If you do have the prints, Westinghouse I believe use one of their relays for parking. I'm not familiar with the smfa-rel how does that differ from ERL?
This is generally why you can spot mechanics from also rans(if this is what you mean). You never move 'switches/relays', as they dont need to move anywhere. Its the 'contacts' that make circuits so that's what you would move and I think what the poster meant. Spacial awareness is needed sometimes to be a lift mechanic as well as sometimes the ability to 'think outside the box'.
So if this contact is what actually sends the feed to the call relay then I would think I would disconnect these wires from the relay, and then just leave them in circuit at the other end and just terminate them in a connector and leave them be(so if the levels change again this can be reversed. Also mark then so other's can know what they are and mark the print also). Then I would simply copy what the old circuit(to level 1) is, at the g level and replace those 2 wires to the M69 relay.
Vatorman15 is not suggesting to move the M69 relay...
M69 relay provides a function. Micmerci should see this on his print.

Hey mate after seeing the print you sent me, I see what he meant. However im still not sure why that is important as it appears to be a limit to indicate the lift is actually on the main floor ( and drop the relay to stop the lift homing)but it doesn't send the lift there though. Even if you have a home relay with this m69 contact in circuit, you are still in cct to the previous main level of 1 not the level of g which is required now. Wouldn't you have to change where to give the lift a car call( level 1 to level g)?
If you understand what im trying to say.

Disregard this post. I didn't quite recognise the cct it referring to. My apologies.
I'm trying to find out more.

I'm 99% sure that is correct.

Interesting.... Does this system operate like the Otis selector/control in that it doesn't have floor relays and the lift doesn't actually know where it is but just instructed to start/ stop when and where its told? If so what your saying will work as all it needs is a stop input(hs/cs) on Otis). My reasoning previously was I thought this system had individual floor relays and car/landing call relays.
Hey mate, just to confirm I think the poster said the client 'wants' to change the home feature from level 1 to g so when you say it has its B69(is it b or m?) meaning its already been modified or all levels will have this relay? Does this equipment have normal climbing or does it operate like an Otis system and is given a direction and stop inpulse only.
