Installation instructions
Before installation and use check whether the identification
number on the damper or on the packaging matches the
respective designation on the delivery note. Profile dampers are
maintenance-free and ready to install.
Operating temperature range:
-40 °C to +90 °C
Temperature effect:
The W
3
values given in the performance
table are valid for room temperature in the environment. At higher
temperatures the energy capacity per stroke is reduced.
Mounting:
in any position, however, always in such a way that
the impact surface of the profile damper is evenly loaded. A side
load angle between profile damper and occurring mass is to be
avoided as transverse forces can lead to tearing off or permanent
deformation of the damper.
The outer diameter of the damper increases upon impact. Note
the max. compressed diameter (d
1
) listed in the table. The moving
mass should have at least the same diameter so that the entire
impact surface is loaded.
Mounting information:
To mount the damper we recommend
the use of original ACE mounting screws. The listed maximum
torque is to be observed. Please also check the thread length (L
M
)
along with all further dimensions listed in the table.
Permissible torque of mounting screw:
M5: 3 Nm
M8: 20 Nm
M16: 40 Nm (DIN912)
M16: 120 Nm (collar bolt)
Note:
For seawater applications please use stainless steel bolts
– these are not included.
Packaging disposal
Please dispose of the transportation packaging in an environ-
mentally-friendly manner. Recycling packaging materials saves
raw materials and reduces waste. The packaging materials do not
contain any prohibited materials.
WARNING
A failure of the product can lead to personal injuries and/or
material damage. Use additional safety elements.
During installation/disassembly of the profile dampers,
moving masses can lead to injuries due to inadvertent
starting. Secure moving masses against inadvertent
moving.
The profile dampers may be unsuitable for use and
have an insufficient damping effect. Before installation
check the correct size of the dampers using the field
data, performance table (page 4) and calculations. The
energy capacity per stroke during continuous duty and for
emergency stop applications may not be exceeded (see
performance table).
The profile damper can tear off upon impact. Always lay out
the connection structure in such a way that the maximum
occurring forces can be absorbed with sufficient safety.
The maximum reacting forces Q listed in the calculations
may deviate from the actually occurring reacting forces, as
these are based on theoretical values.
The profile dampers may be unsuitable for use as a
rebound effect can occur. Note that the moving mass is
not accurately braked and the energy is not completely
absorbed. A limited application range is therefore to be
observed for the following drive types: toothed belt drive,
threaded spindle drive, drive with gears. The maximum
return forces listed in the calculations may deviate from
the actually occurring return forces, as these are based on
theoretical values.
Exceeding or falling below the maximum or minimum
temperature can lead to the destruction of the damper
material and the profile damper could lose its function.
Maintain the operating temperature range of -40 °C to
+90 °C.
Fluids or aggressive media in the surrounding area can
attack or destroy the material of the profile damper and
cause it to fail. Insulate the "external materials" in the area
around the profile damper. Note the chemical resistance
list.
Impact velocity that is too high can lead to damage to
the profile damper and failure. Note the maximum impact
velocity of 5 m/s.
The profile dampers for emergency stop may be unsuitable
for continued use after one impact. Profile dampers
that are not regularly operated (e.g. for emergency stop
devices) are to be checked after a damper impact.
Damage to the surface by other external influences
can lead to an insufficient damping and to a premature
failure of the profile damper. We recommend regularly
checking the surface for cracks and deformations as well
as checking the mounting elements are properly secured.
Check emergency stop devices at least once per year and,
in the case of continuous duty, at intervals of a maximum
of three months.
Please mount the dampers in such a way that there is
sufficient room for the max. compressed external diameter.
The moving mass should have at least the same diameter
so that it does not buckle or crack.
