SS:4
1) If the blocking function (SW1: 5) is ON, the activation of BI1 blocks all trip output signals.
2) If the blocking function (SW1: 5) is OFF, the binary input BI1 can be used to receive an external
current signal. The tripping criterion can be selected to be light only (L>) or both light and current (L> +
I>).
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.
