PROGRAMMING the EMCO VK-3v Control Unit
Description of Operation
The purpose of the EMCO Load Weigher system is to measure the load in the elevator and pro-
vide usable information about the load to the elevator controller. This information is used for
pre-torquing and for dispatching decisions, e.g. light load anti nuisance, heavy load and over-
load.
The system usually consists of a sensor or group of sensors mounted on the elevator's wire
ropes and a control unit. The sensor(s) provide a signal to the control directly related to the
amount of load in the cab. The load weigher control accepts this signal and provides usable data
to the elevator controller in the form of an analog signal.
