    4 Operation and configuration 4.1 LED indicator functions Both the AQ-101 and its AQ-101D variant have twelve (12) indication LEDs. Apart from the "Power" and "Error" LEDs, the user can write their own identifications for each of the remaining LEDs on the text insert located in the transparent pocket next to the LEDs.

    Then, all LEDs are turned off. Additionally, the DIP switch setting are stored in the non-volatile memory during this sequence. All sensor inputs remain operational even when they have not been auto-configured. System setup is only used for self-supervision purposes. © Arcteq Relays Ltd IM00006...

    NOTE! Please note that while the pin numbers and their functions are the same for both AQ-101 and AQ-101D, in the DIN rail variant of the unit the pins are "upside down" (that is, Pin 1 is at the top of the DIP switch when normally Pin 8 is at the top)! ©...

    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 IM00006...

    Version: 2.01 6 System self-supervision All AQ-101 and AQ-102 variants (that is, both LV and MV) have an extensive self-supervision feature, including both internal functions and external connections. The self-supervision module monitors the power supply, hardware and software malfunctions, as well as problems with the binary input connection(s) and sensor(s).

    Version: 2.01 7.2 Wind power application (light only) AQ-101 and AQ-101D can be applied by using arc light as the only tripping criterion. This example application describes a typical wind power scheme, where a permanent magnet synchronous generator is applied with a converter cabinet and an MV/LV transformer.

    Version: 2.01 7.3 Circuit breaker failure protection All AQ-101 variants include a selective circuit breaker failure (CBFP) function, which can be enabled through the DIP switch settings (please refer to the "DIP switch settings" chapter for more information). When enabled, the CBFP function activates when the tripped breaker fails to operate, or if the unit detects the presence of light after a set operating time.
