1.0 GENERAL-The IQ-1000 11™ is a self-contained,
door-mounted, motor protection device which may be
applied to 50 Hz or 60 Hz 3-phase motor starters or
switch gear, including low-, medium-, and high-voltage
equipment.
The IQ-1000
II monitors 3-phase AC motor currents to
develop
an accurate thermal model of motor heating. A
separate RTD Module option allows the IQ-1000 II to
combine the monitored motor stator temperature with the
motor current information. The resulting combination of
data allows the IQ-1000 II to develop a more detailed pic-
ture of the motor's temperature, thereby maximizing
motor utilization.
The IQ-1000
11 operates by monitoring motor current, and
takes the motor off-line when it detects a problem such
as an overcurrent or over temperature condition. If an
operating parameter exceeds its setpoint value, the IQ-
1000 II initiates a trip condition.
1.1 CONTENTS/USE OF MANUAL -This manual
contains the following sections:
A- IQ-1000 To IQ-1000 II Upgrade.
1 - Introduction.
2 - Hardware Description. Itemizes the hardware fea-
tures and lists the specifications of the IQ-1000
II.
3 - Functional Theory. Describes how the hardware
and software function together to control, monitor, and
protect the motor.
4 - Operator Panel. Describes the uses of the Operator
Panel. Various operations such as loading setpoints or
examining metered data are described.
5 - Installation. Outlines the installation procedures to
be followed by a plant electrician or wiring crew when
installing the IQ-1000 II.
6 - Startup. Lists step-by-step procedures to follow
when first applying power to the IQ-1000
II.
7 -Application Considerations. Intended as an aid to
the application engineer considering how and when to
apply the various features of the IQ-1000 II. Hardware

INTRODUCTION
characteristics as well as set point and control back-
ground information are included.
8- Programming the IQ-1000 II And Set Point
Description. Lists the various application considerations
associated with each of the functions of the IQ-1000
11.
Available setpoint ranges or settings are detailed.
9 - Troubleshooting. Provides background information
on how to use the Operator Panel to recognize malfunc-
tions. Also, a specific troubleshooting approach is listed.
The manual is broad enough in scope for new employee
familiarization, refresher training sessions, and ongoing
maintenance, installation, troubleshooting and unit
replacement (if necessary) of the IQ-1000 11.
This manual contains information of specific importance
tor the user application engineer who is planning the
motorcontrol system and who is determining the setpoint
values for the IQ-1000 II.
It is strongly advised that the application engineer care-
fully read Sections 2 thru 8 before beginning the applica-
tion's Wiring Plan Drawings and Set Point Record Sheet.
Installation teams should carefully read all of Section 5,
Installation, and all previous sections, before starting final
installation. Maintenance personnel should be familiar
with Sections 2 thru 9 before attempting to service the
IQ-1000
II.
1.2 PRODUCT OVERVIEW -The IQ-1000 II offers 52
operating setpoints, each referred to as a function. The
setpoints associated with these functions are individually
entered through the Operator Panel located
on the front
of the IQ-1000
II.
The functions consist of the following types of entries:
• Alarm Relay condition settings. An Alarm Relay
closes when various conditions, such as motor cur-
rents or temperatures, exceed the selected setpoints.
The alarm serves as an early warning. The motor's
operation is not affected.
• Trip Relay condition settings. A Trip Relay closes
(or opens) when various conditions, such as motor
current or temperature, exceed separately selected
setpoints. Action of the Trip Relay is user-selectable.

Page 8
• Auxiliary Trip Relay condition setting. The auxil-
iary Trip Relay changes state when a user-selected
condition, such as Instantaneous Overcurrent,
exceeds a separately selected setpoint. Action of the
Auxiliary Trip Relay is user-selectable.
• Specific application-related information. Entries
such as the ratio of the current transformers or the
incoming
AC line frequency are required by the IQ-
1000
II to properly monitor the motor.
Together, the functions tailor the IQ-1000
11 for each spe-
cific application. After entry is completed, the setpoint
values can be examined or modified. The actual values
are stored in a non-volatile memory requiring no backup
batteries or special power supplies. In instances where a
particular function is not required, it can usually be
bypassed by entering a specific disable value.
1.3 OPTIONS -Options associated with the IQ-1000 11
consist of external hardware. The following options are
available:
• RTD Module Option. The RTD Module option is
required when resistance temperature devices (RTD)
are used to monitor motorwinding, load and/or motor
bearing temperatures. An auxiliary RTD connection
is provided on the RTD Module for monitoring one
additional location (such as motor case temperature).
• Communications Option. The IQ-1000 II can com-
municate motor data/status to a remote device such
as a computer with
an optional BPONI module over
the PowerNet network.
• IQ DC Power Supply -The IQ DC Power supply is
required only when 40 voe to 250 voe control
power is available.
1.4 EXTERNAL HARDWARE -The following items
are required
in addition to the IQ-1000 II.
• Current transformers. Current transformers are
used by the IQ-1000
II to obtain load current informa-
tion. Current transformers with 5 amp secondaries
and ratios ranging from 10:5 to 4000:5 can be used.
• Ground fault transformer. A ground fault trans-
former with a 50:5 ratio can be used with the IQ-1000
II in grounded system applications to provide ground
fault protection.
1.5 PROTECTION FEATURES -A list of protection
features with the IEEE device numbers is contained
in
Table 1.A.
TD 172970
1.6 LEVEL OF REPAIR -This manual is written with
the assumption that only unit-level troubleshooting will be
performed. If the cause of a malfunction is traced to the
IQ-1000
II unit, it should be replaced with a spare. The
malfunctioning IQ-1000
II should then be returned to
Cutler-Hammer for factory repairs.
1.7 FACTORY CORRESPONDENCE -All correspon-
dence with Cutler-Hammer, whether verbal or written,
should include the "software version" number. This num-
ber appears
in the display window when the Program
mode is first entered, or the program menu is first initi-
ated (this is item O in Table 8.B). The software version
number is used to identify the specific IQ-1000 II type
being discussed.

• Terminals 4 and 7 receive the incoming AC control
voltage.
• Terminal 5 is the chassis ground. A direct connection
must be made between terminal 5 and the main
ground bus to ensure proper operation.
• Terminal 6 can be jumpered to terminal 9 in order to
provide the common (AC neutral) for terminals 8 and
10.
• Terminal 8 is used with the remote trip/reset function.
It is the high side of a user-supplied 120 VAC signal
input.
• Terminal 9 is the AC neutral,
or common, wire associ-
ated with terminals 8 and 10.
• Terminal 10 is used with the incomplete sequence
report-back function. It is the high side of a user-
supplied input signal.
• Terminals
11 thru 23 provide access to the Trip, Aux-
iliary Trip and Alarm Relays' contacts,
as well as the
