3. After 10 seconds, brief yellow cyclic flashes (3 Hz) request the switch-off of the operating voltage of the
solenoid interlock. (If the voltage is not switched off within 5 minutes, the solenoid interlock cancels the
"teach-in" procedure and signals a false actuator by 5 red flashes).
4. Once the operating voltage is switched back on, the actuator must be detected once more in order to
activate the actuator code that has been taught in. In this way, the activated code is definitively saved!
For ordering suffix -I1, the executed allocation of safety switchgear and actuator is irreversible.
For ordering suffix -I2, the "teach-in" procedure for a new actuator can be repeated an unlimited number of times.
When a new actuator is taught, the code, which was applicable until that moment, becomes invalid. Subsequent to
that, an enabling inhibit will be active for ten minutes, thus providing for an increased protection against tampering.
The green LED will flash until the expiration of the time of the enabling inhibit and the detection of the new
actuator. In case of power failure during the lapse of time, the 10-minutes tampering protection time will restart.
6 Active principle and diagnostic functions
6.1 Magnet control
In the power to unlock version of the AZM201, the solenoid interlock is unlocked when the IN signal (= 24V) is set.
In the power to lock version of the AZM201, 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 AZM201 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 AZM201 solenoid interlock; in
that case, the safety outputs are re-enabled.
It is not necessary to open the safety guard.
In the B-variant AZM201B, the opening of the safety guard causes
the safety outputs to be disabled.
6.3 Diagnostic-LEDs
Die Sicherheitszuhaltung signalisiert den Betriebszustand, aber auch Störungen, über drei verschiedenfarbige LEDs
auf der Frontseite des Gerätes.
green (Power)
yellow (Status)
red (Fault)
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
