Safety instructions related to the product and technology

DANGER
Danger of explosion while operating in explosive atmospheres!
If the system in which the product is to be installed is located in an explosive atmosphere, it may ignite during operation.

1. Always comply with local installation regulations.
2. Carry out tasks in non-explosive atmospheres only with a fire permit for these tasks. Use only non-sparking tools if you still need to deal with the presence of an explosive atmosphere.

DANGER
Danger of explosion due to electrostatic charge!
Electrostatic charging on the product can cause sparks to form and presents an explosion hazard in explosion protection zones.

• Avoid electrostatic charging, e.g. by grounding the product.

DANGER
Spark formation due to mechanical loads!
Mechanical loads lead to the formation of sparks and present an explosion hazard.

1. Never twist or bend the cylinder, or mount it when it is under tension.
2. Never expose the cylinder to impacts during transportation, assembly, or operation.
3. Install the cylinder so that it is protected from the energy of external impacts to the housing that can occur during operation.

DANGER
Danger of explosion due to spark formation!
Some piston rod attachments and mounting elements permit oscillating rotary or swivel movements of the cylinders. The use of these elements as a radial friction bearing with circumferential speeds above 1 m/s leads to impermissible heating. Overheating can cause friction sparks, which present an explosion hazard.

• Make sure that the circumferential speed on the friction surfaces does not exceed 1 m/s.

CAUTION
Improperly installed compressed air lines!
Danger of injury!

• Lay the compressed air lines so that no one can trip over them.

CAUTION
Falling useful load!

With a vertical installation position of the cylinder, a suspended load can fall when the compressed air supply is switched off.

• Always secure the area below a suspended load.

Assembly

DANGER
Danger of explosion through overheating!
The product generates heat during operation. Incorrect installation can cause the product to overheat.

1. Ensure sufficient distance to adjacent components to permit adequate air circulation around the product.
2. Shield the product if it is installed near heat sources.

DANGER
Danger of explosion if not grounded!
Compensation and residual currents could increase the temperature of the components and possibly generate sparks.

1. Ground the housing and the piston rod so they are electroconductive with the system.
2. Ground the system in accordance with the applicable regulations.

DANGER
Danger of explosion due to electrostatic charge on the tubing surface!
Large tubing diameters increase the risk of an electrostatic charge on the tubing surface. Electrostatic discharge can lead to explosions.

• Only use tubing with the following external diameters to connect the cylinders: Cylinder Ø up to 25 mm: max. 6 mm
  Cylinder Ø 32 mm or above: any

DANGER
Danger of explosion due to impermissible tubing!
Long tubing often overheats during operation. Overheated tubing can lead to explosions.

• Use the following tubing lengths:
  Cylinder Ø up to 25 mm: max. 5 m
  Cylinder Ø 32 mm or above: max. 10 m

DANGER
Danger of explosion due to dust clouds!
Dust clouds can lead to explosions.

• Make sure that the compressed air and exhaust are either evacuated from the dust protection area through tubing lines or that the exhaust lines are mounted to permit the continuous controlled exit of penetrating dust.

DANGER
Danger of explosion due to circulating currents!
Stray magnetic fields may cause circulating currents, e.g. near electrical drives with asymmetrical loads, during arc welding, if the ground is conducted via the system and not via a 0 V line, or if there is cathodic corrosion protection.

• Make sure that there is protection against the possible effects of circulating currents, e.g. by grounding the product.

NOTICE
Open pneumatic connections!
Contamination of the cylinder interior!

• Only remove the blanking plugs just before connecting the tubing.

NOTICE
Incorrect cylinder mounting!
Cylinder damage!

1. Make sure that the cylinder and accessory parts are properly installed.
2. Observe the maximum tightening torque values and check that all screws and bolts are properly tightened.

Installation conditions

The cylinder has a lifetime lubrication.

• The preferred medium is oil-free compressed air. Compressed air quality: see “Technical Data”.

Assembling the cylinder

1. Make sure that all relevant system parts are not under voltage or pressure before mounting the cylinder. Protect the system against being restarted.
   Depending on your configuration, you can mount the product in different ways. The content of delivery only includes the mounting you selected in the configurator.

   • You can find the exact dimensions of the mountings for your cylinder in the online catalog.
   • Install the cylinder in your system so the pneumatic connections and, if present, throttle screws for the cushioning are always accessible.

2. Fix the cylinder on the bracket in your system part so that it is not under tension. Observe the maximum permissible tightening torque values listed in the online catalog. General technical standards apply if no information is given or if you use your own mounting materials.

3. Remove the blanking plugs at the pneumatic connections.

4. Make the pneumatic connections for the cylinder. You can find the pneumatic connection technology for cylinder tubing in the online catalog.

5. Mount the useful load onto the piston rod. Depending on the configuration, you can mount the useful load onto the internal or external thread. Observe the permissible piston forces.
   You can find the maximum possible piston forces in the online catalog.

On double-acting cylinders, the effective piston surface and piston force are lower during retraction than extension due to the cylinder piston rod. This does not apply to cylinders with a through piston rod.

Commissioning

DANGER
Danger of explosion due to heat generation! The cylinder generates heat during operation. Explosion protection is no longer guaranteed when specified limits are exceeded.

