Elevator Group Control System Introduction
The SJT-WVF5 Group Control System is composed of Group Control Card QKB2 and every distributed elevator
main control board (BL-6 or BL-3 or BL-2000/3000.**).
It is applying the serial communication network CAN centralize system to communicate with all elevator
controller to exchange information. After gathering all the information, the microprocessor unit will begin the
logic analyzing and computation on it, following by outputting the relevant commands and responses. It can
achieve up to 8 cars group control with maximum 64 floors each elevator.
SJT-WVF5 elevator group control system can achieve the following four kinds of operating mode:-
1.1
On Duty Mode
Elevators are assigned to homing floor to serve up peak traffic during the preset time (refer to SJT-WVF5 user
manual for setting the homing floor)
1.2
Off Duty Mode
One elevator is assigned to serve up traffic, the rest of the elevators in the group are assigned to serve the down
peak traffic.
1.3
Balance Mode
Hall calls are being divided into a few regions so as to serve the hall call registrations as soonest as possible.
1.4
Standby Mode
During Balance Mode operation, if no car call or hall call is made for 3 minutes, the elevators will be assigned to
standby at the first floor of each region, this is to increase the efficiency of attending hall call registration.
Note that if the elevator is faulty, or in Attendant mode, Inspection mode, Parking mode, Fireman mode,
Independent mode, then it will be removed from the Group control bank.
The operation and setting of each elevator in the group control bank shall be referred to SJT-WVF5
