I recently pulled the trigger and bought a new ZW-L transformer from Nassau Hobby. It has been working great for the past week. However, today, after a derailment, and brief flash of the red light, the power output on throttle A-U has become stuck at 10 volts minimum.

With the throttle completely turned off, about 10 volts comes out, even though the voltmeter says 0 volts. As I increase the throttle the actual power varies from about 10 volts to 18 volts, while the voltmeter varies from 0 to 18.

As soon as the transformer is turned on, 10 volts minimum comes out, with all throttles turned off, regardless of whether it is in conventional or command mode. All the other terminals: B-U, C-U and D-U work correctly in conventional  and command modes.

Has anyone seen anything like this before? I was very worried about this kind of thing when I purchased the transformer. Despite it's mass and heft - electronics as delicate as a snowflake...

I have reached out to Nassau Hobby. Hopefully they have some idea.

Until then, it's back to my postwar ZW. It's lasted 68 years without a failure.

Is the meter for that channel lit or is the red light on?  I found the manual online and it describes on page 5 the wattage limiting and shorts.

Yes, the meter for the A-U channel is lit. Power comes out with the throttle off and while the meter reads 0 volts.  Real power, not phantom. The circuit protection has failed on this channel also. No red light. No fold-back, no circuit breaker function. So much for their “triple protection”. Am I surprised? No. After all, the Titanic sank with 16 watertight compartments. BTW, if you get a short, there is a loud pop and clould of acrid smoke. I have removed the transformer from my layout. It is not in a safe condition to operate. 

The forum sponsor I purchased it from, Nassau Hobbies, sent me a one line email suggesting that I call Lionel. With their sale complete, their hands are washed of it.  Note to self for future reference. Buyer beware.

I don’t know that it’s a buyer beware scenario. Lionel has sold quite a few of those and you don’t hear much about them failing. From what I hear, those are really nice transformers and things happen. The world is not a perfect place. Consider yourself blessed that your biggest problem is your expensive toy broke.  It is still under warranty so give Lionel a call, get an RMA get it fixed. Nassau Hobby may not be equipped to repair such an item and your fastest resolution will be to call Lionel for help.

Yes, it's an expensive toy. I will be contacting Lionel when they re-open. Lionel is shut down today because of 2.7 inches of snow. Routine weather up north. But in North Carolina, it's a crisis and the NC governor is again back on TV wearing that shirt with that huge, wacky-looking triangle patch.

Sorry Dmax,  but I have to totally disagree with you on your statement about the zw-l.   Our modular club(Pittsburgh Independent Hi-Railers) has been using the same zw-l for years now on more layout setups and displays than I can remember and it just keeps on ticking.   We have a 4 track mainline and the zw-l is used only to power those tracks and nothing else.   We sometimes have 4 passenger trains,  each train from between 7-18 illuminated cars,  running at the same time with no problems.   If a derailment occurs and trips a breaker for that track,  we just reset the breaker and we're up and running again.   Our current display at the 2018 Kennywood Holiday Lights is 67' x 60' with an approx 290' track run to complete one loop of the layout.   So from our club's viewpoint,  the zw-l has been virtually indestructible.

You are very lucky that your ZW-L has held up. A couple of other posters also indicated that their ZW-L has worked flawlessly. That's great.

In my case, a single train derailment caused the transformer to explode with a startling pop, start smoking, and fail electronically.

Gentlemen,

   You might want to put a 10 Amp breaker between your ZW-L so if you get a surge it can be reset and not harm your ZW-L.  I have them between all my Transformers of different makes and never have a problem.   Just a suggestion.

PCRR/DaveDSCN2590

Good idea. But, where are you suggesting placement of a 10A breaker? Between the transformer output and the track? If so, what would this protect? Would it protect the train's electronics from a surge that originates from the transformer output? Or, is this breaker intended for an imagined surge originating from the track and going into the transformer?

In additional to the ZW-L's circuit breaker, fold-back protection, and dynamic power limiting, I also had TVS diodes, and 10A fast blow fuses. That still wasn't enough.  In my case, I am just not sure just how much additional coddling would have been sufficient to protect the ZW-L from itself.

