12V (e.g. due to a high load on the batteries), the entire charging
cycle will be repeated.

Troubleshooting

Unit is not working at all (no LEDs)
After you have started the engine, check the voltage at the main
alternator input of the unit. You should be able to measure at least
13V. If you do not measure any voltage at all, it is possible that
your alternator requires a voltage on the output to fire up. (See
Extended Installation.) In this case connect an extra wire from the
terminal named "STARTER SOLENOID" to the positive terminal
of the starter solenoid.
If the input voltage on the unit is 13V or above and you still can't
see any LEDs lighting up, check the internal fuse
and replace if necessary. If the new fuse blows again, please
contact the Sterling customer service.
Unit is not boosting the voltage
Most regulators come set with a standard output between about
13.8V and 14.4V. If the standard regulator does not work within
these limits and has an output voltage below 13.8V, then the unit
may not boost. In this case set the regulation voltage switch
to the "ON" position. This will drop the engine battery charge from
appr. 13V to appr. 12.8V which in turn improves the boost effect
on the domestic battery side.
Warning: Do not do this unless you have the above-described
problem as this could result in a low engine start battery
performance.
Appendix 1: LED Information and Alarms
LED 1 - CONSTANT CURRENT (green)
A constant green LED (with LED 2 off) indicates that the unit is in
the bulk charge phase.
A flashing green LED indicates that the unit is in pause mode to
provide additional charge capacity for the starter battery.
LED 2 - TIME CONTROL ON (yellow)
This LED indicates that the voltage is approaching or has
reached the absorption level. It will come on only in addition to
LED 1.
LED 3 - FLOAT/POWERPACK (green)
This LED indicates that the absorption charge has been finished
and that the batteries have been fully charged. It remains on until
the unit is switched off or until the next charge cycle starts.
LED 4 - LOW BATTERY V (orange)
This LED will come on when the domestic battery voltage as
sensed by the unit, is below 13V. Often this indicates a defective
alternator or battery.
LED 5 - HIGH BAT V/ TEMP (FL) (red)
A constant red LED means that the unit has tripped because of
high voltage at the domestic battery. Often, this indicates a failure
of the alternator regulator or another charging unit.
A flashing red LED means that the domestic battery temperature,
as sensed by the unit, is above 50°C and that the charge cycle
has been suspended. Often, this indicates a defective battery.
LED 6 - BATTERY TYPE (yellow, green, red)
This LED displays the battery type that the unit has been set up
for. It will be
yellow, for open lead-acid batteries,
green, for gel batteries (Exide specification)
flashing green, then off, for gel batteries (U.S. specification),
and
red, for sealed lead-acid and AGM batteries.
LED 7 - HIGH ALT VOLTS (red)
This LED indicates that the unit has tripped because of high

voltage (> 15.5V) on the alternator. It usually means that the
alternator's own regulator has failed.
necessary, stop your engine as soon as possible and disconnect
the alternator input cable, or you will boil and destroy your
batteries!
LED 8 - HIGH ALT TEMP, STOP (yellow)
This LED will come on when the alternator temperature as
sensed by the unit, is above 90°C. The charge cycle will be
suspended until the alternator has cooled down to 75°C or below.
A flashing yellow LED means that the alternator-to-battery
charger is overheated. The charge cycle will be suspended until
the unit has cooled down. If this fault occurs regularly, then the
unit must moved to a cooler location to protect it from permanent
damage.
LED 9 - UNIT FAILURE RHS (red)
This LED warns you that the unit's integrated split charge diode
has failed on the right hand side. Restart the unit. If the fault
persists, please contact the Sterling customer service.
LED 10 - UNIT FAILURE LHS (red)
This LED warns you that the unit's integrated split charge diode
(14)
has failed on the left hand side. Restart the unit. If the fault
persists, please contact the Sterling customer service.
