(c) Countermeasures for abnormal completion
Flashing of the ERR. LED indicates abnormal completion.
• If the 7-segment LED shows "Eb" and "EC" an error occurred during the initialization setting.
• If the 7-segment LED is off and only ERR. LED flashed, a system error is present.
When any error has occurred, take initialization steps again. If failure is detected again, any hardware error
may exist. Please consult your local Mitsubishi service center or representative, explaining the details of the
