IQ. URC can supply these control power transformer (CPT) kits. Contact URC for
more informaon.
The Breaker-IQ can be connected to temporary USB power via the rear Aux USB
port or to the side miniUSB port. If power only (without any URC USB
communicaon) is supplied to either of these USB ports, then the Breaker-IQ
will automacally disconnect power aer a period of inacvity.
4.4 Location and Distance from Breaker
The Breaker-IQ is intended to be installed on the switchgear door, immediately
adjacent to the circuit breaker trip unit. The standard cable length is 60
inches (5 feet). Addional lengths up to 15 feet are available to order.
5.0 Screen Navigaon
The Breaker-IQ user interface allows navigaon of trip units using same

generally known as an Energy Reducing Maintenance Switch (ERMS). It can be
used to reduce trip mes when turned on, and allows selecve coordinaon when
turned off. For more informaon about the Quick-Trip system, see
www.ulityrelay.com.
6.2.1 Quick-Trip Control
The Breaker-IQ can be used to control the Quick-Trip On/Off mode. This control
can be accomplished in several ways:
· Touchscreen control (Security Code required).
· Oponal physical pad-lockable QT-Switch is available from URC.
· Exisng QT2-switch (if already installed) · Remote QT-switch · InfoPro-AC
soware connecon to USB port
IMPORTANT: For operaonal consistency, use of only one method is strongly
recommended.
The Quick-Trip screen is accessible from the main
IMPORTANT: the operator must confirm the Breaker-IQ Quick-Trip (QT) LED is ON.
This posively indicates that the connected trip unit is in Quick-Trip mode.
6.2.2 Quick-Trip Indication The Breaker-IQ provides posive indicaon of the
Quick-Trip (QT) state of the connected trip unit. The Breaker-IQ provides this
indicaon via a dedicated Quick-Trip LED, which can be programmed to be Red or
Blue. In addion, the Breaker-IQ will display a flashing “Quick-Trip ON”
screen.

programmed and wired to send a QT ON signal to a remote LED or system, using
one of its programmable output contacts.
screen buton or from the configuraon menu
buton. Both paths require Security Code entry. (last 4 digits of Breaker-IQ serial number).
Figure 26: QUICK-TRIP screen
To Change the Quick-Trip (QT) State: Tap the ON or OFF touchscreen butons. If
the Security code has already been entered successfully during the present
user session, then the Security code screen will be displayed, and the QT
state will change immediately. If the Security code was not yet entered
successfully during the present user session, then the Security code screen
will appear and once it is entered successfully, the QT state will change.

6.2.3 Remote QT Control and Indication With addional customer field wiring,
the Breaker-IQ is capable of Quick-Trip control and indicaon from/at a remote
locaon. See the Installaon secon of this manual for an example diagram showing
Remote Quick-Trip connecons.
NOTE: If the QT2-Switch is used, then v4 or later ACPRO-II firmware must be
present for Breaker-IQ touchscreen control of Quick-Trip mode.

6.3 Breaker Control
Breaker-IQ® is capable of iniang a manual Trip and manual Close command,
including a user-set me delay (0-30 seconds) if the command is iniated by the
user at the front panel. This me delay allows the user to safely move away
from the breaker before it operates.
When at the main screen, tap the Configuraon
menu buton
. The Security Code entry screen
will appear (unless the Security Code has already
been successfully entered during the same user
session). Once the code is successfully entered, tap
the
buton.
The following screen will be displayed.
6.3.1 Delayed Trip
The Trip command trips the breaker via a signal to the trip actuator. This
occurs via a USB communicaons command from Breaker-IQ to ACPRO-II. The breaker
must be closed for the Trip command to be praccal or available. In addion, the
Actuator circuit must be complete (not open) for the command to be available.
For these trips, trip data is recorded, including date/me, RMS values, and
breaker mechanism me. Recording of the breaker mechanism me is part of URC’s
Sluggish Breaker Detecon® feature. These trips are logged as “Safe-T-Trip”
trip type. When the trip command is executed, all other Breaker-IQ
communicaons will cease while the handshake and command between the Breaker-IQ
and AC-PRO-II is executed. This includes LED status.
To execute a delayed trip command: 1. Navigate to the Breaker Control screen
(shown in previous secon of this manual).
2. Use the
and
butons
to select the desired delay (to allow for
walking a safe distance away). The delay
range is 0-30 seconds.
Figure 29: Breaker Control screen
Note: The Trip and Close butons will be displayed or hidden, depending on the
breaker posion, the Breaker-IQ sengs, and the trip unit sengs.
3. Tap the
buton.
4. Ensure all safety precauons are taken and
confirm you want to Trip the breaker by
tapping “Yes”. (see screenshot in this
secon).
5. The delay countdown will begin. (see
screenshot in this secon) Walk away to a
safe locaon.