Greg,

I feel bad for you with the experience that you had with the zw-l.   Obviously,  there is some type of factory electrical defect with your particular transformer as a simple derailment shouldn't have caused all that damage.   At Kennywood this past weekend,  a member of the public with the touchy-feely syndrome pushed a couple of cars over and we had a major 3 train,  3 track derailment that tripped the transformer breakers on those tracks.   After re-railing everything,  we reset the zw-l breakers for those tracks and we were up and running again.   We have had many derailments over the years without permanent zw-l damage.    Lionel should take the transformer back and just replace it with a new one for you.   Then they can figure out what happened with yours,  fix it and sell it as a refurbished unit at next year's warehouse sale!

I remember Lionel video on how to reset throttles. I believe you open it up with the post's facing away from you. Then look behind the a-u terminals you'll see a 3 pin buss. I'll try to find that video, it might even be in this forum. Good luck till then, sorry I couldn't remember the procedure, just the just! 

Thanks Ron. But the calibration procedure you are talking about is for a different transformer, the ZW-C Powerhouse. The current discussion is about the ZW-L transformer. I am not aware of any procedure to recalibrate a throttle on a ZW-L.

Greg, I have had good luck with Lionel service; I have sent back 4 locos over the past 4 years and each was returned in 7 business days and fixed; I made sure that I double boxed and padded them a bunch; Lionel service sent them back in the same boxes and packing.

Rick, that is good to hear. I have only had to send back one loco in the last 5 years, and it also came back in a few weeks, fixed correctly. I hope they provide similar support for the ZW-L, especially one which was only purchased a few weeks ago.

GRGER,

I had a similar problem with my ZWL. Had an engine hang up on a foam tunnel wall the grand kids moved and the legacy engine was slipping so hard that the traction tires almost burnt off. Once I realized it I went into emergency shut down and channel A -U would no longer come up to full voltage. Maybe up as far as 5 volts. ( it may have pulled 7 or 8 amps with no breaker trip) I called LIONEL they gave me an RA number and I sent it in. They had it for a month  or so. Anyway  LIONEL repaired my ZWL and sent it back no charge.  I called Lionel to ask what they found but I can’t remember what they told me, ( but they replaced components) and there would be no charge. Before the tunnel incident I had the ZWL for about 2 years. Got the transformer back and it’s working fine. Long story short Lionel fixed my ZWL with similar problems no charge. Hope this helped.

I’m glad they repaired your ZW-L. But it doesn’t thrill me to know that 7 or 8 Amps is all it takes to blow the delicate circuitry in the ZW-L. I have a few sets that would easily draw up to about 10 Amps. What ever happened to Lionel’s much hyped fold-back protection? I know it works all too well on the CW-80 where the blinking green light is a familiar and common occurrence running just about anything. I’m starting to think the ZW-L really is nothing but a 30 pound box containing 4 very fragile 180W transformers, each good for only a Scout type loco, and no more, for fear of upending things. That’s not at all the same as a single, robust, large Wattage transformer. I probably won’t miss mine while it is being repaired. Now that I have gone back to my PW ZW, I can see how much more smoothly my PW equipment runs on a pure sine wave power source. The ZW-L’s chopped wave really beats the heck out of E-units and makes Pullmor motors sound like blenders. I think when I get the ZW-L back, it’s going under the layout as the world’s most expensive power pack running street lights. What a sad end to a very expensive and failed experiment. Usually I am smart about buying trains and accessories that improve operation or bring joy to my hobby. This was a rare setback. Newer isn’t always better. Sometimes just really costly. Lesson learned.

Perhaps when a serious situation occurs, it is actually designed to blow certain components inside to protect the overall unit?  I have had tons of derailments and shorts and never had an issue with it coming back, but something in your case was different.

When you send it in and get it back let us know what they replaced.  That would be interesting to know.

As some have noted, one cannot generalize about a product from an n=1 experiment. Lionel has probably sold thousands or tens of thousands of these, so it would be expected that one or two purchased by forum members (or a lot more) would be lemons or exposed to unusual circumstances that cause product failure.  I don't have need of one now, but there's no doubt I'd be happy to buy a ZW-L in the future based upon other people's experiences, which are pretty close to 100% happiness.

I just talked to Lionel. They are issuing an RA. They stated that service for the ZW-L specifically has a backlog of 4 to 6 weeks minimum. Apparently, I am not the only one, and Landsteiner’s speculation of an n=1 sample population may  be optimistic. I will let everyone know the outcome. 

Well of course he was optimistic.  Lionel can do no wrong, after all...

Hope it gets fixed and you don’t have any further trouble with it.

Wishing you, optimistically, success in getting it back sooner rather than later, and in perfect working order.

