本欧洲标准规定了双手控制装置的安全要求和输入信号的输出信号的依赖性，并描述了双手控制装置的主要特性，以实现安全性，并为三个控制装置的功能特性组合类型。它不适用于旨在用作启用设备的设备，作为保持运行设备或特殊控制设备。本欧洲标准提供了双手控制装置的设计和选择（基于风险评估）的要求和指导，包括评估，防止失败和避免故障。它还提供了包含可编程电子系统的双手控制装置的要求和指导。它适用于所有双手控制装置，与所使用的能量无关，包括双手控制装置，它们是或不是机器的组成部分，以及由一个或多个单独元件组成的双手控制装置

This document specifies the safety requirements of a two-hand control device (THCD) and the dependency of the output signal from the actuation by hand of the control actuating devices. This document describes the main characteristics of THCDs for the achievement of safety and sets out combinations of functional characteristics for three types. It does not apply to devices intended to be used as enabling devices, as hold-to-run devices or as special control devices. This document does not specify with which machines THCDs shall be used. It also does not specify which types of two-hand-control device shall be used for a specific application. Moreover, while guidance is given, it does not specify the required distance between the THCD and the danger zone (see 8.8). This document provides requirements for design and guidance on the selection (based on a risk assessment) of THCDs including the prevention of defeat, the avoidance of faults and verification of compliance. NOTE 1 A THCD only offers protection for the person using it. NOTE 2 For specific machines, the suitability of a two-hand control as a suitable protective device can be defined in a type-C standard. If such a standard does not exist or is not appropriate, the risk assessment and determination of suitable protective measures is the responsibility of the manufacturer of the machine. This document applies to all THCDs, independent of the energy used, including: — THCDs which are fully assembled for installation; — THCDs which are assembled by the machine manufacturer or integrator. This document is not applicable to THCDs manufactured before the date of its publication.
