AC Input Voltage Too Low, DC Fuse | Blue Sea Systems P12 specs

Alert Screens and Diagnostics (continued)

AC Input Voltage Too Low

The minimum input voltage for the P12 Battery Charger is 90V AC. However, due to common voltage sags caused by spikes in power, the internal hardware of the P12 Battery Charger can continue to charge for brief periods below 90V AC. If the AC input voltage drops below 75V AC, the alert screen on the right will appear. While in this state the charger will cease to charge any batteries. Shut off power at the AC source for two minutes, and then restart. If the alert screen persists, attempt to use a different AC power source, or contact an electrician to diagnose the problem.

7521 AND 7522 BATTERY CHARGERS

AC Input Voltage too Low

Check for Proper AC Source

AC Input Voltage Too High

The maximum input voltage for the P12 Battery Charger is 265V AC. If the input voltage is above 265V AC the alert screen on the right will appear. In this state the charger will cease to charge any batteries. Shut off power at the AC source for two minutes and then restart. If the alert screen persists, attempt to use a different AC power source, or contact an electrician to diagnose the problem.

AC Input Voltage Too High Check for Proper AC Source

DC Output Voltage Too High

If at any point the charger detects a DC output voltage greater than 17.8V DC for five seconds, then the alert screen on the right will appear. In this state the charger will cease to charge any batteries in order to prevent damage. Shut off AC power for two minutes, and then restart. If the alert screen persists, shut off AC power and contact Blue Sea Systems for further assistance.

DC Output Voltage Too High

Charger is off to prevent damage

Disconnect AC for 2 mins. then restart

DC Fuse

The P12 Battery Charger has two internal DC fuses that are not accessible by the user. If the DC Fuse Alert Screen appears, 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.

CAUTION

Any attempt to replace the DC fuses will void warranty.

Internal Fuse Failure.

Hardware Failure

There are many complex internal electrical components on the P12 Battery Charger. If any of the vital hardware components fail the Hardware Failure Alert Screen will appear. Shut off AC power for two minutes, and then attempt to restart. If there is no longer a Hardware Failure Alert Screen, proceed to use the charger normally. If the Hardware Failure Alert Screen persists, disconnect AC power and all battery connections, and contact Blue Sea Systems for further assistance.

Hardware Fault

Turn Off AC For 2 Minutes

Then Turn Power On

Equalization Overload

If at any point during equalization the total output current of the battery charger is greater than the defined Maximum Equalization Current the Equalization Overload Alert Screen will appear. To correct, confirm batteries are fully charged, and all loads are turned off prior to equalization. If mandatory 24-hour loads are present you may adjust the Maximum Equalization Current accordingly. Once corrected, the equalization process must be restarted.

WARNING

Increasing the Maximum Equalization Current beyond your battery manufacturers recommendations is potentially dangerous. Consult your battery manufacturer for proper equalization currents.

EQ stopped-Max Current Limit Make sure battery is charged and all loads removed!
