A lot of editing went into creating this video, building plans, animations, voice overs and everything timed perfectly to music. It's what you'd expect from the mrmattandmrchay channel - QUALITY NOT QUANTITY.
Pronounced 'Ack-kon-ic', this is a very rare lift control system which was way ahead of it's time in the 1970s.
The mrmattandmrchay channel has teamed up with THELIFTDRAGON to bring you a future video that goes towards explaining how this unique system works.
Manufacturer: SCHLIEREN (later became Schindler)

Thank you again for putting all the effort together to make such a thorough and detailed video on these truly remarkable lifts and the really interesting building in which they're located! I am glad that I was able to help you on the subject of the Aconic controller and it has been a very interesting journey for me as well so far, studying all the old manuals and reading into what the engineers of Schlieren invented here in the 1950s. I am looking forward to creating part 3 with you and to dive deeper into the subject. Also thank you again for linking my video of the Aconics, timing has been a good coincidence and I'm really glad that I was able to film this extremely rare group of lifts.

@srpacific Год назад

I spent a lot of time in (working) elevator rooms a few years ago on a contract job. We audited about 500 elevators throughout a government agency, including some that were over 80 years old. It was really cool to see this and it brings back some memories of opening up a machine room not knowing what decade the actual equipment would be from. In some cases they modernized 1950s elevators to 80s standards and left the old electro-mechanical cabinets and motor-generators behind. I’m not sure what the maintenance standards are like in the UK but in North America the elevator contractors are focused on new builds and modernization and do not care about service and maintenance contracts. In some cases one technician will be responsible for 150 elevators all over the city, each needing about 5-6 hours a month in code-required service. Well you do the math, they simply aren’t getting the service and not one of those 500 elevators was even close to meeting the A17/B44 code standards for North America. Even though it’s required by law! Thanks for the videos!

@SeanBZA Год назад

Yes, I had 2 lifts, and both got the correct service, such so that Schindler used the one as part of the annual review from the Swiss parent, as it was a good example of the era lift, and was in good order. Even went and painted the motor room floor, and put all the warning yellow paint on moving parts as well. Had a stack of spares for the unit in the one corner, especially vision panels, with the pig glass wire in them, as those were kind of expensive to order each, but not so when you bought 5 at a time cut to size.

Meanwhile in my country some landlords award their lift/elevator maintenance contract to a 3rd party company e.g. 9G that's different from the lift manufacturer, maybe because its cheaper. We also had a shortage of lift technicians to service all my country's lifts maybe because such a career is seen as more menial here

@38911bytefree Год назад

This must have been cutting edge back in their days. By early 70s transistors proved to be reliable for any application. They struggled a bit with power applications up to late 60s. But for signal control this was the way to go. They can swtich millions of times without deteriorating, and this reduce maintenance. You will still see relays where high voltage or power need to be controlled. But for logic control this was the perfect choice. I imagine that back on this era, we weren't so sure about solid state yet and many other companies just stuck to the safe an proven relay logic. And because all the engeneering was used to it, while moving to solid state would require another different set of skills.

And yet again, MrMatt has the answer. I came across this exact controller in the Agfa Gevaert plant here in Antwerp. I always wondered what it was, because in the 17 years i'm into the buisness this was the only time i've seen this controller. Turns out it's the elusive Aconic. Sadly, this lift was decomissioned in the late '90s. The freight elevator in the same motor room, that probably had the same controller, was modernised by us KONE with an LCE cpu and KDM drive unit.

Having found your channel a few weeks ago I am truly hooked! The attention to detail in your explanations and graphics is fascinating and I’m learning a lot already. You capture the feeling inside these buildings beautifully as well, the music and filming make you feel like you’re in the room with these beautiful machines, their quietness now all that’s left of a once bustling and full of life building. Having never really paid much attention to lifts in the pass I can see the incredible work that goes into them and how they become almost their own being in a building. Keep it up and I can’t wait to see more.

@abpsd73 Год назад

I imagine fault tracing and troubleshooting on one of these lifts would have been quite daunting for any technician accustomed to working with relay logic. Having to trace a signal instead of hearing an audible click of a relay and being able to readily see the position and condition of the contacts, even with the tech at the time they could have had a bunch of status LEDs to guide a technician as to what the I/O of a particular cad was doing. Electronic enough to [hopefully] increase reliability but still antiquated to be unable to run self-diagnostics.

@CFRTrainSpotter Год назад

i cant wait for part three, was worth waiting this long for this video to come. its a big shame how such advanced tech (and rather interesting building) was abandoned after only roughly 25 years. as for the building itself, its said that the structure itself is in great shape, but due to the sick building syndrome, its not known if it will be demolished or undergo severe rebuilding.

