These are shallow, linear marks on the polyurethane surface that do not penetrate down to the inner steel cords. They generally do not compromise the lifting capacity or safety of the elevator but indicate a tracking or debris issue that must be resolved.
If a scratch cuts deeply into the polyurethane casing, it compromises the belt’s defense against moisture. This can lead to internal cord corrosion or uneven traction.
If a building uses a third-party maintenance provider and Otis removes the PULSE monitoring equipment upon contract termination, the building owner must implement a rigorous manual Magnetic Flux Test schedule to compensate for the loss of continuous monitoring. otis gen2 scratch
Though the Gen2 machine sheave is highly durable, over millions of cycles, the specialized profiling on the sheave can experience micro-wear. Any roughness on the metal surface will inevitably transfer onto the softer polyurethane belt jacket. The Role of Pulse Monitoring Technology
The Otis Gen2 is a machine-room-less (MRL) elevator system using a flat steel-coated belt instead of traditional ropes. Its controller (typically or MCSS/OCSS ) relies on non-volatile memory tables—often called scratchpad memory or scratch parameters —to store drive tuning values, floor offsets, door timing, and fault logs. These are shallow, linear marks on the polyurethane
Once diagnosed, the solution will depend on the cause. Gen2 elevators are complex systems; Attempting unauthorized repairs is dangerous and will void the warranty.
Because the Gen2 system often operates in a hoistway without a traditional machine room, the components are more exposed to building dust, construction debris, and airborne particulate matter. If a hard particle (such as a shard of concrete, drywall dust, or a metal shaving) becomes trapped between the flat belt and the sheave, the immense pressure of the elevator cab weight will force that particle into the polyurethane jacket, creating a continuous scratch as the belt moves. 2.
