!
CAUTION
COMPLETELY READ AND UNDERSTAND THE
MATERIAL PRESENTED IN THIS DOCUMENT
BEFORE ATTEMPTING INSTALLATION, OPERATION
OR APPLICATION OF THE EQUIPMENT. IN ADDITION, ONLY QUALIFIED PERSONS SHOULD BE
PERMITTED TO PERFORM ANY WORK ASSOCIATED WITH THE EQUIPMENT. ANY WIRING INSTRUCTIONS PRESENTED IN THIS DOCUMENT MUST BE
FOLLOWED PRECISELY. FAILURE TO DO SO
COULD CAUSE PERMANENT EQUIPMENT DAMAGE.
1.2 BACKGROUND
Transfer switches are used to protect critical electrical
loads against loss of power. The load’s normal power
source is backed up by a secondary (emergency) power
source. A transfer switch is connected to both the normal and emergency sources and supplies the load with
power from one of these two sources. In the event that
power is lost from the normal source, the transfer switch
transfers the load to the secondary source. Transfer can
be automatic or manual, depending upon the type of
transfer switch equipment being used. Once normal
power is restored, the load is transferred back to the
normal power source.
In automatic transfer switch equipment, the switch’s
intelligence system initiates the transfer when normal
power fails or falls below a preset voltage. If the emergency source is a standby generator, the transfer switch
initiates generator starting and transfers to the emergency source when sufficient generator voltage is available. When normal power is restored, the transfer
switch automatically transfers back and initiates engine
shutdown.
I.B. ATS-I005
Page 2
An automatic transfer switch consists of three basic elements:
that the switch operates properly through a series of programmed sensing and timing functions.
1. Main contacts to connect and disconnect the load to
and from the source of power
A standard IQ Transfer will:
• Monitor Normal and Emergency source voltages and
frequencies
• Provide undervoltage monitoring of Normal and
Emergency sources
• Permit customer programming
• Display real time and historical information
• Permit system testing
• Offer Help Screen assistance
• Store customer/factory established parameters in nonvolatile memory
• Communicate using a PONI
• Provide faceplate source/load status indications
2. A transfer mechanism to affect the transfer of the
main contacts from source to source
3. Intelligence/supervisory circuits to constantly monitor
the condition of the power sources and thus provide
the intelligence necessary for the switch and related
circuit operation
This manual deals with the third basic element of the
automatic transfer switch, the required intelligence/ supervisory circuits. Prior to the introduction of IQ Transfer, this
function was performed by a door mounted logic panel.
The logic panel could be the relay logic type or the solid
state logic type. In either case, the panel consisted of a
number of individually mounted and wired devices offering a limited amount of system flexibility, especially in the
case of the relay logic design. IQ Transfer brings intelligence, supervisory and programming capabilities, never
before available, to automatic transfer switch equipment.
A wide array of additional features are available to
address the most sophisticated system requirements,
such as:
• Previously unavailable Load Monitoring and Delayed
Transition
• In-phase Transition
1.3 PRODUCT OVERVIEW
1.4 FUNCTIONS/FEATURES/OPTIONS
The IQ Transfer is a comprehensive, multi-function,
micro-processor based automatic transfer switch controller. It is a compact, self-contained, panel mounted
device designed to replace traditional relay and solid
state logic panels (Figures 2-1 and 2-2).
The primary function of IQ Transfer is to accurately monitor power sources and provide the necessary intelligence
to operate a transfer switch in an appropriate and timely
manner. In addition, IQ Transfer provides useful present
and historical data, reliable two-way communications,
and programming through the device’s faceplate or communications option. IQ Transfer features the proprietary
Sure Chip microprocessor technology to provide and
maintain superior precision and versatility during both
programming and data access.
Designed to meet the needs of markets worldwide, IQ
Transfer:
• Is a UL Recognized Component
• Meets Seismic Requirements of Uniform and
California Building Codes (exceeding requirements of
worst case Zone 4 levels)
• Meets Intent of UL 991
• Meets IEC 801-2, 3, 4 and 5
• Meets CISPR 11
• Complies with FCC Part 15, Subpart B, Class A
IQ Transfer provides an unmatched degree of programmed flexibility to address the needs of any system.
It operates from most system voltages available worldwide at 50 or 60 Hertz. In addition, a period of no control
power operation is provided. IQ Transfer monitors the
condition of the 3-phase line-to-line voltage and frequency of both the Normal and Emergency sources. It can
also be programmed for single phase operation. IQ
Transfer provides the necessary intelligence to insure
1.4.1 OPERATIONAL SIMPLICITY
From installation to programming to usage, IQ Transfer
was designed with operational simplicity in mind. Only
one style needs to be considered, regardless of
input/output requirements or system voltages and frequencies. IQ Transfer provides the functionality of
numerous other devices combined in one package that
mounts in less than 7 by 11 inches of panel space.
The user friendly front panel interface simplifies routine
operation, programming, data presentation and setting
adjustments. An LED based display provides the flexibility
of large character displays for enhanced visibility. The
operation of front panel membrane pushbuttons moves
Effective 6/00
I.B. ATS-I005
Page 3
the IQ Transfer display from function to function or step to
step within a function. Three LEDs at the top of the faceplate provide an immediate indication as to the device’s
operational mode. An integral Help Mode provides immediate user assistance in the form of English language
message displays through the use of a front panel Help
pushbutton.
With a Product Operated Network Interface (PONI), the
IQ Transfer is communications ready and compatible
with other devices in the IQ Family of products. The
Communication Module (PONI) is available in three versions, the INCOM PONI, RS-232 PONI and PONI
Modem. Reliable two-way communications can be provided over a twisted pair communications network. With
the INCOM PONI, IQ Transfer is compatible with the
Cutler-Hammer IMPACC system.
1.4.2 STANDARD AND OPTIONAL FEATURES
A variety of programmable features are available to
meet a wide variety of application requirements.
Individual features or feature combinations provide the
intelligence required to tailor switches to individual
needs.
