Warning
S Make sure that, in the travel range of the
article,
nobody can place his/her hand in the
path of the moving load (e.g. by
providing a protective screen)
there are no foreign objects.
It must not be possible to touch the DGE

standstill.
Fitting in a vertical or sloping position:
Warning
Masses falling suddenly can cause personal
injury and material damage (crushing).
If there is a power cut or if the toothed belt
breaks, the work load will slide down.
S Make sure that you only use motors with
an integrated spring−loaded holding brake.
S Check whether additional external safety
measures are required to prevent the work
load from sliding down (e.g. toothed
latches, moving bolts or emergency
buffers).
Note
A motor from Festo with spring−loaded holding brake holds masses at standstill
securely in position.
This type of brake is not suitable for braking masses in movement.
Frequent braking increases wear.
