7.1.3 Mode "Filter to" (carry out automatic filtration)
Description
By using MODE M3 "Filter to" the FCU can control an external filtration unit (such as the
OF5C). The external filtration unit is controlled in such a way that after the average level
of five measurements has reached or dropped below the given limit, it is switched off by
the FCU. The example set out below explains the process.
Typical application
To flush hydraulic systems and log the oil cleanliness achieved via online print-out.
