标准范围

本文件规定了双手控制装置（THCD）的安全要求以及手动驱动控制驱动装置的输出信号的相关性。本文件描述了THCD实现安全性的主要特征，并列出了三种类型的功能特征组合。它不适用于拟用作启用设备、保持运行设备或特殊控制设备的设备。本文件未规定THCD应与哪些机器一起使用。它也没有具体说明哪两种类型-手动控制装置应用于特定应用。此外，虽然给出了指南，但并未规定THCD和危险区之间所需的距离（见8.8）。本文件提供了THCD选择（基于风险评估）的设计要求和指导，包括防止失败、避免故障和验证合规性。注1:THCD仅为使用者提供保护。注2:对于特定机器，双手控制装置作为适当保护装置的适用性可在类型中定义-C标准。如果此类标准不存在或不适用，则风险评估和适当保护措施的确定由机器制造商负责。本文件适用于所有THCD，与所用能量无关，包括:-为安装而完全组装的THCD；-由机器制造商或集成商组装的THCD。本文件不适用于出版日期之前制造的THCD。

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.
