CHARGER LED INDICATORS
The charger includes three (3) LEDs to indicate charger status and fault information. The
functionality of the LEDs is outlined below. If the charger is equipped with a remote LED
assembly, this assembly also includes three (3) LEDs with identical functionality.
YELLOW
Indicates charge cycle status. See descriptions of the possible states.
GREEN
Indicates when a charge cycle completes successfully, when an extended Equalize charge
cycle phase is active, or when a post-charge float phase is active. See descriptions of the
possible states.
RED
Indicates when a charger or battery fault has occurred. See descriptions.
