適用范圍：This standard specifies the safety requirements of a two-hand control device and its logic unit as defined in3.1.This standard describes the main characteristics of two-hand control devices for the achievement of safetyand sets out combinations of functional characteristics for three types. This standard does not apply todevices intended to be used as enabling devices, hold to run devices and as special control devices.This standard does not specify with which machines two-hand control devices shall be used. It also does notspecify which types of two-hand-control device shall be used. Moreover it does not specify the distancebetween the two-hand control device and the danger zone (see 9.8).The standard provides requirements and guidance on the design and selection (based on a risk assessment)of two-hand control devices including their assessment, the prevention of defeat and the avoidance of faults.The standard also provides requirements and guidance for two-hand control devices containing aprogrammable electronic system (see 7).This standard applies to all two-hand control devices, independent of the energy used, including:? Two-hand control devices which are or are not integral parts of a machine;? Two-hand control devices which consist of one or more than one separate elements.
