Otis has never had run count tied to belt life, with the exception of you are allowed to replace a singular belt if it has less than 100,000 runs on it. If you have a PULSE unit the belts are good until the PULSE says so (aside from physical damage) with the exception someone hasn't done a learn run on the belts over 100,000 runs. If you don't have a PULSE unit belts need to be replaced every 5 years regardless of run count.
