• Before commissioning the product, take appropriate protective
measures to secure the danger zone.
• Disconnect power sources before installation, modification,
maintenance, or calibration. Ensure that no residual energy
remains in the system.
Basic safety notes
•
If the energy supply is connected, do not move any parts by hand.
• Do not reach into the open mechanism or movement area of
the product during operation.

Basic safety notes
2.12.2 Protection during commissioning and operation
2.12.3 Protection against dangerous movements
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
•
Take appropriate protective measures to secure the danger zone.
• Never step into the danger zone during operation.
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.

2.12.4 Protection against electric shock
Possible electrostatic energy
Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
• The operator must ensure that all components and assembly
groups are included in the local potential equalisation in
accordance with the applicable regulations.
• While paying attention to the actual conditions of the working
environment, the potential equalisation must be implemented
by a specialist electrician according to the applicable
regulations.
• The effectiveness of the potential equalisation must be verified
by executing regular safety measurements.
2.13 Notes on particular risks
Basic safety notes
WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
• Before starting any work on the product: Switch off the power
supply and secure against restarting.
• Make sure, that no residual energy remains in the system.
WARNING
Risk of injury from objects falling and being ejected!
Falling and ejected objects during operation can lead to serious
injury or death.
• Take appropriate protective measures to secure the danger
zone.
WARNING
Risk of injury from rotating components!
In the case of swivel units or rotary tables with a rotary drive,
serious injuries can be caused by rotating components.
• Take appropriate protective measures to secure the danger
zone.

suitable for swivel tasks up to 180°.
• The swivel angle is flexibly adjustable (between 0° and 180°).
The end positions of the swivel angle are roughly adjusted via
balls. For fine adjustment the variable end position dampers are
used.
• The speed can be controlled via external throttle check valves
(exhaust air throttles).

5.1 Assembling and connecting
DANGER
Danger of explosion in potentially explosive areas!
• Observe supplementary sheet for products with explosion-
resistant versions "SFL -...-EX".
WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
• Before starting any work on the product: Switch off the power
supply and secure against restarting.
Assembly
• Make sure, that no residual energy remains in the system.
NOTICE
Material damage due to faulty settings and assembly.
If the end position is approached too aprubtly, the product may
be damaged.
• Ensure the turning / swiveling movement is carried out
without bouncing or bumping.
• Therefore provide sufficient throttling and damping.
• Please observe the information in the catalog data sheet.
NOTE
• Observe the requirements for the compressed air supply,
Technical data [}14].
• In case of compressed air loss (cutting off the energy line), the
components lose their dynamic effects and do not remain in a
secure position. However, the use of a SDV-P pressure
maintenance valve is recommended in this case in order to
maintain the dynamic effect for some time. Product variants
are also offered with mechanical gripping force via springs,
which also ensure a minimum clamping force in the event of a
pressure drop.

process reliability of the magnetic switch monitoring.
• For process-reliable monitoring, the adapter plates and the
attachments in the closer surrounding of the swivel unit
should be made of non-ferromagnetic material.

5.3 Checking opening and closing intervals
If the gripper does not achieve the opening and closing times
specified in our latest catalog, check the following points:
• Are the throttle valve connections at the sviwel unit opened as
far as possible? The movement must be carried out without
bumping and bouncing.
• Do the compressed air lines to the swivel unit have a sufficient
inner diameter regarding the compressed air consumption?
• Are the compressed air lines between the swivel unit and the
valve as short as possible?
• Is the flow rate of the directional control valve sufficient for the
swivel unit's compressed air consumption?
If the movement times in the application determined by SCHUNK
are not reached despite optimal compressed air connections,
SCHUNK recommends using quick exhaust valves directly at the
swivel unit.

5.4 Adjusting the swivel angle
By inserting or removing balls in/from a ball guide rail, the range of
the swivel angle can be roughly adjusted between 0° and 180° or
0° and 90°.
Adjust the end position dampers (shock absorbers for S-variant or
elastomer for E-variant) in order to fine tune the end positions of
the swivel angle range.

6.1 Product does not achieve the opening and closing times
Possible cause Corrective action
Compressed air lines are not
installed optimally.
Loading too large. Check permissible weight and length of the gripper
If present: Open the flow control couplings on the
product to the maximum that the movement of the
jaws occurs without bouncing and hitting.
Check compressed air lines.
Inner diameters of compressed air lines are of suffi-
cient size in relation to compressed air consumption.
Keep compressed air lines between the product and
directional control valve as short as possible.
Flow rate of valve is sufficiently large relative to the
