Selector Tape Magnet Installation
Selector Tape and Box Inspection
1. Inspect and clean the selector tape. Use a wire brush to remove cement, drywall,
mud, etc., and use fine sandpaper (400 grit) to remove nicks and burrs.
2. After cleaning, wipe down the tape with a clean rag. If the tape cannot be completely
cleaned, it MUST be replaced.
3. Inspect the selector box for damage or defects. The guides must be free of dirt, not
binding on the tape, or extremely loose.
Magnet Placement
• Floor level magnets are the only magnets placed on the front (or car side) of the
tape. See Figure 6 on page 2-22.
• Slowdown and directional magnets are placed on the side of the tape facing away
from the car (back side). See Figure 4 on page 2-20 and Figure 5 on page 2-21.
• Handed references are noted as if facing the tape from the car.
• The magnets have their magnetic south marked with a yellow stripe. The yellow-
striped south side faces out and should be visible for all tape magnets except the top
floor slowdown (NTSD) magnets.
Top Terminal Slowdown & Directional Limits
1. Position the car so that it is level and at the top landing.
In the next step, a metal scribe will damage the tape.
2. Use a marker that will not damage the tape, and mark the tape at the top of the
selector box. See Figure 4 on page 2-20.
3. Move the car out of the way to provide access for installation of the magnets.
4. Determine how many initial terminal slowdown magnets are to be installed.
5. Start placement of the bottom edge of the first terminal slowdown magnet "T" inches
below the top of the selector box mark. Stack the determined number of magnets up
toward the "Top of Tape Selector Box"—line the magnets end to end with the north
polarity facing out (black side out).
6. Start placement of the directional limit magnets 6

" below the selector box mark.
Place two 8" magnets end to end with the south polarity facing out (yellow side out).
The magnets must be extended up the hoistway far enough so that the selector
sensors cannot run off of the magnets at the extreme limit of travel up past the
top floor. See Figure 8 on page 2-24.
Bottom Terminal Slowdown & Directional Limits
1. Position the car so that it is level and at the bottom landing.
