Dear members,

I am expanding my layout and will add a 60174 booster. My current set up has some sensor tracks using a Viessmann 5233 track occupancy detector (uses the third rail rather than the ground rail) to trigger switches and signals. Per the 60174 instructions the boosted layout needs to be isolated from the non-booster segment. My question is how to wire the sensing tracks on the boosted section. Do they need to be completely isolated? Can they share a common ground? If I use the S88 does that simplify the wiring or would it also need to be isolated?

Thank you for your inputs.

H
