    Figure. 3 - 1. Arc protection device AQ-101S. The AQ-101S 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 as commercial and institutional electrical systems.
  • Page 11 4 Device features AQ-101S is an arc flash protection device which it can be applied to a variety of applications that require a large amount of data communication. 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.

    5.2.1 Arc sensor channels Figure. 5.2.1 - 4. Arc point sensor connections AQ-101S has 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.

  • Page 15: Outputs

    5.3.1 Binary outputs Figure. 5.3.1 - 6. Binary output connections AQ-101S has three (3) binary outputs: BO1, BO2 and BO3. AQ 100 series binary outputs have an internal 24 VDC power supply. Binary outputs are used for sending overcurrent, light detection, master trip and other signals to other AQ 100 series devices in the same system.
