CARGO LOADING SYSTEM DESCRIPTION (3) Proximity Switches Proximity Switch - Door Sill Latch The Door Sill Latches (DSLs) are connected in series. All YZ-door sill latches have to be in the "down" position to let the power supply the Cargo Loading System (CLS). Then the cargo compartment door mechanism will be electrically isolated. All YZ-door sill latches have to be in the "up" pos ition to let the power supply the main CC door opening/closing operation. Then the CLS will be electrically isolated. As the Door Sill Latches are connected in series, if at least one of them differs from the other ones, both CLS and cargo door will be electrically isolated.

CARGO LOADING SYSTEM DESCRIPTION (3) Proximity Switches (continued) Proximity Switches - Conveyance The proximity switches - conveyance indicate if the latch is in the lifted or lowered position. If the latch is lifted, the proximity switch will signal the relevant control boxes: Compartment Control Box (CCB) or Sector Control Box (SCB), to cut the power supply to specific Power Drive Units (PDUs) where Unit Load Device (ULD) transportation movements are no longer required.

CARGO LOADING SYSTEM DESCRIPTION (3) Door-area Door-area Control Box (DCB) Interfaces The DCB is linked with the other control boxes and the Doo rs and Slides Management Control Unit (DSMCU) via CAN bus. The DCB receives feedback from the door sill latch proximity switches via a discrete signal and sends a signal to the Outside Control Panel (OCP) via an analog signal. The DCB has also a link with the Central Maintenance System (CMS) via a bi-directional ARINC 429 link with the Secured Communication Interfaces (SCIs).

CARGO LOADING SYSTEM DESCRIPTION (3) Compartment Control Box (CCB) Interfaces The Compartment Control Box (CCB) is linked with the other control boxes via CAN bus. The CCB receives discrete signals from the Inside Control Panel (ICP) and the OCP. Analog data is exchanged with the OCP. OCP. The CCB receives feedback from the ball-mat area proximity switches via a discrete signal and sends discrete commands to the transverse PDUs.

CARGO LOADING SYSTEM DESCRIPTION (3) Electrically Powered Pallet Turning and Extended T-Shape CLS in AFT CC This option is used for the loading of three additional pallets (88 in / 96 in x 125.0 in lengthwise position in T-shape area) in the AFT cargo compartment. These pallets will be turned in the ball mat area. Additional components will be installed in the T-shape area of the cargo compartment. The Pallet Turning Unit (PTU) is basically the same as the SCB and additionally monitors the pallet turning function. It is integrated in the floor panels and replaces one SCB.
