Optional Load Weighing System - MCi iControl User Manual

Optional Load Weighing System

iControl uses load weighing information to make intelligent dispatching decisions. If the load
weight is very light, the controller can be programmed to limit the number of car calls allowed
(anti-nuisance). The controller can be programmed so that at a certain load weight the lobby
landing door timer is reduced, thereby initiating the process of moving the car out of the lobby.
When the load weight exceeds a pre programed value, the controller can be instructed to bypass
hall calls. And, if the load weight exceeds a predefined maximum, above which it is considered
unsafe to move the elevator, the controller can prevent movement. This application typically
includes a visual or audible warning to the passengers that the elevator is overloaded.
MCE has three load weigher options:
• Rope Tension (LW-EMCO) from EMCO - measures the tension of the elevator's wire ropes
(see "EMCO Load Weigher Installation and Calibration" on page
• Isolated Platform (LW-MCEIP) - measures the movement of the car's isolated platform
and can only be used for elevators with isolated platform cars
on page 5-63).
• Cross Head Deflection (from K-Tech International) - measures the deflection of the cross
head beam.
