Safety switches should be checked at each shift change or machine setup by a
designated person (see below) 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
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:
1. Check the wiring chamber for signs of contamination.
2. Check the contacts for signs of deterioration or damage.
3. Inspect the electrical wiring for continuity and damage.
4. Verify that wiring conforms to the instructions on pages 3 and 4 of this data sheet.