The features are factory activated, depending upon customer requirements. The specific variable setpoints
associated with standard and factory activated features
are stored in a nonvolatile memory. Activated feature
setpoints are available for customer adjustment. Any
feature not selected and factory activated cannot be
viewed or adjusted.
NOTICE
With respect to their use in this document and as
they relate to automatic transfer switch operation,
the following words or phrases are defined:
Available
A source is defined as available when it is within its
undervoltage/overvoltage/underfrequency/overfrequency (if applicable) setpoint ranges for the nominal voltage
and frequency setting.
Fails
A source is defined as failed when it is outside of its
undervoltage/overvoltage/underfrequency/overfrequency (if applicable) setpoint ranges for the nominal voltage
and frequency setting.
Effective 6/00
Normal Source
The Normal Source is defined as the source that is preferred. The Preferred Source setting allows the operator
to select Source 1, Source 2 or NONE as the Preferred
Source. If NONE is chosen, the Preferred Source or the
Normal Source will be the source that is presently
attached to the load. If the Preferred Source feature is
not available from the factory, the default is set as being
Source 1 as the Preferred and Normal Source.
Emergency Source
The Emergency Source is defined as the source that is
not preferred. If NONE is chosen for the Preferred
Source setting, the Emergency Source will be the
source that is presently not attached to the load.
Therefore, in this condition after a transfer, what was the
Normal and Emergency Sources will switch between
Source 1 and 2. If the Preferred Source feature is not
available from the factory, the default is set with Source
2 as the Emergency Source.
Option #
For personnel who are familiar with previous transfer
switch controller option specifications, an attempt at
equivalence to some of the features is made.
IQ Transfer features with a brief description follow. The
actual programmable setpoints for each feature are covered in Section 5.
Standard Feature: Time Delay on Engine Start
(TDES)
TDES is used where the source is an engine generator.
It delays initiation of the engine start circuit in order to
override momentary power outages and/or fluctuations.
This timer and the associated engine start circuit will
operate with or without control power. There are two
separate start circuits, one for each source when applications of two generators are selected, although the
same TDES timer value is used for both. When one
generator is selected, this timer’s engine start circuit will
operate on generator 2 for source 2. If the source that is
being transferred to has a generator and that source is
already available, the TDES timer is bypassed.
Standard Feature: Time Delay Normal to
Emergency (TDNE)
TDNE delays the transfer to the Emergency Source to
permit stabilization of the Emergency power source
before the transfer is made. This timer will begin the
countdown from its setting value when the Emergency
Source becomes available. If the Normal Source should
become available during the countdown of this timer,
the timer will be aborted.
I.B. ATS-I005
Page 4
Standard Feature: Time Delay Emergency to
Normal (TDEN)
TDEN delays the transfer to the Normal Source to permit stabilization of the Normal power source before the
transfer is made. This timer will begin the countdown
from its setting value when the Normal Source becomes
available. During the countdown of this timer, if the
Normal Source should become unavailable, the timer
will be aborted. If the Preferred Source is available and
the Emergency Source fails while the TDEN timer is
counting down, the TDEN timer will be bypassed.
Standard Feature: Time Delay for Engine Cool-Off
(TDEC)
TDEC permits the generator to run under a no-load condition after a transfer from the generator source has
been made. Countdown timing begins when the transfer
is completed. In applications where two generators are
selected, the same cool-off timer setting value is used
for both.
Standard Feature: Time Delay Emergency Failure
(TDEF)
TDEF is used where at least one source is an engine
generator. TDEF will delay an available source from
being declared unavailable in order to override momentary generator fluctuations. This time delay is only implemented when the load is connected to a generator
source. TDEF is not displayed when the number of generators is zero.
!
CAUTION
CHANGING THE SYSTEM NOMINAL VOLTAGE OR
FREQUENCY SETPOINTS WILL CAUSE PICKUP
AND DROPOUT SETPOINTS TO CHANGE AUTOMATICALLY TO NEW DEFAULT VALUES.
Standard Feature : System Nominal Frequency
(NOMF)
There are only two choices for system nominal frequency of the distribution system, 50 or 60 Hertz. The
dropout/pickup, underfrequency and overfrequency
upper and lower setting limits are based on the nominal
frequency value.
Standard Feature: System Nominal Voltage (NOMV)
This refers to the standard system nominal RMS line to
line voltage. A wide range (120 to 600) of sensing voltage is available to be programmed. The dropout/pickup,
undervoltage and overvoltage upper and lower setting
limits are based upon the nominal voltage value.
Standard Feature: Undervoltage Monitoring for
Source 1 (1UVD, 1UVP)
This feature constantly monitors Source 1 for an undervoltage condition. When the Source 1 voltage drops to a
value equal to or below the undervoltage dropout setting, the source will become unavailable. The source’s
voltage will then have to rise to a value that is equal to
or above the pickup setting to become available again.
Standard Feature: Undervoltage Monitoring for
Source 2 (2UVD, 2UVP)
This feature functions the same as Standard Feature
(1UVD, 1UVP), except for Source 2 instead of Source 1.
Standard Feature: Underfrequency Monitoring for
Source 2 (2UFD, 2UFP)
This feature functions the same as Optional Feature
26E, except for Source 2 instead of Source 1.
Standard Feature: Commit to Transfer During TDNE
Timing (CTDNE)
This feature provides for selection as to whether or not
commitment to transfer is desired when Time Delay
Normal to Emergency countdown has begun. If no
commitment is chosen and the Normal Source returns
to availability when the TDNE timer is counting down,
the transfer is aborted and the engine generator (if
applicable) is cooled down.
Standard Feature: Engine Test Mode (TMODE)
This feature provides selection of the type of test that
can be initiated by the front panel Engine Test pushbutton. An engine test without transferring the load to it, or
an engine test with a full transfer of the load to the
engine can be chosen. Load testing is fail-safe. If the
generator fails during testing for any reason, the IQ
Transfer will signal the transfer switch to return to normal. If disable test mode is chosen, the front panel
pushbutton cannot be used to initiate a test.
