Risk minimization through Safety Integrated
Safety Integrated can be used to minimize the level of risk associated with machines and
plants.
Machines and plants can only be operated safely in conjunction with Safety Integrated
when the machine manufacturer carefully takes into consideration the following
preconditions:
• This technical user documentation – including the documented limitations, safety
information and residual risks – is known and complied with.
• The plant or machine is carefully designed and engineered. A careful and thorough
acceptance test is then performed by qualified personnel and the results documented.
• All the measures required in accordance with the plant or machine risk analysis by means
of the programmed and configured Safety Integrated Functions or by other means are
implemented and validated.
The use of Safety Integrated does not replace the plant or machine risk assessment carried
out by the machine manufacturer as required by the EC machinery directive!
In addition to using Safety Integrated Functions, further risk reduction measures must be
Danger to life as a result of inactive Safety Integrated Functions after powering up
The Safety Integrated Functions are only activated after the system has completely powered
up. System startup is a critical operating state with increased risk. When accidents occur,
this can result in death or severe injury.
Carefully ensure that the machine is safe when the system runs up.
Danger to life as a result of undesirable motor motion when the system runs up and
the drives are activated after changing or replacing hardware and/or software
After hardware and/or software components have been modified or replaced, it is only
permissible for the system to run up and the drives to be activated with the protective
devices closed. Personnel shall not be present within the danger zone.
• It may be necessary to carry out a partial or complete acceptance test or a simplified
functional test after having made certain changes or replacements.
• Before personnel may re-enter the hazardous area, all of the drives should be tested to
ensure that they exhibit stable control behavior by briefly moving them in both the plus
and minus directions (+/-).
• When switching on carefully observed the following:
The Safety Integrated Functions are only available and can only be selected after the
system has completely powered up.
