LS-RAIL Landing System
LS-RAIL is a cartop pedestal mounted positioning system. The encoding wheel rides the face of
the rail center blade, tracking position, while two sensor arrays detect floor zone and terminal
magnets mounted in the rail angles. MCE can provide a prefabricated cartop mounting pedes-
tal, LS-PEDESTAL, or the installer may build their own.
The system uses capacitor-stored power and non-volatile memory to retain position informa-
tion in the event of a power failure.
The LS-RAIL kit contains the positioning assembly, the required number of door zone magnets,
terminal magnets, and the CAT-5 cables required to connect the sensor to the car top interface
box. If ETS magnets are required, they are also included. Depending on applicable code, you
may have to route electrical connections through conduit. If so, we recommend minimum 3/4-
inch flex so that the modular connectors can slide through without binding.
