•The rod lock may only be triggered and unlocked when the
product has been shut down.
•See the data on static holding force in the catalog. The forces
occurring in a clamped condition must not exceed the holding
force.
•In the event of a dynamic load or overload (e.g. drop in
pressure during movement), the clamping cartridge must be
checked and replaced if necessary.
WARNING
The Rod lock is not a safety component for personal protection
in accordance with the Machinery Directive.

recycling or proper disposal.
2.12 Fundamental dangers
General
• Observe safety distances.
• Never deactivate safety devices.
• 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.
• 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.

2.12.2 Protection during commissioning and operation
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.
2.12.3 Protection against dangerous movements
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 re-
mains 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.

If the module moves too hard against the end positions, the
linear module might be damaged.
•A linear movement alway must reach the end position without
jerk or bounce.
•Therefore flow control valves and shock absorbers must be
used, Setting the speed [}19] and Adjustment of the shock
absorber strocke [}20].
•Please observe the diagrams and information in the catalog
pages.
NOTE
• Use connecting wires with the same or a larger cross-section as
the connection thread.
• Observe the air supply requirementsTechnical Data [}15].

4.3 Setting the speed
NOTICE
Risk of damage to the product!
If the end position is approached too hard, the product may be
damaged.
•Adjust exhaust throttle valve and shock absorber so that the
movement is braked smoothly.
ØClose exhaust throttle valve completely.
ØOpen exhaust throttle valve until the product starts to move.
ØContinue to open the exhaust throttle valve incrementally until
the movement decelerates smoothly.
✓If the speed is too low, the product will brake too soon and
the end position will be reached too slowly.
✓If the speed is too high, the product will impact against the
end position and the shock absorber will be overloaded.
NOTE
A smooth motion may also be too slow in many use-cases.
Further settings can be made via the shock absorbers, Adjustment
of the shock absorber strocke [}20].
