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: Measuring and switching"
Mode M2 "M 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:
o
The flow (volumetric flow rate)
o
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.
