Safety of machinery - Ergonomics requirements for the design of displays and control actuators - Part 1: General principles for human interactions with displays and control actuators

This European Standard applies to the design of displays and control actuators on machinery. It specifies general principles for human interaction with displays and control actuators, to minimise operator errors and to ensure an efficient interaction between the operator and the equipment. It is particularly important to observe these principles when an operator error may lead to injury or damage to health.

La présente norme européenne s'applique à la conception des dispositifs de signalisation et des organes de service
des machines. Elle spécifie les principes généraux des interactions entre l'homme et ces dispositifs pour réduire au
minimum les risques d'erreur humaine et assurer une interaction efficace entre l'opérateur et l'équipement. Le respect
de ces principes est particulièrement important lorsqu'une erreur de l'opérateur peut induire des risques en matière
de santé ou de sécurité.

general principles for human interaction with displays and control actuators, to minimise operator errors and to
ensure an efficient interaction between the operator and the equipment. It is particularly important to observe
these principles when an operator error may lead to injury or damage to health.

3 Definitions
For the purposes of this European Standard, the following definitions apply:
3.1
control actuator
the part of the control actuating system that is directly actuated by the operator, e.g. by applying pressure
3.2
display
device for presenting information that can change with the aim of making things visible, audible or
discriminable by touch (tactile)
3.3
operator
the person or persons given the task of installing, operating, adjusting, maintaining, cleaning, repairing or
transporting machinery [EN 292-1].
4 Design principles for operator-task relationships
Human-machine systems are considered here as closed loops: the machine displays information to the
operator who uses control actuators to affect the machine, which in turn provides feedback to the operator,
etc.
Human-machine systems can comprise any number of man-machine units or subsystems, in which a single
operator interacts with a machine or process. Several subsystems may act independently or interact with each
other. When considering the requirements for a particular human-machine subsystem it is important to assess
how it interacts with the system as a whole.
Moreover, human-machine systems are part of more complex systems. For example, the physical
environment (noise, lighting, etc.) as well as the social and organisational environment can affect the efficient
operation of human-machine systems.
Knowledge of ergonomics principles is the basis for a successful implementation of a human-machine system.
In particular, it is important to ensure that systems are designed as an iterative process between the designer
and the users. EN 614-1 provides a framework for incorporating ergonomics principles in the design process
that shall be taken into account when designing machines. This framework can help designers to take account
of the principles in this standard.
An important factor to consider is the degree to which the human operator is needed in the system in order to
accomplish the given task. The informative annex A summarizes information on the capabilities of humans
when interacting with machines. The designer shall consider if the planned allocation of a particular function in
a man-machine system is in accordance with human capabilities. If this is not the case, the designer shall
redesign the system. A result of the redesign may be a (sub) system without the involvement of an operator.
The overall principle which concerns human-machine systems is that the machine and its associated
elements (displays, controls, instructions, etc) shall be suitable for the operator and the given task. In order to
realise this general principle, the machine system shall be so designed that human characteristics with
respect to physical, psychological and social aspects are considered. The following clauses present
ergonomics principles that shall be considered when designing a human-machine syst
