4.4.1. Scheme selection
This chapter describes the schemes available for both variants of the unit. The schemes are configured
using the first DIP switch (SW1) and its pins 1…3 ("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).
4.4.2. Available logic schemes
Below you can see descriptions of all the logic schemes available to the AQ-103LV unit. The basic logic
is the same in all the logic schemes: BO1 and BI2 are always tripped by light (L>), whereas BI1 is
always tripped by overcurrent (I>). Regardless of the selected logic scheme, BO1 activates whenever
the sensors S1–S4, S5, S6–S15 or BI2 activates. You can select between light-only tripping and light-
and-overcurrent tripping with DIP switch 1 (SW1: 8). This selection affects all trip relays (T1–T4) as well
as the high-speed output (HSO). This is also true of the DIP switch that determines latching (SW1: 6).
