Frequently Asked Questions - 22846 Trix

How to configure the DCC address of my Trix 22846 locomotive?

To configure the DCC address, use CV 1 for a short address (1-127) or CV 17 and 18 for a long address (1-10239). Enable the long address by setting bit 5 of CV 29 to 1. By default, the factory address is 03.

My locomotive does not respond in digital mode, what to do?

First check the power supply (digital max 22 V AC). Make sure the protocol used is supported (mfx, DCC or MM). You can deactivate unused protocols via CV 50. Reset to factory settings with CV 8 = 8 if necessary.

How to activate or deactivate sound effects?

Sound effects are controlled by function keys F1 to F23. For example, F2 activates the whistle, F4 the brake squeal. Refer to the function table in the manual. Function mapping can be customized via the command station.

Can I use my locomotive on analog track?

Yes, the decoder automatically detects analog voltage (DC). All functions configured for analog mode (via CV 13 and 14) are active. However, advanced functions require digital mode.

How to adjust acceleration and braking delay?

Modify CV 3 for acceleration delay and CV 4 for braking delay. Values range from 0 to 255 (higher values mean longer delay). The factory value is 22 for both.

Why do the directional lights not reverse automatically?

The lights normally reverse according to direction of travel. Check that function F0 is activated. In digital mode, ensure the function mapping is correct. If the problem persists, check CV 29 bit 0 (direction of travel inversion).

How to reset all factory settings?

Program CV 8 with value 8. This resets all parameters (CVs) to factory values, including the DCC address 03 and MM 44.

How to stop the brake squeal sound?

Brake squeal is activated by function F4. Deactivate F4 to stop this sound. If you want to disable it permanently, modify the function mapping via your command station.

Can I run the locomotive under overhead wires?

No, the manual states that the locomotive cannot be operated under overhead wires. Use only on tracks without overhead wires.

Where can I find spare parts for my Trix 22846 locomotive?

Contact your specialized Trix dealer or Märklin customer service. The manual lists available spare parts. Also check www.maerklin.com for more information.

Spare Parts 30

• This locomotive is only to be used with the operating system it is designed for.
• Analog max. 15 volts DC, digital max. 22 volts AC.
• This locomotive must never be supplied with power from more than one power pack.
• Please make note of the safety notes in the instructions for your operating system.
• The feeder track must be equipped to prevent interference with radio and television reception, when the locomotive is to be run in conventional operation. The E611 655 interference suppression set is to be used for this purpose. The interference suppression set is not suitable for digital operation.
• WARNING! Sharp edges and points required for operation.
• Do not expose the model to direct sunlight, extreme changes in temperature, or high humidity.
• The LEDs in this item correspond to Laser Class 1 according to Standard EN 60825-1.

Important Notes

• The operating instructions and the packaging are a component part of the product and must therefore be kept as well as transferred along with the product to others.
• Please see your authorized Trix dealer for repairs or spare parts.
• The warranty card included with this product specifies the warranty conditions.

• Disposing: www.maerklin.com/en/imprint.html

• The full range of functions is only available under DCC and mfx.

• Built-in headlights that change over with the direction of travel. They can be turned on and off in digital operation.
  • Minimum radius for operation is 360 mm/14-3/16".
• The locomotive cannot be switched to operation from catenary.

This decoder can also be operated on analog layouts or areas of track that are analog. The decoder recognizes alternating current (DC) and automatically adapts to the analog track voltage. All functions that were set under mfx or DCC for analog operation are active (see Digital Operation).

Digital Operation

The decoders are multi-protocol decoders. These decoders can be used under the following digital protocols: mfx, DCC or MM.

Address set at the factory: DCC 03 / MM 44

The digital protocol with the most possibilities is the highest order digital protocol. The sequence of digital protocols in descending order is:

Priority 1: mfx

Priority 2: DCC

Priority 3: MM

Note: If two or more digital protocols are recognized in the track, the decoder automatically takes on the highest value digital protocol. For example, if mfx & DCC are recognized, the mfx digital protocol is taken on by the decoder. Individual protocols can be deactivated with Parameter CV 50.

Note: Please note that not all functions are possible in all digital protocols. Several settings for functions, which are supposed to be active in analog operation, can be done under mfx and DCC.

Notes on digital operation

• The operating instructions for your central unit will give you exact procedures for setting the different parameters.
• The setting done at the factory does not permit operation with opposite polarity DC power in the braking block. If you want this characteristic, you must do without conventional DC power operation (CV 29/Bit 2 = 0).

mfx Protocol

Addresses

• No address is required; each decoder is given a one-time, unique identifier (UID).
• The decoder automatically registers itself on a Central Station or a Mobile Station with its UID.
  • Name set at the factory: 421 378-1 SBBC

Programming

• The characteristics can be programmed using the graphic screen on the Central Station or also partially with the Mobile Station.
• All of the Configuration Variables (CV) can be read and programmed repeatedly.
• The programming can be done either on the main track or the programming track.
• The default settings (factory settings) can be produced repeatedly.
• Function mapping: Functions can be assigned to any of the function buttons with the help of the 60212 Central Station (with limitations) and with the 60213/60214/60215/60216/60226 Central Station (See help section in the Central Station).

DCC Protocol

Addresses

• Possible addresses: short, long, and m.u. address
- Address range:

1 - 127 (short address, m.u. address)

1 - 10239 (long address)

• Every address can be programmed manually.
• A short or a long address is selected using the CVs.
• A multiple unit address that is being used deactivates the standard address.

Programming

• The characteristics can be changed repeatedly using the Configuration Variables (CV).
• The CV numbers and the CV values are entered directly.
• The CVs can be read and programmed repeatedly. (Programming is done on the programming track.)
• The CVs can be programmed, as you desire. PoM (Programming on the layout track) is only possible with those CVs marked in the CV table. PoM must be supported by your central controller (see the instructions for your controller).
• The default settings (factory settings) can be produced repeatedly.
  • 14 or 28/126 speed levels can be set.
• All of the functions can be controlled according to the function mapping (see CV description).
• See the CV description for the DCC protocol for additional information.

We recommend that in general programming should be done on the programming track.

Logic Functions

Acceleration / Braking Delay

• The acceleration and braking times can be set separately from each other.
• The logical function shut off for ABV (Acceleration / Braking Delay) can be assigned to any function button by means of function mapping.
