10-7 Tuning in Automatic Mode

10-7-1 Hoistway Auto-tuning
1. Install all the switches before executing hoistway auto-tuning: DZU (upper leveling switch),
DZD (lower leveling switch), leveling plates for each floor, LSU (upper limit switch), LSD
(lower limit switch), ULS1 (first one upward forced deceleration switch), and DLS1 (first one
downward forced deceleration switch).
2. The installation position of LSU (upper limit switch) should be upward higher than the leveling
of top floor, and DZD should be ON before LSU activates. The installation position of LSD
(lower limit switch) should be downward lower than the leveling of top floor, and DZU should
be ON before LSD activates.
3. Set the running speed during hoistway tuning (Pr.04-03 Hoistway Auto-tuning Speed). The
slower the speed, the accurate the tuning. The suggested speed is 0.25 m/s.
4. Set Pr.03-24 (Constant Running Protection Time). If the time that the elevator auto-tunes
from the bottom floor to the top floor exceeds Pr.03-24 setting time, the auto-tuning fails (fault
code F141). If necessary, set Pr.03-24 to a larger value before auto-tuning, and then set it
back to normal values after finishing auto-tuning.
5. Change the control panel inspection switch to inspection.
6. Set Pr.03-01 (Highest Physical Floor) and Pr.03-02 (Lowest Physical Floor).
7. Set Pr.03-00 (Hoistway Auto-tuning) to 1.
8. Change the control panel inspection switch to automatic.
9. When floor indicator from hall call and inspection are flashing alternately, it means the
elevator is in hoistway auto-tuning. The elevator automatically moves downward to the
bottom floor until LSD (lower limit switch) activates and then stops. After stopping for five
seconds, the elevator automatically moves upward until LSU (upper limit switch) activates
and then stops. After stopping for five seconds, the elevator automatically moves downward
to the leveling position of the top floor, and then stops. Then, the auto-tuning process is
finished.
10. The values obtained from auto-tuning are saved in Parameter Group 09 (Floor Position 1)
and Parameter Group 10 (Floor Position 2).
11. Change the control panel inspection switch to inspection.
12. Set Pr.03-67 (Brake Test Starting) to 1 to start the braking force test.
13. Change the control panel inspection switch to automatic.
