The unit must only be used within the scope of its technical data. Appropriate use also includes

compliance with the conditions the manufacturer has specified for commissioning, assembly,

operation, the environment and maintenance. Using the unit with disregard to even a minor

specification will be deemed inappropriate use. The manufacturer assumes no liability for any

injury or damage resulting from inappropriate use.

1.3.Safety notes

There are potential risks associated with the unit, for example if:

the unit is improperly used, installed or serviced.

the unit is used other than for the intended purpose.

the EC Machine Directive, the accident prevention regulations, the VDE guidelines or the

safety and installation instructions are not observed.

All personnel who are responsible for installation, commissioning and servicing must have

read and understood the entire operating manual, in particular the chapter on »Safety«. It is

recommended to have this confirmed in writing.

Installation and dismantling, mounting of the proximity switches, connections and

commissioning may be carried out only by authorized personnel.

Work procedures that impair the correct functioning and operational safety of the product

are prohibited.

Do not move any parts by hand when the unit is connected to the power supply.

Do not reach into the open mechanical parts and the area of motion of the rotary unit.

The power supply cables must be removed for assembly, modification, maintenance and

adjustment of the unit.

Carry out all maintenance, modifications or attachments outside of the danger zone.

During installation, connection, adjusting, commissioning and testing, measures must be

taken to prevent the risk of inadvertent activation of the unit by the fitter or other persons.

Protective covers must be provided for the use of all handling modules in accordance with

EC Machine Directive, Section 1.4.

There is a danger due to falling or ejected objects. Preventive measures must be

taken to prevent the falling or ejection of potentially dangerous objects (machined

workpieces, tools, chips, debris, waste, etc.).

Additional bore holes, threads or attachments not offered by SCHUNK as accessories may

be mounted only after obtaining the approval of SCHUNK.

Rotary units with internal springs can have parts that are under spring tension. Therefore,

special care is necessary when dismantling such a unit.

In the event of emergency shut-down the rotary unit can still move due to a drop in

pressure. If such movement is not desired, the position of the unit in the event of

emergency shut-down can be secured in any end position with the use of SCHUNK SDV-P

valves.

In addition, the applicable safety regulations and accident prevention regulations must be

observed.

2. Warranty

The warranty period is 24 months after delivery date from the factory, provided that the

specified maintenance and lubrication intervals were observed. Components coming into

contact with workpieces and wearing parts are never included in the warranty. In this context,

please also see our General Terms and Conditions.

5. Assembly and installation

5.1.Installation of the electrical cable feed-through in the SRU rotary actuator

You require these instructions only if you would like to retrofit an EDF on an existing SRU unit.

SRU units can already be ordered equipped with EDF ex-works.

1. Feed the cable through the hole in the flat seal and position it in the recess in the distributor

plate.

2. Screw the thread reducer (item 7) into the pinion in the thread below the flat recess and

secure with Weicon 302-22. (Not for EDF for SRU20/25)

3. In order to position the distributor plate, place the two corresponding guide sleeves in the flat

recesses.

4. Pull the cable through the center bore of the SRU rotary actuator until the distributor plate is

just in front of the pinion.

5. Place the O-rings in the recesses of the air feed-throughs in the pinion.

6. Pull the cable through fully and position the distributor plate correctly on the pinion.

IMPORTANT

Damage to the cable connection of the adapter plate is possible!

–Do not pull on the cable too strongly!

7. Now fasten the distributor plate on the pinion with the two screws (item 28).

8. Check the tightness of the air feed-throughs.

9. Turn the rotary actuator and place it on the distributor plate.

10. Swivel the SRU counter-clockwise up to the stop.

11. Knock the clamping pins into the bores on the pinion.

12. Pull the cable end through the bore in the flange.

13. Solder the cable onto the flange connector (item 22) in accordance with specifications

(see chapter 5.2).

14. Align the cable spiral and shape into original form. Spiral diameter approx. 27 mm.

15. Using a paint brush, grease the flange (inside) and the cable spiral with milk fat.

16. Place the cable in the clamping groove in the flange.

17. Fit the O-ring (item 47) at the connector flange.

18. Screw the connector onto the cover plate.

19. Screw the cover plate onto the flange with the oval head screws.

20. Fasten the flange on the SRU with two screws and secure with Weicon 302-22

21. Place the O-ring (item 43) in the MDF media feed-through flange.

22. Fasten the cover plate (item 6) on the flange with 2 countersunk screws.

Disassembly is carried out in reverse order.
