Battery Charger Operation (BCA)
The BCA1050/BCA1550 series battery chargers are designed for simple and intuitive
operation. Before operating, make sure this unit is properly installed and connected. See
Installation for more information.
TO CHARGE A BATTERY
1. Select the type of charging prole using the Stage Select switch on the front panel.
See Charging Proles for more information.
2. Move the Power Switch to ON. The alarm buzzer will sound and the LOW VOLTAGE
OUTPUT LED will glow red briey, then the POWER LED will glow green.
3. The CHARGING LED will glow green and the unit will charge the battery at the voltage
and current listed on the label.
4. Once the battery is fully charged, the CHARGING LED will turn off. The unit will maintain
the battery at full charge for as long as it is connected.
TO ADJUST THE CHARGING (FLOAT) VOLTAGE
The Output Voltage Adjust can be use to adjust the charging (oat) voltage ±1.0V from the
unit’s rated output voltage in order to ne-tune its charging capabilities.
1. On W-series and Y-series models the Output Voltage Adjustis protected by an O-ring
sealed hexagonal plug. This plug can be removed using a 5/8ths inch or 16mm wrench.
2. Move the Power Switch to ON.
3. Rotate the output voltage adjustment potentiometer on the front panel.
4. Rotating the potentiometer clockwise increases the output voltage; counterclockwise
descreases it.
5. Using a voltmeter or multimeter, check the charging voltage at the Output Connection.
Adjust until the voltage reading is suitable. If the unit has the optional digital meter, that
can be used to read the output voltage instead.
6. Replace the hexagonal plug to return the unit to water resistant condition.
TO END OPERATION
1. Move the Power Switch to OFF.
2. Wait for all the LEDs stop glowing.
3. Once all of the LEDs are off, it is safe to disconnect the unit from the power source and
battery. The unit is now ready for storage or service.
