    Figure. 3 - 1. Arc protection device AQ-101LV (left) and AQ-101DLV (right). The AQ-101LV 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 4 Device features AQ-101LV 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. 5.2.1 - 5. Arc point sensor connections Both AQ-101LV and AQ-101DLV have four (4) arc point sensor channels: S1, S2, S3 and S4. You can connect a maximum of three (3) arc point sensors to each channel. When the arc protection system has been set up, point sensor connections are constantly monitored.

    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.
