FCU menus
MODE "M4:: Filter from to" (performance of automatic filtration)
MODE M4 "Filter from ... to..." enables the FCU to assume control of an
external filtration unit (e.g. OF5C). The external filtration unit will be controlled
thereby in such a way that the oil cleanliness in the tank to be monitored will
always
be within the specified limits.
If the lower limit value is reached or if it is not met, then the FCU will switch
off the unit to be actuated and the test cycle time begins. After the test cycle
time has elapsed, the FCU carries out a testing measurement (100 ml) and
checks whether the measured values lie within the limit values. If "yes", then
the test cycle time begins again; if "no", then the device is switched on in
order to filter the fluid.
If the test cycle time setting is below LIMITS 0 [min], then this function is
switched off.
Typical applications:
Long-term monitoring and filtration of the oil
cleanliness in hydraulic systems and
documentation thereof via an online printout.
MODE "M5: Measure Autostop"
MODE M5 "Measure autostop" enables the number (1 to 100) of single
measurements to be programmed via the FCU’s high-pressure port, after
which measurement operation is concluded automatically.When online
printing is activated, the result of the last measurement is additionally
outputted in the form of particle counts (absolute value).
Typical applications:
Routine analysis of the cleanliness of a hydraulic
system using a defined number of measurements.
MODE "M6: Autostop pump"
MODE M6 "Autostop pump” enables the number (1 to 100) of single
measurements to be programmed via the FCU’s suction inlet, after which
measurement operation is concluded automatically.
The integrated pump starts up when the OK/START button is pressed.
The first measurement begins immediately after the set start delay.
(The start delay is used to air-bleed and rinse the FCU)
When online printing is activated, the result of the last measurement is
additionally outputted in the form of particle counts (absolute value).
Typical applications:
Gauging the oil cleanliness of a tank or an oil
sample.
