must also guarantee a safe operating condition for the whole system in the
event of a fault.
Although the handheld terminal is not, strictly speaking, a machine, it does,
however, perform important tasks to guarantee the safety functions of a ma-
chinery to which it is attached.
The handheld unit has, for example, the “Emergency Stop" safety function and
an enabling device for use in special operating modes. It is, as a result, a
“Safety Component" in the sense of the Machinery Directive.
Safety components, or parts whose failure or faulty operation put the safety of
people within the hazard area of the machine in danger, fall expressly within
the range of application of the Machinery Directive.
The fundamental requirements that the Machinery Directive places on the
manufacturer are as follows:
●
To carry out a hazard and risk analysis
●
To comply with the integration of safety principles
●
To compile and keep a technical construction file
●
To provide solutions in accordance with the latest state of the art
●
To recognise conformity by means of harmonised Standards
●
To apply CE marking
The same basic requirements apply to safety components. In their particular
case, it must be proven that failure or malfunction are not possible, or that
malfunction does not lead to a hazardous situation.
14.2.1 "Hazard and Risk Analysis"
The manufacturer of a machine is required to analyse its machine throughout
its operating life and in all modes of operation, and to document all hazards
that may possibly arise. This has to be done without taking into account pos-
sible protection devices.
The next step is to formulate a goal for protection against each identified hazard
and subsequently to define one or more protective measures to achieve the
protection goal.
Further details about the procedure for carrying out the hazard and risk anal-
ysis and lists of commonly occurring hazards can be found in the following
Standards:
●
EN 12100-1 and EN 12100-2 "Safety for machinery - Basic concepts, gen-
eral principles for design"
●
EN 14121-1 "Safety of machinery - Risk assessment"
14.2.2 "Principles for the Integration of Safety"
In Appendix I, Chapter 1.1.2 of the Machinery Directive 2006/42/EC there is a
clear procedure and sequence for the selection of protective measures:
