2.4.2 Slow-Down Switches
The slow-down switch is one of the key protective means of the elevator, protecting the elevator
from over travel top terminal or over travel bottom terminal at maximum speed when the elevator
position becomes abnormal. The NICE3000
new
system supports a maximum of three pairs of slow-down
switches. The slow-down switch 1, slow-down switch 2 and slow-down switch 3 are installed from the
