Lenz LZV Command station issue

[Ashish]

Hi Friends,

I have a Lenz LZV 100 command station which I used after a long time, it showed error 97 issue and I replaced the internal battery. Now when I run the circuit boards outside the housing it works well but when I reassemble the command station in the housing to run, it shows error 97 again. Any tips/ help is much appreciated,
There I son improper fit to any of the parts and the staton assembles with ease
thanks

I have no knowledge of Lenz systems but think an analytical approach may help a little here.

You say circuit boards work outside the house and presumably, without the case but when re assembled, it doesnt work in the house?

Have you tried the assembled command station outside the house, does it still work or not? If it doesnt work, this suggests to me the case may be causing the error 97 due to a short or other battery drain \ leaky earth?

If the assembled command station works outside the house but not inside, is it near a non standard power supply or other electrical equipment that is causing some interference?

The LZV case is metal, check that the leads on the new battery are not too long and shorting out on the case!

As Suzie says, the legs on the new battery might be too long and maybe causing the battery itself to touch the casing. Maybe de-solder it and bend the legs to shorten them.

Thank you for the suggestions Friends I will go through the steps and check, thanks again

Hello Friends,
The battery issue got resolved, now onto the next issue !

I have several locomotives which I was running with a Bachmann Dynamis system and now want to run with the Lenz LZV 100 and LH 90 throttle. I am trying to write addresses for the locos on an isolated track. The issue is this -

I put a loco on the track (Dynamis address 0001) and press the button to switch on track power. the Loco moves forward and does not respond to any of the numbers in the Lenz handheld stack, on switching off track power it stops.

when I get to the PROG - ADR menu and assign a new address, the READ message appears followed by ERROR 2

According to the Lenz manual this signifies reading failure of the Loco decoder, what is the solution maybe a factory reset ?

thanks

The Len LZV 100 is connected to a 18 Volt 1 amp power output

many thanks

The Lenz LZV100 has separate outputs for a programming track. So you just need to connect a length of track to these outputs to programme the decoders.

Thank you,
I now programmed a locomotive (Switcher) to address 0001 and it did make a response when the "send" display appeared, then the number 0001 also appeared
however on exiting the programming mode the Loco is not responding to the throttle on the programming track and on the main track moves forward without responding to the throttle

what am I Doing wrong ?

thanks

Personally, I wouldnt give a loco an address with leading zeros such as 0001 as you have. Id either use an address as 1, 10 or if you want to use a 4 digit address, 1000 or something relevant to the individual loco such as cab side number.

As Ive metioned before, I dont know the Lenz system but, most dcc command stations do not give enough power to the programming track for the loco to move. Unless the Lenz system is different, the loco will not move while the dcc system is in programming mode.

Once the dcc address is programmed, move the loco to the main track. If you've exited programming mode and wired the track to the main dcc output, the loco should be controllable via the address used.

I would reprogram the loco with either a 2 or 4 digit address without leading zeros and see if that makes any difference. Just my opinion though!

the low power is intentional, what I have is a double pole double throw switch so the track can be switched from programming to main with a switch

as a hint, don't do what I did and put the switch where its out of reach from the desk..

Yes, my program track is going to be switchable the same way. Just have to get my head around Flashbang's wiring diagram on his excellent site. Must admit Im a bit nervous at wiring \ soldering it all up as the last thing I want is to destroy my dcc base station!

if you don't already have one, get hold of a multi-meter, check for short circuits before powering it up

I put a loco on the track (Dynamis address 0001) and press the button to switch on track power. the Loco moves forward and does not respond to any of the numbers in the Lenz handheld stack, on switching off track power it stops.

Most likely cause is an internal wiring fault on the loco, which may have already damaged the decoder such that it is essentially running as a DC loco does: track power on, moves; track power off, stops.

...when I get to the PROG - ADR menu and assign a new address, the READ message appears followed by ERROR 2

According to the Lenz manual this signifies reading failure of the Loco decoder, what is the solution maybe a factory reset ?

This confirms that there is either or both of a wiring fault to the decoder, and/or damage to the decoder, such that the Lenz system cannot read the decoder.

I would suggest using a meter on low resistance setting with the loco off the rails:
to firstly check that with the decoder removed, the pick ups are not connected to either motor terminal;
then with the decoder replaced in the loco, there is still no connection between the pick ups and the motor terminals. (Inspect the decoder for damage during this process, evidence by sight or smell of burnt out components is clear evidence of a failure on the decoder.)

If you find there is any connection from this testing between pick ups and the motor terminals, this has to be rectified: that done, if the decoder appears undamaged a reset is the next step. If the reset generates an 'ERROR 2' after several tries, the decoder is probably damaged, even though no physical clue has been observed.

Lenz will only operate short address 1 not long address 0001, although it will program either address. 1-99 must be short addresses and 100-9999 must be long addresses when using the Lenz system.
