Warning
If there is a power cut or if the toothed belt breaks, the
moveable mass will slide down. Uncontrolled moving
masses can cause injury to people (squashed fingers) or
damage to objects.
S Make sure that the DGEA−... is driven only by motors
with integrated spring−loaded holding brake.
S Check whether additional external safety measures
are necessary in order to prevent damage in the event
of a fracture of the toothed belt (e. g. toothed latches
or moving bolts).
In this way you can prevent the moveable mass from
sliding down.
These brakes are not suitable for braking masses in movement (they are subject to
wear). They hold masses at a stand securely in position.
