6.16.2 Strainer wheels monitoring
The pressure of the hydraulic drive of the strainer wheels is constantly displayed on
the R-Touch in load monitoring. When exceeding a warning threshold ( 2 ) determined
by the driver (adjustable between 50% and 100% of drive pressure), the warning icon
flashes on the R-Touch. Simultaneously, a warning tone sounds. For setting the
warning threshold see page 138 .
Automatic speed adjustment
Automatic rotational speed adjustment increases the speed of the strainer wheels
when the bar graph of pressure indication ( 3 ) for the strainer wheels is 20% below
the warning threshold ( 2 ). Increasing of the rotation speed is visibly indicated in the
bar graph ( 1 ) for automatic rotation speed adjustment. Should the automated system
adjust the speed earlier, then only the warning threshold ( 2 ) is to be set to a lower
level. Should the speed adjustment come into effect later, then the warning threshold
( 2 ) is to be set to a higher level.
ADVICE
If automatic speed adjustment should constantly indicate the maximum value, then a
higher cleaning stage must be selected or the lifting speed must be reduced.

Stone blockage detection
If a strainer wheel is abruptly blocked, all upstream drives and the driving power switch
off automatically. A warning indicating which strainer wheel is blocked appears on the
R-Touch. . Simultaneously, a warning buzzer sounds.
This allows you to start searching for the problem directly on the affected strainer
wheel.