Standard Feature: Test Engine Run (TER)
This feature provides selection of the length of time in
hours and minutes that the IQ Transfer will enable the
generator contacts during an Engine Test that was initiated from the front panel pushbutton or for the plant
exerciser feature, if applicable.
Optional Feature 5C: Overfrequency Monitoring for
Source 2 (2OFD, 2OFP)
This feature functions the same as Optional Feature
26F, except for Source 2 instead of Source 1.
Effective 6/00
I.B. ATS-I005
Optional Feature 5E: Overvoltage Monitoring for
Source 2 (2OVD, 2OVP)
This feature function the same as Optional Feature 26C,
except for Source 2 instead of Source 1.
Optional Feature 8C/8D: Transfer Time Delay
Bypass
This factory programmed feature allows an external
pushbutton input to be used to bypass the timer for
Standard Feature (TDNE) or Standard Feature (TDEN)
individually, or both simultaneously. This feature is usually used in testing when it is not desirable to wait for
completion of the timing sequence.
Optional Feature 9B: Maintenance Selector
Switch (MSS)
Marked “OFF”, “ON”. This feature provides selector
switch disconnection of control to the transfer motor
thus allowing testing of the transfer switch control logic
circuitry without initiating load transfer. Manual disconnection is standard on all Cutler-Hammer transfer
switches. Positioning the MSS in the “OFF” position isolates the control circuit from the transfer motor, permitting manual operation of the transfer switch or testing of
logic circuitry without load transfer.
Optional Feature 10: Preferred Source Selection
(PRF SRC)
This feature permits the selection of either source (1 or
2) as the Preferred or Normal Source. The Normal
Source is the source that the switch always looks to for
availability so that it can transfer to it. When two generators are selected and the switch has transferred to the
Emergency Source, the IQ Transfer will constantly be
waiting and attempting to start the generator on the
Preferred Source so that it may return to it. IF NONE is
chosen, the Preferred Source or the Normal Source will
be the source that is presently attached to the load.
Optional Feature 16: Overcurrent Protection
When integral overcurrent protection is provided for
either one or both sources, the need for separate
upstream overcurrent protection, in most instances, is
eliminated. With this factory installed feature in the IQ
Transfer, further automatic transfer operation is lockedout until the appropriate source breaker is reset.
Optional Feature 23: Plant Exerciser (EXER)
This feature provides for the automatic test operation of
the generator for a pre-selected weekly interval. When
the test is running, pressing and releasing the Engine
Test pushbutton will cancel the test. The day of the
week, hour, and minute that exercising is desired can be
Effective 6/00
Page 5
programmed into the IQ Transfer. The type of test,
whether a load transfer or just an engine test, can also
be selected. Load testing is fail-safe. If the generator
fails during testing for any reason, the IQ Transfer will
signal the transfer switch to return to normal.
Optional Feature 26C: Overvoltage Monitoring for
Source 1 (1OVD, 1OVP)
This feature constantly monitors Source 1 for an overvoltage condition. When the Source 1 voltage rises to a
value equal to or above the overvoltage dropout setting,
the source will become unavailable. The source’s voltage will then have to drop to a value that is equal to or
below the pickup setting to become available again.
Optional Feature 26D: Go To Emergency
This feature enables an external contact closure to initiate a transfer from the Normal Source to the Emergency
Source. If the external contact is closed and the
Emergency Source fails, the IQ Transfer will transfer the
load back to the Normal Source.
Optional Feature 26E: Underfrequency Monitoring
for Source 1 (1UFD, 1UFP)
This feature constantly monitors Source 1 for an underfrequency condition. When the Source 1 frequency
drops to a value equal to or below the underfrequency
dropout setting, the source will become unavailable. The
source’s frequency will then have to rise to a value that
is equal to or above the pickup setting to become available again.
Optional Feature 26F: Overfrequency Monitoring for
Source 1 (1OFD, 1OFP)
This feature constantly monitors Source 1 for an overfrequency condition. When the Source 1 frequency rises
to a value equal to or above the overfrequency dropout
setting, the source will become unavailable. The
source’s frequency will then have to drop to a value that
is equal to or below the pickup setting to become available again.
Optional Feature 29G: Type of Operation (Selectable
Automatic or Manual)
This feature provides a two position selector switch
marked Auto/Manual which permits the selection of
automatic or manual operation. It includes devices for
manual operation when the selector switch is in the
manual position.
Optional Feature 29J: Type of Operation (MANTR)
This feature provides for a selection between an automatic transfer and re-transfer mode or a manual push-
Page 6
button re-transfer to Normal from the Emergency
Source mode. If this option is not selected the factory
default selection is automatic.
Optional Feature 32A: Time Delay Neutral (TDN)
This feature provides a time delay in the transfer switch
Neutral position when both breakers are open. This
delay takes place when the load is transferred in either
direction to prevent excessive in-rush currents due to
out-of-phase switching of large motor loads. This feature
is not available with the Neutral Load Sense Delay
(TDNLD) feature.
Optional Feature 32B: Load Voltage Decay (LDCY)
This feature utilizes the load voltage measurements to
sense back EMF that is generated when the transfer
switch is in the Neutral position. It provides a delay in
transfer in either direction if an unacceptable level is
sensed as established by a customer programmed
level. The transfer will not take place until the back EMF
decays below the acceptable programmed level. This
feature has a separate setting of enabling or disabling
the operation. If disabled, the transfer switch will not
delay in the Neutral position and will transfer between
the sources as fast as possible. This feature is not available with the Time Delay Neutral (TDN) Feature 15.
Optional Feature 32C: In-Phase/Load Voltage Decay
In-phase transition is a feature that will allow a transfer
between two live sources only when the phase difference between the two sources is near zero. This is an
open transition transfer that prevents in-rush currents
from exceeding normal starting currents in the case
where motor loads are being transferred.
