1. INTRODUCTION
The ATLAS is a modular switch mode (high frequency) battery charger / power supply platform designed for
railroad signal and communication, as well as other industrial stationary / reserve power applications.
ATLAS is convection cooled with no fans or other moving parts and designed to provide maximum reliability in
industrial environments. The modular architecture provides redundancy and maximizes uptime, and the
system controller combines the simplicity of rotary switches to adjust the float voltage with sophisticated
communication, alarming, and logging options. The universal AC input enables the charger to be used with a
wide range of AC voltages and frequencies, and the system features high energy efficiency and power factor.
As is illustrated in Figure 1-1, an ATLAS system includes a chassis. The chassis has a User Interface Module
(UIM) that serves as the system controller and user interface and an access panel for the AC input and DC
output terminals. Chassis are available with four (4) or two (2) slots for Intelligent Power Modules (iPMs).
Figure 1-1: ATLAS System Components
Both 12 Vdc, 400W, 20A and 24 Vdc, 400W, 10A iPMs are available. Figure 1-2 shows the corresponding
maximum system DC output current for a given number of iPMs. An ATLAS system can be set to charge
batteries within a voltage range of 1.00 to 20.00 volts (12 Vdc nominal system) or 10.00 to 40.00 volts (24 Vdc
nominal system) for nickel-cadmium (Ni-Cd), valve regulated lead-acid (VRLA), and flooded/vented lead-acid
batteries. The values shown throughout this manual in the instruction tables and figures are for generic use
and may be different from the actual values programmed in your unit. Customized settings are available,
contact a Lester Electrical service agent at 1-402-477-8988.

2. THEORY OF OPERATION
The charger has an "IE" profile which is (1) a constant-current bulk/start phase followed by (b) a constant-
voltage float phase. When the charger is first started, if the battery pack voltage is below the charger float
voltage value, it will output a constant current in the bulk phase. The constant current value is controlled by
the “Max DC Output Current” setting available via the charger web server using the Ethernet port.
When the battery pack nears the charger float voltage value, the charger will transition from the bulk phase
into the float phase. The output current will decrease in order to maintain a constant float voltage. The
charger float voltage value is controlled by either (1) the “NUMBER OF CELLS” and “VOLTS PER CELL”
rotary switches on the UIM or (2), if the “NUMBER OF CELLS” rotary switches are set to “00”, the “Number of
Cells” and “Float Voltage Per Cell” settings available via the charger web server control the float voltage value
(see Section 11.3 for valid ranges). The constant float voltage will be maintained indefinitely to keep the
battery pack fully charged.
The charger web server, which is detailed in Section 11, includes other settings, such as battery temperature
compensation, that can be adjusted per the requirements of the battery pack and overall system.
3. RECEIVING AND INSTALLING THE CHARGER
WARNING: NEVER PLACE ANYTHING ON TOP OF THE CHARGER WHILE OPERATING. DAMAGE
TO THE CHARGER OR BATTERIES COULD OCCUR.
WARNING: THE CHARGER MUST BE SET UP FOR THE PROPER USER SPECIFICATIONS BEFORE
STARTING THE INITIAL CHARGE.
WARNING: CHARGERS CAN IGNITE FLAMMABLE MATERIALS AND VAPORS. DO NOT USE NEAR
FUELS, GRAIN DUST, SOLVENTS, THINNERS, OR OTHER FLAMMABLES.
WARNING: REPLACE WORN, DAMAGED, OR CUT ELECTRICAL CORDS AND CONNECTORS
IMMEDIATELY.
Proper installation of the charger is important in order to achieve good charger performance and to prevent
damage to the charger and batteries.
When a charger is received, a check for possible in-transit damage should be made. If any damage is found,
it should be reported as a claim to the carrier.
The dimensions for the charger and mounting brackets are shown in Figure 3-1 (4-slot chassis) and Figure 3-
2 (2-slot chassis).
To permit free air flow for convention cooling, allow 2 inches (2") minimum between the charger sides and
other equipment and 4 inches (4") minimum on top of the charger. Do not mount the charger above other
heat generating equipment.
The charger can be mounted on a shelf, countertop, floor, wall, or rack. The charger case includes four (4)
cushioned feet that are designed to prevent marring of mounting surface and to absorb vibration. The
charger includes adjustable mounting brackets that provide highly flexible mounting options. See Figure 3-1
(4-slot chassis) or Figure 3-2 (2-slot chassis) for details.

