Floor Leveling Magnets
In a typical, front-door only, installation, a single 6-inch strip magnet attached near the hollow
of the rail curve (left side), See “Magnet position on the rail (side view)” on page 6., is used to
indicate the level-with-floor position for each landing at which the elevator car will stop. If the
car has rear (or side) doors as well, a second 6-inch strip magnet is attached on the right side of
the rail and a second set of floor leveling sensors on the right side of the iLand is used.
Blind Hatch - False Floors - Floor leveling magnets must also be positioned in the approxi-
mate location of all false floors. Check the Hall Fixture Location section on the Hoistway &
Machine Room Wiring (MRW1) page in the job prints. Information regarding false floor set-
tings can also be found on the iView Floor data tab (Controller > View > Configuration > Gen-
eral > Floor data). False floors are considered to have only front doors. False floor magnets
should be installed only on the front door side.
There are three important dimensions to keep in mind when attaching the floor magnets:
• The magnet must be positioned so that, when the car is level with a floor, the magnet is
lengthwise between the Up Leveling and Down Leveling sensors (See “Magnet position on
the rail (side view)” on page 6.) and centered on the Door Zone sensor with the South pole
surface facing out.
• The magnet must be attached at an angle of about 12 degrees from the rail hollow (See
“Magnet position on the rail (top view)” on page 6.). (This aligns the face of the magnet
with the leveling sensors.
• The “thickness” of the magnet strips (the distance from the outer magnet face to the rail
behind the magnet) must be considered so that some magnets do not “stick out” farther
than others. (This ensures that the gap between the sensors and the magnet face will
remain consistent at different floor levels.) The iLand assembly automatically compen-
sates for some rail distortion using the Position Encoder wheel and the two guide rollers.
At points where the rails are attached or where rail sections meet, the clearance for the sensors may
be reduced by clamps, bolts, and other hardware. Check your initial floor leveling sensor adjustments
at the worst of these points to make certain the sensors or other landing system hardware will not be
damaged when the car runs past these points. Check along the entire rail to ensure that the clearance
between the face of the sensor board and the magnets is 1/4 inch (K 1/16 inch). Magnets may be
stacked to increase height if needed.
Warning! Damage due to mechanical contact is NOT covered by warranty.
