2.3.3 I/O DESCRIPTION
AQ110P
AQ101
I/O Description
IL1 / IL2 / IL3 /
Io
Current inputs Phase IL1, IL2, IL3 and E/F Io, measuring current for
incomer.
BI1
Receive L> light signal from connected AQ110P
BI2
Receive L> light signal from connected AQ101.
In scheme 1a, 2a, it counts the amount of connected AQ101 units while
supervising each BO1 connections from AQ101 units.
In scheme 1b, it excludes the counting function and triggers the
supervision alarm (SF relay) when loss of all connected AQ101 units.
S1
Detect arc flash light for incomer cable compartment.
S2 /S3 /S4
Detect arc flash light for
• incomer switching device and cable compartment
• feeder busbar compartment and cable compartment.
HSO1
Send I> overcurrent signal to connected AQ101 units;
In normal operation, it is used to synchronize all connected AQ101
units.
HSO2
Send MT signal to connected AQ101 units; When it activates, the
connected AQ101 units activate T1 and T2 trip relays.
BO1
Send sensor channel (S1, S2, S3, S4) and binary input (BI2) L> signal
to connected AQ110P.
T1
Trip relay for incomer circuit breaker.
T2
Trip relay for incomer upstream circuit breaker.
T3 /T4
Trip relays mainly for fault location identification.
BI1
Receive I> overcurrent signal from connected AQ110P.
BI2
Receive MT signal from connected AQ110P.
S1/S2/S3/S4
Detect arc flash light for feeder busbar compartment, switching device
compartment and cable compartment.
BO1
Send sensor channel (S1, S2, S3, S4) to connected AQ110P.
In normal operation, it is used to send feedback pulse to connected
AQ110P.
T1/T2
Trip relay for feeder circuit breaker or bussectionalizer circuit breaker if
available.
T3/T4
Trip relays mainly for fault location identification.
