Scanbelt Controller Pull Switch Trip Identification and Pre-start Warning System

The Electrotron Pull Switch Trip Identification and Prestart Warning System is a fail-safe system capable of protecting a conveyor belt system from operational faults as well as protecting the operators working with or near the conveyor belt system. The slack rope system provides personnel with an emergency latching
tripping mechanism that is accessible on either side of the conveyor belt. The tripping mechanism spans the entire length of the conveyor belt, providing a continuous tripping mechanism. This is achieved by the installation of pull switches on both sides of the conveyor belt at 100m intervals. Each pull switch is interlinked via a pull-cable on the one side of the conveyor belt. Pull switches mounted on the opposite side of the conveyor belt are interlinked via steel wire rope. Each trip switch also sounds an audible alarm via two piezo-resistive buzzers, warning operators and personnel working in the vicinity of the conveyor belt of an impending conveyor belt start up. In addition to providing a continuous tripping mechanism, the system also makes provision for the integration of belt fault detection systems such as misalignment, belt tear, spillage and rip detectors. The functionality provided by the system ensures that conveyor down time due to stoppages resulting from operational faults, system faults or emergencies is minimized by providing maintenance personnel with detail information about the cause and location of stoppages via SCADA as well as
via an LCD Display.
