EN and prEN contain details of safety requirements and orientation aids for the design, construction, programming, operation, maintenance and repair of safetyrelated parts of control systems for machinery. They also apply to all machinery applications for professional and non-professional use.
Where appropriate, they can also apply to the safety-related parts of control systems used in other technical applications with similar hazards. The categories used in the standards are designed to allow for component faults and to accept fault exclusion. Fault exclusion means that a fault can be excluded if the chances of it arising or occurring are improbable.
In order to have objective and verifiable criteria, EN publishes lists of potential component faults which need to be taken into account when evaluating safetyrelated parts of control systems.
These lists of faults do not claim to be exhaustive and, if necessary, additional faults should also be considered. The graphic below may be helpful. The categories are not intended to be used in any given order or in any given hierarchy in respect of safety requirements. The risk assessment will indicate whether the total or partial loss of the safety function s arising from faults is acceptable.
It is clear, therefore, that discussions over whether product XY should be category 2, 3 or 4 goes against the intentions of the standards committee and is not in the spirit of the standard.
Most machines have a front and a back. The dangerous side is the front, because it is generally from there that the machine is assembled and operated. The back of the machine is less dangerous because it can usually be encased by metal plates and guard rails.

Appropriate measures should be used to reduce the anticipated risk to the level of safety required for the application. The occurrence of a fault can lead to the loss of the safety function 1 Requirements of B shall apply.
Use of well-tried components and well-tried safety principles. As for category B, but with greater safetyrelated reliability of the safety functions. Safety function shall be checked at suitable intervals by the machine control system.
The occurrence of a fault can lead to the loss of the safety function between the checks. The loss of the safety function is detected by the check. Safety-related parts shall be designed so that: — a single fault in any of these parts does not lead to a loss of the safety function; and — whenever reasonably practicable, the single fault is detected. When the single fault occurs, the safety function is always performed. Some but not all faults will be detected.
Accumulation of undetected faults can lead to the loss of the safety function. Safety-related parts shall be designed so that: — a single fault in the control system does not lead to a loss of the safety function; and — the single fault is detected at or before the next demand upon the safety function. If this is not possible, then an accumulation of faults shall not lead to a loss of the safety function.
When the faults occur the safety function is always performed. The faults will be detected in time to prevent the loss of the safety function.
Principles to achieve safety 1 Mainly characterised by selection of components. Mainly characterised by structure. This is followed by descriptions of the specific units and application examples. The appendix contains a table showing the chemical resistance of the safety switches. This technical catalogue is divided into the following chapters: 1 Introduction The introduction is designed to familiarise you with the contents, structure and specific order of this technical catalogue.
This warning must be heeded! It warns of a hazardous situation that poses an immediate threat of serious injury and death and indicates preventive measures that can be taken.
It warns of a hazardous situation that could lead to serious injury and death and indicates preventive measures that can be taken. This refers to a hazard that can lead to a less serious or minor injury plus material damage, and also provides information on preventive measures that can be taken.
NOTICE This describes a situation in which the unit s could be damaged and also provides information on preventive measures that can be taken. The PSEN product range consists of noncontact, magnetic safety switches, which monitor the position of movable protection devices in conjunction with an actuator and an evaluation device.
For safety-related applications, the safety switches must only be used in conjunction with approved evaluation devices. Approved, complete solutions are available for evaluating the position of rotatable, removable and displaceable safety devices in accordance with EN The safety system guarantees functional safety, but not the safety of the entire application.
You should therefore define the safety requirements for the plant as a whole, and also define how these will be implemented from a technical and organisational standpoint. You must observe the warning notes given in other parts of this technical catalogue.
These are highlighted visually through the use of symbols. Each safety switch has an approved actuator. Together with an authorised evaluation device they form an approved, complete solution. If the actuator is within the response range, the magnets switch the reed contacts on the safety switch. If the actuator is outside the response range safety gate open , the reed contacts on the safety switch will switch. On some safety switches this is signalled by a red LED.
Switching distance: Safety switches with different switching distances are available for different applications, e. A high lateral and vertical offset can be achieved with long switching distances. This will provide greater tolerances for installation and even less sensitivy towards spring-back or swinging from safety gates.
The safety switches therefore have a hysteresis. If the actuator is within sao, vibrations up to sar will not cause the safety switch to de-energise. Sensing face PSEN product range 2. Switching distances may deviate if other arrangements are used. With a round or square design, the safety switches can easily be adapted to suit installation requirements.
Evaluation devices: Each safety switch has an approved evaluation device and possibly also an interface.
Vertical offset sar Connecting safety switches in series: Several safety switches are connected to an input on an evaluation device via an interface. This means, for example, that several safety gates on a plant can be monitored using a single evaluation device. Movements in which the actuator is tilted in relation to the safety switch are not permitted Fig.
This must be defined so that the evaluation device can detect the status of the safety switch. This value is device-specific. The interface type and the number of safety switches that can be connected will depend on the selected evaluation device.
The interface connects the safety switches in series to the evaluation device.

The switch status of the individual safety switches safety gate open or closed is displayed through LEDs and can be evaluated via auxiliary outputs, e. Cable with connector: The cables for the safety sensors have a plug-in connection. This enables the cable and switches to be installed separately. The plug connectors are 4-pin male M8 screw connectors with lock.
They are available straight or angled. If an interface e.
This means the safety switches can be used for applications up to category 3 in accordance with EN However, the sensing faces of the safety switch and actuator should be positioned opposite each other in parallel.
