4.4 Current threshold settings The AQ-110x units have four (4) current measurement inputs: three (3) measure phase currents and one (1) measures the residual current. Both the phase and residual current measurements are used as secondary trip criteria in an arc protection system to avoid trips caused by natural light sources.

Page 30: 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. © Arcteq Relays Ltd IM00009...
Page 31 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. © Arcteq Relays Ltd IM00009...

8.2 Inputs 8.2.1 Current measurement inputs Both AQ-110x variants have four (4) CT inputs for measuring the three phase currents and the residual current. Both the phase current and the residual current inputs can be configured to a nominal current of 1 A or 5 A with the DIP switches (for more information, please refer to the "DIP switch settings"...
Page 42: Binary Inputs
The binary inputs are activated when a connected DC signal exceeds the specified nominal threshold level of the corresponding input. The nominal threshold level for AQ-110x units is 24 VDC. Please note that the actual activation of the binary input occurs earlier than the specified nominal threshold value (see Chapter 11.5, "Techical Data").
