Gold Maxi Locomotive decoder
The DIGITAL plus GOLD MAXI locomotive decoder is suitable for all DC locomotives with
continuous current draw of 3.0 Amp. or less. The characteristics of the decoder are:
Super smooth and silent high frequency back-emf motor control.
Supports the industry proposed enhancements to the NMRA DCC Bidirectional data
communication RPs
USP with optional power module for operation on dirty track
Asymmetrical DCC support including directional stopping
Adjustable precision stopping control
Low speed gear for switching operations
Selectable for operation with 14/27, or 28/128 speed steps.
Operation on conventional DC layouts is possible or can be disabled.
Motor output = 3A continuous, 5A max, > 10A stall.
Motor and function outputs protected
Eight function outputs rated at 1A each with advanced function mapping
Directional or independent lighting with dimming and special effects.
Support for Advanced Consist Control and Extended Addressing

  • Page 2: Important Safety Instructions

    Important safety instructions Digital plus locomotive decoders are designed to be used only with Lenz Digital plus or other standard NMRA Digital Command Control system. For best performance we recommend systems with an NMRA-conformance seal. If in doubt, ask the system supplier.
  • Page 3 Gold Maxi Locomotive decoder The current-carrying capacities noted in the technical data above may not be exceeded. Before installing a Digital plus decoder, check the locomotive in normal DC operation to ensure that it works correctly before modifying the locomotive. Replace worn wheel contacts, motor brushes and blown bulbs.
  • Page 4: Testing The Installation

    Gold Maxi Locomotive decoder • Function outputs C-H are connected to F1 to F6 If a connection between the bulbs and chassis exists, the connection of the front lighting is completed. If the bulbs are not electrically connected to the locomotive chassis (we call this 'potential-free'), connect the other pole of the bulbs to the connection U+ of the GOLD maxi (which of the U+ connections is irrelevant).

    Gold Maxi Locomotive decoder For more detailed information please refer to the "Decoder operating manual" which is available at your hobby shop or can be downloaded from the Lenz Elektronik GmbH website: www.lenz-elektronik.de or www.lenz.com Protection equipment The decoder is protected against overloading, short circuits and overheating. In case of a fault, the corresponding bit is set in CV30 which will state the type of fault which has occured.
  • Page 6 Gold Maxi Locomotive decoder defined braking distance. This braking distance does not depend on the speed of the locomotive/train. Setting the constant braking distance: The braking distance is defined by the value set in CV52. Since the motors and gear ratios of locomotives vary, the braking distance differs from locomotive to locomotive even if the same value is set in CV52.
  • Page 7 Gold Maxi Locomotive decoder constant braking distance is disabled. The shunting speed is enabled as long as the function is active. ABC = simple signal stop and slow approach You can carry out a particularly simple signal stop using the ABC braking module. Depending on the signal position, this module creates an asymmetric track voltage in the braking section in front of the signal.
  • Page 8 (PoM)" or "Programming on the programming track". When using ® Digital plus by Lenz systems, you can change CVs 1 to 999 with PoM, while "Programming on the programming track" is currently used for CVs 1 to 256. CVs 897 to 1024 have been defined for the S.U.S.I.
  • Page 9 Gold Maxi Locomotive decoder The function sequence is as follows: The target (number of the CV) is entered in the indicator CV126, and the value that is to be transported to the target is entered in the transport device CV127. If you only wish to read out the target CV, the transport device CV127 is read out after the target is entered in CV126.
  • Page 10 Gold Maxi Locomotive decoder Signal stop and push-pull control with an external reed contact The GOLD Maxi has a connection for an external reed contact. The reed contact is installed at the bottom of the locomotive. You can let your locomotive stop in front of a signal or operate in push-pull operation with the help of a magnet installed in the track.

    Gold Maxi Locomotive decoder service mode programming (such as Set-90 or Set-100). Please note that not all systems support the programming of all CVs. You can also alter the content of CVs both through "Programming in operational mode (PoM)" (except for CV1, CV17 and CV18) or "Programming on the programming track".
  • Page 12 Meaning default setting 1-127 Basic locomotive address. This number is used to ® call up locomotives in the Digital plus by Lenz system. The use of range 1-99 is recommended for ® operation with Digital plus by Lenz devices. When writing this CV, CV19 (multiple traction address) is automatically deleted in the decoder and Bit 6 (use of extended address) is deleted in CV29.
