the LED display at the time of the trip
event. For instance, if Function F003 (overload protection) is set too low for the
size of the load, the code “oLA” will be displayed. Its corresponding number will
be entered into the fault history. In this case, the number 0010 will be available for
display in the window of function F075 (Fault History). The time the fault was
detected is available in Function F076. It is expressed as hh.mm. So if the “oLA”
fault occurred at 10:00 am, F076 would display 10.00. The date the fault occurred
is available in Function F077. The date is expressed as mm.dd. So if the “oLA”
fault occurred on March 1, F077 would display 03.01.
If there are no fault conditions in history, the display in F075 would read 0000.
