2.9.4 Non-return valves
Non-return valves are installed in the outputs of the distribution block to prevent
lubricant from flowing back into the distribution block. All output ports to which
primary lines are connected or which are used to interconnect distribution blocks
must be fitted with non-return valves. Output ports which secondary grease lines
are connected, must be fitted with non-return valves if significantly different
return pressures are expected at different output ports.
2.9.5 Failure of one of the doser segments
If a piston in one of the doser segments gets stuck due to contamination, the whole
greasing system will fail to operate properly.
2.9.6 Closing outputs
An output may only be closed-off after removal of the little plug that seperates the
two outputs of a doser segment. Removing the plug allows the grease meant for
the close-off to exit through the output that remains open (it doubles the output
of the one that remains open). The distribution block will become inoperable if the
little plug is not removed.
