Note:
1.
The LEDs indicate one trouble at a time.
2.
The LEDs indicate the latest trouble, after that trouble is cleared it will show the next trouble. For example, if there are a total of
three troubles in the sequence of:
- NAC short (oldest)
- Extra card
- Charger trouble (latest)
The LEDs first indicate the latest trouble: the charger trouble. After you clear the trouble, the LEDs indicate the extra card trouble
and then the NAC short trouble.
3.
All LEDs remain OFF if the system is normal.