ATLAS 7 of 44 User’s Manual
Wall or Shelf Mounting
The charger can be fastened to a wall for wall or shelf mounting, by attaching the mounting brackets to the
last two side mounting screw holes near the rear of the charger. Then, 1/4" bolts or lag screws can be
installed in each of the (4) key slots or by using the top and bottom 0.281 diameter round holes in the
mounting brackets (4 bolts total).
Rack Mounting
The 4-slot chassis can be mounted to a standard Electronic Industries Association (EIA) 19” (483mm) rack
system. The 2-slot can also be mounted to a standard EIA 19” rack system using an optional mounting
bracket. An industry standard 3/8" square hole rack, 12-24 UNC cage nuts, and 12-24 UNC rack screws are
recommended. A 12-24 screw should be installed through each of the 2 highest slots and 1 of the 2 lowest,
0.218" X 0.312" slots in both of the 2 mounting brackets (a total of 6 screws minimum). The 12-24 screws
should be tightened to 40 in--lb. If other sizes and/or types of fasteners are used, the quantity, location and
tightening torque should be designed as recommended by the manufacturer to be at least as strong as the
above recommendation. By adjusting the locations of the mounting brackets along the 1/2" spacing of screw
holes along the side of the charger, many different mounting configurations are possible, from flush mounted
to forward mounted.
The patterns of the mounting bracket rack mounting holes and slots are shown in Figure 3-1 (4-slot chassis).

4. AC INPUT
WARNING: FAILURE TO PROPERLY CONNECT THE AC VOLTAGE CONDUCTORS COULD CAUSE
SERIOUS DAMAGE TO THE CHARGER.
WARNING: DO NOT OPERATE THE CHARGER WITHOUT PROPER GROUNDING. IMPROPER
GROUNDING CAN RESULT IN THE RISK OF AN ELECTRIC SHOCK.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK OR FIRE, DISCONNECT AC POWER
FROM THE CHARGER BEFORE INSTALLING OR REMOVING UNIT.
WARNING: DO NOT TOUCH THE CHARGER'S TERMINALS OR AN ELECTRICAL SHOCK COULD
OCCUR. A VOLTAGE IS PRESENT ON THE DC TERMINALS EVEN AFTER THE AC IS DISCONNECTED
BECAUSE OF THE ENERGY STORED IN THE CAPACITORS.
The charger has an AC input rating of 100-240 volts, 50-200 hertz, single-phase. The charger has an AC
operating range of 90-264 volts, 45-205 hertz. Below 100 volts, the charger may reduce output power.
Use an appropriate size wire for the AC input. Quarter-inch (1/4") ring terminals are required for proper
connection to the AC input binding posts (A.A.R.) located on the front of the charger. Open the access door
cover on the front of the charger. Route the AC wires and/or conduit in accordance with the National
Electrical Code and all local codes and ordinances. Dress field installed Class 2 or Class 3 circuits at
least 1/4 inch (6.3 mm) away from power, light, or Class 1 circuits. Connect the AC input terminals on
the two right-most posts, as marked on the A.A.R. terminal board, inside of the access door. Connect the AC
ground to the terminal lug provided, as also marked on the inside of the access door. Close the access door
after tightening all of the binding post nuts.
5. DC OUTPUT
WARNING: DO NOT TOUCH THE CHARGER'S TERMINALS OR AN ELECTRICAL SHOCK COULD
OCCUR.
WARNING: BATTERIES GENERATE EXPLOSIVE GAS. CHARGE ONLY IN WELL VENTILATED
AREAS. TO PREVENT ARCING OR BURNING NEAR BATTERIES, DO NOT DISCONNECT THE DC
CHARGING CONNECTOR(S) FROM THE BATTERIES WHEN THE CHARGER IS OPERATING. IF THE
CHARGE CYCLE MUST BE INTERRUPTED, UNPLUG THE AC POWER CORD BEFORE
DISCONNECTING THE DC OUTPUT CONNECTOR(S) FROM THE BATTERIES. KEEP SPARKS, FLAME,
AND SMOKING MATERIALS AWAY FROM BATTERIES. TO REDUCE THE RISK OF FIRE, DO NOT USE
THE CHARGER NEAR FLAMMABLE MATERIALS OR VAPORS.
Use Table 5-1 to select the appropriate gauge and length DC output cable for your application. Maximum
wire gauge is 4 AWG to fit the openings for the DC wiring above the binding posts (A.A.R.). Dress field
installed Class 2 or Class 3 circuits at least 1/4 inch (6.3 mm) away from power, light, or Class 1
circuits.
Quarter-inch (1/4") ring terminals are required for proper connection to the DC output binding posts (A.A.R.)
located on the front of the charger. Open the access door cover on the front of the charger. Connect the DC
output terminals on the two left-most posts, with positive (+) on the left and negative (-) on the right, as
marked on the A.A.R. terminal board, inside of the access door. Check to make sure that the polarity of the
DC output wires are the same as those connected to the battery. The charger will not operate in a reversed
polarity condition. If the DC polarity is reversed, the main DC output fuse will protect the charger from internal
damage. Correct the reversed wires and replace the fuse. Close the access door after tightening all of the
binding post nuts.

