1. A lubrication system comprising:
a progressive distributor configured to dispense lubricant to a consumer, the progressive distributor including at least one sensor, and
a control device,
wherein the at least one sensor is configured to determine at least one lubricant pressure inside the lubrication system,
wherein the control device is configured to receive measured values from the at least one sensor,
wherein the control device is configured to recognize a lubrication cycle based on the measured values and to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison,
wherein the control device is configured to determine a maximum pressure, a minimum pressure, and a temperature of the lubrication system,
wherein the control device is configured to associate the average pressure with one of a plurality of temperature windows based on the temperature of the lubrication system, and
wherein the control device is configured to retrieve from a database the one of the at least one normal pressure that is associated with the one of the plurality of temperature windows.
