Note about the safety classification
2
The safety consideration of the guard locking function only applies for standard devices with
monitored solenoid interlock AZM300Z-…-1P2P-… (see Ordering code). A safety assessment of the
guard locking function for devices with serial diagnostics "SD2P" is not allowed due to the non-safe
locking/unlocking signal from the SD Gateway.
2
If for a certain application the power to unlock version of a solenoid interlock cannot be used, for this
exception an interlock with power to lock can be used if additional safety measure need to be realised
that have an equivalent safety level.
2
The safety analysis of the guard locking function refers to the component solenoid interlock AZM as
part of the complete 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.
2
The actuation of the interlock must be compared externally with the OSSD release. If a shut-down now
occurs due to an unintentional unlocking this is detected by an external diagnostic.
