Clamping of the sensors separately. The maximum possible end position adjustment is specified in the catalog. In order to adapt the shock absorber s characteristic curve to the occurring kinetic energy, the stroke of the shock absorber and thus also the characteristic can be adapted. Adjustment of shock absorber Loosen the securing of the adjusting screw. 2 Set the adjusting screw of the damping adjustment to the desired amount.! Note the adjustment range! 3 Tighten the adjustment screw again. The adjusting screw for the shock absorber LMD (2) can be used to adjust the stroke of the shock absorber to adapt the shock absorber characteristic to the occurring kinetic energy. To do so, loosen the lock nut and turn the adjusting screw (2) to achieve the proper adjustment. The minimum and maximum adjustment values for the end position adjustment are specified in the catalog. 3.3 LM 25-3 en 7

Mounting and commissioning 7.4 Adjustment of the shock absorber strocke The shock absorber stroke is too long and the end position is reached too slowly. The shock absorber stroke is too short and the unit arrives in the end position too abruptly. Optimal shock absorber stroke. 8 3.3 LM 25-3 en

Mounting and commissioning 7.5 Setting the speed NOTICE Damage to the product is possible! The product can be damaged if it arrives too abruptly in the end position. The exhaust flow control valves and the shock absorbers must be adjusted so that the rotation gradually and smoothly decelerates. Completely close the exhaust flow control valves. 2 Slowly and gradually open the exhaust flow control valves and rotate the load. 3 Further open the exhaust flow control valves until the rotation gradually and smoothly decelerates. If the speed is too low the swivel unit brakes too soon and the end position is reached to slowly. If the speed is too high the swivel unit impacts in the end position and the shock absorber will be overloaded. NOTE NOTE In most cases the rotation will still be too slow. Further adjustment and optimization of the swivel time is achieved via adjusting the shock absorber stroke, ( 7.5, Page 8). 3.3 LM 25-3 en 9

Commissioning 8 Commissioning NOTICE Before commissioning! Please read these instructions carefully. Only with the knowledge of this manual errors can be prevented, and trouble-free operation is ensured. Check technical specifications ( 6, Page 3). Do not use the linear module until you have determined that it is in perfect operating condition, after having checked for compliance with all permissible operating parameters. When mounting loads, take measures to prevent impermissible forces and torques. Do not subject the linear module to loads outside of the operating range. Excessive loads can result in damage or inaccuracy of the guide unit. The maximum permissible loads are specified in our standard catalog. Regulate the operating speed of the cylinder with regulator valves ( 7.2, Page 5). Starting slow, increase the speed until the desired operating speed is reached. NOTICE Risk of mechanical damage of the module! The module must always be adjusted so that no mechanical impacts are produced when reaching the end position. 2 3.3 LM 25-3 en
