2 Function and application
When the compressed air ports are pressurised alternately, the inner vane in
the housing swivels backwards and forwards. This swivel movement is transmitted
to the outer stop lever and the drive shaft as a rotary movement. The angle of
rotation can be limited by means of adjustable stops and adjustment sleeves for
the stop lever. To use the DSMI as a measuring cylinder, the adjustment sleeve in
the shock absorber retainer can be replaced with cushioning components
(elastomer shock absorbers or shock absorbers).
The pneumatic DSMI swivel module was designed for rotating or swiveling work
loads which do not have to carry out a complete revolution.
The integrated measuring system was designed for monitoring the swivel position
in combination with a positioning controller from Festo (e.g. CMPX, CMAX,
SPC200, SPC11 “Soft Stop”) or for use as a measuring cylinder.
If it is used as a measuring cylinder, the compressed air will need to be throttled
(e.g. using one-way flow control valves).
The device is intended for use in an industrial environment.
3 Transport and storage
 Take the weight of the DSMI into account:
It weighs up to 7 kg.
 Ensure the following storage conditions:
– Storage times should be kept to a minimum
– Cool, dry and shaded storage locations protected from corrosion.

4 Safety conditions
For electronically closed-loop control of the DSMI in combination with a
positioning controller:
Note
Special conditions apply to the electronic regulation of the DSMI.
 Note the warnings and instructions in the descriptions of the positioning
controller.
The following applies to all applications:
Note
Malfunctions will occur if the device is not used correctly.
 Make sure that the specifications in this chapter are always observed.
 Compare the limit values specified in these operating instructions with your
actual application (e.g. pressures, forces, torques, temperatures, masses).
The product can only be operated in accordance with the relevant safety
guidelines if the maximum load limits are observed.
 Take the ambient conditions at the location of use into account.
Corrosive environments (e.g. ozone) will reduce the service life of the product.
 Make sure that the compressed air is properly prepared (èTechnical data).
 Maintain the selected medium for the complete service life of the product.
Example: Always use non-lubricated compressed air.
 Pressurise your entire system slowly. There will then be no uncontrolled
movements.
For slow start-up pressurisation, use the HEL pressure build-up.
 Please comply with national and local safety laws and regulations.
 Remove all transport packaging such as foils, caps and cartons
(except for any plugs in the pneumatic connections).
The packaging is intended for recycling on the basis of its constituent
materials (exception: oiled paper = other waste).

 Unauthorised product modification is not permitted.
 Note the warnings and instructions on the product and in the relevant
operating instructions.
 Take the tolerance of the tightening torques into account. Without special
specification, the tolerance is ±20 %.
5 Installation
Mechanical installation
For electronically closed-loop control of the DSMI in combination with a position
ing controller:
Note
Special installation specifications apply to the electronically controlled
operation.
 To install the mechanical system, please observe the instructions in the
descriptions of the positioning controller.
The following applies to all applications:
 Handle the DSMI with care so that the drive shaft is not damaged. This applies
in particular to the following:
 Check whether it is necessary to drill
additional holes in the mounting flange
of the DSMI.
The grey areas (G) in the drawing show
where additional holes can be drilled on
the DSMI (e.g. to mount centring pins).
 Position the DSMI so that you can easily reach the operating parts.
 Fasten the DSMI with at least 2 screws.

When using the hexagon socket to fit a self-configured
second drive shaft:
 Make sure that the second drive shaft
cannot slide out of the hexagon socket 9.
This is ensured by the thread (A) at the
base of the hexagon socket. A fixing screw
can be fitted in this case. For this, the
second drive shaft must be hollow.
 When placing the moving mass, make
sure that the following specifications are
fulfilled (è“Technical data” and
“Characteristic curves” chapters):
– It must not be tilted,
– Permissible radial force Fz,
– Permissible axial force Fx,
– Permissible mass moment of inertia.
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
(èCatalogue specifications) depends on the specific situation:
– Nominal size of the DSMI
– Type of end-position cushioning
– Swivel time
– Swivel angle
It can be taken from the catalogue data or the description of the positioning
controller.

To fasten the work load:
1. Push the moving mass on to the drive shaft.
2. Make sure that the moving mass cannot
slide off the drive shaft. This is ensured by
the thread in the drive shaft. When
tightening the screws, lock them at the
hexagon socket 9.

 Adjust the stops of the end positions statically according to the type.
 If possible, use symmetric angle settings
that follow the line of symmetry of the
DSMI.
These produce a more even movement
between right-hand and left-hand swivel
ing movements.
Adjusting the stops on the DSMI
Note
Operating the DSMI without cushioning will destroy it.
 Make sure that the DSMI is always only operated with shock absorbers
(electronically controlled, internal or external).
 Make sure that the locking screws aB of the shock absorber retainers are
retightened with the specified tightening torque.
 Observe the instructions in the descriptions of the positioning controller
when adjusting the stops.
For use as a measuring cylinder:
 Replace the adjustment sleeves with cushioning elements
(elastomer shock absorbers or shock absorbers è“Accessories” chapter).
Observe the enclosed documentation.

1. Remove the cover cap of the DSMI from the housing (if present).
2. Swivel the moving mass to the desired
end position.
If the DSMI is depressurised, this can be
done by hand or using a hexagon spanner
on the swivel lever aA.
The angle scale can be used for precise
positioning.

3. Unscrew the locking screws aB for the
shock absorber retainers. To shift the
shock absorber retainers, it is sufficient to
slacken the locking screws until they can
just barely be shifted.
4. Push the shock absorber retainer towards
the stop lever until the adjustment sleeve
or the fixed stop of the shock absorber
(elastomer shock absorber or shock
absorber) touches the stop lever.
5. Retighten the locking screw aB of the
shock absorber retainer with the following
tightening torque.
Only with the specified tightening torque
will the gearing of the shock absorber
retainer grip the housing material.
