1 Introduction
inputs, and status reporting. The VFD’s logic circuitry is
1.1.1 Purpose of the Manual
backed up by an independent panel-mounted power
supply so that, even if the drive loses power, control and
communication functions are maintained. Programming
and display are provided by the keypad. An important
feature of the ECB is the ability to accept commands from
a building automation system (BAS) and to report
operational status in return.
This manual is intended to provide detailed information for
the installation and operation of the option panel used in
conjunction with a Trane variable frequency drive (VFD or
drive). To enable efficient handling of the equipment,
requirements are provided for installation of mechanical,
electrical, control wiring, proper grounding, and environ-
mental considerations. Pre-start and start up procedures
are detailed. Also included is a detailed overview of the
option panel bypass function. In addition, identification of
other optional components and their operation and start
up troubleshooting instructions are included. For the
electronically controlled bypass, additional programming
and operation information is provided.
See more detailed descriptions of the EMB2 in 5 Electrome-
Controlled Bypass (ECB) Operation of this manual.
1.1.3 Typical Bypass Operation
With contactors M1 and M2 closed and contactor M3
open, the motor is running in drive control. Opening
contactor M2 removes power to the motor but allows the
drive to remain under power. This is referred to as test
mode. With contactors M1 and M2 open and contactor M3
closed, the motor is running in bypass from the line input
power.
1.1.2 Overview
A variable frequency drive regulates the speed and
operation of an electric motor. The drive is programmable
and offers many features and savings compared to
operating a motor from unregulated line voltage. The
option panel is a protective enclosure in which the drive
and various optional components are assembled and
mounted. The vertical non bypass panel is always
configured with a disconnect switch and fuses to protect
the drive. The vertical bypass panel allows switching
between running the motor from the drive (variable speed)
or across the line input power (constant speed).
1.2 Bypass Circuits
1.2.1 Three-contactor Bypass
The bypass circuit consists of a bypass contactor (M3)
interlocked with a drive output contactor (M2), a drive
input contactor (M1), and an overload relay. For the EMB2,
a door mounted Drive/OFF/Bypass/Test Selector switch is
used to electrically select whether the motor is powered
by the drive, connected to the full speed bypass, or
disconnected from both. The test position applies power
to the motor through the bypass (M3 closed) contactor but
removes power from the drive (M2 open) while keeping
the drive powered (M1 closed). A Pilot light indicates when
in bypass. For the ECB, control selection is made through
the drive keypad by pressing the DRIVE BYPASS key and
selecting from the available options shown. Display data
indicates when in bypass. The circuitry may be supplied
with either an input disconnect switch or an input circuit
breaker.
The vertical bypass panel comes with one of two control
options:
The electromechanical bypass (EMB2)
•
•
Electronically controlled bypass (ECB)
The EMB2 is operated by a selector switch on the front of
the panel. The EMB2 controls a motor by switching
between drive control, operation in bypass, or off. In
addition, a test selection is available, which disengages the
motor from the drive but keeps the drive operational while
the motor runs in bypass. The switching function activates
contactors to provide power to the motor through the
drive or bypass circuitry, as required.
The ECB also uses contactors to provide power to the
motor through the drive or bypass circuitry. However, the
ECB contains a local processor that interacts with the
drive’s control logic for programmable options, remote

