Operational state "TEST MODE"
To ensure a constant degree of cleanliness of the hydraulic fluid, the self-
contained servo-hydraulic linear axis can be provided with a filtering system
for technological reasons/optionally. A clogging indicator signals an imminent
change of the filter element in due course. The clogging indicator features a
visual representation of the degree of contamination at the sensor head.
Depending on the variant of the self-contained servo-hydraulic linear axis the
"FILTERING MODE" may be combined with a test of the optional safety
valves. Therefore, check the variant of your self-contained servo-hydraulic
linear axis in the data sheet.
Status messages of the clogging indicator
Prewarning – filter element almost exhausted, schedule mainte‐
nance
75 %
Diagnostic message present: E2012 01: filter 75 %
Alarm – filter element exhausted, carry out maintenance and re‐
place filter element by a Bosch Rexroth filter element
100 %
Diagnostic message present: E2012 02: filter 100 %

Status messages of the clogging indicator
●
Control operation is interrupted and the self-contained servo-hydraulic
linear axis is retained at its current position.
●
The safety valves are alternately deactivated and the servo-hydraulic
linear axis is "isolated"
●
Highly efficient cleaning of the hydraulic fluid is carried out
●
Check whether the "FILTERING MODE" is to be deactivated
