2.2 POTENTIOMETERS (AQ110P ONLY)
Current pick-up setting (set point) is done with potentiometers on the back side of
the device. Use flat head screw driver for moving the potentiometer to the desired
set point. See chapter 4.1.2 for accurate setting of the current activation level.
Figure 2-1: Current pick-up potentiometers.
2.3 SIEMENS PROTECTION SCHEME LOGICS (AQ101, AQ101D, AQ110P)
Following tables describes the basic functionality of scheme 0 (AQ101, AQ101D),
scheme 1a, 1b and 2a (AQ110P).
Following tables doesn’t segregate the light and light + current mode trip settings.
In case light and current mode has been chosen with dip switches, corresponding
sensor activation requires simultaneous overcurrent injection. For the CBFP
operation, refer to the relevant dipswitch settings.
Activation table letters:
X = activation of output when signal is active
C = output activates according to the CBFP functionality
Y = output activation has more than one function depending on the
setting of CBFP function. See dip switch settings on chapter 2.1.
For C and Y activation, refer to the scheme logic tables
Table 2-5 and Table 2-6.

*) S5 is optional and may be used as fiber optic sensor input or quenching device control. Refer to
the technical manual and ordering codes.
**) T3 and T4 are mainly for fault location identification.
***) When DIP switch SW2:4 is set to FAST mode, the trip relay T2 is activated without CBFP
function. When DIP switch SW2:4 is set to CBFP mode, the CBFP function activates trip relay T2 if
sensor channel (S2, S3, S4) or L> input (BI1, BI2) is activated for more than CBFP set time (100ms
or 150ms).

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.
