Both the Electromagnetic Compatibility Directive (EMC 89/336/EC) and the
Machinery Directive (MD 98/37/EC) are applicable to the handheld termi-
nals.
14.2 Machinery Safety
Additional measures must be taken wherever faults arising in the machin-
ery may cause personal injury or significant material damage. These
measures 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
machinery 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:
z
To carry out a hazard and risk analysis
z
To comply with the integration of safety principles
z
To compile and keep a technical construction file
z
To provide solutions in accordance with the latest state of the art
z
To recognise conformity by means of harmonised Standards
z
To apply CE marking
The same basic requirements apply to safety components. In their particu-
lar 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 through-
out its operating life and in all modes of operation, and to document all
hazards that may possibly arise.
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.
