- trigger the lubrication routine
- regulate the duration of the idle time between two lubrication routines
evaluate such system parameters as:
- lubricant level
- number of cycles (monitoring)
If faults occur, one or more output signals, or indicators are available to help the machine's operator take the appropriate action in regard to the machine or system. This protects the machine or system against severe damage.
In circulating lubrication systems, the machine's control unit usually assumes control of the centralized lubrication system. Devices are available to analyze the data from the system sensors. In normal or faulty operation of the centralized lubrication system, these devices make the output signals available for further analysis.
