Basic safety notes
Intended use
The module was designed to swivel permissible attachments or
workpieces.
The module is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The module may be used only in the context of its defined applica-
tion parameters (6, Page 11).
The module is intended for industrial use.
To use this unit as intended, it is also essential to observe the
technical data and installation and operation notes in this manual
and to comply with the maintenance intervals.
Not intended use
It is not an intended use if the module is used, for example, as a
pressing tool, stamping tool, lifting gear, guide for tools, cutting
tool, clamping device or a drilling tool.
Environmental and operating conditions
•The module may be used only within its defined application pa-
rameters.
•Ensure that the environment is clean. Observe the lubrication
intervals (10.2, Page 32).
•Ensure that the environment is free of splashing water and va-
pors, and also of abrasive dust and process dust. This does not
apply to modules designed especially for unclean environ-
ments.
•Do not subject the module to excessive vibrations and/or me-
chanical shocks.

1 Set cycle ring to zero point position. Marking groove on the
cycle ring is in agreement with the marking holes in the
switching plate and bearing ring (☞arrows).
2 Remove the cap from the connection thread.
3 Screw sensor (1) into the thread until the signal is present at
the output.
4 Lock sensor into place with a counter-nut.
MMS sensor attachment
NOTICE
Risk of damage to the sensor during assembly!
•Observe a maximum tightening torque of 10 Ncm for the set-
screws.
Fig. 6 MMS sensor attachment
For monitoring of the two end positions of the piston, one sensor
each is installed.
1 Turn sensor (2) into the groove (1 - 4).
2 Pressurize piston at connection A or B to ensure that it is in
end position (7.2, Page 15).
3 Adjust the sensor (2) to piston position and lock into place us-
ing an Allen key.
4 If need be, repeat the procedure with the second sensor and
the opposing piston position.

Setting the swiveling time
See the catalog data for data on the swiveling time.
The swiveling time is ideally set with exhaust air throttles.
These must be provided by the customer (7.2, Page 15).
Setting the end position dampers
In the version for left-hand and right-hand operation (L / R), a hy-
draulic shock absorber is installed in the lifting stroke and an elas-
tomer damper for dampening the reverse stroke.
In the version for operation on both sides, 2 shock absorbers are
installed.
Fig. 7 End position dampers setting; e.g. RST-P...-R
NOTICE
Back stop (17) and dampers (45) do not serve as end stop for the
drive, but only for dampening.
The drive piston must stop at the respective end plate, otherwise
the module cannot lock correctly and continue pulsing.
•Always set back the back stop (17) and dampers (45) to the
extent that the module performs the full angle stroke (90°,
60°, 45° or 30°) and can be pulsed on.

The load occurring during operation is mounted onto the mod-
ule.
The permissible swiveling time (☞catalog data) is set.
NOTE
If the counter-plate is loosened, compressed air can escape to a
small extent.
1 Slightly undo the screws (51) to undo the counter-plate (15).
2 Turn the dampers to the desired position.
3 Tighten screws (51).
4 Test dampening during operation, correct swiveling time if ne-
cessary and readjust the setting of the dampers.
The damper is set correctly if the device reaches its end posi-
tion swiftly without any mechanical impact.
The dampening of the reverse stroke through the elastomer
damper in the back stop (17) in versions L / R is set indepen-
dently of the load and swiveling time.
NOTE
If the counter-plate is loosened, compressed air can escape to a
small extent.
1 Slightly undo the screws (51) to undo the counter-plate (15).
2 Turn the back stop (17) to the desired position.
3 Tighten screws (51).
4 Check the dampening in operation and correct the setting if
necessary.

Handling and operation
Start-up
Measures for start-up
1 Check the technical specifications (6, Page 11).
2 Do not use the module until trouble-free operation has been
checked taking all permissible operating parameters into ac-
count.
3 The swiveling time is ideally regulated via throttle check valves
(7.2, Page 15). The speed is always set so that it starts at a
low speed and increases to a higher speed until the desired
operating speed has been reached.
Starting up the module
1 Connect all power lines (compressed air) (7.2, Page 15).
2 Setting the swiveling time (7.4, Page 18).
3 Setting the end position dampers (7.5, Page 18).
4 Test run as per actuation (8.2, Page 21).
5 Correct settings, if necessary.
