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