INSTALLATION: This decoder board completely replaces the PC Board in the Atlas
GenSet Loco. Slowly remove the body shell from the chassis of the loco. Don't break
wires when you remove the body shell. We recomend using a dab of hot glue to secure the
headlight wires close to the headlight location inside the long hood of the body shell, to
avoid them breaking off. Use a 1" to 2" thin wire to connect ("T" connection) the two black
wires from the headlights.Tape the joint to avoid short circuit. This thin wire will be
connected to the tab marked "headlight com". Remove the original board with two Atlas
ditch light boards. Remove the weight from the rear part of the chassis. Remove two
capacitorshidden under the weight. They will not be used. The speaker supplied with your
decoder fits snugly in place where you removed the two capacitors. We recomend using a
small bead of glue to fully secure the speaker to it's location. Before installing the ditch
light boards please use clear tape to completely wrap both front and rear ditch light board
holders/slots to prevent the LEDs from touching the chassis, and shorting out. The ditch
light boards are already soldered to the decoder for your conveniance. Be very careful with
these wires as they are very fragile. The 4 ditch lights are tiny SMD led's. Do not put force
on them during install or when removing the ditch light boards. You may need to remove
some of the tape from the board to ease the fit. However, you must make sure the rear
board be covered with tape, or insulated from the frame. Due to Atlas changing the chassis
after first run of production they have two versions of chassis. You may have problem of
fiting the light board . You can compare the light board to the original one. If our light
boards are shorter than yours, you have to cut the light board in the middle. Don't not cut
the jump wire which links the two light together. Using clear tape wrap the pcb. Using the
supplied wiring diagram, attach the four pickup, two motor and three headlight wires to the
decoder board and secure using the plastic clips or by
soldering the wires to the tabs on the decoder. The black
motor wire may need to be extended. Use all the wire channels
in the chassis to route the wires going to the decoder and use
scotch tape in these locations to keep the wires from moving.

OPERATION
The decoder has a default address #3. Select address #3 on your DCC system. Release service
brake (F5). You will hear the brake release sound when you turn off F5. Move up the throttle and the
loco should start to moveThe decoder has start up and shut down features. If the loco was previously
shut down you have to start up the engine. Press any function key to start up the engine before
operating the loco. To shut down the engine you must bring the loco to idle and then press F8 three
times. This decoder is default to manual notch setting (CV122=3). F9 will notch up and F8 will notch
down. If you want automatic notching enabled set CV 122 = 0. It has three independent diesel genset
prime mover sounds. The second engine will turn on at notch 4 and turn off below notch 4. The third
will turn on at notch 6 and and turn off below notch 6. This decoder also mimics the real GenSet, and
if left idling for a long period of time will shut down and restart automatically at specific intervals to
conserve fuel. Shutting off the sound in CV49 will not disable the horn. The decoder has two types of
diesel prime movers. You can use F12 or CV 123 to select the desired prime mover sound. You can
use F19 to select 34 different horn sounds and use F18 to select 8 different bell sounds. With MRC
Prodigy Advance2 DCC which has 28 functions, you can easily setup and access all the decoder's
functions. If not, you may not be able to access all the features of the decoder. And you have to use
the CV program to setup the decoder.
SERVICE BRAKING
To apply service brake set throttle to zero and press F5. The loco will slow down fast and you will
hear the brake squeal. You can pump the brake by turning F5 on and off to stop the loco at desired
location. The brake rate is proportional to deceleration rate that you program in CV4. If you forget to
turn off F5 and move the throttle up. The loco will move. However, when you release the throttle the
service brake will apply again. The service brake can only operate when throttle is at 0. If you don't
hear the brake sound program CV115 with a value of 2.
BACK EMF LOAD CONTROL (PID CONTROLLER)
This decoder is equipped with adjustable back EMF load control feature. It is a closed loop speed
control. With back EMF load control the locomotive will maintain its speed regardless of pulling up hill
or driving down hill. You may program the back EMF load control intensity, CV124, to a lower value to
get less back EMF load control. This will enable the locomotive to slow down during uphill travel like
real locomotive. The PID controller contains three components: proportional gain (CV113); the
integral gain (CV114); and derivative gain (fixed). Designing (tuning) a PID controller is a kind of
"rocket science". So optimized these gains at the factory but still give the customer final adjustments.
We recommend that you do not change these settings. Too much gain may cause the motor to
oscilate (becomeunstable). Too little gain may cause slow response. Additional knowledge of PID
feedback control is required before attempting to adjust CV113 and CV114. If CV113 and CV114 are
programmed incorrectly, the locomotive will not run smothly. If this happens just program CV124 to 0.
HAED LIGHT EFFECT CV117
The decoder has 17 different lights
effects. CV 117 controls both front
and rear headlight effect.
