WARNING: The power supply or battery used to power your LM-3S-G must
have short circuit protection and the short circuit protection should not exceed
12 amps.
WARNING: Maximum voltage is 24 Volts. Only power your LM-3S-G module
with a Ring Engineering Inc. RailPro Power Supply designed for the LM-3S-G
or a DCC power supply that only has the signal that is described in NMRA DCC
standards S-9.1 and S-9.2. You may use a proper battery to power your LM-
3S-G.
WARNING: If this module is wired incorrectly, or the maximum allowed voltage
is exceeded, it is possible that enough heat can be generated to ignite
flammable material, causing a fire. The use of improper resistors for LED or
low voltage lights is one possible source of this danger.

Warnings about Battery Power
High power batteries can explode and catch fire. Lithium batteries (i.e. LiPo) can
catch fire if they are shorted or punctured.
If you discharged lithium batteries even one time below its critical voltage it can
be permanently damaged and catch on fire when used.
If your discharge or charge current is higher than the battery is rated for it can
explode or catch fire.
The smoke from a lithium battery fire can be dangerous to your health.
This is not intended to be a complete list of dangers related to using batteries, so
if you are going to use batteries, you need to be aware of all the risks involved.
Maximum voltage for a lithium battery pack is 5s (18.5 volts - five 3.7V cells in
series).

Installation
When done correctly we are confident that RailPro can be installed in most G
and O scale locomotives and it will perform as expected. However, installing a
RailPro module in your locomotive is done at your own risk. Ring Engineering will not
be responsible for any incidental or consequential damages to your equipment or
property.
Step 1 – Remove unneeded circuit boards.
You can remove any circuit board(s) from your locomotive leaving only the motor(s),
lights, and speaker(s). The LM-3S-G has all the electronics necessary to run your
locomotive motor(s), lights, speaker(s) and no other circuit boards are necessary.
Locomotives may have light boards that have only the lights and dropping resistors on
them. In most cases it is wise to keep such light boards with dropping resistors in
place.
Some manufacturers have a special circuit board for the smoke unit and that
circuit board needs to be kept in the locomotive and properly connected. Connecting
a LM-3S-G output directly to a smoke unit that needs a circuit board to protect the
smoke unit from burning out, can damage the smoke unit and may become a fire
hazard.
Step 2 – Mount the LM 3S G in your locomotive.
IMPORTANT: Module must be mounted level with the RailPro logo pointing straight
up in order for it to have proper heat dissipation. You need to be sure there is 1/8" of
space on the four sides of module and a 1/2 inch of space above the module for
proper cooling. The module can be attached with double face tape to the bottom of
the LM-3S-G module.
TIP: If the auto set for the Motor ull Load current is set up to less than 1500mA you
can mount the module in any orientation.

TIP: Mounting the module higher in the locomotive and away from metal parts may
extend its radio range.
Step 3 – Connect the motor(s) per the included wiring diagram.
See page 7 for wiring diagram.
IMPORTANT: Only attach wires to the screw terminals that are between 18 and 26
AWG.
IMPORTANT: You should solder the ends of any stranded wires to prevent a strand
from getting into an adjacent screw terminal and causing a short.
Step 4 – Connect the lights per the included wiring diagram.
IMPORTANT: If your light bulbs are LEDs or low voltage bulbs you will need to be
sure to add the dropping resistors as shown in the wiring diagram for low voltage
lights.
If your lights need resistors and you do not include them, you can damage your
lights.
IMPORTANT: It is best to connect any lights to the five volt source. Many G scale
locomotives have light boards that are designed for five volts. Ask your locomotive
manufacturer what voltage is required for their lights.
TIP: You do not need the resistors if your lights are five volt lights.
TIP: You can remove any unused wires from the nine pin connector by lifting the
keeper on the connector and sliding the wire out of the connector. It is wise to keep
the wires and if you need them later you can slide the wires back into the connector.
Step 5 – Connect the speaker(s) per the included wiring diagram.
An 8 ohm speaker that is rated for less than 7 watts or a 4 ohm speaker that is
rated for less than 13 watts may be damaged by the LM-3S-G and could become a
fire hazard.
Step 6 – Connect the power source (Track Power or Battery Power)
per the included wiring diagram.
Never connect track pickup and battery power at the same time.
You may use a double pole double throw switch that disconnects the battery power
before connecting the track power and vice versa such that when the switch is in one
position the LM-3S-G can be battery powered and when the switch is in the other
position the LM-3S-G can be track powered.
The voltage of the power source must be less than your locomotive motor rating.
If battery power is used, no more than 5 series connected (5S - 18.5volts) LiPo
batteries should be used. No mare than 16 series connected NiMH batteries should
be used (19.2 Volts).
Step 7 – Double check your wiring and be sure every thing is
connected properly.
Be sure all the wires are connected to the proper terminals and there are no short
circuits.
If this module is wired incorrectly it can cause a fire and can be damaged.

