Abstract
A method of automatically feeding lubricating oil to bearing parts of various machine elements using a microcomputer whereby various settings, progress of the settings, and display of the operating state of a lubricating oil feeding apparatus can be easily identified in a user-oriented manner. According to the method, the remaining operating time is displayed on liquid crystal displays (LCDs) after the lubricating oil feeding apparatus is installed to facilitate the identification of the elapse of the operating time, the operation of a motor for discharging a set amount of lubricating oil is controlled, and various displays such as the overload of the motor, shortage of a battery capacity, elapse of the lubricating oil replacement time, etc., are displayed by icons on the LCDs. The method includes initializing the microcomputer to drive the lubricating oil discharge motor by one revolution when a power is initially supplied, setting a discharge amount of the lubricating oil, selecting and setting the number of operating months, controlling the operation of the motor so that the lubricating oil is discharged according to the set number of operating months, and displaying an elapse o…
