Combined installation

The direction stability of connected bellows actuators is not guaranteed.

•Incaseofcombined

installation of two or

more bellows actuators,

make sure that the

resistance to bending is

secured through

suitable design

measures.

Fig. 7

To attach the bellows actuator:

• Tighten the connectors alternately and, if necessary, diagonally opposite with a

torque spanner (tightening torque  10 Technical data).

5.2 Installation, pneumatic

3. Connect the bellows actuator EB via the pneumatic port 1.

To set the stroke speed:

• Screw a one-way flow control valve into the compressed air supply port.

6 Commissioning

Warning

Damage to the bellows actuator.

• Place the bellows actuator under pressure only with height stop.

• Make sure that the maximum operating pressure of 8 bar is not exceeded.

6.1 Preparation for commissioning

Warning

Injury to people, damage to the machine and system.

• Makesurethat,inthetravelrange,

– nobody c an reach into t he path of the movable components (e.g. by provid-

ing a protective guard)

– there are no foreign objects.

rest.

6.2 Commissioning the complete system

• Slowly pressurize the system as a whole.

In this way you will prevent sudden uncontrolled movements.

7 Maintenance and care

• Check the bellows ac tuator regularly for cracks, bubbles, brittleness or other

external damage. Replace the bellows actuator, if necessary.

7.1 Cleaning

1. When necessary, clean the bellows ac tuator with a soft cloth and one of the

following cleansers:

– commercially available alkaline cleaners

– diluted caustic soda

– water with ammonia.

2. Then rinse the cleanser away with clear water.

Note

• Avoid the use o f cleansers based on aliphatic or aromatic hydrocarbons, such

as kerosene, cleaning benzine, benzole, cellulose thinner, etc.

• Alternatively, use a steam jet or high-pressure cleaner.

– maximum pressure: 90 bar

– minimum distance: 20 cm
