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.
