Safety Concept
Important Safety Considerations
The system user is responsible for:
•
the set-up, safety rating, and validation of any sensors or
actuators connected to the system.
•
completing a system-level risk assessment and reassessing the
system any time a change is made.
•
certification of the system to the desired safety performance
level.
•
project management and proof testing.
•
programming the application software and the device
configurations in accordance with the information in this
manual.
•
access control to the system, including password handling.
•
analyzing all configuration settings and choosing the proper
setting to achieve the required safety rating.
IMPORTANT
When applying Functional Safety, restrict access to qualified,
authorized personnel who are trained and experienced.
ATTENTION
When designing your system, consider how personnel will exit
the machine if the door locks while they are in the machine.
Additional safeguarding devices may be required for your
specific application.
ATTENTION
A HIM module may be used to configure and monitor the
MSR57P speed monitoring safety relay. However, the stop
button on the HIM does not have safety integrity and must not
be used to execute a safe stop.
The stop button setting is not maintained through a power
cycle. Do not use the stop button in conjunction with an
Automatic Reset configuration. Unintended motion could result.
