-LIFT MACHINE ROOMS and LIFT SHAFTS are DANGEROUS environments, they’re multiple risks such as crushing, electric shock or the risk of falling!

beautiful installation 👍
Siemens---best Quality!
Great control that was designed 30 years ago
Thank you for the comment, Yes they are still in my opinion some excellent controllers if maintained properly, but sadly not really energy efficient they soon will be replaced. Engineering effort to vanish...
@@TecStuffLifts I have replaced obsolete automation systems. It's a pity because many were beautifully installed, but can no longer be economically maintained.
Is theese two items on left side tacho dinamo's or encoders ?
And why two of them, redudancy is not correct ansver
What is the purpose of the small pulley in the floor?
It checks for overspeed. If this occurs, the cable is blocked and an emergency brake is triggered in the passenger cabin
@@ConradReichel Interesting to know, thank you :)
Is the motor brushed or brushless
The machines are DC gearless, they are brushed with separately exited field coils
Isn't (what seems to be) the cooling fan on that motor a bit unnecessary? Also that's a lot of electronics just for a elevator.
"Just an elevator"
Elevators are hugely redundant, with lots of safety mechanisms you never see.
Notice the two encoders/resolvers connected to the motor? Each with *four* individual belts? That is engineering for redundancy.
You need to consider the failure conditions of components. An IGBT can fail short, so maybe that's why they used relays.
Of course you can build an elevator controller with just an Arduino - but then someone will lose a limb.
@@vincentguttmann2231 I wanted to write sth similar to that. An elevator is the backbone of a modern highrise building basically. And it just needs to function no matter what, it can't just fall down and leave behind mush in the cabin just because one part failed.
@@sicstar Especially in skyscrapers, were elevators are actually an approved and even necessary mechanism of building evacuation
As the other comments here already mentioned it's all about redundancy, these are some really complex early microcontroller era controllers. Nowadays they are modern chips that can do many safety relevant functions like brake distance calculation, short floor journeys etc, but back then they needed to do it in a redundant discrete way hence the complexity, plus in addition it needs to do the group call dispatching adding some more logic cards to the stack.
The drive machine fan is annoying, yes, but it is necessary as these motors get hot very quickly. These lifts don't recuperate like on modern AC VF driven lifts, the energy doesn't get dissipated in a dynamic braking resistor. As these are SCD DC driven lifts the motor dissipates the energy needed to slow down the lifts.
Hope that helped
Seems like a lot of electronics for an elevator?
The pinnacle of 1980s engineering. This controller was designed over 40 years ago.. 🤷♂
Not at all. It is for redundancy. You cannot just have the control system fail. Human lives are at stake.
he try his best his branes. please make kindness four all humanitarians
I was testing those panels and electronic boards at that time. if there is number "208" in tester sticker, that's me :D
hello my dear. i enjoi but i very sadness. you never show machination four india. why my beauty? my colour good colour. all colour xcelent colour.
