ABSTRACT:
A multi-function lubricating oil feeding machine control apparatus is provided that responds to different conditions, and includes an oil feeding machine having a controller mounted thereon. The controller comprises a power supply circuit, a microprocessing unit, a multiplex scanning circuit, a motor drive circuit, a status display circuit, an external status input interface circuit, a status output interface circuit, and a function setting circuit. The oil feeding machine may be set for intermittent feeding of oil according to a set time value, or a number of rotations of the work machine, or to feed oil after the starting of the work machine. Additionally, the previous time value or number of rotations may be memorized and accumulated in the next count, so that feeding may start after a specific value or number of rotations has been reached. The external status input interface circuit may be connected to different kinds of detectors or sensors such as a counter, a liquid level sensor, and a pressure sensor to provide other functions. The status output interface circuit may be utilized to transmit on-site conditions to monitoring personnel located remotely from the site, via radio signals or wires.
