2) The AQD output does not work without a current signal, even when the relay is in the light-only
mode (SW1: 8 is ON).
4.5. Non-volatile memory
All critical system data (such as DIP switch settings and the system setup file) are stored in the non-
volatile memory (EPROM) to ensure accurate operation and full self-supervision even if auxiliary power
is lost temporarily.
Additionally, all LED indications are stored in the non-volatile memory to provide a quick recovery of the
system status indication. This feature is especially important if tripping causes the unit to lose its
auxiliary power.
The non-volatile memory does not require a power supply to maintain the information and it retains the
settings and the indications permanently without power.