I am sorry you are having trouble.  I have no experience with the ZW-L but if you are looking for additional modern power other than the ZWs I would recommend the Lionel 180 bricks.  I have used them for over a decade without problems, and the breaker is super fast.  Further, the trains (postwar and command control) seem to run much better with them than they did with the ZW 250 and ZW 275 I used previously.

Yes, probaly a backlog for all repairs....Plus, there may be only certain people that work on these?

Gentlemen,

   Put the 10 Amp resettable breakers between the Transformers and the TIU or Legacy unit, I thought everyone knew to due this already, I have never had a problem operating in this manner.  Remember also some Transformers eventually break down, nothing you can do about that, I have a Z4K that needs repaired after 10 years in operation, just quit work correctly.  Now my old ZW's are all still working perfectly, some over 40 years old.

There is a very easy solution to this issue.  1. Send the item to Lionel for repair.   2. Ask Lionel for a refund and get something else.

Don't blame the dealer as they have no way of knowing if the item in the box has or will ever have an issue.  Don't blame the dealer if they suggest you send the item back to the manufacture for repair as the new ZWL's are complex devices that there not equipped to service.  Don't go on and on about this problem because Lionel closed due to weather.  The south gets very little snow and is not equipped to handle it in the same way as we are in the north.

Sorry You had a problem, but whining about it here will not solve the problem all it will do is bring out all the nay Sayers.

Just MHO!

 

 

 

 

Some of you guys are, in my humble opinion, too easy on the dealers.  If they sell it, they should stand behind it and at least offer a return or exchange in the warranty period if the customer does not want to deal with the time and hassle.  This idea that when I buy stuff if it breaks it is totally my issue to deal with the manufacturer is not one that you would tolerate in other settings, not sure why folks who drop serious coin in this hobby are so willing to take it on the chin.  Is the dealer in this business solely for the love of the hobby?  

GregR is, in my opinion, too negative about the new equipment, but he has a legitimate beef about the lack of back up here by the dealer and the length of time this will take to get repaired.  To me, those things are worse than the failure of  the item.

Well here is one way to look at it. The ZW-L is considered the Cadillac of modern power. Visit any Cadillac Automobile dealership. A brand new Escalade cost $110,000.00. Walk in the service area. On average you will see 12-16 service bays. Master Tech's average 60-$75,000. per year some more. You will also see a gigantic Snap On tool box in each bay filled with tools that can average $60,000.00. and UP. They don't shop at harbor Freight. What does all this tell you? Nick

The 10 amp fuse is a good idea, but make sure it’s a fast blow fuse.

I guess the train manufacturers could learn a few things, they have prices right with Cadillac, just can't fix the stuff like them

I suspect you are correct Shawn. Their staffing may be limited and there may only be a few people qualified to repair the ZW-L.  It's not like Customer Service would come out and announce a 4-6 week turnaround because they are bogged down repairing the unfortunate self-inflicted surge of repairs related to engineering, production or QC issues.

Meanwhile, I have rediscovered that my postwar ZW actually works much better than the ZW-L, and runs postwar equipment much more smoothly and quietly. I certainly don't miss the chopped-sine "jack-hammer / grinder" effects on my E-units and AC motors. That 30-pound paper weight is now on it's way to North Carolina for repair. I have mixed feelings about that transformer. A small part of me hopes it will fall off a cliff and disappear somewhere in route to Lionel

It's ironic: For all the hype about PW ZW's frying modern trains (which has never happened to me)...who would have thought that a PW train would fry a modern ZW-L? 

GregR posted:

... For all the hype about PW ZW's frying modern trains...

It's only hype, and has little to nothing to do with the transformer or its circuit breaker... it's just a numbers game. All newer electronic gear needs transient voltage protection, it's just that there are so many ZWs out there running trains that there's a pretty good chance of a ZW being involved.

GregR,

A couple years ago I bought my dad a new ZW-L thinking how much liked his old PW ZW. He had years before added a Z4000 along side of that ZW. It took a bit of getting used to but he adapted and accepted the Z4000. My thinking was to replace both the Z4000 and the ZW with a newer model that could do the job of both. 

After a month, the ZW-L got shelved and about two months later he sold it on a popular internet auction site.  He for the same reasons as you did not like how it ran his older PW trains. His opinion is that the PW ZW is the gold standard of how all transformers should operate any locomotive (albeit no BELL button). Apparently the Z4000 made the cut in his opinion and lesser transformers like the CW80 and the Z-controllers never did or will. He could pick up on how chopped waved transformers operated his trains and that just rubbed him the wrong way.

