sc-2

new to this posting problems im having with my layout im very glad you brought that to my attention this will never happen again. i did not go that far in school in the future i will have some one a little more literate then my self do all of my spelling would that be alright with you thank you again kirk

dc,

I also have five of these sc-2s on my layout. I do not have the problem you mention. The fifth in line is the one that I have split between turnouts and accessories. I do not know if it makes any difference where the accessories are in the line up. Are you getting the program run switch back to the run position after the programing? Another thought might you have this SC-2 in a place where it is getting interference from the track signal? I wish I understood these electronic devices better, maybe try moving one that is working correctly to trade places with the one malfunctioning to see if that makes a difference.

Do you have track common coming into the SC-2?  You should have the common to the aux power connector, or you may have signal issues.  Since the SC-2 receives the track signal, it can be subject to signal issues, depending on where it is on the layout.

Kirk:

I use SC-1’s and SC-2’s also.  Per the SC-2 manual, if you are only controlling 2 switches, the accessories still have to be connected to the right-most sets of terminals (ACC-1 & ACC-2) and not to the middle sets (SW-3 & SW-4).  Is that the way you have them connected? 

Also you are limited to controlling no more than 2 on-off and no more than 2 momentary function accessories.  The #97 has both an on-off (motor to power the chain conveyor) and a momentary function (coal dump into a car) which you would wire to either ACC-1 or ACC-2.  The #397 would normally be wired as an on-off.  If your coal-tipple is also an on-off you would need to wire either it or the 397 as a momentary instead to whichever ACC terminals you didn’t use for the #97.  What are you using for the coal tipple?   

HTH,

I have several of these and not all clustered together. I have them under the train table in different places around the layout. On one that had intermittent operation, I hung a loop of wire around it and that increased the SC2's antenna ability to receive signals and it works perfect.

I have a couple more under the table in another location mounted on a hidden table leg - one SC2 is about two feet off the floor and has no problem.

The other is directly under it about a foot off the floor and needs a grounded wire behind it in order to function.
