OTIS 20HOLCS

I'm looking for a sequence of operation/information for this unit. It is skipping floors in each direction, and I think there is an issue between STX and ST relays.

Appreciate any help.

I seriously doubt there is a written procedure to explain every relay and contact. Does the car go into slow speed and keep going by the floor or is there another sequence the car does. I was a 45 hour adjuster with Otis and adjusted many of these. Never had any written procedure.

What does 45 hour adjuster mean?

12.5% over scale

Thanks
