Landing/Positioning System
Depending upon job requirements, Motion 4000 may use an encoded magnetic tape landing
system (ELGO) or a perforated steel tape system (LS-EDGE). This section describes both sys-
tems. LS-EDGE NEMA 4X/12 systems use stainless steel hoistway components and a sealed
sensor head but are otherwise installed just as are standard systems.
LS-EDGE
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;
one row for front openings, a second for rear openings.
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 the CAT-5 electrical cables required to connect the sensor to the car top
interface box.
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.
