ALL BATTERY CHARGERS

1. WARNING — RISK OF EXPLOSIVE GASES.

i. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES

GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS

REASON, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE SERVICING

EQUIPMENT IN THE VICINITY OF THE BATTERY, YOU READ THIS MANUAL AND

FOLLOW THE INSTRUCTIONS EXACTLY.

ii. To reduce risk of battery explosion, follow these instructions and those published

by battery manufacturer and manufacturer of any equipment you intend to use in

vicinity of battery. Review cautionary marking on these products and on engine.

2. PERSONAL PRECAUTIONS

i. Someone should be within range of your voice or close enough to come to your aid

when you work near a lead-acid battery.

ii. Have plenty of fresh water and soap nearby in case battery acid contacts skin,

clothing, or eyes.

iii. Wear complete eye protection and clothing protection. Avoid touching eyes while

working near battery.

iv. If battery acid contacts skin or clothing, wash immediately with soap and water.

If acid enters eye, immediately ood eye with running cold water for at least 10

minutes and get medical attention immediately.

v. NEVER smoke or allow a spark or ame in vicinity of battery or engine.

vi. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark

or short-circuit battery or other electrical part that may cause explosion.

vii. Remove personal metal items such as rings, bracelets, necklaces, and watches

when working with a lead-acid battery. A lead-acid battery can produce a short-

circuit current high enough to weld a ring or the like to metal, causing a severe burn.

viii. NEVER charge a frozen battery.

ix. If necessary to remove battery from service, always remove grounded terminal from

battery rst. Make sure all accessories in the vessels are off, so as not to cause an

arc.

x. Be sure area around battery is well ventilated.

xi. Clean battery terminals. Be careful to keep corrosion from coming in contact with

eyes.

xii. Study all battery manufacturer’s specic precautions such as removing or not

removing cell caps while charging and recommended rates of charge.

xiii. Add distilled water in each cell until battery acid reaches level specied by battery

manufacturer. This helps purge excessive gas from cells. Do not overll. For a

battery without cell caps, carefully follow manufacturer’s recharging instructions.

GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS

The plug must be plugged into an outlet that is properly installed and grounded in accordance

with al local codes and ordinances.

DANGER Never alter AC cord or plug provided — if it will not t outlet, have proper cord

installed by a qualied electrician. Improper connection can result in a risk of an electric

shock.

Introduction

All new Current Mode switching design offers increased power and reliability in a compact

package. Extra input and output ltering reduce EMI to extremely low levels. Reliability

features include an input fuse, thermal shutdown, current limiting, reverse battery hookup

protection and output short circuit shutdown with automatic recovery. The output voltage

is easily adjusted 1.0 volts above or below the standard output voltage. The model

BCA1000 Battery Charger supplies either 12, 24, 32 or 48 VDC from a 110 or 220 VAC power

source. High quality digital meters can be added (factory option) to allow monitoring of

charging current and charging voltage. A remote control option or equalize & temperature

compensation (factory installed) option is available for this model.

Features

In a DC UPS ( Un-interruptible Power Supply ), the charger simultaneously powers the DC load

as well as the battery. As long as the AC power to the charger is available and the charger is

working normally, the charger will supply the DC load as well as charge / oat the battery. In

case the AC power fails or if the charger stops working, the battery will automatically power

the DC load. As soon as the AC power to the charger is restored, the DC load will once again

be fed by the charger and at the same time the battery will be recharged.

CAUTION! Please ensure that the sum of the current drawn by the DC load and the current

desired for charging the battery is less than the maximum current capacity of the charger. To

use as a DC UPS, rst switch off the DC load and connect it to the battery. Now connect the

battery. Switch on the charger and then switch on the DC load.

MOUNTING

Mount the unit in a DRY location. Allow at least 4 inches of clearance around the heat sink

ns for adequate cooling.

POWER CONNECTION

The unit is supplied with a power cable 5 feet long. This should normally be adequate to

connect to a source of power. 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. The wire colours are: to connect to a source of power. If you must

extend the power leads, be sure to use at least a good quality (typeTEW) AWG 8 gauge wire.

The wire colours are:

All connections should be made inside an appropriate junction box. The maximum current

draw from the 110 VAC supply is 13.8 amps, so a 15 amp circuit breaker should be used in the

circuit panel and for a 220 VAC supply, 6.9 amps is the maximum current draw, so a 10 amp

circuit breaker should be used in the circuit panel to feed power to the BCA1000.

OUTPUT CONNECTIONS

Two Positive output terminals and two Negative output terminals are provided. Connect only

one wire to each terminal. Ensure that the total average load connected does not exceed the

continuous current rating of the unit.

To ensure spark free connections the power switch must be in the OFF position prior to making

the connections to the battery bank(s).

