Questions and answers on the standard EN ISO 14119:2013 Safety of machinery. Interlocking devices associated with guards. Principles for design and selection These guidelines provide an aid to the application of EN ISO 14119 in the form of a procedure for the selection of a suitable interlocking or guard locking device. However, the guidelines are no substitute for reading the standard, as the entire contents cannot be given. devices in a reasonably foreseeable manner” may be the same as in EN 1088, however the procedure is described in significantly more detail and more straightforwardly....

Which conditions must a guard locking device meet for process protection according to EN ISO 14119? In the “locked” position a prevention of inadvertent locking position ensures that the safety door is in the “closed” position. In relation to the guard locking device and the control of the guard locking, it must be ensured that the interlocking function (the monitoring of the position of the safety door) is not degraded. In addition all requirements on the interlock must be met. ► The first safety function of an interlock, whether with or without process protection guard locking, is the...

Escape release Emergency release The emergency release, also not a safety function, is used to make it possible to reach the danger area in a machine quickly in an emergency. An example here is the outbreak of a fire in the system that must be extinguished quickly. In this case access without tools is possible. To reset the emergency release a tool or similar must be used. The closed-circuit current principle for guard locking solenoids can be used in almost all cases with an emergency release if rapid access to the machine from the exterior must be ensured. The usage of a release feature...

Selection of supplementary Selection of an interlocking device with or without guard locking (3) releases EN ISO 14119 Selection of type of interlocking device EN ISO 14119 Selection of level of coding EN ISO 14119 Selection of safety switch EN ISO 14119 26 What is the purpose of division into types? The division is used in the standard to formulate different requirements on the various possible interlocking devices. The standard differentiates between four types: T ype 1 Uncoded mechanically actuated position switch Type 2 Coded mechanically actuated position switch Type 3 Uncoded...

Which levels of coding are there and for what are they required? There are three levels of coding for actuators: L ow Up to 9 different actuators are available edium M 10 to 1000 different actuators are available igh H More than 1000 different actuators are available In the standard this information refers to the number of different actuators. Mechanical safety switches with separate actuator correspond to the low level of coding. Transponder-coded safety switches from EUCHNER are available with low and high coding. Multicode devices have low coding, conversely all unicode devices have high...
