22、TION This basic safety publication is intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and in ISO/IEC Guide 51. It should be noted that one of the responsibilities of a technical committee is, wherever possible, to
23、include or refer to the requirements of basic safety publications in standards for equipment within its scope. Consequently, the requirements of this basic safety publication apply only if they are included, or are referred to in those standards. Supervision and intervention are the principal tasks
24、of personnel engaged in the monitoring and control of equipment or processes. Indicator for the representation of conditions, and actuating devices to enable intervention under normal and fault conditions, are essential to this purpose. The information presented should meet the needs of the users fo
25、r the monitoring and control tasks which they are required to perform, for example, in extensive industrial processes. Safety and ergonomic aspects should also be taken into account. The use of only a single means of coding is often insufficient to ensure unambiguous representation of information. A
26、part from an unambiguous marking of the indicating and actuating devices, there is a requirement for a clear and consistent system of coding. The choice of a code will depend on the information which it is intended to impart. This may relate to the state of equipment (or part of it), to the conditio
27、n of a process, and/or to the effects which this condition has on persons, property and the environment. The user is required to decide on which of these criteria the coding for the relevant application is to be based. Page4 EN60073:200267003 EI2:C200 11 BASIC AND SAFETY PRINCIPLES FOR MAN-MACHINE I

29、ronment through the safe monitoring and control of the equipment or process; facilitate the proper monitoring, control and maintenance of the equipment or process; facilitate the rapid recognition of control conditions and actuator positions. This standard is for general application: from simple cas
