The electronics and coil in the drive unit are also monitored by
temperature sensors. If the permissible temperature threshold
is exceeded, the drive switches off. The LED (GG) in the ser-
vice part of the drive unit will glow red. After cooling (about 15
min.), this LED will go out and dispersion can be continued by
pressing the Start-Stop key (EE).
When the PTFE bearing in the dispersion tool becomes worn, it must be replaced.
See the Cleaning and Maintenance chapter.
Wear can be recognized from the increased play between the rotor (BB) and the
PTFE bearing (AA) or the increased level of noise.
The dispersion tools will heat in the area of the interlock casing (JJ) (see Chap.
0); in particular, the sealed dispersion tools can heat to the point that there is a
risk of combustion. Take precautions when replacing the tool and dismantling the
tool.
