1 Scope
This National Standard specifies the safety requirements for automated function controls and control systems for the following automated functions of industrial trucks (hereinafter referred to as "truck"):
-Steering (excluding direct mechanical guidance);
-Travel;
-Lifting and lowering operations;
-Load manipulations, e.g. rotation, reach, slewing, tilting, clamping;
-Combination and/or sequence of the above movements
Note: The control system is generally part of the truck but can include components external to the truck, e.g. the means of guidance for automated steering.
This National Standard is intended for use in conjunction with one or more of the applicable parts of ISO 3691.
Limitations in the scopes of the applicable parts of ISO 3691 also apply to this National Standard.
This National Standard is not applicable to, and does not include, requirements for the following:
-Safety equipment (e.g. devices for height limitation, speed limitation) used to override operator control;
-Operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields);
-Operation in environments subject to special rules (e.g. potentially explosive atmospheres);
-Electromagnetic compatibility;
-Transportation of passengers;
-Handling of loads, the nature of which could lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials).

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1 Automated function
Movement for transport or positioning of the truck and/or load initiated by the operator but not requiring continued action by the operator.
3.2 Automated lifting and lowering
Automated function that controls intended vertical movements and/or positioning of the load-carrying device to a preselected height.
3.3 Automated load manipulation
Automated function that controls load movements (e.g. rotation, reach, slewing, tilting, telescoping, clamping).
3.4 Automated steering
Automated function that takes control of the steering and keeps the truck on a predetermined path.
Note: Automated steering excludes any direct mechanical guidance (e.g. by means of a rail) and manually controlled steering systems equipped with feedback signal(s) for regulating the steering system.
3.5 Automated steering acquisition
System condition when automated steering has been selected but the operator is still positioning the truck to acquire the guidance means, i.e. the operator still has control of the manual truck steering system.
3.6 Automated travel
Automated function that takes control of the speed and direction of travel and/or positioning of the truck.
3.7 Sequenced automated functions
Succession of automated functions in which each movement can commence only after the completion of the previous movement.
3.8 Combined automated control
Automated system that takes control of two or more automated functions simultaneously.
3.9 Responsible person
Designated person suitably trained and qualified by knowledge and practical experience and in possession of the necessary instructions to enable the assigned task to be carried out.