1.3.4 Basic Fire Mode in Bypass
1.3 Bypass Options
This option switches the panel to bypass whenever a
remote fire mode signal is given to the VFD through the
input terminals. In either drive or bypass, fire mode is
intended to ignore common safety and overload inputs for
emergency situations. The motor will continue to run in
bypass until fire mode is removed or the drive, panel, or
motor fails. External safety signals and motor overload are
ignored when in fire mode.
1.3.1 Common Run/Stop with Bypass
Allows a remote signal to initiate operation in either drive
control or bypass depending upon the position of the
bypass selector switch.
1.3.2 Automatic Bypass
1.3.5 Advanced Fire Mode in Bypass
This feature automatically transfers the motor from drive to
bypass without operator intervention when a fault
condition trips the drive, after a programmable time-out
period. The VFD’s internal fault circuitry controls this
action. The time delay permits all automatically resettable
faults to clear prior to transfer to bypass. Run permissive or
safety circuit signals override the auto bypass function and
may prevent or delay bypass operation.
The advanced fire mode allows for a variety of
programmable responses to an external fire mode
command signal. Bypass options are programmed through
the drive’s fire mode parameters. See 6.1.13 ECB Advanced
1.3.6 Overload Protection
1.3.3 Run Permissive in Bypass
This thermally activated device provides mechanical
overload protection for the motor while in bypass
With run permissive active, the drive sends a run request
and waits for a remote response before commanding the
motor to start. The response indicates the system is safe to
operate.
operation. It measures motor current and is set to the full
load amps (FLA) of the motor. A 1.2 x FLA service factor is
built-in and maintained, meaning that should the motor
current increase above that value, the overload will
calculate the level of increase to activate timing for the trip
function. The higher the current draw, the quicker the trip
response. The overload provides Class 20 motor protection.

1.5.1 Control Transformer
1.5 Switch Mode Power Supply
A control transformer is included on larger horsepower
units where the contactor coils are AC. The control
transformer steps down the line input voltage to 120V AC.
The coils of AC contactors are isolated from the Switch
Mode Power Supply via relays.
The VFD’s logic circuitry is backed up by an independent
panel-mounted switch mode power supply so if the drive
loses power, control and communication functions are
maintained. The SMPS converts three-phase AC input
power to 24 V DC control power. Since the SMPS draws
power from all three phases, it offers immunity protection
from most phase-loss and brown-out conditions. The SMPS
is internally protected from short circuit on its output and
three board-mounted fuses provide additional protection.
The SMPS is not designed for external use and may take
up to 5 sec. to initialize at power-up. The SMPS will
maintain a 24 V DC output with a low input line voltage.
The 200 Volt SMPS will maintain the 24 V DC output with
a line voltage as low as 150 V AC and the 600 V SMPS to

1.6.2 Mode Selector Switch
The mode selector switch is used for 3-contactor bypass
on EMB2 units. The selector switch allows the operator to
select from four modes of operation.
Drive mode: When drive mode is selected, the M1 and M2
contactors are closed allowing power to flow in and out of
the drive to the motor.
Off mode: This mode opens all contactors removing any
power to the motor.
Bypass mode:When bypass mode is selected, the M3
contactor closes and allows the motor to run directly from
the input line power.
Test mode:Test mode closes the M1 and M3 contactors
and allows the motor to be powered by the input line
power. This also allows the drive to power up without

IMPORTANT LOST OR DAMAGED GOODS INSPECT THIS
SHIPMENT IMMEDIATELY UPON ARRIVAL If goods are
received short or in damaged condition, insist on a
notation of the loss or damage across the face of the
freight bill. Otherwise no claim can be enforced against
the transportation company. If concealed loss or damage is
discovered, notify your carrier at once and request an
inspection. This is absolutely necessary. Unless you do this
the carrier will not entertain any claim for loss or damage.
The agent will make an inspection and can grant a
concealed damage notation. If you give the transportation
company a clear receipt for equipment that has been
damaged or lost in transit, you do so at your own risk and
expense.

2.1.3 Installation Site Check
Because the option panel relies on the ambient
•
air for cooling, it is important to observe the
limitations on ambient air temperature. Derating
concerns start above 104°F (40°C) and 3300 feet
(1000m) elevation above sea level.
Figure 2.1 Sample Panel Label
It is important with multiple panels to check wall
strength. Make sure that the proper mounting
screws or bolts are used.

