Condition-based elevator maintenance monitoring method

Variable thresholds (662, 663) are generated in response to an average defect rate (669, 690) generated under certain conditions (683-687, 696-698), excesses of which can set an internal flag (670). If an information request (720) or service personnel visit to the elevator site (721) occur, the inte...

Zusammenfassung:Variable thresholds (662, 663) are generated in response to an average defect rate (669, 690) generated under certain conditions (683-687, 696-698), excesses of which can set an internal flag (670). If an information request (720) or service personnel visit to the elevator site (721) occur, the internal flag, or the upward adjustment of the average defect rate (691) can generate a maintenance flag (773) which ultimately results in a maintenance recommendation message related to the particular parameter having a notable defect.
