Cleaning
This model can be cleaned externally
using a mild detergent and gentle
stream of water. Do not immerse this
model.
Replacing the light bulbs
Front and rear lanterns:
These bulbs are mounted on circuit
boards at each end of the model (Fig.
4). To replace these bulbs, you must
remove the body of the model from
the chassis:
- Remove the eight vertical screws
on the bottom of the chassis.
- Remove the body of the model.
- Remove the appropriate circuit
board.
- Remove and replace the bulb.
- Reassemble.
Cab light: Using tweezers, remove
and replace the bulb.
Replacing the traction tire
- Remove the two screws in front of
and behind the gearbox with the
traction tire.
- Carefully pull out the gearbox until
you can reach the traction tire.
- Use a small, straight-blade screw-
driver to pry the old traction tire out
of the wheel groove.
- Use a small, straight-blade screw-
driver to gently pry the new traction
tire into the wheel groove.
- Make sure that the traction tire is
seated properly in the wheel
groove.
- Reassemble.

USERS
MTS Onboard Decoder
Programming functions
You can program numerous func-
tions of the onboard decoder to suit
your requirements. If you want to do
this, program the "function values"
in "registers" (CVs) using a PC and
the 55045 MTS PC Decoder
Programming Module. You can also
program the function values using a
55015 Universal Remote.
Hints:
- For normal operation, it is not nec-
essary to change the function val-
ues.
- If programming results in unsatis-
factory operation, you can repro-
gram the factory pre-set values of
most important CVs: Program reg-
ister CV55 to function value 55.
This also reprograms the loco ad-
dress to the factory pre-set value.
To reprogram the factory pre-set
function values with the 55015 (dis-
plays shows "P --") input 6, 5, and 5
and press the right arrow button. The
display shows "P --" again: Input 5,
5, and 5 and press the right arrow
button again.
You can program the following registers:
Register Function
CV1 Loco address
CV2 Starting voltage
voltage for speed setting 1 - if loco starts only at a higher
speed setting, increase value.
CV3 Acceleration (1 = fast, 255 = slow)
CV4 Braking (1 = fast, 255 = slow)
Hint: When programming with the 55015 Universal Remote, the following CVs are pro-
grammed by input of the number of the desired CV in CV6 and then input of the desired func-
tion value in CV5 (see example below).
CV5 Max. voltage
Voltage for highest speed step - if a lower top speed is
desired, decrease value.
CV5 after input of CV6
function value for CV to be programmed
CV6 CV to be programmed
CV29 Configuration
Normal direction:
4 = Analog and digital, factory-programmed speed steps
0 = Digital only, factory-programmed speed steps
20 = Analog and digital, user-programmed speed steps
16 = Digital only, user-programmed speed steps
Reversed direction:
5 = Analog and digital, factory-programmed speed steps
1 = Digital only, factory-programmed speed steps
21 = Analog and digital, user-programmed speed steps
17 = Digital only, user-programmed speed steps
With "Analog and digital:"
- Loco can operate on analog and digital layouts
With "Digital Only:"
- Normal operation on digital layouts.
- Operation on analog layouts not possible.
CV54 Hand-off function and "Back-EMF"
0 = hand-off function off, Back-EMF off
1 = hand-off function on, Back-EMF off
2 = hand-off function off, Back-EMF on
3 = hand-off function on, Back-EMF on
Hand-off function on: When operating with 55015, you can
adjust direction and speed for two seconds after selecting a
moving loco without causing the loco to stop.
CV55 Reset of most programmed CVs
55 = most important CVs are reset to the factory pre-set
values
CV60 Back-EMF: Max. adjustment factor (0: small, 255: large)
Specifies the max. increase or decrease of voltage applied
during each time interval (programmed in CV61)
Attention! The factory pre-set values of CV60 and CV61 are
optimized for LGB motors.
CV61 Back-EMF: Adjustment frequency (0: often, 255: seldom)
Specifies how often per second the motor voltage is adjusted
- accordingly, the loco will react to curves and grades
immediately or with a short delay