dirt. If the unit does not have power applied to it,
supply a protective covering. It is important to
ensure that the components stay as clean as
possible. It may be necessary to clean the interior
once construction is completed.
Keep drawings and manuals accessible for
detailed installation and operation instructions. It
is important that the manuals be available for
equipment operators.
•
2.2 Harsh Environments
NOTE!
The mechanical and electrical components within the
option panel can be adversely affected by the
environment. The effects of contaminants in the air, either
solid, liquid, or gas, are difficult to quantify and control.
2.2.1 Airborne Liquids
Liquids in the air can condense in components. Water
carried in the air is easily measured as relative humidity,
but other vapors are often more difficult to measure or
control. Steam, oil and salt water vapor may cause
corrosion of components. In such environments, use TYPE
12 enclosures to limit the exchange of outside air into the
option enclosure. Extremely harsh environments may
require a higher level of protection.
2.2.2 Airborne Solids
Particles in the air may cause mechanical, electrical or
thermal failure in components. A TYPE 1 enclosure
provides a reasonable degree of protection against falling
particles, but it will not prevent the fan from pulling dirty
air into the enclosure.
2.2.3 Corrosive Chemicals
In environments with high temperatures and humidity,
corrosive gases such as sulfur, nitrogen and chlorine
compounds cause corrosion to occur in components.
Indications of corrosion are blackened copper or rust on
steel or oxidized aluminum. In such environments, it is
recommended that the equipment be mounted in a
cabinet with fresh air ventilation and that corrosive
compounds be kept away. A non-ventilated cabinet fitted
with an air conditioner as a heat exchanger may be used.
Conformal coated circuit boards may be specified to
reduce the corrosive effects of a harsh environment.

WARNING
INDUCED VOLTAGE!
WARNING
Run output motor cables from multiple drives separately.
Induced voltage from output motor cables run together
can charge equipment capacitors even with the equipment
turned off and locked out. Failure to run output motor
cables separately could result in death or serious injury.
Hazardous Voltage!
Disconnect all electric power, including remote disconnects
before servicing. Follow proper lockout/tagout procedures
to ensure the power cannot be inadvertently energized.
Failure to disconnect power before servicing could result in
death or serious injury.

4.1.1 Inspection Prior to Start Up
Inspect For
Description
Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may reside on input
power side of drive or output side to motor. Examine their operational readiness and ensure they are ready in
all respects for operation at full speed. Check function and installation of pressure sensors or encoders (etc.)
used for feedback to drive. Remove power factor correction caps on motor, if present.
Ensure that input power, motor wiring, and control wiring are in three separate metallic conduits for high
frequency noise isolation. Failure to isolate power, motor, and control wiring could result in less than optimum
drive and associated equipment performance.
Auxiliary equipment
Cable routing
Control wiring
Check for broken or damaged wires and connections. Check the voltage source of the signals, if necessary. The
use of shielded cable or twisted pair is recommended for serial communication. Ensure the shield is terminated
correctly.
EMC considerations
Environmental
conditions
Check for proper installation with regard to electromagnetic capability.
See panel label for the maximum ambient operating temperature. Humidity levels must be less than 95% non-
condensing. Attitude less than 3300 feet.
Fusing and circuit
breakers
Check that all fuses are inserted firmly and in operational condition and that all circuit breakers are in the open
position.
The panel requires a dedicated ground wire from its chassis to the building ground. It is required that the
motor be grounded to the panel chassis. The use of conduit or mounting of the panel to a metal surface is not
considered a suitable ground. Check for good ground connections that are tight and free of oxidation. Run
insulated motor ground wire back to panel in conduit with motor wires.
Grounding
Input and output
power wiring
Check for loose connections. Check for proper fusing or circuit breakers.
Panel interior must be free of dirt, metal chips, moisture, and corrosion. Check for harmful airborne contam-
inates such as sulfur based compounds.
Panel interior
Proper Cooling
Clearance
Switches
Panels require top and bottom clearance adequate to ensure proper air flow for cooling. See Figure 3.2 and
Ensure that all switch and disconnect settings are in the proper position.
Look for any unusual amount of vibration the equipment may be subjected to when mounting panel.

Ensure that all operator devices are in the OFF
position. The main disconnect switch on the front
of the electromechanical bypass panel must be in
the OFF position. The panel door should be
closed.
In the following procedures, changing the equipment
between drive mode and bypass mode is required.
Changing modes is different for the ECB and EMB2. The
ECB uses pushbuttons on the drive keypad while the EMB2
uses a selector switch on the front of the panel. Be familiar
with the operation of these devices prior to start up.

