1. Charging:

SOLID ON (Green): Indicates Charging mode and will operate according to its charging stage.

BLINKING (Green): Transitioning from Standby to a Charging state.

OFF: Standby mode - will not charge a battery or supply current to loads.

2. Charge Stage:

Bulk-BLINKING (Green): Indicates Bulk stage on all batteries
Absorb - BLINKING (Green): Indicates Absorb stage on all batteries
Prefloat*- SOLID ON (Green): Indicates PreFloat stage on any of three batteries

3. Fan Mode:

SOLID ON (Green): Indicates fan LOW or HIGH mode.

SOLID ON (Yellow): Indicates fan OFF mode.

BLINKING (Yellow): Indicates that the fan is OFF and the charger is limiting its output current to protect from eventual overheating. If full output is desired, the

Fan Mode needs to be set to LOW or HIGH to keep the charger cool. If the fan is OFF the charger will limit its output based on its internal

temperature sense.

4. Charge Output:

SOLID ON (Green): Charge Output LEDs are used to monitor the output on three batteries and limit the output using the output button. In normal operation, the Charge

Output LEDs show the percentage of the absolute maximum current on each battery. The range of each individual percentage is as follows:

<5%: 0% ≥ output < 5%

10%: 5% ≥ output < 17.5 %

25%: 17.5% ≥ output < 37.5%

50%: 37.5% ≥ output < 62.5%

75%: 62.5% ≥ output < 87.5%

100%: 87.5% ≥ output < 100%

BLINKING (Green): Indicates that the charger is limiting its output. There are two situations where this could occur:

1) The output of the charger is being limited per the user’s output setting.

2) The charger is limiting output to protect itself from overheating. In this situation, the Charge Output will blink alongside the yellow Thermal Regulation Alert.

See P12 Batter y Charger User Manual for more details.
