5.2.2 Parallel Control of Two Elevators
The NICE1000
new
supports parallel control of two elevators, which is implemented by using
the CANbus communication port for information exchange and processing between the two
elevators, improving elevator use efciency.

Function Description
Physical oor, relative to the NICE control system, is dened by the installation position of
the leveling plate. The oor (such as the ground oor) at which the lowest leveling plate is
installed corresponds to physical oor 1. The top physical oor is the accumulative number
of the leveling plates. In parallel mode, the physical oor numbers of the same oor for two
elevators are consistent.
If the oor structures of two elevators are different, the physical oor numbers should start
with the oor with the lowest position. The physical oors at the overlapped area of the two
elevators are the same. Even if one elevator does not stop a oor in the overlapped area, a
leveling plate should be installed there. You can make the elevator not stop at the oor by
setting service oors.
When two elevators are in parallel mode, the hall call and car call wiring and setting should
be performed according to physical oors. Parallel running can be implemented only when
the hall call and car call setting for one elevator is the same as that for the other elevator in
terms of the same oor.
In parallel mode, the top oor (F6-00) and bottom oor (F6-01) of the elevators should be set
based on corresponding physical oors.