Load Voltage Decay utilizes the load voltage measurements to sense back EMF that is generated when the
transfer switch is in the Neutral position. It provides a
delay in transfer in either direction if an unacceptable level
is sensed as established by a customer programmed
level. The transfer will not take place until the back EMF
decays below the acceptable programmed level. This feature has a separate setting of enabling or disabling the
operation. If disabled, the transfer switch will not delay in
the Neutral position and will transfer between the sources
as fast as possible. This feature is not available with the
Time Delay Neutral (TDN) Feature 15.
Optional Feature 32D: In-Phase/Time Delay Neutral
In-phase transition is a feature that will allow a transfer
between two live sources only when the phase difference between the two sources is near zero. This is an
open transition transfer that prevents in-rush currents
from exceeding normal starting currents in the case
where motor loads are being transferred.
I.B. ATS-I005
Time Delay Neutral provides a time delay in the transfer
switch Neutral position when both breakers are open.
This delay takes place when the load is transferred in
either direction to prevent excessive in-rush currents
due to out-of-phase switching of large motor loads. This
feature is not available with the Neutral Load Sense
Delay (TDNLD) feature.
Optional Feature 35: Pre-Transfer Signal (TPRE)
Typically associated with elevator controls, this feature
provides for the control of an addressable relay to
remotely signal an elevator that a re-transfer is about to
take place. A permissive report-back signal from the elevator, telling the IQ Transfer that the elevator has
reached the floor and opened its doors, is also recognized to facilitate faster transfer operation. Should the
permissive signal not be used or does not occur, the IQ
Transfer has a programmed overriding pre-transfer
delay timer that can be set from 0 to 2 minutes.
Optional Feature 36: Load Shed From Emergency
This feature enables an external contact to initiate a
transfer when the load is connected to Source 2. If the
contact is opened when Source 1 is not available the IQ
Transfer will go to the neutral position with both sources
disconnected from the load. If the contact is opened
when Source 1 is available, the IQ Transfer will transfer
the load from Source 2 to Source 1.
Optional Feature 37: Service Equipment
This factory programmed feature makes the transfer
switch suitable for a service equipment rating by
responding to a Go-To-Neutral input.
Optional Feature 45: Load Sequencing Capability
(TSEQ)
This feature provides the sequential closure of up to 10
remote relays after a transfer. A customer programmed
time delay is available to delay closure between each of
the relays.
Optional Feature 46: Potential Transformer (PT)
Ratio
This feature allows external voltage transformers to be
used on the IQ Transfer’s source and load sense inputs.
Once this option is enabled, the PT Ratio setpoint can
be adjusted in steps of 1, between 2:1 and 500:1. Also
when this option is enabled the Nominal System Voltage
setting will be fixed at 120 or 110 volts, depending upon
the Nominal System Frequency setting. If the Nominal
System Frequency setting is 60Hz then the Nominal
System Voltage will be fixed at 120 volts and all voltage
pick-up and drop-out setpoints will be based upon the
120 volt level. The same is true of a Nominal System

SECTION 2: HARDWARE DESCRIPTION
2.1 GENERAL
The purpose of this section is to familiarize the reader
with IQ Transfer hardware, its nomenclature, and to list
the unit’s specifications. The information presented is
divided into the following four parts:
• Operator Panel
• Rear Access Area
• External Hardware
• Specification Summary
2.2 OPERATOR PANEL
The operator panel, which is normally accessible from
the outside of a panel or door, provides a means for:
• Being alerted to specific conditions
• Receiving functional help
• Programming
• Parameter Monitoring/Selection/Metering
LEDs, a display window, pushbuttons, and a mimic bus
make up the front accessible operator panel (Figure
2-1).
Seventeen individual LEDs are lit when performing or
indicating a specific function. For detailed information on
individual LEDs refer to Paragraph 3.2.
The LED type display window is used to display all IQ
Transfer monitored parameters, setpoints and messages
in easy to read formats. The alpha numeric display is
approximately 0.75 by 4.25 inches and is able to display
up to eight characters at a time. For details concerning
the kind of information that can be viewed in the display
window refer to Paragraph 3.3.
The front operator panel supports six long-life membrane pushbuttons. Pushbuttons accomplish their function when pressed and released. Refer to Paragraph 3.4
for information concerning the function of specific pushbuttons.
2.3 REAR ACCESS AREA
The rear access area of the IQ Transfer is normally
accessible from the rear of an open panel door
(Figure 2-2).
All wiring connections to the IQ Transfer are made at the
rear of the chassis. For the sake of uniform identification,
the frame of reference when discussing the rear access
Effective 6/00
Page 7
area is facing the back of the IQ Transfer with the panel
door open. The communication module port, for example, is located on the upper right rear of the unit. The
Run/Program Switch, used to determine the IQ Transfer
Mode, is located in the lower right near the control power
inputs. Detailed information relative to any connection
made to the rear access area is presented in Section 4
entitled “Operation.”
2.3.1 LEFT REAR OF CHASSIS
The left rear of the chassis provides self locking female
connectors J1, J2 and J3 for voltage monitoring of
Source 1 (S1), Source 2 (S2) and the Load respectively.
Terminal block J4 provides DC wetted connections for
various functional inputs. See Paragraph 4.3 for more
information on input functionality.
2.3.2 RIGHT REAR OF CHASSIS
The right rear of the chassis provides a port that will
accept the D-sub male connector of the optional
Communication Module (PONI). A self locking female
connector J7 is provided for Sources 1 and 2 control
power input.
Customer programming is provided through the
Program/Run Toggle Switch. While the switch is in the
Program position, the IQ Transfer continues to operate
in keeping with previously programmed setpoints.
Terminal block J5 provides dry relay contacts for primary control outputs. Physically these relays are comprised
of two latching Form A relays for generator start contacts, and seven conventional coil Form C relays necessary to complete the electrical control function.