• Observe the limits specified under “Technical Data” and on the rating plates.

DANGER
Danger of explosion due to excessive operating frequencies and piston speeds!
Excessive operating frequencies and piston speeds overheat the cylinder and present an explosion hazard.

1. Never exceed the maximum permissible double-stroke frequency:
   Cylinder Ø up to 25 mm: 0.33 Hz
   Cylinder Ø 32 mm or above: 0.4 Hz

2. Never exceed the maximum piston speed of 1 m/s.

CAUTION
Danger of burns caused by hot surfaces!
Touching the surfaces of the product during operation could cause burns.

1. Let the product cool off before working on it.
2. Do not touch the product during operation.

CAUTION
Danger due to noise!
Hearing damage due to exhaust and impact noise

• Correctly adjust the cushioning.

CAUTION
Danger due to sudden escaping of compressed air!
Uncontrolled piston rod movement!

1. Ensure that no one can reach into the system’s work area and that no objects can penetrate it.
2. If necessary, assemble a protective barrier.
3. Slowly pressurize the system to the stipulated working pressure.

Setting the speed

DANGER
Danger of explosion due to heat generation!
Excessive piston speeds overheat the cylinder and present an explosion hazard.

• Never exceed the maximum piston speed of 1 m/s.

CAUTION
Risk of injury or damage!
A cylinder that is operated without speed control can reach high piston speeds, and may cause injury or machine breakdown.

• Make sure that the cylinder is always operated with speed control, e.g. byusing check-choke valves with exhaust air throttling.

The speed is normally controlled by throttling the exhaust air from the cylinder chambers with, for example, check-choke valves with exhaust air throttling.

NOTICE
Damage to the cylinder due to screwing in the check-choke valves too far!

1. Note the thread length of the check-choke valves if they are directly mounted in the cylinder covers.
2. Observe the wrench flats and wrench sizes.

When the speed is being set, the cylinder must be loaded as in normal service and the speed must be increased gradually to the desired operating speed.

• Do not set the operating speed higher than necessary. The speed must be adapted to the load of the cylinder in order to not exceed the maximum permitted cushioning energy. Use the calculation program in the online catalog.

Set the piston speed as follows:

1. Make sure that the pressure is zero and then increase the pressure slowly to the desired working pressure.
2. Slightly open the check-choke valves.
3. Increase the piston speed by opening the check-choke valves gradually to reach the desired operating speed.

Adjusting pneumatic cushioning

If you change the piston speed, the moving mass, or the working pressure, you have to adjust the pneumatic cushioning.

Fig. 4: Setting the cushioning

Depending on the configuration, your cylinder may be equipped with two pneumatic cushions. The cushioning is adjusted using throttle screws at both ends of the cylinder.

Basic setting

• Turn the two flow control screws clockwise up to the stop and then turn them back out a full rotation.
  This will prevent the piston from impacting without cushioning.

NOTICE
High mechanical cylinder load due to incorrect basic settings!
The cylinder may be damaged if the piston impacts without cushioning.

• Always perform basic setting adjustment.

Settings for both sides

Fig. 5: Adjusting pneumatic cushioning

Cushioning always has to be adjusted on both sides of the cylinder. The order does not matter.

• Retracting piston rod
• Extending piston rod

1. Repeatedly move the piston from end position to end position. Pay attention to the piston impact noise (hereinafter referred to as noise level) and the vibration behavior (hereinafter referred to as moving mass) of the overall system upon entering the cushioning phase.
   • The noise level is clearly audible.
   • The moving mass vibrates noticeably.
2. Slowly turn the throttle screws out. This lowers the cushioning.

Fig. 6: Unscrew flow control screws

3. Repeatedly move the piston from end position to end position. Pay attention to the noise level of the piston impact and the vibration behavior of the moving mass:

   • The noise level increases.
   • The mass vibrates less during piston impact.

4. Continue slowly turning the throttle screws out. This lowers the cushioning further. After every change to the throttle screws, move the piston from end position to end position.

   • The noise level initially continues to increase, but then decreases significantly.
   • The required number of turns for the two throttle screws can differ.

5. Repeat this process until you have achieved the ideal operating points for both cushions. How to recognize the ideal operating points for both cushions:

   • The piston impact is barely audible.

   • The vibration of the mass is minimal.
     If you now continue to turn out the throttle screws even further, you will abandon the ideal operating points:

   • The piston impact becomes louder.

   • The vibration of the mass increases.

• Turn the throttle screws in and return to the ideal operating points.

Care and Maintenance

DANGER
Danger of explosion through overheating caused by dust deposits!
The accumulation of dust can cause the product to overheat. The surface can no longer cool down and is heated at an uncontrollable rate. The resulting heat build-up presents an explosion hazard. Dust clouds can lead to explosions.

• Regularly remove dust deposits. Set binding cleaning intervals.

CAUTION
Danger of burns caused by hot surfaces!
Touching the surfaces of the product during operation could cause burns.

1. Let the product cool off before working on it.
2. Do not touch the product during operation.

CAUTION
Damage to the surface caused by solvents and aggressive detergents! The seals on the product may age faster under aggressive ambient conditions.

• Never use solvents or aggressive detergents.
