DIESEL SOUNDS FUNCTION CHART
Note2: when CV122=3 (manual notch up/down, F8 will notch down and F9 will
notch up.
Bell, Dynamic Brake and Rail Wheel Clack cannot play at the same time. If you
activate the Bell sound [F1], while either the Dynamic Brake or Rail Wheel Clack
sounds are in use, the Bell sound will override the other 2 sounds. Rail Wheel
Clack cannot play while the loco is in idle. When you turn off Dynamic brake and
Rail Wheel Clack sound there will be one second delay.
INSTALLATION
It is easy to install this decoder into a Kato GE P42 or EMD E8/9 diesel locomotive.
Remove the original circuit board by very carefully removing the plastic clip (fig 3),
and sliding the circuit board out. Remove the copper contact strips. The 0001645
sound decoder is installed in the same location. However, you will have to use a
hobby knife to trim some plastic “bumps” before installing the decoder. (See fig 1 &
2) You must apply tape on the chassis (as shown) to prevent it from touching the
decoder. Make sure the four spring contacts (fig 3) properly sit on the wheel
pickups. Spring contacts under decoder board should be angled approx 20 deg. to
provide correct contact tension. After installing the decoder apply tape as shown to
hold the PCB straight.
How to install 0001645 decoder:
Carefully trim 14 raised plastic areas (shown) so they are level. (see fig 1 & fig 2)
MAKING A TEST TRACK
Before you begin decoder installation, we strongly recommend building a test
track with a 27 ohm resistor to limit current. Only test your installed decoder on
the test track. The test track may prevent damage from an incorrectly installed
decoder.
Note: The program track is NOT a test track. The program track does not use a
current limiting resistor. So it can’t protect an incorrectly installed decoder.
TESTING
All MRC decoders have been factory programmed with address #3, 28/128
speed steps and maximum top voltage.
Never run the installed decoder on
your layout without first successfully running on test track.
Otherwise,
you may damage the decoder if it is not wired correctly or if you have not
properly isolated the motor, chassis and lights.
To test, place the loco on the test track. Select the “Run” mode of your DCC
system and select or acquire address #3. Move up the throttle and the loco
should move forward. Push the light button [F0] and the front headlight should
come on. Change the direction of the loco and the loco should change direction
and the rear headlight (if equipped) should come on. The loco cannot reach full
speed, due to the resistor. If all above occurs, you passed the test. Congratula-
tions!
Do not run the loco for an extended period of time on the test track or
the resistor will overheat.
If your installed decoder does not pass the test, find the problem, correct it and
test it again.
DCC OPERATION
This decoder has start up and shut down feature. You must 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 3 times.
This decoder can also be used in an Electric Type Traction Loco such as Trolley
or GG-1 by turning off diesel sounds. To turn off the diesel prime mover sounds,
program CV #122 with value 0.
There are many more program features available with this decoder. Please refer
to the CV Chart to explore other features of the decoder.
DC OPERATION
The 0001645 decoder provides synchronized diesel rumble sound with DC
operation. Bells, horns, etc., cannot be accessed. Use of the MRC BlackBox will
enable the full range of sounds on a DC system.
CAUTION:
Wrap the chassis with tape (as shown in figure 2) to prevent the electrical
contacts from touching the chassis. Otherwise, the decoder will be destroyed if
the decoder contacts touch any unwrapped part of the chassis.
Carefully seat the sound decoder as shown in Fig 3. Reinstall plastic “clip” securing
motor contact springs to the top of the decoder board (fig. 2 & 3)
