Alert Screens and Diagnostics
(continued)
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 Fuse
The DC output fuses have opened. The fuses are user serviceable. Please follow the procedure on Page 8 under the
Maintenance section for details on procedure and replacement fuse ratings.
WARNING
Before replacing fuses, check all wiring connections for proper polarity. A reverse polarity condition on the DC wiring
may be the cause of the fuse failure.

AC Input Voltage Too Low
If the AC input voltage drops below 85V 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.
AC Input Voltage Too High
If the input voltage rises 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 Low
Check for Proper AC Source
AC Input Voltage Too High
Check for Proper AC Source
DC Output Voltage Too High
Charger is off to prevent damage
Disconnect AC for 2 mins. then restart
EQ stopped-Max Current Limit
Make sure battery is charged
and all loads removed!
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 manufacturer’s recommendations is potentially
dangerous. Consult your battery manufacturer for proper equalization currents.
