ALL BATTERY CHARGERS

1. 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 FOL-

LOW 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 vicin-

ity 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, cloth-

ing, 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 cur-

rent 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 remov-

ing 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.

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 posi-

tion. 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 maximum current and the

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

ies will reach the absorption voltage (3-stage) or oat voltage (2-stage), and the charging

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

current has dropped to a low level (about 15% of the charging current rating), the charging

All connections should be made inside an appropriate junction box. Refer to the specications

table for the correct sizing of the circuit breaker in the distribution panel.

A ground stud is provided to bond the chassis to local ground to reduce or eliminate EMI.

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 unit may be hooked to 1 or 2 battery banks depending on the model. 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!

light will go off, and if set to 3-stage charging the voltage will drop to the oat level. 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 for a oat voltage of 13.6, 27.2 or 54.4 VDC, which is gener-

ally recommended for lead-acid batteries. If you wish to adjust this 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. Please note that this adjusts both

the oat and absorption voltages at the same time. 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.

Meters

A high quality digital meter can be added to the voltage converter (factory installed only). The

meter shows simultaneous voltage and current on either of the two output terminals. A toggle

switch permits selection between the output terminals. The meter features bright red LED

readouts to permit easy monitoring from many feet or meters away.

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 ‘BATT 1’ connection on the side of the unit. If no sensor

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

For installation isnstructions of the temperature sensor, please see the section entitled

Remote Battery Temperature Sensor Installation

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 up to 3 stage or down 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 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.

2 or 3 Stage Charging

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 differenti-

ate 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, VRLA or gel type batteries.

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.

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.

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.