I eventually wound up getting my dad the PW ZW Volt / Amp meter add on an online auction to be used with his old ZW, which he likes a lot.

A long-standing gripe of mine too.  These things may be toys, but they are very expensive.  Not having parts and expertise is just not acceptable.

Although I like all the bells and whistles, I'm contemplating transitioning back to postwar/MPC for my toy train fix and moving to HO or N for the scale stuff.  The PW is easy to repair, and if a $150-200 HO/N loco goes belly-up, it's not a catastrophe.

As far as sending it back to Lionel vs. the dealer, if the item was purchased via mail order, the difference is minor.  Would feel differently if buying in-person - would expect the dealer to deal with it.

the day of the service station is about over. At least for some of the train equipment. The dealer can do nothing. They are in a bad situation.

so, you don't think Lionel would rather produce a old transformet? Sell, it and forget it! Of course they would. This is a issue with product safety and liability. It is what it is...

Well why couldn't they build a larger version of the PW ZW to compete with modern Transformers? Other manufactures still make transformers with wound coils instead of electronics. I don't think it has anything to do with safety and everything to do with cost & features. It's more economical and feature friendly to build electronically controlled transformers vs a coil wound unit.

Whatever you are buying, you should read the warranty first. If you do not like the terms, then do not buy it.

Doug

In Lionel's defense, they have gone beyond their technical obligations for warranty service. First, I am fairly certain that most ZW-L transformers were produced in one or two large production runs, probably more than 3 years ago. So, they appear to have quietly waived their 3-year limitation of coverage in recognition that this product remains cataloged for ongoing sales. The same may be said of the Legacy base and perhaps a few other items. Secondly, they sent me a Fedex shipping label to return a 30 pound item back to Lionel. I was not expecting that concession as the terms of the warranty state that it is the customer's responsibility to pay for return shipping. So, I am pleased with Lionel's response. My opinion of the transformer is a separate issue that has been well stated.

Ray Lombardo stated that many people are too easy on the dealers. This is a complex issue.

On the one hand, many dealers suffer greatly for Lionel's QC issues, taking on uncompensated repairs as a dealer, or under-compensated repair work as authorized service stations. They sometimes take it on the chin and get saddled with unfair expenses like return shipping, to fix and return Lionel products in the interest of providing good service and to retain customer patronage. The widespread nature of this dealer good will and behavior unfortunately prevents Lionel from grasping the scope, magnitude and cost of QC failures. Just imagine the impact if Lionel's entire dealer network began to return everything that arrived back in their stores in defective condition!

On the other hand, some dealers could do a much better job with communication and standing by the products they sell.  I received a terse, single line email from the seller which stated precisely, "I would suggest giving Lionel a call and see if they know a solution" . The email contained no salutation, and there was no name identifying the individual  who sent me the email. What message should a customer receive from an email like this? The message that I received was, "We don't care to address you by name, we want you to go away, and we wish remain anonymous by concealing our name". Perhaps my interpretation is incorrect. Perhaps they cannot repair these transformers. But they didn't care enough to explain.

This is why club layouts use z4000s and not the zwl,  they dont hold up. None of the zw remakes held up. The old zw which isn't that powerful keeps kicking though!! It's not any brands fault it's just electronic devices.  

And very easy to repair (I might add). 

Amen,brother!!  I have a good old 275W ZW that had new rollers years ago.  Lever outputs are set once and forgotten as I have super fast electronic breakers between ZW and TIU inputs.  So far no problems and had several derailment or objects on track and ZW just hums along, no fuss, no muss, no triacs/transistors/diodes to mess up those sine waves!  

To paraphrase: "Nothing comes between my ZW and track, except wires"

Well why couldn't they build a larger version of the PW ZW to compete with modern Transformers? Other manufactures still make transformers with wound coils instead of electronics. I don't think it has anything to do with safety and everything to do with cost & features. It's more economical and feature friendly to build electronically controlled transformers vs a coil wound unit.

 

It took Lionel a long time to get UL approval of the ZW-L, and to please UL they had to take the amperage down a bit.

There are plenty of PW ZW's out there.   Why remake that, and have to compete with the secondary market?

When did the ZW-L get UL certified? According to UL the ZW-L is not UL listed: Lionel LLC UL Products

Yes, Plenty of ZW's available, but none that crank out 600+ watts of power (or have a bell button).

Zw-l hasn't even been out long enough to say it's great and lasts long lol, the z4000 been proven

Neither of you is wrong, based on your experiences.

