The safety analysis of the guard locking function refers to the component solenoid interlock AZM as part of the complete
2
system.
On the customer side further measures such as safe actuation and safe cable installation to prevent faults are to be
implemented.
In the event of a fault resulting in the unlocking of the guard locking, this is detected by the solenoid interlock and the safety
gates Y1/Y2 switch off. When such a fault occurs the protection equipment may open immediately, just once, before the safe
condition of the machine is reached. The system reaction of category 2 allows that a fault can occur between tests causing the
loss of the safety function which is detected by the test.
The actuation of the interlock must be compared externally with the OSSD release. If a shut-down now occurs due to an
2
unintentional unlocking this is detected by an external diagnostic.
