PREPARATION FOR DELIVERY5.1 Plated parts shall be handled and packaged in such a manner to ensure that the required physical characteristicsand properties of the plating are preserved.5.2 Packages of plated parts shall be prepared for shipment in accordance with commercial practice and in compliancewith applicable rules and regulations pertaining to the handling, packaging, and transportation of the parts to ensure carrier acceptance and safe delivery.6. ACKNOWLEDGMENTThe processor shall mention AMS 2401H in all quotations and when acknowledging purchase orders.7. REJECTIONSParts on which the plating does not conform to this specification, or to modifications authorized by the cognizant --``,,`,``,`,```,`,,`````,,`,`,,-`-`,,`,,`,`,,`---engineering organization, will be subject to rejection.8. NOTES8.1 A change bar (|) located in the left margin is for the convenience of the user in locating areas where technicalrevisions, not editorial changes, have been made to the previous issue of this specification. An (R) symbol to the left of the document title indicates a complete revision of the specification, including technical revisions. Change bars and (R) are not used in original publications, nor in specifications that contain editorial changes only.8.2 Current density of the plating solution will vary with the type of solution used and shall be adjusted to minimizeinfusion of hydrogen during processing.8.3 Part manufacturing operations, such as heat treatment, forming, joining and media finishing, can affect the conditionof the substrate for plating or, if performed after plating, could adversely affect the plate. The sequencing of these types of operations should be specified by the cognizant engineering organization and is not controlled by this specification.8.4 The parts manufacturer should ensure that surfaces of metal parts supplied to the processor are free fromblemishes, pits, tool marks, and other irregularities that will affect the quality of the finished parts. Defects and variations in appearance that arise from surface conditions of the substrate, such as porosity, scratches, or inclusions, that persist in the finished plate despite observance of industry accepted plating practices would not be considered as cause for rejection.8.5 An acid dip may be used for surface activation or neutralization of residual alkaline cleaner. However, the immersiontime should be minimized to preclude pitting.8.6 Following cleaning, parts should be immersed in an alkaline solution until transferred, after rinsing in clean water butwithout drying, to the plating solution. Abrasively cleaned parts should be agitated in the alkaline solution to remove residual abrasive. Parts should not be held in the solution for more than four hours before being transferred to the plating solution.8.7 ARP4992, Periodic Test Plan for Process Solutions, is recommended to satisfy the requirements for the control ofprocessing solutions.8.8 Terms used in AMS are clarified in ARP1917. ASTM B 374 “Terminology Relating to Electroplating” should beutilized as a reference and referee document when areas of design definition or technical interpretation arise.8.8.1 Plating is intended to be deposited in an uninterrupted process except as may be required by the operator formaking thickness measurements. After the plate has dried, resumption of plating can result in detectable visual discontinuities or weak interlaminar adhesion that may not be readily apparent. Such resumption of plating is known as ‘double plating’ and localized addition of plate is known as ‘spotting-in.’8.9 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions andproperties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.--``,,`,``,`,```,`,,`````,,`,`,,-`-`,,`,,`,`,,`---。

HN-2402马达保护器定值整定参考书
HN-2402马达保护器定值整定参考书装置为电机“起动”与“运行”两种运行状态均配置了多种保护功能，能自动检测电机起动事件，判断电机“起动”状态向“运行”状态的转化，并能自动切换保护定值。
若Ia Ib Ic的值全部小于Ie的20%则装置判定为当前无电流，当有一相或多相的值大于Ie的20%时装置判定电机发生了起动，并从该时刻开始计时，装置执行“起动”状态下的保护功能，经过Ts时间后装置认为电机转入“运行”状态，执行“运行”状态下的保护功能。
若在Ts时间内电流消失，则装置自动退出当前“起动/运行”状态的判断，并重新开始监视电机起动。
起动状态下的保护功1起动短路：若电流i（i为Ia Ib Ic三中的1相或多相）大于保护整定值I，状态持续时间大于动作时间T则保护动作，动作出口位置为起动B出口（端子14-15），同时保护跳闸信号开出。
以下除零序I段保护外，其他保护出口位置同此。
建议整定值I为8~10倍的额定电流Ie,出口时间T 为0~1S2、起动堵转：原理及判据同“起动短路”。
建议整定值I为8~10倍的额定电流Ie,出口时间T 为0~1S3、起动低电压：当Uab Ubc Uca3相线电压全小于保护整定值U，且Ia Ib Ic三相电流中的任何1相电流i>Ie/5，状态持续时间大于动作时间T则保护动作。
建议整定值U为0.45~0.95倍额定电压Ue,出口时间T 为0.1~25S，参考值为0.7Ue,5S.。
4起动超长：从装置判定电机发生起动开始，若持续时间到达动作时间T时3相电流依然全部大于保护整定值则保护动作。
运行状态下的保护功能1、短路保护：为电动机相间短路故障的保护, 若电流i（i为Ia Ib Ic三相中的1相或多相）大于保护整定值I，状态持续时间大于动作时间T则保护动作。
建议整定值I为6~10倍的额定电流Ie,出口时间T 为0~5S；参考值为9Ie,0s.2、堵转保护：电动机在起动过程中，由于负荷过大或自身机械原因，造成电动机轴被卡住，而未及时解除故障，将造成电机过热，绝缘降低而烧毁电机，堵转保护适用于电动机起动发生此类故障时进行保护，若电流i（i为Ia Ib Ic三相中的1相或多相）大于保护整定值I，状态持续时间大于动作时间T则保护动作，避免电机烧毁。
