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.

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 maximum current and
the charging light will be on. After a period of time, which may be minutes to hours, the
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 to the batteries 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!

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.
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

batteries 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 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, 36.3 or 54.4 VDC,
which is generally 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.

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.
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.

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.
To change the position of the jumper, rst turn the unit off and disconnect the unit from both
the power and batteries. Next, turn the unit on for 30 seconds to discharge the capacitors,
then turn it off again. Remove the eight screws holding on the cover. Turn the unit upside
down, remove the cover and locate J22. It will be next to the relay as is shown in the above
diagram. Simply move the jumper to the desired position as is shown in the above diagram.
Replace the cover and re-install the eight screws. Reconnect the unit to the power and
batteries.
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 instructions of the temperature sensor, please see the section entitled
Remote Battery Temperature Sensor Installation.
