A rare generator OTIS LIFT, now with WORKING LAMPS! (fixed!)

To make up for our "fix" which was pretty basic, I've described another mrmattandmrchay animation what we believe the cause was.
Another QUALITY NOT QUANTITY production (1 month to edit, finalise and then to stop tweaking the video!)
Just to point something out... the "wired in series" part was just to demonstrate this is just to prove that this is NOT how it's connected. I did mention this at the "conclusion part" and a few times beforehand, but I just wanted to clarify that! The bulbs are therefore likely to be connected in Parallel. :) Thanks

[@MichalM]

I'm so stupid for not asking this! The left lift, and ideas whether: It was completely replaced with the ecodisc or just fixtures and logic replaced It was originally another old Otis lift The machinery from the old left lift is still in the motor room If the left lift actually existed before the Ecodisc was put in

[@mrmattandmrchay]

It's easier for them to abandon the old lift machinery and start again with standard MRL framework with the motor at the top of the shaft. Trying to put the MRL machine in the old motor room would create unnecessary work with having to divert the ropes up here and back. Also you have to think about companies and profits - again, quicker and easier to pull the old otis out completely and fit a standard lift than spending time modifying the cab to accommodate the new lift. These would have both been 2x Otis lifts. Maybe the management didn't have the budget to replace both at the same time.

Wow all lamps is fixed but the up arrow lamps is not working

[@Paul-mv1sj]

Thats awesome! I wish I knew where that was so I could go see it!

[@MichaelAStanhope]

Id suspect that the bulbs are actually wired in parallel since there are indicators burned out or missing on the outside of the car on the ground level indicator and call lamps, if it was series, none of those indicators would work, but the same basic idea though. I suspect that more than likely it was more likely a ground issue more than a short. A faulty ground (or earth) would cause dim lamps as you show on the video, and when you move it back and forth, you essentially clean the dirty or poor ground as you say. Just my theory on the thing, either way you look at it, good on you to get that thing working again. Hopefully the owners decide to keep it in service as long as possible. Hopefully the other one was just taken out because it was beyond reasonable repair? I've seen that happen here in the US since sometimes its cheaper to revamp it rather than repair it, especially with these old relay based logic units. Not to mention the median age of repair men who can service them are between 70 and deceased now a days. I hope you can see the motor room, because, you know, relay porn!

[@mrmattandmrchay]

Thanks for the message will reply properly a bit later but just wanted to point out that the "wired in series" part was to demonstrate how it "cannot be" wired in series :)

And in this case you are right, this is more than likely a faulty ground rather than the "short"

[@DELROYJOHNSON73B]

Some of arrow cover was still missing... Where they gone is???

[@Clement-xy9iv]

Wow ! This lift is amazing ! Can't wait to see the motor room ! For me it'd make no sense to wire the bulbs in series, I mean you'd have to get a dedicated supply for each lift that has a different amount of bulbs (that would cause big problems of over-voltage). And also in the car, all the bulbs are working but not on all the floor landings, so It's obviously not in series. Wasn't you worried about being shocked while operating the floor indicator (I mean, it's 250V AC!)? Anyway, if all engineers where like you, world wouldn't be that cheaply made today.

[@theGamerzx3]

It makes no sense to wire lamps in series since if just one fails all the others will stop working

This lift is one of my favorites…. I was petrified of them but I loved how fast it was and I loved this bell… it would be great if you did a revisit ( you may have already did but I may have missed the video) just to check if this beast is still there great video as always

[@dngunder]

Oi! About the display being wired in series; highly unlikely. Although these bulbs (looking into the direction arrows at the doors) really look like 12v bulbs. Also it adds up if you do 110v divided by 9 (floor and cab indicators) is 12.2 volts. I'm not sure, it's just a theory

[@MichaelAStanhope]

i'd suspect 24v over 12v. If they were in series, then yes, 110v div by 9 would make sense, but in a parallel circuit the overall resistance of the bulbs wouldn't matter. I don't have any experience with these so I can't say with any type of authority. Of couse with the age of this particular one, 1970's would be my guess by the styling, its still very possible it is running on AC mains current.

[@mrmattandmrchay]

I thought that was the point of the video to demonstrate why it ISN'T wired in series. See the "conclusion" part where I state that they are NOT wired in series. That part was just to prove a point that they can only be wired in Parallel. :)

[@dngunder]

Rare generator lift pt. 4: testing the cuircuit lol. I see what You mean. It wouldnt make sense to wire It in series.

[@ultraheroi4]

Many incandescent christmas strings had a system to short out the bulb when its filament opened, so it was easy to see the burned one. It was a thin wire coated by a really thin white material wound around the terminals inside the bulb at the bottom. When the filament went open the full AC voltage appeared on its terminals and blew away that thin white coating, shorting the terminals. It is a possibility that these lift bulbs are wired in series and have this system. But I consider more probable that the supply to all these bulbs is current limited with a resistor in series so a short circuit blows nothing.

