Workpieces have to be deposited beforehand in automatic or setup mode.
The system must be brought into a safe state (emergency off).
Vertical axes have to be secured with the supplied locking pins for the vertical axes
or with the transport securing device.
Appropriate safety devices (cables, auxiliary supports etc.) must be used to secure
telescope axes against falling down.
Avoid walking under suspended workpieces or vertical axes. Take
special care with telescope axes. Inspect belts for cracks and
tears before every maintenance procedure.
Workpieces must be deposited beforehand in automatic or setup
mode.
Vertical axes must be secured with the supplied locking pins for
the
vertical axes or with the transport securing device.

20 3/d Operating personnel or third
parties are injured during the
manual insertion or ejection of
the workpieces.
Insertion or ejection axes may only be moved in jog mode or with two-hand
operation. The drive configuration is such that only a slow axis speed is achieved
at maximum speed of the drive motor. The operating elements for insertion and
ejection must be configured so that the operator has a clear view of the movement
and cannot be endangered. Areas where body parts could be crushed are to be
prevented with design measures to the greatest possible extent.
Extra attention is required of the operator at manual
workstations.
Only perform movements if no other person is in the danger area
and none of your own body parts are in the line of danger of the
corresponding axis

The supplied screws for assembly have to be used. For the connection of the
supports to the floor, the anchoring suggestion according to the Güdel layout
needs to be taken into consideration.
Fall protection has to be mounted for area gantries.
The operating manual must be read and understood.

10 3/d The risk of potential hazards
becomes too high.
Only drive systems are used that comply with the state of the art and the standards
referenced in the machine directive.
Work in this mode requires a high level of individual
responsibility from the operator/setter.
There is no way to completely ensure that a malfunction of the
control system does not create a hazard by moving the axes.
The operator must therefore try to never be in the possible
direction of travel of the axes and ensure that no third parties are
in the possible danger zones.

x x
10 3/d The effects of a control system
malfunction endanger the
operator or third parties.
The areas of movement are to be enclosed by mechanical safety fences, light
curtains and light grids so that it is not possible to enter this area from any side.
Movements must transition to static states as quickly as possible.
In normal operation, all protective hoods must be closed,
removable protective hoods must be screwed securely.
Required conduct: Inspect the protective hoods before starting
normal operation.
