Home Forums General Discussion Technical Questions otis 411 floor position

Can anyone one assist me in the learning procedure of the floor position, on the otis 411.

Yep,do a learn run.

That is about as much of the bait I will take.

Why do you need to learn the floor positions? Did your selector tape break?

E411 with a sppt tape or 411mms without a tape?

Greenpants,you are referring to a e401 with the sppt transducer.
As far as I know,the 411 didn't have a tape,but an encoder on the machine and vanes in the hoistway with an optical reader box.
You make any changes to those,you have to do a learn run.
The only way is with a service tool.

The E411 has a selector tape and SPPT transducer. We have 12 of them on service. These are the old Ward Leonard motor control. Hey Green Pants do you know when they did away with this controller and went to the vane/encoder positioning? It seems these replacement boards are harder to come by these days.

We had a burnt prom, as a couple of units are out of service we have swapped out the faulty promo, however this lift has two extra levels, one below ground and one above the top level served by other cars. We have changed the numbers of floors, how do a LEARN of the floor position and save them?

Is this a 411 with the SPPT and tape? Do you have a service tool?

Yes it is 411, with tape and service tool

Sorry,must have missed that vintage in our area.Never saw a 411 with a tape.

So,with a tape, does it still have a NTB and NTT vane,or something different.Like a magnet and sensor?Or a TM cam and switches.
The service tool,would it be m 2(mcss) calibrate and learn run?

they still make the E311 and E411 for high velocity cars. the tape/positioning system is very similar to a 401 but the board is serial link comm. you dont do a learn run on these units unless unknown levels are added, floor table is inputed with serv tool. vanes in the hatch are just for dz/ adv door opening. if you took the e2 out of another car with different openings you have to change the install params/masks. i dont recommend it if you dont know what you are doing.

Thanks guys, slow process to get the job running again, floor by floor and enter the count. We had no choice in swapping, the original was a little burnt.
Only issue now is that the car stops at all floors but does not open doors on the top two landings, after modifying the numbers of floors.
Quicker the client modernizes the better off we will be.
So if anyone has a quick fix for the above minor issue, would be appreciated.

Those are great units why mod? The mcss and ocss landing bit masks must be in sync or you won't open your doors.

The controllers have been robbed Hoover the years, parts missing, many failures of basic stuff, difficult to get spares.
Thanks for the info, we guessed as much, but ran out of time yesterday.

We just did 45 stories of leveling. Nope nothing quiker. Two people and a good set of radios is a must

Still having problems with the two top floors not opening doors after looking at things it all looks okay, can anyone assist further in the sync of the n
Mcss and ocss
