Abstract

A plurality of lubricant dispensers with respective microprocessor controllers are connected to a central microcomputer and can count up the number of revolutions of the respective spindle so that local lubrication at different sites of a machine will satisfy the site requirement even if the machine operation and lubrication have been interrupted. The controller of the dispenser includes a data store responsive to the dispensing time which is reset when a new reservoir is hooked up.
