Periodic Checks
Safety switches should be checked at each shift change or machine setup by a designated person for:
1. Breakage of the switch body or actuator,
2. Good alignment and full engagement of the actuator with the receptor,
3. Confirmation that the safety switch is not being used as an end stop,
4. Loosening of the switch or actuator mounting hardware, and
5. Verification that it is not possible to reach any hazard point through an opened guard (or any opening) before hazardous machine
motion has completely stopped.
In addition, a qualified person should check for the following on a periodic schedule determined by the user based upon the severity of
the operating environment and the frequency of switch actuations:
