Abstract

A lubrication system for lubricating bearings that includes at least one lubrication pump for pumping lubricant to the bearings and at least one metering valve for distributing the pumped lubricant throughout the lubrication system to the bearings. The system further includes a lubrication controller in communication with the at least one lubrication pump and at least one metering valve for controlling the lubrication system. The controller has firmware configured to provide a sequence of instructions to perform specified tasks and hardware that carries out the sequence of instructions to perform the specified tasks. In an unconfigured and unconnected state, the lubrication controller can be configured by reprogramming the firmware, to selectively control at least one of a series progressive lubrication system, a dual line lubrication system and a single line parallel lubrication system.

Claims

1. A lubrication system for lubricating bearings, the lubrication system comprising:

at least one lubrication pump for pumping lubricant to the bearings,

at least one metering valve for distributing the pumped lubricant throughout the lubrication system to the bearings, and

a lubrication controller in communication with the at least one lubrication pump and the at least one metering valve for controlling the at least one lubrication pump and for controlling the at least one metering valve, the lubrication controller having reprogrammable firmware configurable to cause hardware to perform specified tasks,

wherein the firmware is selectively reprogrammable from a first state in which the firmware is configured to selectively control a first system selected from a group consisting of a series progressive lubrication system, a dual line lubrication system and a single line parallel lubrication system to a second state in which the firmware is configured to selectively control a second system selected from the group consisting of a series progressive lubrication system, a dual line lubrication system and a single line parallel lubrication system,

wherein the first system is different than the second system.
