Reliable and efficient protection of safeguards includes not only the safety locking device but also an additional control unit and suitable wiring and control technology. Pilz safety sensors can be connected in series and are compatible with other products and interfaces. They perfectly fit into their plant environment and also enable Pilz components to be retrofitted to your plant. http://www.pilz.com

The safety gate cannot be opened until all hazardous machine movements are stopped. A restart is not possible until the safety gate is closed and locked. It must not be possible to either defeat or manipulate the safeguards. Movable guards such as swing gates and sliding gates, flaps or covers, can be found in almost every application. If there are dangerous overrun movements, a safety locking device with appropriate manipulation protection in accordance with EN ISO 14119 is required. 

The question regarding the type of guard locking depends on the stopping time. If the time to reach the danger zone is longer than the stopping time, process guarding is sufficient. If the intervention time is shorter than the stopping time, however, safe guard locking (personnel protection) is required. The level of protection is defined in accordance with EN ISO 13849-1 or EN 62061. The key factors for this calculation, for example, are the severity of the potential injuries, frequency of exposure to the risk and ability to avoid the risks.
