Installing The Floor Leveling Magnets - MCi iControl User Manual

Installing the Floor Leveling Magnets

In a typical, front-door only, installation, a single 6-inch strip magnet placed in the web of the
rail (hollow of the rail curve),
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 placed on the opposite
side of the rail and a second set of floor leveling sensors is used.
Note
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

• The magnet must be attached at an angle of about 12 degrees from the rail hollow

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.
Caution
At points where the rails are attached or where rail sections meet, the clearance for the sen-
sors 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.
In situations where the rail hardware compromises the running clearance of the sensor
assembly, we suggest doubling up the magnets at all floors. Extra magnet strips can be
ordered through MCE Tech Support.
