13. LED INDICATORS
The charger includes one (1) local LED that can display three (3) colors to indicate charger status and fault
information (see Figure 5-1). The functionality of the LED is outlined below. If an optional remote LED is
being used, it will provide the same functionality.
Amber (Charge Status)
Indicates charge cycle status. See Figure 13-1 for descriptions of the possible states.
Green (Charge Status)
Indicates when a charge cycle completes successfully, when an extended Balance/Equalize charge cycle
phase is active, or when a post-charge phase is active. See Figure 13-1 for descriptions of the possible
states.
Red (Fault)
Indicates when a charger or battery fault has occurred. See the FAULTS section.
