Z4000 disassembly

Kenjr ·
In an earlier post, I reported I had a transformer that the current was not stable on the right channel. My research strongly suggests a loose internal connection (outside connections are tight). Also swapping to another transformer corrected the problem and then hooking up the one in question the problem returned. Question is there anything I should be aware of in opening up the transformer to check for loose internal connection? Also, the handles on this transformer seem much looser than...

The first issue of Z4K's had no adjusters and no friction tensioners installed, though there is a channel in the case molding to enable installing them. The parts are readily available thru MTH. Just call Midge she will set you up. Rod

Is there a way to leave Z4000 handles up on power up?

PhoebeSnow ·
Hi all, I currently power my home layout with a Z4000 and two power bricks (Z1000 and Lionel power house), run through 4 channels on the TIU. I have it all running through a power strip and a Christmas light remote, so I can turn the power on without climbing under the table. This is great, except I have to reset (bring down and back up) the Z4000’s handles each time I cycle the power, or else the red overload light stays on. Is there any way to disable this behavior so that I can leave the...

Is there any way to disable this behavior so that I can leave the handles where they are and only use the Christmas light remote to turn on and off the track power? No, there is not. However, you can operate the Z4000 remotely using a Z4000 Remote Commander receiver and handheld, or the receiver and a DCS Remote. Everything that you need to know about DCS is all in MTH’s “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook...

Hindsight, being 20/20. 18 volts and 6 amps is a lot of power to run a crane. Checking actual voltage probably done after meltdown. I had a similiar problem. Where those output wires plug into the power board the socket failed. Most likely a poor connection. My 20/20 Hindsight is do not waste a Z-4000 throttle running lights at 16 volts and 8.5 amps. Normal parameters but time of use pushed it over the edge.

Re: one TIU and 5 tracks

George S ·
The issue you face is less about the TIU and more about how much power you need on each of the 5 tracks. Do you have a sense for how many engines you will be running simultaneously and how long of a train and whether the cars are lighted? Each of the two main Z4000 handles give you 180 watts of power. That is 10 amps each. You can't max these out without throwing the breaker on the Z4000. The most I have seen a train pull in command mode is about 1.8 amps. You could certainly pull more with...

Atlas turntable power

Hi Guys, working on my turntable this weekend. I have 14 lines coming off. Im trying to figure the best way to power each line.  Do I need to run a separate line to the port terminal block for every one or can I wire two terminal strip close to the turntable then one line to PTB ?  If I can should I use a heavier ga wire from each TS to the PTB ?  Or do you recommend a separate transformer for this? layout is 9x22 with 3 loops and the turntable...

Re: Atlas turntable power

You could put a terminal block near the T table and run one set of paired wires from a separate tiu channe to the terminal block )(fixed 2 or 1 one the var set to fixed) . From the terminal block add a on/off toggle to each track. Using a spare channel will insure a great dcs signal. I would use the same z-4000 handle for power, It's not like every track is going to be powered up at once with the toggles.

Re: Is there a way to leave Z4000 handles up on power up?

Barry Broskowitz ·
Rod, can you shed more light on control via the DCS remote please? You would use DCS to create Z4K Tracks and use the remote's TR screen to raise and lower voltage on the transformer. For details, refer to pages 97-101 of The DCS Companion 3rd Edition. Everything that you need to know about DCS is all in MTH’s “The DCS Companion 3rd Edition!" This book is available from many fine OGR advertisers and forum sponsors, or as an eBook or a printed book at MTH's web store!

Sure you can... They can be programmed to operate just like fixed 1 &2 Menu/System/ DCS set up/ Select the var channel and hit FXD. The channel is now in fixed mode and will remember the setting until you change it back. (same commands however the fxd is like a toggle switch. It changes the channel from fixed to var to fixed with each press. The remote will tell you what mode you've selected.

Re: one TIU and 5 tracks

Engineer-Joe ·
Have you heard about Barry's book of DCS? It would be helpful for you moving forward. I could guess and try to help you but I really need more info. You can only hook up so much track to any one TIU channel. You can divide each channel by connecting to distribution blocks or even just using wire nuts or soldered wires. Usually a larger gauge wire pair is run to a central location and then divided up to each track block. TIU inputs can be jumped so that more than one channel gets power from a...

Kevin, If you set your layout up in blocks and stick to the 12 track discipline you can run as many trains as you desire. I use 2 Z4K transformer on multi levels. It's not just the power but how many different track pieces you have that degrades the DCS signal. Power is only part of the reason you use the block technology to set up DCS layouts. The use of LED lighting in your trains, and thru out your layout, with low voltage switches also helps. Having enough power is only part of your...

Wireless trip circuit for emergency stop

Wireless trip circuit for emergency stop This wireless E-Stop system is used with a custom E-Stop and circuit breaker panel (shown).   As a result I now have several ways to cut power to the track in an emergency.

Sounds like you are overloading the Z-4000. Either get another transformer and split the load(use anothe TIU output) or run less powered engines and lighted passenger cars. I am not 100% sure but you might be able to run four outputs off the TIU base with four different inputs for power, plus power the TIU base with a Z-750 brick. Lee Fritz

Re: Wireless trip circuit for emergency stop

If I understand correctly you are remotely controlling 12V DC by removing the AC line power from a 12V DC wall-wart, HO train transformer set to 12V DC, or the like. Since you already have 12V DC available, here's another option; you have the remote fob on the left and a 12V DC receiver module with relay and screw-terminals. Is there something special about the AC remote outlet you're using that makes it particularly suited to your Emergency Stop application? Big box stores sell similar...

Re: MTH Z4000 onboard breakers not tripping

Oman ·
The Z4000 is an electronic power supply. It probably is current limited to less than 15 amp. So, even with a dead short it will not deliver a large amount of current. A 180 watt transformer, which I believe the Lionel brick is, would probably deliver more than 50 amp, if a dead short was applied and it would do that, although briefly. I think many underestimate the Z4000 because they don't understand it.

I would say you can do a hand check for heat, or use one of those cheap thermal devices before you open a Z-4000 up. All the new stuff I see has lock washers and thread lock on them. If running heavy loads at high amps, feel the terminals for excess heat. If none, leave alone. G

Was this Z4000 of Korean,Chinese or Thai (Thailand) manufacture? I and several friends all have 20-30 between us.Interestingly, it appears the earlier Korean Z's have had the most problems,I've fixed several with loose handles and pots.. The Chinese Z's seemed to be made with lighter/thinner materials,the housing/handles . The most recent Z's made in Thailand have had no issues and seem to be the most "robust"and the workmanship/ internal components appear to be superior.

@Boomer - would you know the range of serial numbers for the different manufacturing locations? That is the target for our curiosity, really. Since our club ad members have so many Z4000's and with so few problems reported, we are wondering if there is a serial number range / batch that are more prone to problems.

I have seen that. It happens with the nut inside that holds the connectors in place being loose. It is not something that happens with one release. It is not an issue related to any number. Alan is correct. I have one on the layout that was given to me with that issue. I run several Z4K transformers and have opened all of them to check for this issue. Easy to fix.

It appears to me that the meltdown was on the outside from a loose connection most likely from a spade connector or wire being loose. Loose connections like these will not trip breakers or fuses.
