Delivery of carriers from the system to the Nexus Station
The system can deliver a carrier from anywhere in the PTS to a Nexus Station at any time.
Status: carrier incoming
For a carrier to be sent to a station, the events described next must occur. These events occur when a
send transaction is initiated and again at turn-around of the final cycle to ensure that the destination is
mechanically capable of receiving the carrier. When the carrier lands at the slide plate, the system recog-
nizes it as having “landed.” This the carrier arrival state is initiated by the system.

2 The air valve and slide plate at the Nexus Station are closed.
3 The brake is engaged.
4 The top sensor is cleared in the system.
5 A compartment is reserved in the turnstile.
