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.
green (Power)
yellow (Status)
red (Fault)
System condition
No input signal at X1 and/or X2
Safety guard open and a safety guard in the safety circuit upstream is also open
Safety guard closed and a safety guard in the safety circuit upstream is open
Safety guard locked and a safety guard in the safety circuit upstream is open
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.
Fault warning
A fault that does not immediately endanger the safety function of the safety switchgear (e.g. too high ambient
temperature, safety output at external potential, cross-circuit) leads to delayed shutdown (see Table 2). This signal
combination, diagnostic output disabled and safety channels still enabled, can be used to stop the production process
in a controlled manner. An error warning is deleted when the cause of error is eliminated. If the fault warning remains
on for 30 minutes, the safety outputs are also switched off (red LED flashes, see Table 2).