2.4 EXTERNAL HARDWARE (COMMUNICATION
MODULE)
External hardware is viewed as any optional device
mounted directly to or remotely from the IQ Transfer,
such as a communication module. Communications is
made possible by mounting a small, addressable communication module (PONI) to the back of the IQ
Transfer (Figure 2-3) or in a remote location. Since the
IQ Transfer is always supplied with a communications
port, a PONI can be easily retrofitted to the IQ Transfer
at any time. It is recommended that the control
power to the IQ Transfer be removed prior to connecting or disconnecting a PONI. When using the
INCOM PONI on the IQ Transfer, the PONI function
switches should be set to either of the Standard PONI

SECTION 3: OPERATOR PANEL
3.1 GENERAL
The operator panel, which is normally accessible from
the outside of a panel or door, provides a means for
being alerted to specific conditions, receiving functional
help, programming, and parameter monitoring/selection
(Figure 2-1). For the purpose of familiarization, the
panel is divided into three sub-sections and discussed
individually:
• LEDs
• Pushbuttons
• Display Window
NOTICE
With respect to their use in this document and as
they relate to automatic transfer switch operation,
the words “Cycle” and “Event” are defined as follows:
Cycle –A complete operation from Normal to
Emergency to Normal.
Event –A failure resulting in some type of switch
and/or switch intelligence action.

Refer to Appendix D for an overall view of IQ
Transfer operations in the form of a Menu Tree.
3.2 LEDS
LEDs are used to indicate the device’s mode of operation,
the status of the system, and the operations and/or conditions of displayed functions. Three LEDs at the top of the
IQ Transfer provide a quick snapshot of the unit’s status
(Mode). Seven LEDs, just above the display window, indicate which portions of the mimic bus are active, and the
actual status of both sources and load. The remaining
seven LEDs, just below the display window, are lit to indicate the identity of information being displayed.
Automatic Mode LED
This LED blinks green indicating that the IQ Transfer is
operating and providing the transfer switch control function in keeping with programmed setpoints. If the LED is
not lit or is on continuously, a problem may be indicated.
Effective 6/00
Test Mode LED
This LED is lit red upon entering the Test Mode. The
Test Mode can only be entered with the LEDs below the
display window not lit. When a test is initiated, the
Status LED lights. Both LEDs will turn off upon the successful completion of a test cycle.
Program Mode LED
This LED is lit red when the Run/Program switch on the
rear of the chassis is in the Program position. This condition permits programming of control setpoints. When

source LED will also be lit.
3.3 PUSHBUTTONS
The front operations panel supports six blue membrane
pushbuttons. Pushbuttons accomplish their function
when pressed and released. Certain pushbuttons, like
the Increase and Decrease Pushbuttons, will also continue to scroll if they are pressed and not released. The
Run/Program Switch, located on the right rear chassis,
is not a membrane pushbutton. It will, however, be
addressed in this section since it is required to move
between the Run and Program Modes.
3.3.1 RUN/PROGRAM TOGGLE SWITCH
The right rear mounted Run/Program Toggle Switch
establishes whether the IQ Transfer is in the Run Mode
or the Program Mode. Normally the switch is set in the
Run position to permit normal programmed operations.
Programmed setpoints can only be altered with the
switch in the Program position. Altered setpoints are
stored and establish the new operating conditions of the
IQ Transfer only after the switch is moved back to the
Run position.
3.3.2 HELP PUSHBUTTON
When the Help Pushbutton is pressed and released with
the IQ Transfer in any mode, an English language message will scroll across the display. Pushing and releasing the pushbutton a second time will abort the message. Messages and explanations relative to what is
being viewed in the display are intended to prompt and
assist the operator.
NOTICE
Pressing and Releasing the Help Pushbutton with
the IQ Transfer display window blank causes all of
the front panel LEDs to momentarily light before
scrolling a message across the display (Figure 3-1).
The message indicates the software version, revision number, and an encoded catalog number that
reveals to Cutler-Hammer what specific options are
included with this particular unit. The customer may
be asked for this information by Cutler-Hammer during a troubleshooting or return process.
3.3.3 ENGINE TEST PUSHBUTTON
When the Engine Test Pushbutton is pressed and
released twice with the IQ Transfer in the status state, a
self-test is initiated. This test can be initiated and
accomplished while in the Run or Program Modes.
Pressing the Engine Test Pushbutton again while in the
engine run condition aborts the test.
Effective 6/00
I.B. ATS-I005
Page 13
Upon test initiation, a generator start of the non-preferred
source is engaged after TDES timeout. If a full test is programmed, a transfer with all programmed timers occurs.
The test engine run timer will hold the load for the required
timeout and the test is concluded with a re-transfer cycle.
For an engine run only test, no transfer will occur and the
engine will run for the programmed run time.
NOTICE
The optional Plant Exerciser Feature allows for
automatic programming of the desired test cycle on
a weekly basis. If the switch is unable to process
either a Plant Exerciser request or the Engine Test
Pushbutton itself due to transfer switch status, the
request is ignored.
3.3.6 INCREASE AND DECREASE PUSHBUTTONS
These pushbuttons, when pressed and released for step
by step changes or held depressed for scrolling, increase
or decrease setpoints while in the Programming Mode or
make Time/Date changes. While historical information is
being displayed, the Increase Pushbutton will scroll
through events, and the Decrease Pushbutton will scroll
through the actual time and date of the event. In addition,
if both buttons are pressed and released simultaneously
while viewing any of the historical logged values, the value
resets to zero. Refer to paragraph 3.4.4 and Appendix B
for additional information pertaining to accessing historical
information and historical data definitions. Simultaneously
pressing and releasing the Increase and Decrease
Pushbuttons will also reset an alarm condition.
3.4 DISPLAY WINDOW
3.3.4 DISPLAY SELECT PUSHBUTTON
As the Display Select Pushbutton is pressed and
released, IQ Transfer steps through the following display categories:
• Status
• Source 1
• Source 2
• Load
• History
• Time
• Date
• Setpoints
3.3.5 STEP PUSHBUTTON
The Step Pushbutton steps through the different available information within the display category selected as
the pushbutton is pressed and released.
When Source 1 is the category displayed for example,
use of the Step Pushbutton will step the display through
the voltages, frequency and status condition associated
with Source 1. In the Time/Date category, however, this
pushbutton has an additional purpose. The Step
Pushbutton is also used to permit programming of the
time and date by stepping through the different time and
date categories (Hours, Minutes, Month, Day and Year).
