Protection devices
The grinder is protected by a temperature monitor in the motor coil and equipped with additional over-
load protection (Klixon). A micro switch integrated in the upper part of the machine prevents the motor
from starting up if the cover plate or the bean hopper has been positioned incorrectly.
Temperature monitor
The temperature monitor switches the grinder off as soon as the motor coil is too hot. This can occur for
example if the system is in continual use. After the grinder has cooled down, the machine is ready for
service again.
Overload protection / Klixon
The overload protection is tripped if the current ac-
cepted by the grinder is too high. This can occur if the
grinding discs are blocked.
If the short circuit protection has tripped, it has to be
reset manually:
•
Tilt the grinder slightly to the left.
•
Press the button (1) on the bottom of the grinder
and subsequently replace the machine in its original
position.
