Terminal Slowdown Check
1. Confirm the P17 and P18 slowdown position counts, based on job speed. See
Table 3 on page 2-36 for the proper values and for all steps in this procedure.
2. Adjust the terminal slowdown magnets so that they activate 2–4" after the
selector slowdown.
Example
Both up and down car speeds are 100 FPM. Table 3 shows that the up selector
slowdown is 939 counts (each count =
1
/
40
"). Therefore, the up terminal slow-
down magnet should activate 18–20" before the landing. The down selector
slowdown is 683 counts, so the down terminal slowdown magnet should acti-
vate 12–14" before the landing.
Verify Proper Function of the UP Terminal Slowdown Magnets via the UIT
1. In the UIT, scroll to Block Select Adjustments > Adjust Car/Group > Position Sys-
tem > P17, and press ENTER to edit the value.
2. Press UP or DOWN to adjust P17 to one half of the recommended value from
Table 3 on page 2-36.
3. Place the car at a floor below the top terminal landing. This action will allow the
car to achieve contract speed in the up direction.
4. Run the car to the top terminal landing.
• NTST should activate, slow the car down, and stop the car within door zone.
• The controller should log faults (981,2801, 1062, etc.) showing the NTS
system was activated.
In the next step, a metal scribe will damage the tape.
a. If the car does not stop within the door zone, use a marker that will not
damage the selector tape to mark the bottom edge of the slowdown mag-
net’s current location.
b. Use the alignment tool as a guide, and slide the slowdown magnets
down in 1" increments. Repeat until the car stops within the door zone.
5. Restore P17 to the value indicated in Table 3. If the slowdown magnets were
repositioned to achieve proper operation, add 43 to the value of P17 for each
inch the magnets were moved.
6. Scroll to Block Select Adjustments > Adjustment Car/Group > Car Adjustments >
WRT, and issue a WRT Command to save the adjustments.
7. Attach each magnet in its final location with two small beads of silicone caulk.
