Specifications are subject to change. See bluesea.com/P12 for current information.
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 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 page 20 for more details.
8. Fan:
BLINKING (Red): Indicates the chargers’ internal fan is not working properly. See 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 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 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.