I have both a Z4000 and a ZW-L.  Both are solid.   I have not experienced any issue with either.

I've had the Z 4000 for 7 years, and the ZW-L for 4 years.

I have the z4000 and is very happy with it.It always tells you there is a short.It runs all my trains be it mth.lionel.kline.I agree with ya on this.

the zw is etl listed

Both marks demonstrate that the product that bears it has met the minimum requirements of widely accepted product safety standards as determined through the independent testing of a Nationally Recognized Testing Laboratory (NRTL). And, as part of that testing regimen, the product manufacturer has agreed to periodic follow-up inspections to verify continued compliance. So, the only real difference between the marks is in the service, and services, of the testing laboratory behind them. It's here that ITS ETL SEMKO's clients enjoy the real differences between UL and ETL. ETL custom-tailored testing, quick turnarounds, and flexible work methods are literally changing the face of the industry by promoting an environment where the testing lab and product manufacturer work more collaboratively - bringing products to market more quickly, more smoothly, and more cost-effectively than ever before.

At first I thought maybe you worked for ETL, but this just copy and pasted from from a web search, right?: http://www.crossbrothersinc.com/aboutetl.htm (about 3/4 way down that page).

The ZW-L was tested by ETL to meet the UL Standard 697. (I believe this is stamped on the bottom of the unit). Yes ETL is a NRTL and their testing is just as tough as UL. UL creates standards and tests (and approves) products to meet those standards and ETL tests products to meet criteria set forth by UL. ETL is a little more than just some vague voluntary accreditation agency.

While the ZW-L is not UL listed, I'm sure it would pass if they put it through the paces.

I'd be curious to know why it wouldn't. I'm sure that the last design PW ZW-R wouldn't pass, but not because of the coil wound transformer. A modern version of the PW ZW would need a lot of other things that would still have to be addressed in the design of any new transformer in order to pass. Atlas & Williams both still sell a nice coil wound transformer, although not as big.

The whole idea is moot, by the time you build a 600+ watt version of the PW ZW, add all of the nifty feature the ZW-L has and build it to pass ETL or UL standards, You'll have a much heavier product, that would be just as or more complex than the ZW-L (mainly due to integrated powermasters & circuit protection). It would probably cost more too.

Electronic Transformers are cheaper to build, and easier to integrate features into... probable also easier to get an ETL or UL certification too.

Update: My ZW-L was returned last week from Lionel, repaired good as new.

Unfortunately, the chopped wave just beats, rattles and grinds the heck out of my PW equipment. I have now hooked up an LW transformer next to the ZW-L with a toggle switch. Whenever I switch over to the LW, the motors and E-units instantly quiet right down and engines run smoothly.

Don't get me wrong, the ZW-L looks great with the fancy meters and cool lights, even if it's useless to me for running trains smoothly.

Now, if I could only find someone who could design a device which was capable of converting a chopped wave to a sine wave. Then I could actually use my ZW-L to run some trains! I might start a separate thread on that topic to explore the possibility.

A couple of thoughts here... the chopped wave will get you more smoke, brighter lights, and better slow-speed performance.  Think about driving a nail into a piece of wood with a series of hammer blows, vs. "pushing" it into the wood with steady pressure from a heavy weight. 

I run a Postwar 2018 and an MPC-era 8042 2-4-2 on our Christmas loop.  True they are quieter on a 1033.  (A lot of the buzzing comes from the E-unit.)  But they will start smoother, and run at slower speeds when being run from the chopped-wave transformer that came with our 1995 K-Line set.  And you can blow the whistle with less slow-down.  We once looked at the K-Line transformer's wave form on an oscilloscope.  It is very aggressive, perhaps as much as 50V peak-to-peak.  I've also seen the chopped waveform from a Lionel Powermaster on a 'scope.  It's aggressive, but not as much so as the K-Line. 

Think about the folks who are likely to run trains with their ZW handles... My guess is that Lionel left it this way on purpose to wring more performance out of Postwar, Postwar Celebration, Conventional Classics, etc.  And in my experience the chopped wave does give better performance.

If the peaks of the chopped waveform are too sharp and the noise is objectionable, you can "round them off" by placing a NON-POLAR capacitor across (in parallel with) the output.  DO NOT use a polarized capacitor with AC!  For maximum safety, even the non-polar capacitor should be in a ventilated metal enclosure.  I would try about 150uF to start, and adjust from there.  200uF would be smoother, 100uF would preserve some of the ripple.  Season to taste.
