lubrication system with a pressure limiting valve. If a lubrication point does not take any grease
from the distributor, the progressive distributor blocks and a pressure of 280 bar (4060 PSI)
builds up in the central lubrication system. Grease emerging on the pressure limiting valve of
the pump element indicates a blockage. Error messages appear in the display of the terminal.
Design of the central lubrication system
An electrically driven piston pump delivers lubricant to the main progressive distributor. Its task
is to distribute grease to the sub-progressive distributors at the correct ratio. Then, the sub-
progressive distributors pump the grease to the individual lubrication points. The lubrication
duration and the break times are controlled via terminal,
