3.1 Unit features AQ-101 is a multipurpose arc flash protection unit and can be applied to a variety of applications. It can be used on its own as a stand-alone unit, or it can be a part of a more complex arc protection system through a binary bus.
Figure. 3.1 - 1. Arc protection units AQ-101 (left) and AQ-101D (right). 3.2 Dimensions and installation AQ-101 can be either door-mounted or panel-mounted in a standard 19 inch rack. The unit's dimensions (without cards) are as follows: • Height: 157 mm (6.18 in) •...
Figure. 3.2 - 3. Dimensions of the DIN rail variant of the device. The following image illustrates how a unit is installed into a cut-out. Please note that as AQ-101 is narrower than the unit in the image, they are connected to the cut-out panel by a single screw on both the top and the bottom of the front panel instead of the two depicted below.

-101 (AQ Q -101D -101D) ) Instruction manual Version: 2.01 The figure below presents the main components that can be found in both the AQ-101 unit and the AQ-101D variant. Figure. 3.3 - 5. Simplified block diagram of AQ-101 and AQ-101D. NOTE! Please note that the latching (or non-latching) of trip relays T1 and T2 is determined with the DIP switch (SW1:6).
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.
DIP switches numbered 1…4 ("Scheme selection"). For detailed instructions on each of the available schemes please refer to the AQ-SAS™ booklet (can be found at arcteq.fi/downloads/). Please note that there are four booklets: two are for schemes based on IEC standards (MV and LV versions) and the other two for schemes based on ANSI standards (MV and LV versions).
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.
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).
7 ms, as that is dependent on the device feeding the I> signal to the AQ-101 (or AQ-101D) unit. Please note that the S1 sensor channel can be set to operate solely on the light condition, even if other channels are set to operate on both conditions.
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.
8.2 Inputs 8.2.1 Arc sensor channels Both AQ-101 and AQ-101D 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. S5 is the optional fiber optic loop sensor channel with a transceiver (Tx) terminal and a receiver (Rx) terminal.
2. Connect one of the test set's outputs to a strong camera flash to initialize the flash and to configure the set's timer to start simultaneously with the flash. 3. Connect one of the AQ-101 unit's trip outputs (T1, T2, T3, T4) to a test set input and configure the input to stop the timer.
