FCU menus
MODE "M1: Measure"
MODE M1 "Measurement" is used for measuring oil cleanliness without using
the control functions.
Typical applications:
Short-time measurement of system cleanliness
MODE "M2: Measure and switch"
MODE M2 "Measure and switch" can be used for measuring the cleanliness
of the oil in the hydraulic system, at the same time offering the possibility of
controlling limit relays for signaling purposes. This means that this menu
enables the user to have external devices switched by two relays. An
example of this would be an alarm indicator lamp on a control panel.
Possible reference values for triggering these switching sequences:
The flow (volumetric flow rate)
Cleanliness rating of the hydraulic fluid (indicated according to NAS or SAE
or ISO)
Typical applications:
Signal switching to a control panel at fully
automated test benches.
MODE "M3:: Filter to" (performance of automatic filtration)
MODE M3 "Filter to" enables the FCU to assume control of an external
filtration unit (e.g. OF5C). In so doing, the external filtration unit is controlled
in such a way that it is switched off by the FCU after it has fallen below the
specified limit 5 times.
Typical applications:
Flushing of hydraulic systems and documentation
of the oil cleanliness rating achieved by way of an
online printout.
