Hello

Can anyone point me towards a source for the manual for the Lenz LE4024B decoder? Tried Google without success.

Trying to sort out why the front light is continuously on regardless of direction and any of the function buttons. The rear light works fine.

Thanks

Bill

Does anyone know of a factory reset is available with this decoder?

Lenz99CV8 = 33

Use CV 8 to read Lenz Manufacturer as ID 99, if confirmed then, Write a value of 33 to CV8 for a reset.
Thanks . Tried that but although I can confirm CV 8 as 99 and rewrite to 33, the decoder reverts to 99 and now the light function F0 makes the motor run faster. GRRRR

Hmm, vaguely remember and recall someone else had one of these decoders, that one was particular troublesome.

If you are meaning you did a Read back and CV8 reported back as 99, this is correct.

CV8 by definition is hard coded into the Firmware as Read Only, irrespective of what value written to it, it will always return back the value of 99.

To prove and verify that the value of 33 in CV8 actually works, try the following.

Write CV1 to change address to anything other than 3 and a maximum value of 99.

Read back CV1 to confirm the new address.

Then CV8 to 33 to preform a Reset, then a Read back on CV1, if the address has changed from the value previously entered and has defaulted back to address 3, the assumption is the Reset has worked.

Tried looking for the Massoth Service Tool template I wrote for this particular decoder, no luck, must have returned the original decoder template along with the decoder.

If all else fails, I'd be happy to have look at it, if you are in a mind to post the decoder?

Hello
Did as you said and unfortunately the fault is still there after a successful reset. If you could have a look at it, I would greatly appreciate your help. My email is bill.tubey@gmail.com if you would kindly send me your address.

Thanks

Bill

After a good nights sleep the Old Grey matter clunked into gear, amazing what one can remember and recall.

Rain showers have put to a halt to anything useful outdoors, tapped away on the keyboard and modified the decoder template, the more observant will have noticed a few changes, the Lenz Decoder is Old Skool, await the arrival of the decoder which is in the post.

(God or the Devil will determine when it turns up, our postal service is hit or miss up here in the wastelands of the frozen North East, well actually more miss than hit!)

Hi Bill, given your decoder a good look over, this might explain some of the decoders odd behaviour, await further instructions.

Very nearly missed it at first glance with the naked eye, required a Jewellers Lupe for a closer inspection.

shorted "output" transistor would definitely leave the light on all the time.

According to the manual, that is output A, which is the headlight.

Can't make much more sense than that!

I don't recall asking for your input, do me a favour and butt out of any thread I'm dealing with.

That's completely uncalled for. No one is the font of all knowledge. If you and the OP want to work on this in private start a PM.
