Normal operation mode
System supervision
Arc detection
After initialization process, the system enters normal operation mode.
In the normal operation mode, the master executes two parallel tasks:
1. System supervision
2. Arc detection
In normal operation mode the master executes a cyclic self-check and the presence of
all configured modules. If an error is detected an appropriate system error event will
be activated and watchdog relay will be activated. For details see list of “2.7 Events &
Alarms”. Acknowledgment of system error is possible only if error source is deactivated.
After acknowledging of all detected system errors, the watchdog relay output will be
deactivated again.
