Intended use: Güdel devices are only used to bring objects to a specific position,
hold them there or move them simultaneously with other machine movements.
No hazardous (e.g. poisonous or explosive) objects must be moved. Güdel devices
must not be operated in potentially explosive areas. The ambient temperature
during operation must be between 5° and 40 °C.
If the intended use is modified, this can result in hazards that are
not covered by the safety concept.

10 3/d When the enable button is
pressed, the operator is
exposed to a hazard due to an
automatic movement triggered
by a third party.
Axes can only be moved individually by a two-hand operating device in jog mode.
In the event of several carriages on a single gantry, the individual carriages have
to be selected using a key switch. The enable button is a "shock button".
For the enable button to be activated, only one safety door may be open and the
others must be closed and confirmed. Safety-relevant parts of the control are
inspected at appropriate time intervals by the machine control system.
In confirmation mode, the operator must pay great attention and
have a high level of individual responsibility. 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.

20 3/d That neither operating
personnel nor third parties can
reach or walk into the
hazardous locations where
automatic movements are
performed. The areas of
movement must be secured
accordingly.
The areas of movement are enclosed by light grids, light curtains as well as
mechanical safety fences so that it is impossible to enter this area from any
direction.
There are door elements or light barriers that allow access to the danger area or to
a portion of the danger area.
The height of the safety fences is described in EN ISO 13857.
Safety shutdown situation:
The vacuum system remains active in a de-energized state.
Door elements: When opening the danger area, a safety shutdown is performed for
at least those drives that pose a hazard in this area.
The door elements are also locked electromechanically.
Light barriers: These are monitored so that when contact is broken, at least those
drives that pose a hazard in this area are shutdown. The distance between the
source of the danger and the light barriers is described in EN ISO 13855.
In normal operation, all protective hoods must be closed.
Removable protective hoods must be screwed securely.
Required behavior:
Inspect the protective hoods before starting normal operation.
Safety shutdown situation: Never step into the area below
suspended workpieces and vertical axes.

10 3/d A person is injured by the
unexpected start-up of moving
parts.
The start-up of the plant without the enable button being pressed or available must
be prevented.
With the permission device pressed, moving plant parts can be moved in a
controlled manner, even if the plant is unsecured.
When the enable button is pressed, it must not be possible for the operator to be
endangered by an automatic movement triggered by a third party.
The lockable main plant switch breaks all main and control circuits.
Never step into the area below suspended workpieces and vertical
axes.
In confirmation mode, the operator must pay great attention and
have a high level of individual responsibility.

The axes can only be moved with reduced speed.
Rotating parts must be shut down securely.
Work in this mode requires great attention and a high level of

your own body parts are in the line of danger of the

Mechanical guards must be placed in the possible flight path of parts that could fly
away.
Safety devices are inspected by means of calculation and trial.
In normal operation, all protective hoods must be closed,
removable protective hoods must be screwed securely.
Required conduct: Inspect the protective hoods before starting

Attachments to moved masses (vertical and horizontal axes) must be fastened in
such a manner to prevent them from being separated or sheared off due to the
delay. The max. delay must be calculated. The calculation of the fastening and
loading of the attachments must also be taken into account in the construction.
Workplaces and operating devices in the direction of travel
should be avoided as far as possible.

10 3/d It must be ensured that when
the enable button is not
pressed, no persons can be
endangered by falling vertical
axes, telescope axes or
workpieces.
Grippers must remain in the de-energized state in clamping position.
To minimize risk, vertical axes can be redundantly equipped with an additional
brake.
Telescope axes and counter balances: Special attention is required here. The axis
(for a telescope axis, the 2nd stage) is to be secured with a mechanism. Operation
in setup mode only when the restricted area is closed off.
Do not walk under suspended workpieces or vertical axes. Take
special care with telescope axes. Inspect belts visually for cracks
and tears before every setup procedure.