The charger may be hooked to 1 or 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! If you are going to hook up one battery bank to the charger, you may hook up the

outputs in parallel to reduce stress on the output isolation diodes inside the charger.

Operation

Prior to turning on the unit, you must decide on which charging prole, 2 or 3 stage charging,

to use. To help you decide, please see the following section entitled 2 or 3 Stage Charging to

determine the charging prole.

Once you have decided on the charging prole you must set the switch to the correct

position. To access the switch remove the cover plate (secured by 2 screws). Set the switch

to the correct position as shown on the label. When you are done, replace the cover plate

and securely tighten the screws.

To turn the unit on, simply move the power switch to the ON position. The alarm buzzer will

sound and the Low Output LED will come on briey, and then the green OUTPUT ON LED will

illuminate.

When the unit is rst turned on, it will charge the batteries at a constant current and

the charging light will be on. After a period of time, which may be minutes to hours, the

batteries will reach the oat voltage at which time the charging light will go off, and the

charging current will reduce as necessary to maintain the batteries at that voltage. You

may check this voltage at the output terminals of the unit with a good digital voltmeter. As

shipped from the factory, the unit is preset to 13.6, 27.2, 36.3 or 54.4 VDC, which is generally

recommended for lead-acid batteries. If you wish to adjust the charging voltage, remove the

cover plate (secured by 2 screws) to expose the output adjust potentiometer. Reach in with a

very small at blade screwdriver to rotate the potentiometer. Clockwise increases the output

voltage, and counter clockwise decreases it. When you are done, replace the cover plate and

securely tighten the screws. It is advisable to check with the battery manufacturer before

changing the oat voltage.

High quality digital meters can be added to the charger (factory installed only). Both outputs

can be monitored for current and voltage

Meters

Atwo-stage charger provides a constant current until the battery reaches its rated capacity

and then switches to a “oat” voltage. The current then reduces as necessary to maintain

the battery at the oat voltage. The charger can be connected to the battery indenitely and

will provide the appropriate prole. A two-stage charger is recommended in most instances

since it is the most versatile and can be permanently connected to attenuate the characteristic

discharge of unused batteries. A load can be put on the battery or batteries without altering

its ability to keep the battery at optimal charge.

Three Stage Charger

Amps

A three-stage charger is the fastest charger. It charges the battery at a constant current

until the battery voltage reaches a slightly elevated level. The battery is maintained at

this voltage while the charging current diminishes to a low value, and then the battery is

switched to the oat voltage where it can be maintained indenitely. However, the charger

cannot differentiate between a current going to a load on the battery, or being absorbed by

the battery, so it can overcharge a battery supplying current to a load. A two-stage charger

is preferred for “loaded” batteries and a three-stage for idle or unloaded batteries during

recharging.

All of Analytic Systems’ chargers include adjustable output voltage for charging standard or

deep cycle lead-acid, VLRA or gel type batteries.

This charger features user selectable 2 or 3 stage charging. The charging prole is selected by

moving the slide switch on the front panel left to 3 stage or right for 2 stage charging.

Troubleshooting

This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should

sound the buzzer to alert you prior to shutting itself down. You should immediately check the

indicators to determine the cause of the shutdown.

LOW OUTPUT Indicates that the output voltage is below normal because:

• The current demanded by the devices connected to the unit exceeds the maximum

output current rating, causing the output voltage to drop to maintain the current at

the maximum level

• The input voltage is not high enough for unit to operate,

LOW INPUT Indicates that the input voltage is below normal because:

• The input voltage is not in the correct range for proper operation of the unit.

OVERTEMP Indicates that the Battery Charger is running too hot because:

• Too much power is being drawn, turn off or unplug some devices.

• The Battery Charger is located in a poorly ventilated area.

• If the load exceeds the continuous rating for too long a period, the temperature

sensor inside the unit will turn off the outputs. After the unit cools sufciently, it

will automatically come back on. If this happens frequently, remount the unit for

increased airow so it cools better.

CHARGING Indicates that the battery charger is charging the batteries:

• If the LED is not on, the batteries may be fully charged and the charger is supplying a

oat voltage to the batteries to keep them fully charged.

If the load exceeds the continuous rating for too long a period, the temperature sensor inside

the unit will turn off the outputs. After the unit cools sufciently, it will automatically come

back on. If this happens frequently, remount the unit for increased airow so it cools better.

Dry Contact Relay

To use your dry contact output fail relay you must connect a 9-pin D connector to the unit.

You must use pins one and six as is indicated on page 9 in the remote connector diagram.

The relay is factory preset to fail in the closed position when the low output LED and buzzer

come on. If you wish to have the relay fail in the open position when the low output LED

and buzzer come on, you must take the cover off the unit and move the jumper to the other

position on J22. J22 is located next to the relay.
