    Figure. 4 - 1. Arc protection devices AQ-101 (left) and AQ-101D (right). The AQ-101 is designed according to the latest protection relay standards and is therefore suitable for installations in rough environments. These include utilities and power plants (both traditional and renewable), various heavy industry applications (off-shore, marine, oil, gas, mining, steel, etc.) as well...
  • Page 10 5 Device features AQ-101 is an arc flash protection device which can be applied to a variety of applications. It can be used on its own as a stand-alone device, or it can be a part of a more complex arc protection system by using binary inputs and outputs to connect multiple AQ 100 series devices together.

    Figure. 6.2.1 - 5. Arc point sensor connections Both AQ-101 and AQ-101D have four (4) arc point sensor channels: S1, S2, S3 and S4. Up to three (3) arc point sensors can be connected to each channel. When the arc protection system has been set up, point sensor connections are constantly monitored.

  • Page 15: Outputs

    AQ 100 series device's binary outputs send out a short pulse every second. Binary inputs of the receiving AQ 100 series devices use these pulses to count the number of connected binary outputs. System self-supervision chapter for more information. NOTICE! TICE! Please note that the binary ouputs are polarity-sensitive. © Arcteq Relays Ltd IM00006...

  • Page 16: Trip Relays

    Whenever the device detects a system error or the auxiliary power supply is disconnected, the SF relay changes its state. The state stays this way until the device returns to a healthy condition. See the System self-supervision chapter for more information. © Arcteq Relays Ltd IM00006...

  • Page 19: Arc Light And Pressure Point Sensor Aq-02

    AQ-07 is an arc light fiber optic loop sensor, which is a robust fiber optic cable with a practically unlimited bending radius. The sensor contains hundreds of glass fiber drains covered by a plastic tube, thus making it extremely strong and durable. Fiber sensors are distributed through the protected switchgear cells. © Arcteq Relays Ltd IM00006...

  • Page 20: Arc Light Fiber Optic Loop Sensor Aq-08

    If necessary, the ends of an AQ-07 cable can be ordered with heat shrinking tubing to avoid light detection outside the protected zone. The covered area can be one (1) or two (2) meters by default; if other lengths are required, please consult the Arcteq sales team. You can find the Contact and reference information page at the end of this manual.

    NOTICE! TICE! Please note that while the switch numbers and their functions are the same for both AQ-101 and AQ-101D, in the DIN rail variant of the device the switches are "upside down" (that is, switch 1 is at the top of the DIP switch when normally switch 8 is at the top)! Figure.

    8.2 Available logic schemes The schemes described below are the most commonly used ones for AQ-101 devices. However, additional schemes are also available; please contact your nearest Arcteq representative for more information on those schemes. The schemes are configured using the DIP switches numbered 1…4 ("Scheme selection").

    8.5 LED indicator functions Both the AQ-101 and its AQ-101D variant have twelve (12) indication LEDs on the device's front panel. 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.
