Lenz in North America

Lenz is no longer active in the North American market.
Should you need service, the only authorized Lenz service centre for North America was TLA Custom Models. Accessory Pathways has assumed the role. They have the necessary software to upgrade Lenz equipment to V3.6.

Notes

  • Lenz was represented in the US by Tried and True Trains (Debbie Ames) from 1995 to 2012. As of 2012, TTT closed when the owners retired.
  • American Hobby Distributors then became the only authorized Lenz wholesaler in North America.
  • In 1997, TLA Custom Models became the warranty/service centre for Lenz products, as well as providing support for Canada. As of 2013, TLA Custom Models became the support centre for all of North America.
  • North American support is now through Accessory Pathways

Lenz and the Development of the NMRA's Digital Command Control

When the NMRA set up its Command Control Working Group, an early decision was to forego the analog technology available and focus exclusively on digital technology. The WG requested samples of command control systems using digital techniques from a number of manufacturers for the purpose of evaluating the technology. A few manufacturers did participate, notably Marklin, with its Digital= System. After evaluating the submissions, the WG determined that the signaling technique used by Digital= was suited to the application. The WG then built their DCC protocol around the concept of using a combined power + data signal.

After settling on a data transmission method and basic protocol, the NMRA contacted Lenz, the contractor who developed Marklin's command control system. The NMRA cannot, and will not, incorporate any patented technologies or commercial products into an NMRA standard. Lenz reviewed the draft standard and indicated that the proposed DCC protocol did not infringe on any patents held by Lenz.

In fact, the proposed DCC protocol was significantly different than that of the Lenz system, and added numerous features and provisions for future enhancements.

Lenz Digital Plus Product Line

The main product is Lenz's Digital Plus. This is their Digital Command Control system. Lenz also produces a variety of DCC components and accessories. Please note that not all Lenz command control products are NMRA Digital Command Control compliant products.

Lenz is an electronics company, whose involvement in command control began in the 1980s as a contractor to Marklin.

In the early 2000s, Lenz decided to rename their products from Set 01 and Set 02 to Set 90 and Set 100 respectively. The throttles are almost identical to the older ones in Set 01 and Set 02. The electronics and software are much improved in the Set 90 and Set 100. The product names are derived from the throttle included in the set, an LH90 or LH100. The separate command station and booster combination have been replaced by an integrated command station/booster. The new unit also included RailCom and improved response times on large layouts with multiple locomotives in operation.

Lenz warranties their Digital Command Control products for 6 years.

Lenz FAQs

Q: Why is my Lenz LH100 display flashing?

LH100

A steady or flashing display of LH100 usually indicates a broken wire in the cable. Another cause can be the EPROM in the throttle isn't seated or has corrosion on its pins.

In either case, the recommended action is to return the unit to a service center for repair.

Q: How do I clear the stack on Lenz command station LVZ100?

  1. Set address on your throttle to 000 in the same manner as any other address.
  2. Press "4" about 20-28 times.
  3. At this point, a short, delayed response occurs on the LH's display.
  4. Shut off system power and wait a minute or two (any residual power can dissipate)
  5. Turn system on. The stack should have been purged and reset the command station to factory default.

If you have a Rampmeter in the circuit, after step three power to track and the display will go off for a second or two.

Any decoder address entered with an LH unit will automatically be loaded into the system stack.

Q: Why is the Lenz LH90 showing ERR 03 when trying to consist?

LH90

ERR 03 when attempting to create a consist is often a result of not having control of the locomotive. Review the manual for the consisting process.

Another cause is mismatched firmware versions between the throttle and command station. Older systems which have been upgraded may also exhibit this. One solution is to attempt a system reset using another LH throttle.
