Introduction

The BCA610 AC source battery charger provides up to 600 watts of precision charging power

to charge your one or two bank battery system. The batteries must share a common ground.

This unit can be built to operate from any conventional AC mains power of 110 or 220 VAC .In

the absence of a battery, the BCA610 can also function as a power supply up to its continuous

current rating. See Specications for the output current rating of your unit.

Suitable for all your battery charging needs, this unit can be congured to charge a 12, 24, 32,

or 48 volt battery bank. With the output voltage adjust and user-selectable charging proles,

you have optimal control in how you charge your batteries. Additionally, voltage temperature

compensation protects your expensive battery banks from overly harsh charging, prolonging

their lifespan.

Internally, the recently updated single board design incorporates time-tested switch mode

technology for unmatched efciency and ultra-quiet operation. Additional ltering on the input

and output reduce conducted and radiated EMI noise to very low levels.

Designed with safety in mind, this unit’s safety features include reverse input connection,

input fuse, over temperature shutdown, short circuit protection, input/output under voltage

shutdown, reverse battery connection and output overvoltage crowbar.

Mounting

Mount the unit in a DRY and WELL VENTI-

LATED location with at least 4 inches of

clearance all around it. The ideal mount-

ing conguration is to mount the unit at

on a horizontal surface. #10 screws are

recommended for attaching the unit to the

surface.

There is 1500 volts of isolation between

the input and output, and the input and

case. There is 500 volts (1500V for 48V

output units) of isolation between the output and case. Therefore, the unit may be mounted on

any surface without fear of electrolysis or ground fault.

Installation

All connections should be made inside an appropriate junction box with appropriately rated

circuit breakers used in the circuit panel to feed power to the BCA 610. See Specications for

the maximum input current and recommended fuses.

AC Input Connection

The unit is equipped with a 5-foot long power cable terminating in either a North American

outlet compatible NEMA 5-15 plug or European outlet compatible CEE-7/7 plug to serve as an AC

Input Connection.

If you must extend the power cable be sure to use a 3 conductor grounded type extension

cable. For hard wiring to a source of power, cut off the plug, and strip the wires as necessary.

Battery Temperature Sensor Connection

This unit is equipped with a pair of RJ45 “telephone jack” connectors to serve as connections

for up to 2 Analytic Systems battery temperature sensors. If only 1 sensor is being used, it

must be plugged into ‘BATT 1” port. This sensor communicates the temperature of the battery

to the charger, and is required for the voltage temperature compensation function, over

temperature shutdown and user-initiated equalize cycle.

There are multiple ways to install the sensor at the battery. Regardless of which method you

use, the sensor must be rmly secured to the battery. The sensor should not lose physical

contact with the battery at any point in the charging cycle.

Pictured: Analytic Systems Battery Temperature Sensor

Connect the battery bank(s) to the terminals using an appropriate gauge of wire for the charg-

ing amps. Ensure that the total average load connected to the batteries does not exceed the

unit’s charging amps. See Specications for this unit’s charging amps.

This connection can support up to 2 battery banks. Hook up the battery bank(s) as shown below.

If you are hooking up 2 battery banks keep in mind that they MUST share a common ground!

To install the sensor at the battery,

you may:

• Slide the sensor so it is ush

between the side of the battery and

battery platform.

• Place the battery on top of the

sensor to hold it in place.

•Apply a small amount of silicone RTV

sealant to the sensor and stick it to

the top of the battery.

Operation

The BCA610 is 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 prole using the Stage Select switch on the top panel.

See Charging Proles for more information.

2. Move the Power Switch to ON. The alarm buzzer will sound and the LOW VOLTAGE

OUTPUT LED will glow red briey, 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 voltage

1. Disconnect the battery temperature sensor(s) from the unit, if connected.

2. Move the Power Switch to ON.

3. Loosen the two screws and remove the cover plate on the top panel to access the output

voltage adjust potentiometer.

4. Using a small at-blade screwdriver, rotate the potentiometer.

5. The charging voltage can be adjusted over a range of ±10%. Rotate the potentiometer clock-

wise to increase the output voltage; counterclockwise to decrease the charging voltage.

6. Using a voltmeter or multimeter, check the charging voltage at the battery terminal.

7. When satised with the new voltage, return the cover plate to its original position, rein-

stall the screws and reconnect the battery temperature sensor(s)

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.

This unit features two user-selectable charging proles. You can choose which type of charg-

ing prole, two stage or three stage, is used to charge your batteries using the Stage Select

switch on the front panel. Below are explanations of the two proles:

In two stage charging, the battery is

charged with a constant current until

the battery voltage reaches the “oat

voltage”. The current then diminishes as

necessary to maintain the battery at this

voltage. Once the current drops to 10%

of it’s initial value, the battery is then

held at the “oat voltage”

Two stage charging is recommended in most instances since it is gentler on the battery. The

battery is subjected to lower charging voltages, a reasonable load can be put on the battery

without altering the charger’s ability to keep the battery at optimal charge.

In three stage charging, the battery is

charged at a constant current until the

battery voltage reaches the “absorption

voltage”. The battery is maintained at

this voltage while the current diminishes.

Once the current drops to 10% of it’s

initial value, the battery is then held at

the “oat voltage”

Three stage charging is faster than two

stage. However, the battery is subjected to higher voltages. In addition, the charger cannot

differentiate between current going to a load on the battery and current being absorbed by

the battery, so it can overcharge a battery powering a load.

This unit is tted with LED indicators and an alarm buzzer to display and diagnose any

problems in operation. In the event of a malfunction, the unit will sound the buzzer to alert

you prior to shutting itself down. You should immediately check which LEDs are glowing to

determine the cause of the alarm.

LED Indicator Meaning

BATTERY OVERTEMP The battery temperature is too high for safe charging.

Fix: The battery may be defective or there may not be adequate ventilation to

cool the battery.

Check that the battery is not defective. If it is working correctly, reposition

the battery for better air circulation.

OVERTEMP The unit’s internal temperature is too high for normal operation.

Fix: The internal cooling fan may have failed or there may not be adequate venti-

lation to cool the charger. Check that the cooling fan is still working; if it is

not then the unit must be returned to an authorized service center for repair.

If it is working correctly, remount the battery charger for better air circulation.

LOW INPUT The battery charger’s input voltage is too low for normal operation

Fix: Check that the power source is properly rated for the battery charger. Check

that the input cables and connection are free of damage and corrosion.

If all of the above are in proper working order, the cause is likely an internal

component failure and the unit must be returned to an authorized service

center for repair.

LOW OUTPUT The battery charger’s output voltage is too low for normal operation.

Fix: The charging current might be exceeding the unit’s maximum rating causing

the output voltage to drop to maintain the current at that level. Check

that the charging current is not over its limit, by using a multimeter at the

output terminals. If it is, reduce the load connected to the charger.

Check that the output cables and connections are free of damage and

corrosion.

If all of the above are in proper working order, the cause is likely an internal

component failure and the unit must be returned to an authorized service

center for repair.
