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 volt above or below the standard output voltage. The model BCA1000R

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.

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.

Installation

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:

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

draw from the 110 VAC supply is 14.6 amps, so a 15 amp circuit breaker should be used in the

circuit panel and for a 220 VAC supply, 7.3 amps is the maximum current draw, so a 10 amp

circuit breaker should be used in the circuit panel to feed power to the BCA1000R.

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.

110 VAC 220 VAC

Brown - AC Hot Brown - AC Hot / Phase 1

Blue - AC Neutral Blue - AC Neutral / Phase 2

Green - Ground Green/Yellow - Ground

Operation

Turn the switch on the front panel of the unit on to energize the outputs. The green ‘Power

On’ indicator light will glow to indicate the proper operation of the unit. The Digital Meter

will show the voltage and current on either output 1 or output 2. Flip the toggle switch to

view the voltage and current on the other output. If the battery is connected in parallel, then

you will have to add the currents on each output to see the total charging current.

OUTPUT ADJUSTMENT

The unit has an adjustment potentiometer to allow up to ± 1.0V adjustment of the output

voltage. This potentiometer is accessed through a small hole in the front panel of the Battery

Charger. As shipped from the factory, the unit is preset for a voltage of 13.6, 27.2, 36.3 or

A dry contact relay to indicate output failure is supplied standard. There is a plug just below

the main output connector that is used to connect to this relay. Simply determine if you

require a normally open or normally closed contact to indicate charger failure and connect

to the appropriate points on the plug. If you determine that the opposite function is required,

move 1 wire from the normally open connection to the normally closed connection.

If the batteries are connected in reverse, the output fuses will blow. Turn the unit off, correct

the wiring and then replace the fuses.

BATTERY TEMPERATURE SENSORS

Up to 2 battery temperature sensors can be connected to the charger to allow temperature

compensation of the battery charging voltage (1 is supplied with the unit). If only the 1 sensor

is used, it MUST be plugged into the ‘BATTERY 1’ connection on the rear of the unit. If no

sensor is used, the charger will default to standard output voltage.

The battery temperature sensor(s) must be physically attached to the battery bank(s) so that

it(they) can sense the temperature of the battery bank(s).

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.

A two-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 neces-

sary 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.

2 or 3 Stage Charging

54.4VDC. If you wish to adjust this voltage, rst locate the output adjustment potentiometer

access hole next to the diagnostic LED’s on the front panel. 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.

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.

Equalize

The charger includes a user selectable equalize function. The purpose of the equalize function

is to deliberately overcharge the battery to force any weak cells to recharge properly. This

function is required by most battery banks once every 2-3 months.

To start an equalize cycle, simply press the equalize button (located on the front panel) using a

pencil or pen. If the unit is charging (i.e. Charge light is ON), the equalize light will blink until

the charging is complete. The Equalize LED will come on solid when the equalize cycle starts.

The equalize cycle feeds a low current (typically 10 percent of maximum charging current) to a

maximum voltage as shown on the specications.

This cycle runs for 3 hours and then the charger resumes normal operation. If a shorter time

is required, it can be programmed using the DIP switches on the small equalize circuit board

inside the charger. (See below)
