Troubleshooting using the LED indicators
Section 5-1
Tip
Do not clear the trip before you are finished troubleshooting an error. When
you clear the trip, the error code is cleared from the four-digit display. The trip
history can however be read back using d080 through d086. This will allow
you to diagnose the error even if you accidentally cleared the trip cause.
