BUTTON DESCRIPTION
AQ 110 contains one single push-button (SET) that can be used for all
operational functions of the unit. The push-button is utilized for auto-configuration
of the system (see chapter 3.3.1) and for resetting the indicators and latched
output relays.

A
UTO CONFIGURATION
(
SYSTEM SETUP
)
When all current circuits, sensors and binary lines have been connected an auto-
configuration procedure must be executed. The initialization sequence is
performed by pressing the “SET”-button for 2 seconds, and the AQ 110 sensor
LEDs and BI1/BI2 LEDs start blinking. The unit scans these inputs to see if they
are connected and when input is detected the corresponding LEDs are lit up to
mark that a connection was found. The inputs without connection continue
blinking during the remaining 3 seconds. After total time of 5 seconds, all LEDs
are turned off. During this system setup the dipswitch setting are also stored in
non-volatile memory.
All sensor inputs will remain operational even when not auto-configured. The
auto-configuration is only used for self-supervision purposes.

R
ESET
All LED indications and latched trip relays are reset by pressing the “SET”-button
for 1 second. Otherwise the latched trip relays will remain activated until auxiliary
power is disconnected. All LED indications will remain active until reset is
performed by operator even in case of disconnecting auxiliary power supply (see
chapter 3.7 Non-volatile memory).