@RedWolf1989 Год назад

It always surprises me where RU-vid's recommendations lead me. At first I thought this was just another Lost Places channel, but than I realized it is mainly about lifts. I didn't even know that there were people interested in these enough to make a RU-vid channel about them, but in the meantime I found out there seem to be quite a few. Until now I was actually happy to see a lift being modernized. I don't find old lifts scary, but I didn't like them, being old and run down, rumbling and shaking. while I found newer ones much nicer, moving smoothly from one floor to the next, with modern looking buttons and floor indicators. However now that I know the elaborate relay technology behind the older lifts build before modern electronics were available, and especially the electromechanical floor selectors, I'm fascinated by them. So much effort and engineering just to move a lift car up and down! Now I feel said about every one of these replaced by modern technology, despite knowing that they aren't museums pieces, but part of a building's infrastructure, so sooner or later they will have to be modernized or replaced either for economical or for safety reasons.

@dykodesigns Год назад

The Aconic controller looks like an Analogue computer to me. Interesting design with those plugin modules. The circuitboards look very artisan, a bit like my father’s hobby electronics projects from the 70’s. Definitely a hand drawn layout.

@SeanBZA Год назад

Very much digital DTL logic there, with likely 24VDC power rails, and a few bias voltages as well for the logic. not all that complex, basically emulating the old relay based controller, just with transistors instead of relays, so that they would last longer, and remain operating with minimal care other than clean air and dusting. Likely faults were still in things like interface, switches and lamps, but the core logic likely was mostly fault free.

Transistors as plug in modules, on the assumption that they, along with diodes, are the more failure prone items, so put them into plug in modules that are mostly identical, so that you can simply keep a half dozen spares in the room, and quickly plug in a replacement, and send the faulty one to be repaired.

@mrmattandmrchay Год назад

Thanks for the comment and yes, fascinating system and plug-in transistors. I'm not sure that I'd like to fault find this though - imagine randomly swapping out transistor boards until the lift starts working properly again! The know-how must have been very specialised! Did you notice that some of them say 'do not swap'? Wonder why, as TheLiftDragon says that the resistor blocks are the same, just newer design.

@SeanBZA Год назад

@@mrmattandmrchay Well, they would have a few variants of the transistor blocks, so fault find to a board area, then swap out the transistor blocks with the spares one at a time, and see if fault clears. No worse than in any industrial control unit, where you isolate to a region of the controller, then put known good boards in, or swap from an identical good unit, and see if the fault moves. Saying do not swap is just those might have been a later modification, with slightly different internal wiring, so you have to swap the transistor block along with the blue block, as the old and new do not intermix, though the interface to the rest of the unit is the same. Plenty of times i did board swaps in avionics to see what was faulty, then take the now known faulty board, and fix later on after sending the unit back out as serviceable.That way you get the urgent job fixed fast, and can troubleshoot the fault, often a known fault you have marked down for that card, and fix at leisure, being able to do a good job.

Motorola house numbers, though, looking at the case style, it was likely all plain regular 2N2219A and 2N2907A transistors, house coded from the Motorols JAN TX production line, using the transistors that had failed the more rigorous JAN TX elevated temperature cycling, but still passed the more relaxed industrial testing cycle. To pass the JAN TX in the military and aerospace certification you had to have zero failures in a batch of 100k devices, but commercial and industrial you could have up to 10. All passed at room temp, especially in the mid 1970's, where Motorola had dialled in production on those lines to be consistent batch to batch, and could have 99 out of every 100 batches pass the full space certification without issue. House coding so that the repair centre can only get them from the approved source, not just go out and buy them, but pay the price for the "right" devices. Vendor lock in for sure, and likely they had to send those back for repair to factory, despite them being commercial parts otherwise.

Cool channel, nice vids, I like to relax and watch your vids. Now, maybe the 6th lift engine is placed higher and maybe even installed first so this lift could raise all other equipment into place. So no external companies would be needed to get the materials to their position. Also when parts would have been needed to replace, they could do it all internal (except for lift 6 🤓. For the boards: you should not waggle them out, but pull them straight out, in order to not damage the side sliders. Like sliding them in: straight, not waggle. Same for the transistor blocks. Interesting are the matrix resistor blocks. I am curious what they were used for, since it is plenty of them. I am used to work with matrix board with diodes. Good idea of having the steel wires going “around”, also on the bottom of the lift, do there is no need for a compensation chain which makes spooky noises. AC to DC, yeah, thats what I worked with too, DC motors can be very powerful and easy to regulate. Did they use DC or half DC? When using half DC (in fact: from AC to DC using only 1 diode) makes the motor even more powerfull. Many greetings from the Netherlands ❤

