Hello,
I have a T450 posi track that has an error code M7504 Drive No Communication fault on site. We have replaced relay and fuses, done earth wore and checked mains controller for bent pins or bad connection.
I am after any other suggested diagnostic test or experiences from other operators who have problem solved this fault?
Thank you
