Operation, continuation
System-dependent monitoring
Main metering device B and secondary metering devices
C, D, F are connected by high-pressure hoses G. This re-
sults forcingly in a functional interlink of the complete pro-
gressive lubrication system.
The structure of a progressive metering device warrants it
auto-monitoring and the monitoring of the operation of the
complete lubrication system.
As soon as a piston in a metering device has a failure, it
blocks the relevant metering device.
If any metering device fails, due to the functional interlink
also the main metering device blocks. This means, the
complete progressive system is stopped!

Visual monitoring
The metering devices can be equipped with an indicator
pin that is connected to the piston and moves back and
forth during lubricant distribution.
If there is a blockage in the system, the indicator pin stops
moving.