The actual time or date category is moved up or down
using the Decrease or Increase Pushbuttons described
next.
The IQ Transfer provides a comprehensive array of monitored parameters, setpoints and messages via its easy
to read Display Window. Up to eight large characters are
used to convey a wealth of information. Eight different
displays can be presented via the Display Window:
• Status Display
• Source 1 Display
• Source 2 Display
• Load Display
• History Display
• Time/Date Display
• Setpoints Display
• Help Display
NOTICE
Although a wide variety of parameters and setpoints
can be displayed, they are not displayed if they were

SECTION 4: OPERATION
4.1 GENERAL
This section specifically describes the operation and
functional use of the IQ Transfer. It is divided into three
main categories:
• Automatic Mode
• Test Mode
• Programming Mode
The practical use of and operation within each specific
category will be discussed. In this section it is assumed
that prior sections were reviewed and that the operator
has a basic understanding of the hardware. It is important that the operator have a good grasp of the functional use of the operator panel as covered in Section 3.
This will make movement within each category and
between categories a simple task. This familiarity will
quickly put the unsurpassed capabilities of IQ Transfer
at the operator’s fingertips.
NOTICE
It is important to remember that IQ Transfer continues to provide programmed protection and automatic operation no matter which mode the device is in
at the time it is called upon to operate.
NOTICE
Refer to Appendix D for an overall view of IQ
Transfer operations in the form of a Menu Tree.
4.2 AUTOMATIC MODE
The Automatic Mode of IQ Transfer provides for automatic transfer and re-transfer from source to source as
dictated by the features supplied and their programmed
setpoint values. It provides a summary of IQ Transfer’s
intelligence and supervisory circuits which constantly
monitor the condition of both normal and emergency
power sources thus providing the required intelligence
for transfer operations. These circuits, for example,
automatically initiate an immediate transfer of power
when power fails or voltage levels drop below a preset
value. Exactly what IQ Transfer will initiate in response
to a given system condition depends upon the combination of standard and selected optional features. Refer to
Paragraphs 1.3 and 1.4 for IQ Transfer’s standard and
optional features.
When the preferred source is connected and the automatic transfer switch is operating normally, the
Automatic LED blinks green and no message appears in
the display window. In the event of a power failure, the
display automatically becomes active showing the status of timers relative to an alternate source transfer.
Once the alternate source becomes available, the transfer is made consistent with pre-programmed features. In
a similar manner, transfer back to the preferred source
is made once the preferred source is again available.
System conditions relative to the sources and the load
are clearly indicated by the LED type mimic bus.
4.3 CONTACT INPUTS
As described in Section 2, the rear access area provides for access to all input connections. Each contact
input provides 50 volts at 10ma. Refer to Figure 2-3 for
a graphical representation and position of all input connections.
NOTICE
Certain inputs may not be operational depending on
user purchased options.
IQ Transfer provides for eight individual contact input
control signals on terminal block J4. as follows:
Source 1 Auxiliary Close
This input is located on Pins 1 and 2 of Connector J4
and wired to the Source 1 breaker auxiliary contact that
is closed when the Source 1 breaker is closed.
Source 2 Auxiliary Close
This input is located on Pins 3 and 4 of Connector J4
and wired to the Source 2 breaker auxiliary contact that
is closed when the Source 2 breaker is closed.
Lockout
This input is located on Pins 5 and 6 of Connector J4.
The contact is closed to indicate that both the Source 1
and Source 2 breakers are available. Opening of this
contact signifies a tripped circuit breaker or circuit
breaker non-availability which will cause IQ Transfer to
inhibit further operation.
Go To Emergency
This input is located on Pins 7 and 8 of Connector J4
and is enabled with the Area Protection option. When
the external contact is closed, a transfer to the
Emergency Source will be initiated. If the Emergency
Effective 6/00
I.B. ATS-I005
Source should fail and the Normal Source is available,
the IQ Transfer will initiate a transfer to the Normal
Source.
Bypass Timers
A momentary closure on Pins 9 and 10 of Connector J4
will bypass the timer for TDNE and/or TDEN.
Go To Neutral
A maintained closed contact on Pins 11 and 12 of
Connector J4 forces the controller to switch to the neutral position, thereby disconnecting the load from both
sources.
Manual Re-Transfer
With manual operation set, momentary closure on Pins
13 and 14 of Connector J4 allows IQ Transfer to proceed with a re-transfer operation at the operators discretion. Should a failure of the emergency source occur
while waiting for the manual return, the re-transfer proceeds automatically.
Emergency Inhibit
This input is located on Pins 15 and 16 of Connector J4
and is enabled with the Load Shed From Emergency
option. If the contact is opened and the load is connected to Source 1, no action will be taken. If the contact is
opened when Source 1 is not available, and the load is
connected to Source 2, the IQ Transfer will go to the
neutral position with both sources disconnected from the
load. If the contact is opened when Source 1 is available, and load is connected to Source 2, the IQ Transfer
will do a complete transfer from Source 2 to 1.
INCOM Sub-Network
Pins 17, 18 and 19 of Connector J4 provide for the
INCOM (Industrial Communications) interface. Refer to
Communications Mode in this section for more information.
4.4 INCOM SUB-NETWORK
Pins 17, 18 and 19 of connector J4 provide for the
INCOM (Industrial Communications) sub-network interface. From the IQ Transfer a single twisted pair of wires
can remotely communicate with devices up to 7500 feet
away. Using the same technology and protocol as our
IMPACC communications network this system will allow
the IQ Transfer to be a master to Addressable Relay IIs
that accomplish the Pre-transfer and Load Sequencing
features. The sub-network can be enabled for either or
both of these features. The Addressable Relay IIs are a
product that is part of the IMPACC family of communi-
Effective 6/00
Page 17
cating products. The addressable Relay II is a form C
relay that includes 2 status inputs, a LED to show the
status of the relay and a LED to show the communications transmit status. Figure 4-1 shows a typical configuration that has both the Pre-transfer and Load
Sequencing features enabled.
