6.1 Magnet control
In the power to unlock version of the AZM300, the solenoid interlock is unlocked when the IN signal (= 24V) is set.
In the power to lock version of the AZM300, the solenoid interlock is locked when the IN signal (= 24 V) is set.
6.2 Mode of operation of the safety outputs
In the standard AZM300Z variant, the unlocking of the solenoid interlock causes the safety outputs to be disabled.
The unlocked safety guard can be relocked as long as the actuator is inserted in the AZM300Z solenoid interlock; in
that case, the safety outputs are re-enabled.
It is not necessary to open the safety guard.
In the AZM300B version, only the opening of the safety guard causes the safety outputs to be disabled.
6.3 Diagnostic-LEDs
The solenoid interlock signals the operating condition, as well as errors through 3-colour LEDs.

6.4 Solenoid interlock with conventional diagnostic output
The short-circuit proof diagnostic output OUT can be used for central visualisation or control tasks, e.g. in a PLC.
The diagnostic output is not a safety-related output.
Error
Errors which no longer guarantee the function of the safety switchgear (internal errors) cause the safety outputs to
be disabled within the duration of risk. After fault rectification, the error message is reset by opening and re-closing
the corresponding safety guard.
