The T3 trip relays is always latched. The BO1 binary output function is always non-latched.
4.4.1 Scheme selection
This chapter describes the schemes that are available to this unit. The schemes are configured using
the DIP switches numbered 1…4 ("Scheme selection"). Most of the schemes are designed for double
busbar arc protection. For detailed instructions on each of the available schemes please refer to the
AQ-SAS™ booklet (can be found at
). 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
The schemes described below are the most important ones for this unit. However, additional schemes
are also available; please contact your nearest Arcteq representative for more information on
those schemes.
