3.8. FAULT port (equipment self-diagnosis)
The rear panel FAULT connector (10) is a NO / NC dry contact linked to the self-diagnosis function of the
unit. This function measures from time to time if each amplifier channel is indeed working properly and delivering
the correct amplified program to its output terminals. If the test result is correct, i.e. if the amplifier is perfectly
operating, the FAULT contact remains at its default position, adopted immediately after the boot sequence. If, on
the contrary, and for whatever reason, the amplifier is not functional or is not correctly operating, the FAULT
contact toggles (a closed contact opens and an opened contact closes).
Thus, an external device can monitor whether a NXA device is working properly or not, and in the latter
case it can report the fault and / or switch to a redundant equipment.
You can activate this function from the EclerNet Manager application and determine the integrity test
frequency (every minute, every hour, etc.).
