comply with general requirements for EMC.
For electrical devices which are parts of drive systems, the requirements of those sections of EN 13223 listed in its
scope as relating to drive systems should be observed.
This standard contains requirements for prevention of accidents and protection of workers.
This standard does not apply to cableways for transportation of goods or to inclined lifts.

EN 13243:2004 (E) 7 3 Terms and definitions For the purposes of this document, the terms and definitions given in prEN 1907:2004 and the following apply. 3.1 Basic principles, general 3.1.1 safety function all the procedures that recognize the occurrence of certain conditions or operations that together make up a hazardous situation These procedures initiate processes that reduce the risks involved particularly by stopping the installation. A safety function starts with an assessment of the conditions and physical parameters in the cableway and ends with initiation of the process or completion of the procedure initiated 3.1.2 electrical safety device all the components used to implement all the operations of a safety function. Electrical safety devices may be of Type A or Type B (see 4.2.2.1) 3.1.3 remote monitoring installation, signalling installation installation used to transmit commands and information between the cableway stations or between stations and carriers 3.1.4 suspension of safety functions process whereby safety functions are put out of operation by deliberate switching 3.1.5 fault exclusion exclusion of a theoretically possible fault as a result of special measures 3.1.6 fault tolerance time time period during which a process can be impaired by erroneous control signals without a dangerous state occurring 3.2 Electrical circuits 3.2.1 break circuit circuit that normally carries current continuously. The desired function is initiated by interrupting the current flow 3.2.2 make circuit circuit in which no current normally flows. The desired function is initiated by generating current flow 3.2.3 safety circuits electrical circuits on which safety functions and emergency stopping devices act directly, or which monitor and compare physical parameters relevant to safety (e.g. set point value/actual value monitoring, deceleration monitoring). They bring the cableway to a stop or prevent unwanted start-up 3.2.4 line safety circuits safety circuits operated directly by the safety functions and emergency stopping devices on the line. They are also used for monitoring various ropes and cables for failure, contact with each other and earthing

From it, the cableway can be controlled and brought to rest and all the modes of control can be monitored 3.4.5 ready for operation an installation is ready for operation when no safety function or emergency stopping device is blocking start-up 3.4.6 ready signal control signal from the control points to the control console indicating readiness for the cableway to start up

EN 12927-8, EN 12929-1, EN 12929-2, EN 12930, EN 12397, EN 12408, EN 13223, EN 13107, prEN 13796-1, prEN 13796-2, prEN 13796-3. 4.1.2 EN 60204-1 applies where this document does not contain different requirements, except for the sections on control functions, safety interlocks, control functions in the case of faults, electronic components and technical documentation. 4.2 Safety principles 4.2.1 Hazard scenarios The safety principles set out in EN 12929-1 apply. In addition, the following hazard scenarios and safety measures apply within the scope of this document. 4.2.1.1 The following events many lead to hazardous situations which may be avoided or limited by the requirements of this document: a) accidental contact of a person with a live metallic component; b) failure of an electrical safety function; c) voltage drop or total loss of voltage; d) occurrence of a short-circuit, earth fault or open circuit; e) failure of electrical or electronic components; f) foreseeable external influences, in particular, environmental conditions and electromagnetic fields. 4.2.1.2 For each individual safety function, the hazard to persons is to be defined by means of a risk analysis (see also Annex A). A distinction is made between the following 3 hazard categories: a) Hazard category 1: failure of an electrical device that cannot lead to an accident (no personal hazard);
EN 13243:2004 (E) 10 b) Hazard category 2: failure of an electrical device that could lead to a slight accident (reversible injuries to persons); c) Hazard category 3: failure of an electrical device that could lead to a serious accident (irreversible injuries, death of persons). 4.2.1.3 The safety functions are allocated to 4 graded requirement classes (see 4.2.2.4) taking into account the respective hazard category and the probability of occurrence of the hazardous situation. The requirement class of a safety function is determined as shown in the diagram in Annex A. Examples of this allocation are given in informative Annex C. NOTE Additions may be made to these examples of allocation in informative Annex C during the next few years. 4.2.2 Safety measures The safety measures to be taken to eliminate the hazard scenarios listed under 4.2.1 are the following: 4.2.2.1 Division of the components used 4.2.2.1.1 An electrical safety device is of type A if: a) the failure behaviour of all components is well defined; and if b) the behaviour of the assembly under fault conditions can be completely determined; and if c) reliable failure rate data from actual experience exist for components or the assembly. 4.2.2.1.2 An electrical safety device is of type B if it cannot be classified as being of type A. 4.2.2.2 It shall be ensured that, in the event of a danger to persons, the cableway is automatically put into a safe state according to the hazardous situation. 4.2.2.3 Measures to be taken concerning software or hardware to try to prevent accidental or systematic faults from occurring shall be executed corresponding to the applicable requirement classes. In principle, it may be assumed that maintenance will be carried out in accordance with the specifications 4.2.2.4 Type A safety devices shall meet the following requirements, depending on the applicable requirement class: a) requirement class 1: electrical devices shall be designed, selected, assembled and installed in accordance with the state of the art so that they can at least adequately withstand the expected operating stresses and external influences; b) requirement class 2: the requirements of requirement class 1 shall be met and well-tried components and well-tried safety principles shall be used. The safety functions of the electrical safety devices of requirement class 2 shall be tested at suitable intervals (automatic or manual tests). The occurrence of a fault may lead to the loss of the safety function between the test intervals; c) requirement class 3: the requirements of requirement class 2 shall be met. Electrical safety devices of requirement class 3 shall be designed so that a single fault in one of these devices does not lead to the loss of the safety functions. The occurrence of a second fault may lead to the loss of the safety functions between the test intervals (automatic or manual tests); d) requirement class 4: the requirements of requirement class 3 shall be met. Electrical safety devices of requirements class 4 shall be designed so that a single fault in one of these devices does not lead to the loss of the safety functions and: 1) the single fault, while always possible, is identified at or before the next call for the safety function or else results in putting the cableway into a safe state; or
EN 13243:2004 (E) 11 2) if this is not possible, then a second fault does not lead to the loss of the safety function and results in putting the cableway into a safe state. If automatic or manual tests at periodic intervals in accordance with 4.2.2.10 c) run with a high degree of fault discovery, so that the first fault is recognized before another fault occurs, a second fault need not be considered. NOTE A high degree of fault detection may mean that 99 % of all faults to be considered are to be detected. 4.2.2.5 Type B safety devices, in addition to meeting the requirements for type A, shall also meet the following requirements: a)
1) the structure of the safety device, the interaction of components and the way in which the components are connected shall clearly and comprehensibly m
