5.3 Safety devices
The mortar mixer is equipped with the following safety devices:
1.
EMERGENCY STOP switch
The drive motor is disconnected from the mains power supply by the 3-pin safety
module when the EMERGENCY STOP switch is pressed.
To reactivate the control system, the EMERGENCY STOP switch must be
brought back to its home position again by rotating the switch in the direction of
the arrow.
2.
Inductive, electronic proximity switch
The proximity switch in the mixing bowl mounting is energised by the mixing
bowl’s bottom flange and monitors its correct fit in the mounting.
If the mixing bowl is not inserted into the mounting, the safety module prevents
the mortar mixer from being operated. Acknowledgement via the display and con-
trol unit.
3.
Inductive, electronic proximity switch
The proximity switch in the mixing bowl lifting device is energised on reaching the
mixing position and monitors the adherence to the correct mixing position.
If the mixing bowl is not in the mixing position, the safety module prevents the
mortar mixer from being operated. Acknowledgement via the display and control
unit.
4.
Fixed protective cover
The mixing bowl is covered in the mixing position by a fixed protective cover
which encloses the stirrer on all sides.
