I need to do some work on a Xetron 7111B. I downloaded the Xetron 7X manual but the info in it does not look exactly like the 7111B. The 7111B is a fairly large unit with several motor driven cams. Does anyone know if the circuit info in the 7X manual covers the 7111B operation.

Edw, I remember this unit from way back. I looked thru all my stuff and can`t find anything. If I`m correct in my visualization, it`s quite a large cabinet, fairly high, quite a few timeable cams and I may be wrong but I think the relays were dc. Anyway way it dates back to quite awhile ago.

The relays are all 12VAC. The unit is working but some of the cams are off time. Guess I'll just play with it and figure out what each cam switch does.

A manual was found at one of the other theaters.

The 7111B is essentially two maxi-7 automations with the auditorium module all in one box.

There are three timers. One for each machine (changeover) and one for the auditorium functions.

They cue and operate like the Maxi-7 system.
