26、TA regulations. This document is a type B standard as stated in EN ISO 12100. The provisions of this document can be supplemented or modified by a type C standard. NOTE For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions

27、 of that standard, the provisions of that type C standard take precedence over the provisions of this type B standard. DIN EN 894-4:2010-11 EN 894-4:2010 (E) 5 1 Scope This European Standard contains ergonomic requirements for the location and arrangement of displays and control actuators in order t

28、o avoid hazards associated with their use. This European Standard applies to displays and control actuators for machinery and other interactive equipment (e.g. devices and installations, instrument panels, control and monitoring consoles). This European Standard is not applicable to the location and

29、 arrangement of displays and control actuators which are manufactured before the date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated referenc

34、splay ratio C/D ratio ratio of the movement of a control actuator to that of an associated element, display or controlled object 3.2 elements generic term for displays and control actuators on consoles and panels 3.3 primary element element frequently used for direct operation and monitoring of the

35、system which includes safety and emergency related elements DIN EN 894-4:2010-11 EN 894-4:2010 (E) 6 3.4 secondary element element not frequently used for the direct operation of a system EXAMPLE The time and duration of use can be freely selected. 3.5 grouping arrangement of several elements of a s

36、ystem in such a way that they appear to be associated functionally 3.6 coding procedure within the design process by which categories of information (e.g. form, colour, etc.) are allocated to elements for the purpose of reliable identification 3.7 arrangement way of combining or separating displays

37、and control actuators relative to their function, task and/or location 3.8 surface surface on which elements are positioned and arranged, considering task priorities, information flows, and space constraints 4 Principles for location and arrangement of displays and control actuators The location and

38、 arrangement of displays and control actuators are intended to ensure the general reliability, safety and efficiency of the human-machine system. The most important tasks of the operator are to monitor, control and ensure continuous availability of the technical system and the interaction of its ele

39、ments. This shall place the operator in a position to fulfil the following functions correctly and on time without becoming overtaxed: to perceive the current tasks; to control the operation; to select and/or develop suitable action strategies. Basic principles for human machine interaction are give

40、n in EN 894-1. The following describes a design procedure that will assist designers and manufacturers in complying with the requirements in this standard. It consists of six main phases, each of which contains several more detailed steps. These steps should be carried out iteratively until the requ

41、irements are met. The procedure is illustrated in Figure 1. In Phase 0 the initial information about the overall purpose, design goals and roles of the operators (see EN 894-1) is assembled.

42、rangement NOTE For details of each step see Clause 5 (e.g. step 1.1 is in 5.1.1; step 3.1 in 5.3.1). DIN EN 894-4:2010-11 EN 894-4:2010 (E) 8 5 Phases and steps for location and arrangement of displays and control actuators 5.1 Phase 1 Evaluation of task/activities and information collection 5.1.1 S

43、tep 1.1 Define tasks and functions Typical operator tasks are e.g. monitoring, error detection, diagnosis of faults and performing control actions; the following operating situations should be considered: start up, normal operation, troubleshooting, shutdown, emergency stop, etc., see EN 894-1, -2 a

44、nd -3. Task sequence and relevant information flows shall be recorded for each relevant operating situation. If two or more operators may work at the same workplace the interactions between their tasks, control actions and information flows shall be specified to help avoid possible conflicts and imp

45、rove overall safety. 5.1.2 Step 1.2 Determine the operators relevant physical and cognitive characteristics The general principle as defined in EN 614-1, e.g. strength, body size, visual acuity, skills, experience and disabilities, shall be considered. Specific information on relevant physical chara

46、cteristics for displays and control actuators is given in EN 894-2 and -3. 5.2 Phase 2 Evaluation of task requirements and constraints 5.2.1 Step 2.1 List of displays and control actuators Types of displays and control actuators which comply with the relevant requirements of EN 894-2 and EN 894-3 sh

47、ould be compiled in a list. Technological features and/or constraints such as for multifunctional elements, e.g. touch screens, scroll balls, remote or handheld controllers need to be assessed. 5.2.2 Step 2.2 Determine general priorities The task requirements for each operational situation shall be

48、specified and prioritized taking into account safety, performance and usability goals. Task requirements include accuracy, speed, force, frequency, importance, duration of use, sensitivity to error and sequence of use, etc. Tasks should be assigned a level of priority, i.e. primary or secondary elem

49、ents as defined in 3.3 and 3.4. These priorities are used in Phase 3 to help locate displays and control actuators, and to exclude unnecessary elements. The activities that make up the tasks should be identified, this helps to choose the most appropriate physical arrangements, e.g. which parts of the task can be done seated, which parts of the task require
