Intended use
2.1
The product was designed to swivel permissible attachments or
workpieces.
For use with the robot for applications with endless movement
and feed-through of electrical signals and pneumatics
The product is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The product may be used only in the context of its defined applica-
tion parameters ( 5
, Page 14).
The product is designed for industrial use.
To use this unit as intended, it is also essential to observe the

Notes on particular risks
2.7
Generally valid:
• Remove the energy supplies before installation, modification,
maintenance, or adjustment work.
• Make sure that no residual energy remains in the system.
• Do not move parts by hand when the energy supply is connected.
• Do not reach into the open mechanism or the movement area
of the unit.
• Perform maintenance, modifications, and additions outside the
danger zone.
• Secure the product during all operations against uncontrolled
activation.
• Take a precautionary approach by maintenance and disassembly.
• Only specially trained staff should disassemble the product.

Basic safety notes
www.comoso.com
WARNING
Risk of injury from objects falling and being ejected
• The danger zone must be surrounded by a safety fence during
operation.
WARNING
Risk of injury when the machine/system moves unexpectedly
due to failure of the energy supply or malfunction of the controller.
WARNING
Risk of injury due to rotating components!
Avoidance: The danger zone must be surrounded by a safety
fence during operation.
WARNING
Risk of injury due to loosened parts and destruction of the swivelling unit due to damaged shock absorbers!
Avoidance: Regular inspection of the individual components on
wear and damage.
WARNING
Note that suitable emergency-off strategies (e.g. controlled shut
down) and restarting strategies (e.g. pressure build-up valves,
appropriate valve switching sequences) are needed for all
pneumatic actuators.
Cutting off the pressure in an uncontrolled manner could lead to
undefined states and behavior.

Sensors
The module is prepared for the use of the sensors IN 80 and MMS
22.
1 For modules with an explosion-protected design (EX), the sup-
plementary sheet "Installation and operation notes - EX"
included in delivery must also be observed.
2 If you require further information on sensor operation, con-
tact your SCHUNK contact person or download information
from our homepage.
3 Technical data of the sensors are contained in the data sheets
(included in the scope of delivery).

We recommend the use of four magnetic switches to monitor the
www.comoso.com
6.4.1
Magnetic switch MMS 22
The magnetic switches can be mounted via four grooves in the
module housing. The setting of the switching positions
must be done as follows:
1 Turn the unit to the required swivel angle.
2 Push the magnetic switch into the groove.
3 Move the magnetic switch along the groove until it actuates.
4 Secure the magnetic switch. (see enclosed data sheet)
5 Check the switch position of the magnetic switch by swiveling
the module repeatedly.

Inductive proximity switch IN 80
Fig. 10 Connection example for IN 80
1 brown 2 black 3 blue
The inductive proximity switches used are equipped with reverse
polarity protection and are short-circuit-proof.
Make sure that you handle the proximity switches properly:
26 01.05|SRU-plus EDF 20 - 60|en
www.comoso.com
Assembly
• Do not pull on the cable.
• Do not allow the sensor to dangle from the cable.
• Do not overtighten the mounting screw or mounting clip.
• Please adhere to the permitted bend radius of the cable.
(☞ catalog)
• Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and sulphuric acid.
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or electromagnetic fields.
• Check to make sure that the cable is fastened and installed correctly. Provide for sufficient clearance to sources of
high-frequency interference and their supply cables.
• Parallel switching of several sensor outputs of the same type
(npn, pnp) is permissible, but does not increase the permissible
load current.
• Note that the leakage current of the individual sensors
(ca. 2 mA) is cumulative.

3 Tighten the hexagon socket screw (7) until the clamping sleeve
(6) no longer turns. The hexagon socket screw (7) grips the
clamping sleeve (6) and simultaneously secures the bracket (5)
on the rotary actuator.
4 The switching distance has now been set: Tighten the clamp-
