Protective door with spring-loaded interlocking with an S7-1500
Monitoring the position of the protective door is performed via two SIRIUS 3SE5 position switches to reach the demanded safety level. If one position switch fails, an opened protective door is still detected by the second position switch. A failed position switch is detected by the discrepancy monitoring in the controller, and switching it back on is prevented until the failure has been removed.
