    4. Operation and configuration 4.1. LED indicator functions Both variants of the AQ-103LV unit have twenty-five (25) 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 sheet located in the transparent pockets next to the LEDs.

  • Page 20: Scheme Selection

    4.4.2. Available logic schemes Below you can see descriptions of all the logic schemes available to the AQ-103LV unit. The basic logic is the same in all the logic schemes: BO1 and BI2 are always tripped by light (L>), whereas BI1 is always tripped by overcurrent (I>).
  • Page 21 The sensors S1 and S2 do not activate the AQD control. All sensors trip all trip relays (T1–T4) as well as the high-speed output (HSO). When the blocking function is selected, it prevents all tripping activations apart from LED activations. © Arcteq Relays Ltd...
  • Page 22 (L>) or both light and current (L> + I>). When the current input function (SW1: 8) is OFF, the relay must receive both current and light signals simultaneously to be able to trip. © Arcteq Relays Ltd...

  • Page 23: Non-Volatile Memory

    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...

  • Page 26: Arc Light Fiber Optic Loop Sensor Aq-07

    When requested, the ends of an AQ-07 cable can be covered with black rubber to avoid light detection outside the protected zone (see the figure below). The covered area can be as large or small as necessary. For more information, please consult your nearest Arcteq representative. Figure. 5.4. - 13. AQ-07 sensor with covered ends.

  • Page 27: Arc Light Fiber Optic Loop Sensor Aq-08

    It is not recommended to cut or splice the cable on-site. However, if cutting or splicing is necessary due to the cable breaking, please contact your nearest Arcteq representative for instructions. The fixed light intensity threshold of an AQ-08 sensor is 8,000 lux. The sensor does not require further settings by the user.

  • Page 28: Connecting Sensors

    Please note that AQ-07 and AQ-08 glass fibers can be covered with additional tubing, if the fiber sensor's placing requires the blocking of unwanted light activation. For more detailed instructions on both the installation and the tubing processes, please refer to the "Connecting sensors" chapter in the AQ-0x instruction booklet (arcteq.fi/downloads). © Arcteq Relays Ltd...
