Many elevator enthusiasts and hobbyists use (an MIT-developed platform) to build interactive models of the Otis Gen2 system.
A visual inspection is the first step. The belts should be checked for any cuts, gouges, or signs of the internal steel cables (which appear as a metallic sheen within the yellow or black polyurethane jacket). The Otis PULSE system provides 24/7 monitoring, and a Magnetic Flux Test is used to measure the resistance of the steel cables within the belt. A significant "scratch" or gouge on the surface often precedes a drop in resistance, triggering an alarm. These are shallow, linear marks on the polyurethane
Because debris is the primary enemy of polyurethane belts, hoistway cleanliness is paramount.