4.4.1 PRE-TRANSFER SUB-NETWORK
The Pre-transfer signal as previously described allows for
loads, typically an elevator, to communicate with the IQ
Transfer. The important design features of this configuration are that the relay can be located up to a mile away
and it reports back its status and the state of input IN1.
The Addressable Relay II must be set for:
• 1200 BAUD rate
• WATCHDOG feature disabled
• RELAY PULSE feature disabled
• Address set for 001
• Reportback input IN1
The IN1 connections of the relay are the reportback
input to the IQ Transfer and should be connected to a
contact output from the elevator controller. Refer to the
Addressable Relay II and the elevator controller manufacturer’s instruction literature for proper control power
and input signal voltage levels. When proper operating
voltage is present between the IN1 input pins, a positive
status will be reported back to the IQ Transfer. During
normal operation the relay’s contact will be de-energized. When a transfer is pending and after the TDNE
(or TDEN) timer has counted down (if enabled), the IQ
Transfer will send a communications close command to
the relay. Once the relay has closed, the IQ Transfer will
start the Time Delay Pre-transfer count down timer to
delay the transfer operation until the counter has finished. After the timer has started, the IQ Transfer will
continuously poll the relay for the status of its input circuit. If the relay returns a positive status of IN1, the IQ
Transfer will assume that the elevator has arrived at the
proper floor and opened the doors. The IQ Transfer will
then abort the remaining Time Delay Pre-transfer timer
and continue with the transfer operation. Once the
transfer is complete, the IQ Transfer will return to the
relay and send a communication open command.
This option is only functional if closed and In-phase
modes are disabled. The Pre-transfer sequence only
occurs if both sources are available. If only one source
is available, the Pre-transfer sequence is bypassed.

Figure 4-1 Typical Wiring of Addressable Relays to the IQ Transfer
4.4.2 LOAD SEQUENCING SUB-NETWORK
The Load Sequencing signal allows loads to be activated in a sequence after a transfer has taken place.
Addressable Relay II’s are used to enable up to 10 separate loads.
The Addressable Relay II must be set for:
• 1200 BAUD rate
• WATCHDOG feature disabled
• RELAY PULSE feature disabled
• Address range from 002 to 00B
Immediately before the transfer switch has moved from
the neutral position to the new source, all 10 of the
sequence relays are sent open commands. The IQ
Transfer will make several attempts to communicate
with a relay. If an address or relay is not used or if a
relay fails to respond, the IQ Transfer will move on to
the next relay. Once the attempt to turn all the relays off
has been made, the IQ Transfer will start to sequence
the 10 relays on. Starting with address 002, the IQ
Transfer will send the relay the command to close. After
this relay responds, the IQ Transfer will start the Time
Delay Sequence timer (TSEQ). When this timer has
counted down to zero, the IQ Transfer will increment to
the next address of 003 and send it the close command.
Should there be no relay, the IQ Transfer will display the
NO R xx (where xx is the address) message on the front
panel, abort the time delay and then step to the next
address. This will continue until a relay that responds is
reached or after address 00B, which is the last address,
is tested.

4.5 RELAY OUTPUTS
As described in Section 2, the rear access area provides for access to all output connections. Refer to
Figure 2-3 for a graphical representation and position of
all output connections. The relay functions are divided
into two categories:
• Customer Connections
• Transfer Operation Contacts

This Form C relay is used to indicate the availability of
Source 1. The full Form C contact of this relay is implemented with Common Pin 14, Normally Closed Pin 13,
and Normally Open Pin 12 of Connector J5. This relay
essentially duplicates the Source 1 available status LED
meaning that the setpoint criteria has been met.
4.5.2 TRANSFER OPERATION CONTACTS

Alarm
This Form C relay is used to indicate an alarm condition.
The full Form C contact of this relay is implemented with
Common Pin 8, Normally Closed Pin 7, and Normally
Open Pin 6 of Connector J5. The relay is normally deenergized to indicate the absence of an alarm state.
Energization of the relay indicates the presence of an
alarm condition. Alarm conditions include improper
circuit breaker operation, motor operator failure, and
unsuccessful in-phase transition. An alarm may be reset
by simultaneously pressing the Increase and Decrease
Pushbuttons.

4.7 PROGRAMMING MODE
IQ Transfer is fully programmable from the device’s
faceplate once the Run/Program switch on the rear of
Effective 6/00
The Test Mode is intended to permit the periodic performance of tests of the system. To enter the Test Mode,
the display window must be blank.
When the Engine Test Pushbutton is pressed and
released, “START” will be shown in the display window
and the Status LED will be lit. At this point, if the initiation of a test is not desired, pressing the Increase and
Decrease Pushbuttons simultaneously will clear the display window. In addition, if any of the display pushbuttons are not touched for 2 1/2 minutes, the Test Mode
and Display Window would be cleared. If a test is
desired, the Engine Test Pushbutton must be pressed a
second time before the 2 1/2 minutes have expired. At
this time the Status and Test Mode LEDs are lit red, and
one Test Mode cycle is implemented.
The exact test conditions are determined by programmed setpoints. Whether or not to transfer the load
during testing, disable the engine test completely, and
the engine test run time are operator selected parameters. Refer to Section 5 Programming and specifically
Table 5.1 for test programming details.
A load transfer test cycle includes a full generator start,
a transfer, and a re-transfer. For the test cycle to proceed, the Normal Source must be available. The test
cycle will be aborted if the Emergency Source does not
become available within a set time-out period, or if a
needed source becomes unavailable. In addition, the
test will be aborted if the Test Pushbutton is again
pressed and released. Both LEDs turn off upon the successful completion of a test cycle, once the time delay
engine cool down timer has expired and the generator is
stopped.
If the “Number of Generators” setpoint is programmed
to zero, the Engine Test Pushbutton is not functional.
If the setpoint is programmed to two, the test will be performed on the generator not connected to the load.

the chassis has been moved to the Program position.
