When using the internal hexagon socket to fit a self-configured second drive
output shaft (on a DSM with spigot shaft):
5. Make sure that the second drive shaft
cannot slide out of the internal
hexagon socket aJ (Fig. 6).
This is ensured by the thread (A) at the
base of the internal hexagon socket.
A fastening screw can be fitted here.
For this, the second drive shaft must
be hollow.
6. When mounting the moveable mass,
make sure that the following
specifications are fulfilled (Fig. 7):
– it must not be tilted,
– permissible radial force Fz,
– permissible axial force Fx,
– permissible mass moment of inertia
(
Technical data).
The mass moment of inertia of the moving mass should be calculated. Lever arms,
cantilever arms and masses on a second drive shaft should be taken into account
in the calculation. The permissible mass moment of inertia (
specifications) depends on the specific situation:
– nominal dimensions of the DSM
– type of end-position cushioning

• Push the moveable mass onto the drive output shaft (spigot shaft/flange
shaft/rotating plate) (Fig. 9).
• Make sure that the moveable mass cannot slide down from the drive output
shaft. This is ensured by the threads in the drive output shaft. When tightening
the screws (Fig. 10), lock them at the hexagonal fitting bolt aJ.

7. Adjust the stops of the end positions statically according to the type.
4.2 DSM without stop system
Note
Operating the DSM without shock absorbers will destroy the drive. A DSM
without a stop system has no shock absorbers.
• Make sure that the DSM is always operated with shock absorbers (internal or
external).

Shock absorber retainers (Fig. 11) for retrofitting an internal shock absorber can
be ordered separately and installed on the DSM subsequently (

When external stops and shock absorbers are used:
• Make sure that the following points
(A)
are observed (Fig. 12):
– point of impact in the mass
moment of inertia (important for
eccentric masses on the lever arm)
aJ
– max. permissible stop force and
min. stop radius r

– use of protective devices

4.3 Adjusting the DSM with an internal stop system
Note
Operating the DSM without shock absorbers will destroy the DSM.
1. Remove the cover cap of the DSM from the housing (if present).
2. Screw the shock absorber elements (elastomer shock absorbers or shock
absorbers) into the shock absorber retainer.
Observe the enclosed documentation.
3. Swivel the moveable mass to the desired end position:
– manually
– with hexagon spanner on swivel lever aJ.
The angle scale can be used for precise positioning (Fig. 13).

4. Unscrew the locking screws for the
shock absorber retainers (Fig. 14). To
0.4
shift the shock absorber retainers, it
is sufficient to slacken the locking
screws until they can just barely be
shifted.
5. If possible use symmetric angle
settings that follow line of symmetry
M of the DSM (Fig. 15). These
produce a more even movement
between right-hand and left-hand
swivelling movements.
6. Push the shock absorber retainer
including shock absorber (elastomer
shock absorber or shock absorber)
towards the stop lever. When doing
so, the cushioning stroke must be
63
pushed down until the sleeve of the
shock absorber is against the stop
level (Fig. 16).

If necessary, use the hexagonal
25
fitting bolt to apply counter force.
25
Note
Shock absorber retainers that are fastened with an insufficient tightening torque
may shift under operating conditions, resulting in destruction of the DSM.
7. Tighten the locking screw of the
shock absorber retainer (Fig. 17)
again with the following tightening
torque (Fig. 18).
Only with the specified tightening
torque will the gearing of the shock
absorber retainer grip the housing
material.
