German PILZ relay mechanical protection choice
PILZ safety relay, PILZ China office, PILZ switch, Pilz safety relay
Mechanical protection design, as part of the reduction in machine risk, is an important safety feature designed to protect personnel from mechanical damage by physical isolation. In the European standard EN 953 "Mechanical safety - mechanical protection - general requirements for the design and implementation of fixed and mobile guards", the types of mechanical protection, the choice of methods, the requirements of mechanical protective materials and the safety requirements for mechanical protection are defined. Content. Many sources of danger in the production process use mechanical protection, but does the mechanical protection in your factory meet the requirements of the standard?
According to EN 953, when choosing mechanical protection, we refer to the following important aspects:
● Existing risks in the machine, such as noise, radiation, explosion and other risks. For example, a drill press, considering the danger of iron filings, the wire mesh protection is not suitable.
● There is no secondary risk. The mechanical protection needs to take into account the convenience of operation. At the same time, it is necessary to provide sufficient visual field to ensure that the personnel are not in the danger zone when the machine starts.
● Reasons and frequencies for entering mechanical protection, such as areas that need to be accessed during machine maintenance. We recommend fixed protection. If the area needs to be entered during production, movable protection with interlocking is a good choice.