[@Techcraft15]

I agree, the theory of a short is a good idea! I also have encountered such problems. Well, I'm am not an egeneer (too young (17)), but I am a proud owner of a Williams pinball machine. Some of the Solenoids, had the same dirty short, as the lamps in the elevator. This made the solenoids not functioning, and the fuse blew randomly.

[@SeanBZA]

Could also have a current limiting resistor there, to allow the inrush current in the lamps to be lower. The resistor is rated to survive even a shorted output without failure, and is common in industrial equipment with indicator lamps, where the power supply has a resistor to allow lamp cold resistance to be gently started with a lower current, so the lamps last longer.

[@abpsd73]

I would have to say the lamps are parallel connected, since the 3rd floor indicator didn't work outside of the lift, but the one inside the car did work. I could see a loose connection on the common lead affecting the lamps in the car, but there would be a separate common from the machine room to the call buttons. On the other hand, when you lose the common connection in the car, all the unlit lamps in the system act as resistors providing a high resistance common feed. This would explain the dim car lights. Were the call button lights and external floor indicator also dim?

[@MichalM]

Yes they were

[@KXY5]

How did you get the permission to fix the bulbs?

[@morthren]

Nice fix 👍

[@Vandooz]

I wonder why the Doors slam a bit?

[@SAMIEWALLFORD756]

Very old doors! Maybe that is the service might keep on or replace the doors machine to fixtures make formal works. How was think good comfort for sure, hmm?!!... 🤔

[@caroleast9636]

The lamps were always wired in parallel and in this era they would be 110 volts. However many floors there were, the same lamp bulbs could be used. It was common practice to use an indicator lamp in a spare holder as a simple test device when fault finding in the controller. One end clipped to earth, the other end as a wandering probe chasing various points on a circuit until the lamp didn’t light when it should’ve.

[@maxlxl]

I think the bulbs are connected in parallel. It's still possible that a short circuit or a high resistance may dim all the other bulbs as long as they use the same power source.

[@mrmattandmrchay]

Absolutely. I think people are misunderstanding the "wired in series" part...this was to prove how it "cannot be" wired in series :)

[@VOLTRONDEFENDER4440]

Yea short circuits on the indacator could affect the landing indactor definitely not a lose connection as if it was the landing calls and indactor would have stil Been on!

Hello Matt

[@OliverHarrington]

Hi MrMatt! What a great video. I have a silly question to ask you, and it’s probably because I’m American. I’ve noticed that in some of your videos, the lifts that you film use a strange floor numbering where the floors go 1, 3, 5, 7, 9, etc. They only seem to do that in older lifts, because the new ones use the standard floor numbering. An example is the lift in your “An Old Lift Means Properly Stuck!” video. I’ve never seen that here in America. Do you know why they do this? Thanks!

[@MichaelAStanhope]

Alot of the lifts or elevators that he films are in old housing blocks are i've noticed many times there are ones for even and ones for odd floors. I could be wrong, but it seems to fit.

[@mrmattandmrchay]

Hi, No it's not a silly question :) The video you are refering to is split level car park. So when you drive in you are on level G, then you go up a ramp to the front of the car park, level 1, then up the ramp to the next level to the back of the car park, level 2. So each level is split. There are 2 lifts at the back of the car park that serve levels G, 2, 4, 6, while the lifts at the front server B, 1, 3, 5, 7. Coming out the lift that I filmed, if you exited at B then entered the car park, you could walk up the ramp to level G. Some tower blocks have ODD and EVEN lifts. To save money, there is a dedicated lift for G then EVEN numbers, then another one for G and ODD numbers. If a lift breaks down, then the resident just has to walk up or down the stairs to get the other lift. So in conclusion, if you see numbering 1, 3, 5, 7, then yes, there are other levels inbetween which are probably not served by the lift in question

[@OliverHarrington]

Ok, I see. That’s really interesting. (By the way, I do hope you get properly stuck in a lift someday...)

@mrmattandmrchay If this fix you did with this Otis worked, do you think it could also work with the M6 Hilton Park services Otis? While I am aware the lift they’re is currently out of action, if it were to be fixed would you be able to do it?

[@mrmattandmrchay]

Hi, well this is a bit of an open-ended answer, because the answer is, 'it depends what's wrong with it!'. If the Hilton Park lift needs parts that are no longer available, then it becomes difficult to fix it. As there are two lifts side by side, everyone that needs to use a lift (remembering it's only one floor) will use the modernised passenger lift instead. If this breaks, then the new passenger lift is going to be easier to fix that the old otis. So going back to the original question, no such thing as a 'usual' fault, and there's also 'almost' no such thing as fixing a lift by simply moving a display panel slightly!! ;) Looks like I got lucky here!

[@liftlad1400]

@@mrmattandmrchay Ah this makes sense, obviously now that I think about it, something else may be wrong with it and it being a nearly 60 year old lift then the part may not be available anymore (plus, when I went there it definitely didn’t seem like the most up-kept building so due to the neglect, multiple things may be wrong :))
