LS-EDGE Landing System
The LS-EDGE positioning system uses hall-effect sensors and perforated steel tape to report
position as the car moves through the hoistway. 5.5-inch magnets are used at each door zone.
The system uses capacitor-stored power and non-volatile memory to retain position informa-
tion in the event of a power failure, continuing to capture information for 10 seconds after
power loss and storing the final reading for use after power restoration.
The LS-EDGE kit contains the sensor head assembly, an “L” bracket to mount the sensor
assembly to a uni-strut that is in turn attached to the elevator cab (uni-strut to elevator cab not
provided), steel tape, top and bottom steel tape hanger assemblies, the required number of door
zone magnets and terminal magnets, and the CAT-5 electrical cables required to connect the
sensor to the interface board.
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. Perforations for cable tie wrap connection are provided on the RJ-45 plug-end
of the sensor head.
LS-EDGE allows most hoistway switches to exist virtually, in software, greatly simplifying
installation and adjustment.
