3.10.1 Installation of Leveling Signals
Leveling signals comprise the leveling switch and leveling plate and are directly connected
to the input terminal of the controller. It is used to enable the car to land at each floor
accurately.
The leveling switches are generally installed on the top of the car. The NICE7000 system
supports the installation of 1−2 leveling switches. The leveling plate is installed on the guide
rail in the shaft. A leveling plate needs to be installed at each floor. Ensure that leveling
plates at all oors are mounted with the same depth and verticality.
