Equipment malfunction may occur for a
number of reasons: incorrect operation of the
equipment (from overloading, carelessness, or
inexperience), or a normal wearing out of
parts. Electrical controls should be designed
so, that these possible malfunctions do not
allow any additional damage. See chapters 4.5
and 4.6.
The lights on the electrical control panels
should indicate the reason for the malfunction.
Some typical malfunctions and the possible
solutions follow:
THE SETTING OF THE CRUSHER VARIES
The setting of the crusher increases during crushing, but reverts when the crusher is idling.
This is most probably caused by an air lock
in the highest component of the adjustment
system, i.e. the adjusting cylinder.
Bleed the system by opening the bleeding
screw at the bottom edge of the cylinder.
THE SETTING OF THE CRUSHER HAS INCREASED/ INCREASES
CONSTANTLY.
Leaking adjusting piston seal, directional
control valve, check valve or manual control
valve.
Trace the defective part and repair or replace
it.
The crusher has been/is overloaded and the
pressure relief valve has operated/is
operating.
Remove the reason for overload (uncrushable
particle, too small setting) and switch on the
adjusting pump to reset setting.