6. BATTERY TEMPERATURE SENSOR
WARNING: IT IS IMPORTANT TO MOUNT THE TEMPERATURE SENSOR ON THE BATTERIES
FOR PROPER TEMPERATURE COMPENSATION. IF THIS CANNOT BE DONE, LOCATE THE SENSOR
AS LOW AS POSSIBLE IN THE BUNGALOW, ENCLOSURE, OR CABINET.
The external battery temperature sensor is an optional way of extending battery life by using temperature
compensation. One end of the temperature sensor cable has a three-pin plug that plugs into a receptacle
labeled “BATTERY TEMP SENSOR” on the UIM (see Figure 7-1). The other end of the cable has the
temperature sensor sealed in a terminal.
The terminal-type sensor should be attached to a negative (-) battery post near the center of the battery pack.
If the threaded stud is long enough above the battery jumper nut, attach the sensor with another nut. Torque
this nut to proper specifications. If the stud is too short, the nut holding the jumper wire will need to be
removed. Open or remove the load and charging circuits to the batteries. Remove the nut holding the jumper
and add the sensor, then torque the nut to the proper specifications. Then close or connect the load and
charging circuits back to the batteries.
Securely fasten the temperature sensor cable to protect the sensor from being torn from the battery.
Secure the sensor cable to a fixed object to ensure the sensor will not be pulled loose. Use a cable tie mount
on the battery or on the adjacent battery, if necessary.

7. USER INTERFACE MODULE (UIM)
7.1. User Interface Module (UIM)
Below are descriptions of the user interface items found on the UIM. Figure 7-1 identifies these user interface
items.
Number of Cells Rotary Switches
Used to manually set the number of battery cells. See Section 11.3 for valid ranges. Setting to “00” enables
control via the web server.
Volts Per Cell Rotary Switches
Used to manually set the float voltage per cell. See Section 11.3 for valid ranges. Not used if t he “NUMBER
OF CELLS” rotary switches are set to “00”, which enables float voltage control via the web server.
UIM Status LED
Green LED. See the UIM LEDs table for possible states.
Alarm LED
Red LED. See the UIM LEDs table for possible states.
AC Present LED
Blue LED that is on when AC power is present.
Confirm Local Presence Button and LED
Pressing the button enables setting/alarm changes to be saved via the web server for a set amount of time.
This ensures that the changes are being made locally and provides the highest level of possible security.
Alarm Relay Terminals
Form C, dry contacts. Configurable per alarm via the web server by selecting the K1 relay in the alarm
settings menu.
Relay Terminal Remote Wiring
The terminal strip has OPEN, COMMON, and CLOSED relay contacts for remote wiring. COMMON to
CLOSED has continuity when no alarms or faults for the K1 relay are active. To insert a 28 to 12 AWG wire
striped 5 to 6mm, use a small screw driver to push the white tab at the top upwards. Insert the wire and verify
good contact. The relay contacts are rated for 1A at 30Vdc or 0.5A at 120Vac.
Battery Temperature Sensor Connector
Can be connected to a battery temperature sensor in order to temperature compensate the charge profile.
Enabled/disabled, compensation value, min compensation limit, and max compensation limit configurable via
the web server. The reference temperature for compensation is 25ºC or 77ºF.
Ethernet Connector
Provides local or remote access to the internal charger web server via a standard Internet browser. The web
server is used to check the status of the charger (DC amps, AC volts, etc), control the charger (on/off, manual
equalize, etc), configure settings/alarms, and view/download the history log. NTP time synchronization and
SNMP alarming are also supported.
Remote DC Voltage Connector
Can be wired directly to the battery pack in order to measure the voltage without any DC cable drop.
Enabled/disabled via the web server. This option allows for a more accurate float voltage at higher current
levels.
The UIM is powered by both AC and DC power so as to remain powered on when AC power is lost. This
allows all alarms and the UIM to function as desired. Removal of both the AC and DC power and then return
of either power source will allow for the UIM LED's to do a power up sequence and reboot the UIM.

