Chapter 5 – Troubleshooting
In general, the first step to troubleshooting should be to inspect the status LEDs on the SJ/L-EN board, in
addition to the inverter operator/keypad display. These will give valuable clues to the nature of the problem.
Refer to the description of the proper LED indications on page 11.
In addition, the inverter operator/keypad (if installed) will provide diagnostic information for certain types of
errors.
The error code for a communication error is:
