Rescuing persons in dangerous situations after the CNC retrofitting
If the machine was subject to a subsequent retrofitting with CNC controlled drives, the fol-
lowing additional dangerous situations such as squeezing and sticking of parts of the body
may result hereof.
If the machine had been switched off in a dangerous situation using the Emergency-Stop
function, it is no longer possible to actuate the axis by means of the electromotor in order to
rescue the squeezed person.
In this case it is necessary to release the machine manually.
This releasing of the X-axis and of the Y-axis is performed using an appropriate tool (e.g. a
flat wrench), which is inserted on the hexagon nut at the shaft end which is opposite to the
drive.
It is only possible to release the Z-axis using a separate handwheel which is inserted on the
free shaft end of the manual crank drive.
WARNING!
It is imperatively necessary that the tools are available to release the machine in case
of a dangerous situation.
Therefore, keep the wrench and the handwheel always in close proximity of the CNC
controlled machine.
