MV use, it is designed for LV switchgears and for motor control center applications in both new and retrofitted installations. 3.1. Dimensions and installation AQ-101LV can be either door-mounted or panel-mounted in a standard 19 inch rack. The unit's dimensions are as follows: • Height: 177 mm (7.00") •...
3.3. Unit features AQ-101LV 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. 3.3. - 6. Arc protection unit AQ-101DLV. 3.4. Simplified block diagram The figure below presents the main components that can be found in both the AQ-101LV unit and the AQ-101DLV variant. Figure. 3.4. - 7. Simplified block diagram of AQ-101LV and AQ-101DLV.
4. Operation and configuration 4.1. LED indicator functions Both the AQ-101LV and its AQ-101DLV 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).
20 m, 25 m, 30 m, 35 m, 40 m). 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.
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. - 12. AQ-07 sensor with covered ends.
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.

Trip relays This unit has two (2) integrated trip relays for tripping circuit breakers, namely T1 and T2. Their type is normally open (NO).
7.2. Inputs 7.2.1. Arc sensor channels 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. S5 is the optional fiber optic loop sensor channel with a transceiver (Tx) terminal and a receiver (Rx) terminal.
If you want to have more information of these tests, please refer to the routine test reports sent with the AQ-101 unit and/or consult your nearest Arcteq representative for the type test reports.