6.3.2 Delayed Close
The Close command sends a signal to the exisng breaker close coil (or spring
release). This can be accomplished in two different ways:
Opon 1: Breaker-IQ Output 2 is wired into the close circuit: In this opon, the
Breaker-IQ outputs a signal that is wired to a close relay and then wired to
the close circuit in the switchgear.
This opon may be preferred in applicaons where breaker control power is
available on or near the switchgear door, since the new wiring into the close
circuit occurs in the switchgear.
See the Installaon secon of this manual for wiring diagrams showing Breaker-IQ
wired into the close circuit. See the Outputs and Sengs secon of this manual
for sengs instrucons. (Output 2 must be programmed for “Close Bkr”.) Contact
URC for close relay opons.
Opon 2: AC-PRO-II is wired into the close circuit: In this opon, the Breaker-
IQ sends a communicaons command via USB to the AC-PRO-II. The AC-PRO-II must
have v4 firmware or later, must be wired into the close circuit on the
breaker, and must be and programmed accordingly.
To execute a successful close operaon, the breaker must be equipped with a close coil, must have close control voltage present, and the close circuit must be wired properly through the AC-PRO-II or the BreakerIQ. In addion, the breaker must be open and either the trip unit OR the Breaker-IQ sengs must be programmed properly.
To execute a delayed close command: 1. Navigate to the Breaker Control screen (shown in the previous secon of this manual).
2. Use the
and
butons
to select the desired delay (to allow for
walking a safe distance away). The delay
range is 0-30 seconds.
3. Tap the
buton.
4. Ensure all safety precauons are taken and
confirm you want to Close the breaker by
tapping “Yes”. (see screenshot in this
secon).
5. The delay countdown will begin. Walk away
to a safe locaon.
This opon may be preferred in applicaons where the customer prefers the new close circuit wiring to occur on the breaker.
See the AC-PRO-II Instrucon manual for an example wiring diagram of AC-PRO-II wired into the close circuit, and for related AC-PRO-II sengs. htps://ulityrelay.com/PDFs/Product_Manuals/I-ACPRO-II.pdf Contact URC for close relay opons.
Notes: 1.
If both the AC-PRO-II and Breaker-IQ are programmed for the Close breaker feature, then the signal is sent via Breaker-IQ.

6.5 Wireless Comm & Settings
The BREAKER-IQ® is capable of Wireless communicaons with a Windows PC with a
URC Wireless dongle and URC InfoPro-AC soware applicaon.
A USB Wireless dongle is available from URC. This device can be used to allow a Windows PC to wirelessly communicate with BREAKER-IQ.
When the connecon is established and authencated, InfoPro-AC soware is capable of all funcons (same funcons as USB cable connecon).
For wireless communicaon to be acve, the Wireless (circuitry) switch on the
back of the unit must be ON, and the user must enable wireless communicaon
using the front screen and butons.
Establishing a wireless connecon is a secure process, including generaon and
entry of unique 6digit PIN. The unique PIN is randomly generated each me per
industry standard security methods. In addion, in the process of enabling the
wireless feature, the user sets a “Timeout” (idle meout) seng each me a
wireless session is started. The idle mer starts when communicaon is not
occurring. The idle mer is reset when communicaon occurs. If the mer reaches
the user set “meout”, the radio will be disabled (Mode switches to OFF).
The wireless (circuitry) switch on the back of the BREAKER-IQ allows the
wireless radio circuitry to be switched “ON” or “OFF”. The switch is not
accessible aer the BREAKER-IQ is installed. When the switch is in the “ON”
posion, it simply means the feature is capable of being turned ON by the user:
The radio is “OFF”, unless the user enables the feature using the front screen
and butons. (when the radio is actually ON, the (blue) Wireless LED will
flash). When the switch in the “OFF” posion: The radio circuitry is disabled
and the feature is not accessible using the front screen and butons. URC
recommends installing the BREAKER-IQ with the wireless switch “ON”, unless the
facility does not permit such features.
USB Wireless dongle (available from URC)
Wireless security notes:
The BREAKER-IQ is designed for “Secured Connecon Only Mode” (“Secure Mode 1”
with “Security Level 4”) meaning all incoming and outgoing traffic involves
authencated connecons and encrypon. Any device trying to connect that doesn’t
support secure connecons is disconnected.
Presently, pairing is required every me a connecon is established. The user
must be at the Breaker-IQ to view the PIN.
Wireless communicaons will cease (Mode will automacally switch to OFF) if URC
communicaons does not occur for a certain period of me (idle meout described
elsewhere in this secon). In addion, there are several means of disconnecng
and/or disabling wireless communicaons as described elsewhere in this Secon.
The next page includes instrucons for establishing a wireless connecon with
BREAKER-IQ.
The Wireless (blue) LED flashes “fast” (mulple flashes per second) when the unit is “adversing” or “pairing”. This occurs when the radio is on, but the BREAKER-IQ is not yet connected to anything, or was disconnected. The LED flashes “slow” (about 0.5 sec ON, 0.5 sec OFF) when a secure connecon is established.
