The current value always comes into the 103LV unit through BI1 and with the help of an external
current measuring device. Please note that there must not be any pulses within the HSO channel.
Additionally, synchronization output comes from BO1, while the input goes into BI1. BI2 trips T1–T4 as
well as AQD in all logic schemes. If BI2 is ON but the tripping criteria selected with the DIP switch is not
both light and current, only tripping can occur. BO1 sends a latched signal when something trips, and
both it and its LED stay on for ten (10) seconds if nothing tripped.
SS:0 (main)
All sensors trip all trip relays (T1–T4) as well as the high-speed output (HSO) and the AQD control.
When the blocking function is selected, it prevents all tripping activations apart from LED activations.
1) The binary input BI1 can be used to receive an external
curr
current
ent signal. The tripping criterion can be
selected to be light only (L>) or both light and current (L> + I>). When the current input function (SW1:
8) is OFF, the relay must receive both current and light signals simultaneously to be able to trip.
2) The AQD output does not work without a current signal, even when the relay is in the light-only
mode (SW1: 8 is ON).
SS:1 (main)
The sensors S1 and S2 do not activate the AQD control. All sensors trip all trip relays (T1–T4) as well
as the high-speed output (HSO). When the blocking function is selected, it prevents all tripping
activations apart from LED activations.