Improperly wired module is not covered under the warranty.
IMPORTANT: Check carefully between the screw terminals to be sure all strands of
stranded wires are in the correct terminal and no stray strands are accidentally in the
adjacent screw terminal. That will cause a short circuit and can damage the module.
Step 8 – Power up the module.
Step 9 – Press 'Find Product' on your RailPro controller.
Step 10 – Go to the locomotive adjustments and in the Name field
enter the locomotive road number.
rom the “Control Locomotive” page you can press the “Adjust Setups” button (round
button on the left side of the screen) to view the “Locomotive Setup” page. As with
most RailPro products you can give this product a name and a password from this
screen.
TIP: Notice the name we gave the locomotive on the page above is 9523 UP.
Although you can name your locomotive anything, it is wise to give them good names.
You should put the road number first and any letters after the numbers so they sort
correctly.
TIP: You can leave the password field blank if you do not need password protection.
A password can prevent other RailPro controllers from controlling your products.

Step 11 – Go to the adjustments and use Next Page button until you
see 'Motor Full Load Current'.
This is the only setting you should set before using your RailPro equipped locomotive.
By setting the motor full load current, you setup the locomotive module to: 1) Allow
multiple locomotives to run well when linked together and 2) Allow the module to
detect and report motor faults if necessary.
1. On your RailPro controller's Main Page press the “Locomotives” button.
Touch the picture of the locomotive to take control of the locomotive.
2. Press the "Adjustments" button (round button on the left side of the screen).
Then press “Next Page” button until you see the “Motor ull Load Current”
button. Then press the “Motor ull Load Current” Button then press the
“Yes” button when it asks to “Use auto set?”
3. Press the “Start Test” button and wait until the test finishes.
4. Press “Exit Page” button and press the “Save” button.
During the test your locomotive will run at full speed and a G locomotive can pull
with a lot of force so be prepared to hold on tight.
During the test your locomotive may run at full speed backward. So be prepared
for it to go in either direction. If your locomotive runs backward, go into the
adjustments and change the motor direction and run the test again.
If the 'Motor ull Load Current' sets to above 1500mA the module must be
oriented level with the RailPro logo on the module label pointing straight up, and the
specified space around the module must be maintained to promote proper heat
dissipation. See Step 2 for mounting details.
IMPORTANT: If you are using battery power, you need to be sure the battery is
always at the same voltage (same amount of charge) before setting the Motor ull
Load Current. You can check your battery voltage on the handheld controller
locomotive information page. Recommended battery voltage before setting Motor
ull Load Current is 12.7 volts for 4 series LiPo and 16.0 volts for 5 series LiPo.
Step 12 – You can now use your RailPro locomotive.
TIP: You can customize the locomotive module settings if you want to. You can load
a picture of your locomotive, change sounds, light effects, change the user button
setup, and much more. Please see the RailPro Assistant user manual (online only
www.ringengineering.com/RailProAssistantSoftware.htm) and the RailPro handheld
controller user manual for setup details. www.ringengineering.com/HC-2.htm
