OPERATION
1 If your battery is not fully charged, the charging meter will indicate current drawn. As the battery approaches
being fully charged, the charging current will decrease.
2 When the meter reads zero, the battery is fully charged. These chargers are fully automatic and require no
maintenance in normal operation.
3 An overload condition caused by an accidental, external short circuit or defective, internally shorted battery,
will shut down the charger. The ON status LED will turn off. On removal of the short circuit condition, the
charger will automatically resume charging.
4 Short-term overload caused by charging a completely discharged good battery will not damage the charger.
5 A boat engine or generator can be started without unplugging or disconnecting the battery charger.
6 Nickel-cadmium batteries and nonchargeable batteries must not be charged with the charger. The casing of
these batteries can burst .
CHANGING BOOST VOLTAGE
The boost voltage is pre-set at 14.3 V for SEC-1215A and SEC-1230A, and 28.6 V for SEC-2415A. This boost voltage
can be changed to 14.9 V for SEC-1215A and SEC-1230A, and 29.8V for SEC-2415A. The procedure for this is as
follows:
1 Remove the 4 screws on the ammeter side of the top cover
2 Gently slide the top cover out by about 2 to 3 inches. (CAUTION! The top cover will be restrained from
fully sliding out by the wires connecting the ammeter, LED and fan)
3 Locate the slider switch marked SW 1 located near the connection for the output terminals. Slide the switch
over to the other position
4 Replace the top cover.
COOLING AND THERMAL OVERLOAD SHUTDOWN
CAUTION! KEEP THE UNITS IN A WELL VENTILATED COOL OPEN AREA. DO NOT BLOCK THE VENT HOLES ON
THE SIDES OR THE SUCTION OPENINGS OF THE COOLING FAN.
SEC-1215A is cooled by convection. It does not have thermal overload shutdown.
SEC-1230A and SEC-2415A are cooled by convection as well as temperature controlled fan. Two temperature
sensors mounted on the power transformer control the switching of the fan and over temperature shutdown. The
fan will be switched on when the power transformer reaches 70
°
C. HENCE, AT LOWER LOADS, THE FAN MAY NOT
CUT IN AND WILL BE OFF. THIS IS NORMAL. If the fan fails or if the cooling is not adequate due to poor
ventilation, the second temperature sensor will shut down the unit when the power transformer reaches 100
°
C.
The unit will automatically reset once the unit cools down.
