This part of IEC 60947 series provides additional requirements to those given in IEC 60947-5-2. It addresses the fault performance aspects of proximity devices with a defined behaviour under fault conditions (PDDB). It does not address any other characteristics that can be required for specific applications. This standard does not cover proximity devices with analogue output. This Standard does not deal with any specific requirements on acoustic noise as the noise emission of control circuit devices and switching elements is not considered to be a relevant hazard. For a PDDB used in applications where additional characteristics, dealt with in other standards, are required, the requirements of all relevant standards apply. The use of this standard alone does not demonstrate suitability for the implementation of any specific safety related functionality. In particular, this standard does not provide requirements for the actuation characteristics of a PDDB, or for means to reduce the effects of mutual interference between devices, e.g. coded targets. Therefore these and any other application-specific requirements will need to be considered in addition to the requirements of this standard. NOTE 1 Due to their behaviour under fault conditions, PDDBs can, for example, be used as interlocking devices (see ISO 14119). NOTE 2 The requirements for electro-sensitive protective equipment for the detection of persons are given in the IEC 61496 series.

由此可见,合理选泵对节约能源同样具有重要意义。 所谓合理选泵,就是要综合考虑水泵机组和泵站的投资和运行费用等综合性的技术经济指标,使之符合经济、安全、适用的原则。具体来说,有以下几个方面: 必须满足使用流量和扬程的要求,即要求泵的运行工次点(装置特性曲线 与水泵的性能曲线的交点)经常保持在高效区间运行,这样既省动力又不易损坏机件。...
