5.5 Status signal "safety release"
The "safety release" status signal from a Safety at Work slave can be
cyclically queried by the control system through the AS-i master. To that
effect, the 4 input bits with the varying SaW code of a Safety at Work
slave are evaluated through an OR operation with 4 inputs in the control
system.
6. Diagnostic
6.1 LED display
The solenoid interlock signals the operational state as well as errors
through three coloured LED’s installed on the front side of the device.
The LED's have the following meaning (to EN 62026-2):
LED red/green
(AS-i duo LED):
AS-Interface supply voltage /
AS-Interface communication error
or slave address = 0

Fault
Status
Error
Errors, which no longer guarantee the function of the AZM 200 AS
solenoid interlock (internal error)s cause the safety outputs to be
disabled within the risk time. Any error that does not immediately affect
the safe functionality of the AZM 200 AS (e.g. the ambient temperature
too high) will lead to a delayed shut-down (refer to table 2). After fault
rectification, the error message can be reset by opening and closing
the relevant guard door. The safety outputs of the safety monitor can be
switched back on, thus enabling the machine.
Error warning
If a fault has occured, which still guarantees the function of the
AZM 200 AS solenoid interlock, the system is safely switched off after
30 minutes. The safety outputs of the safety monitor initially remain
enabled. The error message can be read out through the parameter
port (refer to Table 1). Depending on the type of fault, the machine is
not immediately shut down. The control system obtains a preliminary
message, which can be used to shutdown the process in a controlled
manner. An error warning is deleted/reset as soon as the error cause
is eliminated.
