INSTALLATION
For newer locomotives with a circuit board and wires, simply remove the old circuit
board and follow the diagram to install the decoder. Hook up the front headlight to
the tabs marked as FL and COM. Hook up the rear headlight to the tabs marked as
RL and COM. For accessory light, hook up to ACC and COM.
The motor terminals must be isolated from the wheel pickups. The four pickup
wires go to pickup tabs. The motor wires go to motor tabs.
You can use speaker sizes from 18mm to 28mm. The larger speaker the better
sound quality. For locos with tight space, an 18mm can be mounted on the decoder.
If your loco has space for a larger speaker we recommend you use 28mm
speaker for a better sound quality. Always use 8 Ohm speakers.
If you use 1.5V bulbs or LED’s, you should connect a 1k ohm resistor in series to
one of the leads to limit current. Use CV120 to adjust the brightness.
OPERATION
The decoder has a default address #3. Select address #3 on your DCC. Release
service brake
(F5) and dynamic brake (F6). You will hear the brake release
sound when you turn off F5. Move up the throttle and the loco should start to
move. If the loco does not move a speed 1 you can add more start voltage by
programming CV2 with a large number. You can program the acceleration
momentum CV3 and deceleration momentum CV4 to simulate the real train. The
decoder has start up and shut down features. If the loco was previously shut
down you have to start up the engine first. Press any function key to start up the
engine. To shut down the engine you must bring the loco to idle and then press
F8 three times.
This decoder has 4 different horns and bells. You can use F19 or program CV50
to select horn. And use F18 or program CV52 to select bell.
This decoder has an easy function exchange feature (re-mapping) that allows
certain pairs of functions to be swapped. For example, program CV37 with a
value of 1 will make F3 and F4 exchanged.
The decoder default is set to automatic notch mode. You can program CV122 to
3 for manual notch mode for realistic operation. In the manual notch mode the
notch level is not controlled by loco speed. It is controlled by F9 ( notch up) and
F8 ( notch down).
To make traction air compressor’s speed synchronize to the prime mover,
program CV121 with a value of 1. For a constant speed program CV121 with a
value of 0.
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.
DYNAMIC BRAKING
You can use dynamic brake F6 to reduce the speed. When you turn on F6 the
prime mover will notch down to 1 and you will hear the dynamic brake sound and
the loco will reduce its speed. When you release F6 the loco will speed up to the
orignal speed. If you forget to turn off F6 and move throttle up it will automatically
disable the dynamic brake and loco will start to move. To apply dynamic brake
again you have to cycle F6 off and on.
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 a 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 we 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 (become unstable).
Too little gain may cause a 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 smoothly. Program CV125 to
“1” will automatically restore the default PID controller settings. If you can not get the
PID controller work properly or you don’t know to tune it you should turn off the Back
EMF load control by program CV124 with a value of 0.
LIGHT EFFECT PROGRAMMING CHART FOR CV#117/118/119
The decoder has 17 different lights effects. CV 117 controls both front and rear
headlight effect. Use F0 to turn on or off the Headlights. CV118/CV119 control
ACC1/ACC2 light effect. Use F3 to turn on or off ACC1 and ACC2. For ditch light
operation you must program Cv118 and CV119 to the same ditch light type. In type
A the ditch lights will flash when F2 (horn) or F3 is on. In type B the ditch lights
will flash when F2 is on and stay on when F3 is on.