The topology of the transistor blocks and the (apparent) passive component "grid arrays" they plug into (the BLUE blocks) is very reminiscent of the short-lived 1953 NIST "Tinkertoy" project. I suppose this was both a reliability idea (active components are fully modular and can be replaced by yanking a plug module) and a construction flexibility idea (the logic of a "BLUE BOX" segment is defined by the passive component connections within the "grid"). The fact there's a full grid array in there feels like they're presaging the internal construction of FPGAs or "burnable" memory devices. Never saw anything quite like this in production. The topology seems very "dated", even for the era, but is very beefy and beautifully overbuilt. 1960s integrated circuits were a reality, and by the 1970s they were in commercial use in all sorts of higher-end tech. It's a guess, but I can only imagine this was a move to assure the buyers that the system had a lot of redundancy and deep safety factors. Honestly, if I had been a repair tech back in the day, and I had the drawings, fixing a system like this would have been a dream. Failed resistors were probably pretty uncommon. And if a transistor, or cluster of them, failed or were destroyed, it'd be a fairly simple matter to pull a block, take the thing to a bench, and yank and replace the failed silicon. None of the usual rework tools to desolder and pull parts from a fragile PCB, less risk of damaging a trace or having to put in a shunt wire etc. Takes up more space, but had to be easier to maintain when it went wrong.

Fun fact - those round silver components that look like components are actually shift registers - they each store 512 bits of information, like a tiny RAM chip, each 0.5 Kilobits in capacity. You would need 16 of these transistor-looking components to make up 1 Kilobyte of RAM. Damn strange each module only contains 15 of these 512-bit shift registers, I guess the word length in the logic must have been seven bits? Who knows, but each yellow or blue plug in module is just shy of 1Kbyte RAM.

Hi John. I know what you're saying, and all these "one day" will probably end up in land-fill. But on the other hand, I personally look but don't take anything. Being caught taking something out of a building is classed as theft. Providing you do not 'break and enter' (FYI, we walked in through pre-made openings), then doing what we're doing today is not classed as a criminal act. I'm very sure that urban explorers are a constant frustration and time resource for the police to attend to, and really being caught with something taken from the building will be something the police WOULD take action against. So for me - I don't take anything. You'll see an example of this in part 3. Thanks for the comment.

Should definitely keep it, it's historically significant. The "Get Carter" car park in Gateshead got razed to the ground, an absolute travesty.

At 10:28 There was a Pigeon Nesting In the Motor Lol. That's just Funny. And The Reason was they didn't really fly away is because they where Harf asleep so They don't Fully Think of What a Threat is. Usually it would fly away but because it was kind of sleeping you did not scare them. But I found it Very cute.

26:00 The swiss engineers of Schindler in the time were very careful with transistors as active electronic parts in a lift control system. They made them changeable like electronic valves.

Can I ask a stupid question? I am not an expert. If your converting from AC to DC can't you use a Voltage regulator? attaching two motors seems a little ridiculous and wasteful to me.

@eddiewillers1 Год назад

I'm wondering if this Aconic system used TTL - transistor-transistor logic - as its stepping stone from fully analogue relay control to full digital programmable logic control?

@mrmattandmrchay Год назад

You're probably spot on Eddie. It's a very interesting concept, but wonder how much of a nightmare it would have been to fault find! Swap this transistor block out, does it work, no, how about this one! I bet there were more logic methods to do this, but it would have required a unique skillset and experience with working with this controller type.

@Gazoogleheimer1 Год назад

I believe it is RTL. Possibly dtl but I don't see enough diodes. The interesting thing is how remarkably primitive it is given the age. RTL was 60s tech.

I commented on another post but didn't realize it was 11 years old lol but I'm curious if you have any clacker relay videos

Hi, not sure what you mean by the term "clacker" relays? Do you mean something like this?: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uK3MzMdkys8.html

@chrisbull2448 Год назад

RU-vid sent me to your videos recently, I love your style and passion for the old tech! Another youtube channel "The Pethericks" is restoring a convent in france that has a derelict but not vandalised lift in it. Might be fun one for you to visit - the lift is featured in their latest video. (not affiliated with them in any way, just thought you might be interested)

Many thanks for your kind comments Chris! I'll check it out later :)

@arthurmario5996 Год назад

it's easy to see why so many buildings have broken lifts. an intermittent problem would be almost impossible to troubleshoot. if you "shotgun" the modules, what about all the backplane contacts?

Amazing that this used to be considered high tech.

