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.

Alerts and Diagnostics

5. Thermal Regulaton:

SOLID ON (Yellow): The charger temp output limit LED indicator will blink to notify the user that the charger is limiting its output to protect itself from eventual overheating. The

most common correction for this state is to increase the fan speed to High. If the fan speed is already set to High check for blockage around the fan vent that can be removed.
If the condition persists, it is advisable to reposition the battery charger in a cooler, more ventilated location. See P12 Battery Charger User Manual page 20 for more details.

6. Internal Temperature Sensor:

BLINKING (Red): Indicates a problem with the thermistor temperature sense internal to the charger. If that is the case, the charger will immediately go into standby mode.
This form of temperature alert can not be corrected by the user. Contact Blue Sea Systems for further information regarding internal temperature sensor alerts.

7. Battery Temperature Sensor:

BLINKING (Red): Indicates the battery temperature is out of range. The charger will not charge a battery exceeding temp limits and will therefore go into standby

mode immediately. The remote will signal its alarm. If at any point the temperature sensor records a temperature beyond the defined temperature limits, the battery
charger will display the Battery Temperature Alert Screen. In this situation all battery charging will stop until the proper battery temperature is restored. Normal operation
will not commence unless two degrees within the temperature parameters. See P12 Battery Charger User Manual page 20 for more details.

8. Fan:

BLINKING (Red): Indicates the chargers’ internal fan is not working properly. See P12 Battery Charger User Manual page 20 for more details.

9. DC Fuse:

BLINKING (Red): Indicates the chargers’ internal DC fuse is blown. The P12 Battery Charger has two internal DC fuses that are not accessible by the user. Disconnect AC
power and all battery connections. The battery charger will require servicing by Blue Sea Systems. No attempts should be made to replace the fuses by the user. Contact Blue
Sea Systems for further instructions regarding DC fuse replacement.

10. AC Input Voltage Too High or Low:

BLINKING (Red): Indicates charger AC power is out of range. See P12 Battery Charger User Manual page 21 for more details.

11. DC Reverse Polarity or Short Circuit:

BLINKING (Red): Indicates a reverse polarity or short circuit condition is present on the DC output. The remote will signal its alarm. See P12 Battery Charger User Manual
page 20 for more details.

12. Hardware Failure, DC Output Voltage Too High, Equalization Overload: ALL ALERT LEDs BLINKING (Red): Indicates fault state.

Go to the P12 Battery Charger to see the pop-up screen explaining the reason.

13. Fan Mode:

Press to scroll through fan mode selections OFF, LOW or HIGH.

See P12 Battery Charger User Manual for more details.

14. Dim /Alarm:

- Normal operation: Press to Dim LED brightness.

- Fault Condition: Press once to silence Alarm buzzer.

15. Output:

Limits the charger’s output to a certain percentage of its absolute maximum. Press the output button once to show the current output setting on Charge Output LEDs. Press

again to scroll through settings. The setting is shown via a row of solid LEDs correlating to the percentage. The user can set the output from 100% down to 25%.

16. Standby:

Puts the charger in Standby mode. If the charger is in charging mode, press once to go to Standby. If in Standby, press once to start charging again.

A blinking charging LED indicates the charger is transitioning from Standby to Charging.

See P12 Battery Charger User Manual for more details.
