Figure 18: Selector switch star wheel
Selector switch star wheel
The star wheel can be operated in three operating modes:
Switch position "0":
The star wheel is switched off and thus the material supply to the
mixing section is interrupted, e.g. for cleaning the mixing section
using the cleaning shaft or carrying out a pressure test of the
pump.
Switch position "AUTO" (right):
The star wheel is running in sync with the mixing pump motor and
is switched on and off using the air control or remote control.
Switch position "HAND" (left):
The star wheel is running in continuous mode, independent from
the air control. In this position material can be added to the mixing
section if the pump is deactivated.
