Hi Cedric,
Don't you have an extra TSR ? Stepper portion will be the same-- Send a photo of what you have-- Ron Rich

Hi Ron,
There are pictures of the stepper back on page 1 of this thread. It looks like the type of stepper you would find in a 222 which doesn't have that switch. I don't have a pdf of the 201 - I'll have to dig out my hard copy manual to see how that one looks.
Norman.

Cedric,
OK-- You now have confused me-- All "Seeburg Steppers" ( with the exception of those originally used in K or L models) are the same--
I cant find any photo of yours here-- send me one of what you think is "missing a switch" ??

Ron, Norman,
Thanks for your return.
Here a pix of my TSR-1. As you can see, these contactor is missing ( TSR serial 55457)
Welds seem original.
I've another TSR here, belongs to a friend ( TSR serial 41794) There is the contactor on this one.
Thanks guys.

Cedric,
I can't see whats missing on yours-- What are you calling the "contractor" ? Ron Rich

Hello Ron,
Sorry, I want to talk about the switch, and not contactor or contractor
Here you can see easily.
Thanks, Cédric.

Hi Cedric,
I have never seen that switch on a stepper before-- I have no idea who added it, nor why it's been added ? Ron Rich

Hi Ron,
I have been following this saga with some interest. As Cedric previously pointed out, that switch is shown in the TSR1-L6 parts list on page 5133 of the V manual. It is marked item 29 and described as "reset magnet switch assembly"

Although I have now read the description of operation twice and I can see no reference to that switch! Might it have been something like a switch to operate a counter to keep tally of selections coming from wallboxes? It's a dreadful state of affairs having to read the manual!
OK, I have found it on the electrical schematic - it's contact K and what it says in the descripton is "The normally open contact K on the pawl release relay closes at the first operation of the Letter Step Relay to connect the Step Switch Assembly in the read-in circuit of the Memory Unit"

Hi Guy's,
Yep-- I just read the Service Manual too-- lOl- Thanks, Norman, for pointing that out ! It is the "k" contact-- Seeburg used the designation "k", for "Write-in", "forever"-- My GUESS is, that there was some questioning of the 2D21 circuit in ability to fire correctly ? I do recall some discussions of the older gents in the shop and they were talking about the k contact's problems in a V-200 -- I ASSUMED, at that time they were speaking of the "k" contacts in the DCU-- Just perhaps, my ASSunmption was wrong ?? This contact was not on earlier, or later steppers, so Cedric, if your later version is marked as a "code B", I once again, would need to ASSume, it was purposely left off, as it's not shown on the TSR-3 schematic.

Hi Guy's,
Happy to read you.
Your answer makes me think more and more that there was a version (the first TSR1) with this switch, then the removal of this switch during the production year of the TSR1. As you know, I have 2 TSR1 here at home. Mine is younger (serial number 55457) and does not have this switch. The other TSR1 I have on loan is older (serial number 41794) and he has this switch.
maybe someone from seeburg realized that it was possible to do without this switch ..

Ron, Where can I see if I have B Code? the identification plate is erased.  Tomorow, I'll have another TSR1, again on loan, I'll check for K switch. There or not? Will see ;o) Cédric. |

Hi Cedric,
They did not use "codes" on the TSR-1-- just serial numbers-- On 2nd thought, I'm thinking they wanted to disconnect the WI circuit from the stepper,to stop any "leakage", when the TES was being used-- thinking hard about that conversation many years ago-- I remember it well, but not all of the facts-- I can't think of any other reason for it, and in my opinion, it's not necessary--If there and working well, it can't "hurt" anything-- Ron Rich