ATLAS 12 of 44 User’s Manual
Figure 7-1: User Interface Items on the UIM
7.2. Digital Meter
When the multi-function digital meter option is ordered, it is mounted on the front of the charger. The meter
displays both the charger output voltage and current. The top red number displays the output voltage, which
is measured internal to the charger. Because it is measured internal to the charger, it will differ from the
voltage measured at the battery pack due to the voltage drop of the cabling between the charger and battery
pack. It will also differ from the “Battery Voltage” displayed on the web server “Dashboard” for the same
reason. The bottom green number displays the output current of the charger, so depending on the
application, the battery pack and load may share this current. Figure 7-2 illustrates the digital meter.

with the internal charger web server via a direct local connection to a laptop computer accessed via a
standard Internet browser or a networked connection to a remote or local laptop or desktop computer, smart
phone, or tablet via a standard Internet browser. Enable JavaScript within the Internet browser you plan
to use per the browser instructions (JavaScript is typically enabled by default). The Internet browser
must also support HTML5, which all popular modern browsers do (Internet Explorer is not
recommended).
10.1. Direct Local Communication
The charger Ethernet port is auto crossover, auto MDI-X, so it can be directly connect to a local laptop
computer via either (1) a standard Ethernet cable or (2) a crossover Ethernet cable. See Section 10.3 for
Manual (Static) Mode configuration instructions for direct local communication. The charger can then be
accessed via a standard Internet browser.

10.2. Networked Remote or Local Communication
The charger Ethernet port can be connected to an Ethernet switch or router via a standard Ethernet cable in
order to add the charger to network. See Section 10.3 for Manual (Static) Mode configuration instructions for
networked communication. See Section 10.4 for Automatic (DHCP) Mode configuration instructions for
networked communication. Once the charger has been added to a network, it can be accessed via a remote
or local laptop computer, desktop computer, smart phone, or tablet via a standard Internet browser.
10.3. Manual (Static) Mode
The standard settings from the factory are “Manual (Static) Mode” with an “IP Address” of “10.10.10.210” and
a “Subnet Mask” of “255.255.255.0”. Your charger may have been factory-configured with alternate
settings. If this is the case, the charger may include a “Quick Start Guide” that lists these settings or
you may need to get these settings from your organization’s management.
Direct Local Communication
In order to establish direct local communication with a laptop computer, after connecting the charger Ethernet
port to the laptop Ethernet port, follow the steps below on a laptop computer. (The steps below are for
Windows 7. If you are using a different version of Windows or a different operating system, the steps will
vary).

10.6. Restoring the Factory-Default Ethernet Port Settings
If you are unable to communicate with a charger after changing the setttings within the “Ethernet Port” section
on the “Configuration >> Ethernet Settings” page, you can restore the factory-default “Ethernet Port”settings
by following the steps below
Remove AC and DC (battery) power from the charger.
Press and hold the “CONFIRM LOCAL PRESE NCE” button on charger UIM.
Re-apply AC and or DC (battery) power to the charger while continuing to hold the “CONFIRM
LOCAL PRESENCE” button until the charger completes booting up (UIM LED startup sequence has
finished.).
The “Ethernet Port” settings have now been restored to the factory -defaults.
Follow the steps in Section 10.3 again.