Any operator associated with programming the IQ
Transfer will quickly discover that IQ Transfer programming is just a matter of simple, repetitive steps. Because
of the importance placed, however, on this function and
its critical relationship to the systems proper functioning,
Section 5 is dedicated to the Programming Mode. Refer
to this section and Table 5.1 for details.
showing available and connected sources.
• Voltage and frequency measurements of Source 1
and Source 2. Voltage measurements of the Load.
• Display of all programmed setpoint values. These values may be changed and either saved to a file or
downloaded to the IQ Transfer over IMPACC.
4.8 COMMUNICATIONS
IQ Transfer is an IMPACC (Integrated Monitoring
Protection and Control Communications) compatible
device. As such, it can be remotely monitored, controlled and programmed when equipped with the communications option. The IQ Transfer is supplied with a
communications port as standard. This permits it to
have the communications option supplied from the factory or retrofitted at a later date. The communications
option is achieved by mounting a small, addressable
communications module, the PONI, to the back of the
IQ Transfer (Paragraph 2.4 and Figure 2-3).
IMPACC is a noise immune communications system
that permits communications from the IQ Transfer to a
master computer via a high frequency carrier signal over
a shielded twisted pair of conductors. The shielded
twisted pair of conductors can extend up to 7500 feet
without the use of repeaters. Communications between
IMPACC compatible devices, such as IQ Transfer and
the master computer is made possible by the INCOM
(Industrial Communications) chip, which accounts for
the system’s high degree of reliability.
4.8.1 IMPACC POWERNET SOFTWARE
PowerNet software provides the ability to monitor and
record power distribution system data as it is occurring.
PowerNet is a Microsoft Windows compatible application featuring user friendly, menu-driven screens with
easy set-up and operation. Additional features include:
• System/device alarm logging and reporting
• Time/event historical data logging
• Data trending
• Information storage/retrieval by device event
• Hardware diagnostics
• Dedicated computer not required
• Security password protection
• Gateway interface for connectivity to other information
networks
IMPACC PowerNet also provides the following features
unique to the IQ Transfer:
• Duplication of IQ Transfer front panel mimic bus
If the IQ Transfer Run/Program switch is in the
Program position, theNOTICE
setpoints cannot be downloaded over IMPACC.
• History information:
Source 1 Engine Run Time
Source 2 Engine Run Time
Source 1 Available Time
Source 2 Available Time
Source 1 Connected Time
Source 2 Connected Time
Load Energized Time
Number of Transfers
All history information is in hours and minutes. Each
individual value is resettable over IMPACC.
• Time-stamped history (time/date/reason) for all previous transfers.
• Capability to initiate an engine test.
• Updates the IQ Transfer real-time clock.
4.9 IN-PHASE TRANSITION
In-phase transition is an open transition with both
sources in-phase. The same anticipatory scheme used
for closed transition is also used for in-phase transition.
The advance angle is calculated based on the frequency difference between the two sources and also the
response time of the breaker. This results in the optimum reconnect angle of 0 degrees for all of the frequency difference values.
The criteria for in-phase transition are similar to closed
transition. Both sources must be available and the frequency difference must be less than the in-phase transition frequency difference setpoint (0.0 to 3.0 Hz). When
these conditions are met, the IQ Transfer will monitor
the phase difference between the two sources. The
synchronization timer will count down and be displayed
as “TSIP” while waiting for synchronization to be detected. When the phase difference is within the advance
angle window, the “transfer” command is given. This is
Effective 6/00
I.B. ATS-I005
an open transition but both sources will be in phase
when the transfer occurs.
If the synchronization does not occur within a specified
amount of time, the transfer will take place under
delayed transition and the alarm relay is energized.

SECTION 5: PROGRAMMING
5.1 INTRODUCTION
NOTICE
Although all IQ Transfer programmable features are
addressed in this section, only those ordered by the
customer and initially programmed at the factory
will appear in the display for programming changes
in the field.
The IQ Transfer is fully programmable from the device’s
faceplate or through the communications port. Users
can reprogram setpoints as well as other parameters.
The time and date can be changed while the device is in
either the Run Mode or the Program Mode. Setpoints,
however, can only be changed while the device is in the
Program Mode.
5.2 ENTERING AND EXITING THE PROGRAM MODE
NOTICE
While in the Program Mode, IQ Transfer is never offline and continues to function in accordance with
previously programmed setpoints.
NOTICE
If no pushbutton activity is detected for approximately 2 1/2 minutes while in the Program Mode, the
Setpoints LED is cleared and the alpha-numeric display is blanked. Any previously made setpoint
changes are not saved, should this occur.
NOTICE
When the toggle switch is in the Program position,
remote communications programming is inhibited.
To enter the Program Mode, move the Run/Program
Toggle Switch located on the right rear chassis to the
Program position. Once the Program Mode is activated,
the Program LED blinks red and continues until the
Program Mode is exited.
When programming changes have been completed, the
Program Mode is exited by moving the Run/Program
Toggle Switch back to the Run position. At that point,
the Automatic LED continues to blink green, the
alphanumeric display shows the word “Program” for a
short period, and the Program LED will no longer be illuminated. It is also at that point when any setpoint
changes are saved in the device’s non-volatile memory.
5.3 PROGRAMMING PROCEDURES
Once the Program Mode has been entered, use the
Display Select Pushbutton to move to the Setpoints
Display. The Setpoints LED will be lit red and the first
programming possibility will appear in the display. Use
the Step Pushbutton to move from one feature setpoint
to another, stopping at those in need of reprogramming.
Use the Increase or Decrease Pushbuttons to move the
display to a new setpoint selection. Once a new setpoint
selection has been made, move to the next feature in
need of change. Once all setpoints are displayed as
required, exit the Program Mode and the new setpoints
are automatically stored.
5.4 PROGRAMMABLE FEATURES/SETPOINTS
!
CAUTION
CHANGING THE SYSTEM NOMINAL VOLTAGE OR
FREQUENCY SETPOINTS WILL AUTOMATICALLY
CHANGE ALL THE PICKUP AND DROPOUT SETTINGS TO NEW DEFAULT VALUES.
