Your answer in one way goes to the heart of the problem, and that is that absolutely none of this information is in the manual. I can only presume that Mr Lenz thinks that humans have inbuilt coding knowledge to fill in the gaps in his manual.

Specifically, there is no delete button or delete function mentioned in the manual (that I can find) so I cannot delete. I could overwrite a number with 0000 but I cant think of another solution. There is a 4 digit method (section 8.3) which I have always used successfully in the past. But I cant get back to 0003 by this method.

Sorry if am ranting but I am frustrated that the manual has none of this info. I would admit to be digitally dyslexic but I would expect the manual to rectify this deficit for me if I read it diligently. Is there such a thing as a complete manual online, or even better is there some accepted language protocol that can be learned ?
But right now I would be happy to acquire or look up a button pressing sequence to get me unstuck.

Hi Andrew,
After 13 1/2 yrs in DCC and working in a large hobby shop (retired now) I have yet to find any system manual that is completely understandable. As a friend of mine says " written by experts for experts"

Now for the LH90 and putting in address's etc.
First I suggest you do a system reset which will put the 90 back to address's 1 thru 8
1. Press arrow then scroll with 0 button until srceen reads SYS
2 Press A
Srceen now shows flashing Y and solid 10

3. Scroll with 4 button until 9 shows
4. Scroll with 3 button until 9 shows
Screen now reads flashing Y and solid 99
5. Press A
LH 90 has now been set to address's 1 to 8
Scroll with A to get each address.
If all 8 address slots have been filled with 4 digit address's etc, and you want to enter in a single digit EG 3 do the following.
1. Press arrow then scroll with 0 until screen reads ADR
2. Press A
Screen will now show 4 numbers (one of your entered loco address's) with a flashing dot above and to right of 3rd digit from left.
3. Scroll with 1 untill you have 0 as first number
4. Scroll in turn with buttons 2 & 3 untill 2nd & 3rd numbers read 0.
5. Scroll with button 4 untill 4th number reads 3 ( or desired single digit address)
6 Press A.
You now have loco #3 dialed in. Open the throttle and away you go.

You don't have to do a system reset each time, I only suggested it to give you a clean slate to start with and give an idea how the LH90 works in relation to selecting different op modes etc.
I hope this helps you.

Re flat batteries in Lenz command.

I have a 10 yr old 01 set, upgraded to V3.5, battery has never been changed, still works a treat.

I also have a six yr old LZV100 command updated to V3.6 battery is still A OK
I know of other Lenz users with systems as old as mine (some older) with original batteries and still working well.

QUOTE (billericaybill @ 29 Mar 2009, 03:24) <{POST_SNAPBACK}>I have a problem with my lenz 90 system stack. I cannot enter the number 0003 to drive new locos with that number on the chip. I know it was there when I bought it but I seem to have stuffed it up somehow. I have followed the instructions in the manual precisely and exactly on several occasions to no avail.

I have in the stack in order

0053 which drives that loco

00.86 which drives that loco but why the full stop in it ?

0.0'0.3. which does not drive a decoder with 3 on it

00.93 which I was trying to set up

0.0'0.3. again


00:91 which drives a loco, but why the colon ?

0.0'0.3. again which was where i was trying to enter 0003 again.

Please can anyone enlighten me as to what i have got wrong ? Also the meaning of these various dots, if any, would be useful.

I would be grateful for any advice on this problem.


Sorry Andrew, I should have answered this post re the full stops etc.

If is showing it means buttons 1 2 3 have been activated as functions on that address.
00.04 means function 2 is turned on. means functions 1 2 3 4 are turned on.

To turn the dots off just press each button untill they disappear in each address.

I am not sure what the colon is. What is the version of your Lenz set 90?

Andrew, the flashing dot means the 90 is not communicating with the command station. This usually happens when changing to new address. Operate the direction switch and communication to command station is restored.

I think situation is possibly a built in safety buffer so new address does not cause loco to suddenly take off if throttle knob is not zeroed when new loco is acquired.
Hope that makes sense.
