Georg Schlegel: Fully Automatic Test System
The active illuminated emergency-stop QRBDUV with diagnostic unit and anti-lock collar enhances safety at work in producing enterprises.
According to the previous valid standard DIN EN ISO 13850 an inactive fix mounted emergency-stop had to be covered in order to prevent any possibility of confusion in case of emergency. In practice however, this was not always easily feasible so that inactive and not covered emergency-stops possibly could cause accidents. This standard has been extended and allows the use of active illuminated emergency-stops as alternative. In case the modular plant part is connected to the overall system, the active status of the emergency-stop is signaled by illumination. If there is no connection the actuator is not illuminated, thus transparent and so it informs on the inactivity of the actuator.
