Pneumatics rank among the drive technologies in engineering, alongside electrics and hydraulics.
Safe pneumatic equipment of machinery
Safe pneumatics can be divided into two areas:
- Basic principles in accordance with EN ISO 13849-2 in Annex B. For example: compressed air preparation or pressure limitation.
- Appropriate protective measures for pneumatic drives (control technology solutions that move a cylinder in accordance with a desired behaviour).
Protective measures for safety-related pneumatics describe circuit-based solutions. These include:
- Protection against unexpected start-up
- Ventilation and venting
- Braking the movement
- Blocking the movement
- Reversing the movement
- Free movement option
- Balancing forces on the drive
