Here is a user component for a Willey Vogel centralized lubricator. These are used in a lot of european machines. They were bought out by SKF and are used in many modern CNC machines as well.

The lubricator typically has a pressure switch which needs to close after running the pump for at least 10 seconds. If it doesn't close, there is likely a leak in the system or the pump never ran (ie fuse blown). It also has a fluid level switch which will open if the fluid level is too low.

To use the component, typically this is added to custom.hal:

#central lubrication
loadusr -W lube.py
net lube-run lube.run => hm2_5i25.0.7i77.0.0.output-02
net machine-is-enabled lube.machine_status <= motion.motion-enabled
net spindle-on lube.spindle_status <= motion.spindle-on
net lube-ps-float-sw lube.pressuresw_floatsw <= hm2_5i25.0.7i77.0.0.input-14

The component can be downloaded here: upload:lube.py

There is a little fileformat error in the original lube.py and it does not start with Python as it should.You can open lube.py with VIM and do a :set fileformat=unix it should work fine! Or you use this upload:lube(fixed).py and rename it to lube.py it should work properly.
