ABSTRACT:
A tamper-resistant, running time maintenance monitor for, and method of, indicating that equipment requiring periodic preventive maintenance is due for such maintenance. The monitor includes a keyboard for manually entering such user-selected data as an individualized access code, a warning time, a maintenance time, and at least some user-selected portion of a message individualized for the user. The entered data is stored and, if it is desired to change some or all of the data, e.g. the warning time, the maintenance time, or the individualized message portion, then the individualized access code must be entered. A running time sensor detects the running time, and a control unit accumulates the detected running time and generates warning and maintenance signals when the accumulated running time respectively matches the stored warning and maintenance times. A display displays an alpha-numeric warning message containing the individualized message portion when the warning signal is generated, and separately displays an alphabetic maintenance message when the maintenance signal is generated. The display also displays actual running time from an initially set starting running time, as well as a service time which indicates the time since the equipment was last maintained.
