See the appropriate<strong>ACS800</strong> Firmware Manual for an actual signal which indicates the hours of usage ofthe fan. For resetting the running time signal after a fan replacem<strong>en</strong>t, please contactABB.Fan failure can be predicted by the increasing noise from fan bearings and thegradual rise in the heatsink temperature in spite of heatsink cleaning. If the drive isoperated in a critical part of a process, fan replacem<strong>en</strong>t is recomm<strong>en</strong>ded once thesesymptoms start appearing.
