When installing leveling plates, ensure that the plates at all oors are mounted with the same
depth and verticality. Otherwise, the leveling accuracy will be affected. The recommended
length of the plate is 80–200 mm.
•
More leveling input signals need to be added if the door pre-open function is used. In this case,
you need to increase the length of the plate properly. For details on the door pre-open module,
contact the local agent or Monarch.
3.10.2 Installation of Slow-Down Switches
The slow-down switch is one of the key protective components of the NICE7000, protecting
the elevator from over travel top terminal or over travel bottom terminal at maximum speed
when the elevator position becomes abnormal.
The NICE7000 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 two ends
of the shaft to the middle oor one by one. Generally, only one pair of slow-down switches is
required for the low-speed elevator. Two or three pairs of slow-down switches are required
for the high-speed elevator.
The slow-down distance L indicates the distance from the slow-down switch to the leveling
plate at the terminal oor. The calculating formula is as follows:
In the formula:
"L" indicates the slow-down distance;
"V" indicates the F0-04 (Rated elevator speed);
"F3-08" indicates the special deceleration rate.
The default value of F3-08 (Special deceleration rate) is 0.9 m/s

. The slow-down distances
calculated based on different rated elevator speeds are listed in the following table:
