Please note that to reconfigure a unit with fewer connections (BI/BO or sensors) than in the previously
memorized setup, one of the DIP switches must be moved back and forth once before the system
setup procedure is carried out. After this, you must wait one minute before you begin the new auto-
configuration sequence.
You can reconfigure a unit with more connections at any time without the wait and without having to
move one of the DIP switches.
4.3.2 Reset
All LED indications and latched trip relays can be reset by pressing the SET
SET push button for
one second.
Unless the button is pressed, the latched trip relays remain active until the auxiliary power is
disconnected. All LED indications also remain active even when the auxiliary power supply is
disconnected unless the button is pressed. Please refer to the "Non-volatile memory" chapter for more
information.
4.3.3 Input connection check
After the system setup (auto-configuration) procedure is completed, you can verify the connectivity of
all sensors and binary input channels by pressing the SET
SET push button three (3) times within two
(2) seconds. The LEDs of the corresponding sensors and binary input channels start blinking while the
"Power" LED is already blinking. The LEDs blink as many times as there are connected sensors and
binary output channels from other units.
4.4 DIP switch settings
The DIP switches are used to configure the unit's tripping logic and other functionalities. The various
trip schemes can be programmed easily by selecting the appropriate DIP switch positions, which
allows for more flexibility when changing the settings depending on the application. However, the most
convenient way to set the unit or a more complex arc protection system is to use Standard Arc
Schemes (SAS).
Tripping can be based on arc light only, or on both arc light and current thresholds, or on other tripping
criteria (such as undervoltage, etc.). Current threshold and other tripping criteria can also be applied to
BI1 to block tripping caused by natural light sources. The CBFP (circuit breaker failure protection)
scheme can also be enabled with the DIP switches. The DIP switch's pins 1…4 are used for selecting
schemes, and their numbering is based on binary arithmetic.
The DIP switches are located at the back of the unit for easy access. The figure below presents the DIP
switch numbering, and the table below that gives a detailed description of the settings.

NOTE!
TE!
Please note that while the pin numbers and their functions are the same for both AQ-101 and
AQ-101D, in the DIN rail variant of the unit the pins are "upside down" (that is, Pin 1 is at the
top of the DIP switch when normally Pin 8 is at the top)!