Hi Matt how you doing mate? and how is Chay? Wow that is a really interesting and weird lift machinery which run the lifts back when they were installed in the late 70s and till closure in 2005 you definitely don't see a lift motor room like that at all today amazing video as always Matt and well edited with the music making it more spooky hope you having a good day :)

@mrmattandmrchay Год назад

Hiya Frosty Gaming, we're great thanks! Chay is nearly 19 and he's working now, has his own car, etc. What are you up to in life now? That's the great thing about derelict buildings, everything frozen in time. Did you notice the music sync'd with each level going up the stairs? All these clips, think of it as "that's two evening's work", "that must have taken a whole weekend", "that took a week", etc, then you end up at 2 MONTHS work!! The main problem I have is finding enough free time to do it all, but I wouldn't do it any other way!

@FrostyGaming8394 Год назад

@@mrmattandmrchay Yeh I did notice the music changing each level going up the stairs very well edited and works great thats nice to hear that Chay is working and has his own car he has grown up soo much not up to much really I do enjoy playing on my video games and going on my gaming pc allot and watching videos on RU-vid especially yours Matt trying to look for a job myself though at the moment but from there thats ally im up to in life at the moment having a good time and thats all.

Looking at the state of some of those equipment cabinets. I'm not sure if they're in their current state from vandalism, or if someone was paid to go around with a sledgehammer and "decommission" the electronics/electrical bits when the lifts were taken out of use. Either way, sad.

@MattyEngland Год назад

I'm not 100% sure, but I think those banks of plug-in transistors may have been forming very early versions of logic gates. So one plug may have been an AND gate, and another an OR gate etc.

@mrmattandmrchay Год назад

Yes, I'm sure you're right there. The resistors cannot really fail, but in case the transistors do they can be unplugged and a new set plugged in. Imagine trying to fault find this..!!

@redsquirrelftw Год назад

That's what I'm thinking too, it almost looks like it was a matrix of resistors, these would have been used as pull up/pull down for the transistor bases, at least that's my guess. Probably designed in such a way that they were easy to manufacture in grids and just stacked.

@StrawberrySunday212 Год назад

IHi there, I have a quick question. What type of lifts had the relays/logic on the ground floor? Where I lived as a child there was a room on the ground floor that had the lifts relays/?logic inside. Also, there was no motor room per se, it was just massive cupboard doors on the top floor that opened and it had a huge wheel in a cage that made the lifts move while the wheel turned. Sorry for a vague description, but I was a child at the time when I saw the "wheel in a cage" as the lift engineer forgot to lock the doors, thus curious kids, me included opened it to see inside. 😱And I *think* I could see right down the lift shaft watching the lift move. I remember a time when the lift got stuck between floors and the caretaker of the building used a big winding handle on the wheel to move it a floor so he could then open the doors and release those inside. ( I was always hovering around when it was anything to do with the lift as it fascinated me) I remember the engineers another time, in the logic/relay room. The door was opened while he was working away so I stood outside the door to watch and I remember seeing a box on the wall and whatever was inside made sparks (this I have now learned was the lift logic/relay) I always remember there was was a sign on the door of tht room warning of "high voltage" and to" keep out". The lifts were installed in the late 60s when the flats were built.

@mrmattandmrchay Год назад

Hi Panthere, I believe you're talking about a bottom drive machine, where the rope are driven from below, then go all the way up to the top of the shaft. I have a couple of examples for you: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8gZaQzdtJwY.html Then look at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8gZaQzdtJwY.html (10:15) and this is the bottom drive motor room. It might be that this resembled a cupboard in the lift that you're talking about. Whether a lift is top or bottom drive all depends on the building design (i.e. where they had room for it). Bottom drive is more expensive as you need more divertor wheels to get the cables to the top of the shaft before they come back down. Everything else you mention about the wheel in the cage, and hand winding the motor is true. This is someone else's video of a lift being hand driven: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mnV4MXmAOPU.html Hope that helps :)

@StrawberrySunday212 Год назад

@@mrmattandmrchayHi. Thanks for replying and sharing the links. Looking at the links, our flats didn't have a basement, but there could have been a trap door in the pit of the shaft that housed the machinery, I do remember seeing the shaft pit, and seeing 2 springs/dampeners but that is all I can remember. I recall The lift shaft was very narrow, as my brother who was full of mischief, used to scare me when in the lift as he could push his arms out and push the walls of the lift and they would scrape off the lift shaft as we moved! The levelling on it was awful as many a time I tripped coming out the lift as the step was sometimes 5/6 inches higher. Do you know what companies made those bottom drive lifts? I have Kone in my head for some reason, but as I say it was that long ago my memory is very vague. Thanks again.
