Safety Integrated function
8.3 System features
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,
however, when the machine manufacturer is familiar with and observes every aspect of this
technical user documentation, including the documented general conditions, safety
information, and residual risks.
Precisely knows and observes this technical user documentation - including the
documented limitations, safety information and residual risks;
Carefully constructs and configures the machine/plant. A careful and thorough acceptance
test must then be performed by qualified personnel and the results documented.
Implements and validates all the measures required in accordance with the machine/plant
risk analysis by means of the programmed and configured Safety Integrated functions or by
other means.
The use of Safety Integrated does not replace the machine/plant 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
implemented.
The Safety Integrated functions cannot be activated until the system has been completely
powered up. System startup is a critical operating state with increased risk. No personnel
may be present in the immediate danger zone in this phase.
The drives of vertical axes must be in torque state.
A complete forced dormant error detection cycle is required after power on.
EN 60204-1:2006
Emergency Stop function must bring the machine to a standstill in accordance with STO.
The machine must not restart automatically after EMERGENCY STOP.
When the safety function is deactivated, an automatic restart is permitted under certain
circumstances depending on the risk analysis (except when Emergency Stop is reset). An
automatic start is permitted when a protective door is closed, for example.
