re:T1

Dover bought the patents from Swift and the T-3 is nearly identical to it...there is no T-1.The t-3 is good equipment but the t-4 is better.Of course there is also a t-2...my opinion = garbage and it had a generator too!

Is the T-2 a IBM type relay controller with the horizontal selector ?

ibm relay controls with front panel and selector are known as a composite controller

T1 controler

There Was a T1 controller it was a solid state version of the T2 controller. the T1 was designed by turnbull elevator of canada, it used a reed stick system for terminal backup. it used pulse generators in the shaft for positioning. T1's only were generator drive , and were obsolete before they were installed. T2's were generator and scr drive. to my knowledge there was only 3 or 4 job's installed that used T1.

T-I do exist

Dover brought the Canadian Turnbill IC 2000 to the US and renamed it the Traflomatic I. There are around 100 T-Is running in Dallas and another 25 or so in Denver and San Fransisco. They use a loop stick that is the same as used on the T-II. You will not find a manual because Dover never wrote one.

These replie are by real dumb asses

Yes , there are Dover T-1's and mine are generator driven. There are not many of them , but I work on about 12 of them. There are about 50 pages of print/board prints. We have our own electronics lab on the job to rebuild our own boards , and they get some really wierd problems, so anyone who tells you there is no such thing as a T-1 is a dumb ass that has never seen one. My dad is a field engineer of over 20 years experience , and has never seen one , but i work on them every day. They are a huge pain in the ass.

T-I's, Yes they do exist and they were the first venture into high rise gearless market with Turnbull machines, however the T-I is not a Turnbull design, they are a copy of the original Swift controller, we installed the first version in K.C. in the AT & T building, and were constantly changing out boards, mufflers, etc. etc, until a compatible system was found, units actually ran very well despite articles in K.C. Star (Local newspaper), and yes, they did evolve into the T-II which was still a copy of the Swift controller and so on and so on.

Sir, A T2 is nothing like a Swift, copy or other wise. The Swift copy design came in with the T3. The T2 was designed in the time curve of the early 80's when the elevator company's where trying to evolve from Relay logic and they all where groping for a better design. Otis with the elevonic 101 and 401 was in this time period and are equally fu**ed up as a T2. I hate to admit it but it was US's design of the 1200mp that really was the best at the time.... to bad they kept trying to go the cheap route because they really led the feild at the time. Oh well, at least we are all through that now. Otis 411's or Thyssen tack 50's are now really nice to work on.