5.1.2 EMB2 Auto Bypass
•
•
•
•
•
General Information
Auto bypass allows a fault condition in the drive to
activate running the motor in bypass without operator
intervention. Activation of the function is through setting
DIP switches (S100) located on the EMB2 bypass control
timer prior to tripping the drive into bypass. The fault trip
and running in bypass are reported as output from the
bypass control card. The auto bypass function is built in.
5.1.3 EMB2 Common Run/Stop
General Information
The common run/stop function provides remote run and
stop control of the motor in bypass. Without common run/
stop, the motor would automatically run at full speed
whenever the bypass is activated. The remote signal
provides drive control as well as bypass control, making
this one input common to both. Common run/stop is
enabled by factory default. When used with the run
permissive function, common run/stop permits run request
operation in bypass.
Prior to Enabling Auto Bypass
Complete the start-up procedure to verify that
•
the motor rotation direction in bypass is correct
and that the system is ready in all respects for
continuous full speed operation in bypass.
WARNING
HAZARDOUS VOLTAGE!
Remove power to the bypass panel before setting auto
bypass dip switch settings. Bypass can contain high
voltage. Failure to remove power to bypass panel before
setting dip switches could result in death or serious injury.
Prior to Enabling Common Run/Stop
Complete the start-up procedure to verify motor
•
rotation direction in bypass is correct and that
the system is ready in all respects for continuous
full speed operation in bypass.
Operation
Operation
With the bypass selector switch in drive and auto
bypass enabled, a fault signal from the drive will
activate the auto bypass timer.
•
A user supplied remote start command wired to
•
connector X55, terminals 3 and 4 initiates remote
bypass operation. With common run/ stop,
bypass mode cannot be activated by hand on the
drive keypad or by serial communication.
If the fault clears before the time delay is
•
complete, the motor remains operating in drive
mode. This allows temporary faults, such as a
momentary under or over voltage, to clear
without transferring the system to bypass.
Common Run/Stop Setup
Wire input terminals 3 and 4 on connector X55
per the system application.
•
If the timer completes its cycle before the fault
•
clears, the panel trips into bypass mode and the
motor runs at constant full speed from line input
voltage.
To Disable Common Run/Stop
Common run/stop is enabled by factory default
when ordered.
•
In bypass, the motor will stop if safety or motor
overload conditions are exceeded.
•
To disable the feature, turn switch four on dip
•
switch S105. This allows the bypass to start when
the bypass switch is placed in the bypass
position.
Once auto bypass is activated, the only way to
•
reset the unit back to drive is by operator
intervention. Ensure that the fault has been
cleared, then rotate the bypass switch to the OFF
position momentarily before setting it back to the
drive position. This resets the drive and fault
timer.
Remove wire from terminal 18 of the drive
•
control terminal and insulate the end of the wire
to prevent shorting. This is required or the drive
will always have a run command.
If applicable, connect remote run/stop input to
terminals 12 and 18 on the drive control card.
•
Auto Bypass Function Setup
Enable auto bypass by closing one or more DIP switches
on switch S100 located on the bypass control card. (Times
are approximate.)

5.1.4 EMB2 Run Permissive
5.1.5 EMB2 Overload
General Information
General Information
Run permissive allows a remote signal to notify the drive
to start, indicating the system is safe to operate. Run
permissive works in drive or bypass mode. Run permissive
is enabled by factory default and can be disabled by
switching dip switch #4 on S105 to the on position or
placing a jumper wire between terminal 1 and 2 of the
X55 customer connector.
The overload device provides overcurrent protection for
the motor when running in bypass. The thermally activated
overload monitors motor current and trips to remove
power to the motor if a sustained over-current condition
exists. A Class 20 overload is standard with a variable
setting for motor current. Test and reset buttons are also
provided. In drive mode, the drive provides current sensing
and trip protection. Fuses provide quick action for high
over current conditions.
Prior to Enabling Run Permissive
Complete the start-up procedure to verify that
•
Prior to Enabling Overload

programming the run permissive function.
Operation
A start command can be from local hand start on
•
the drive keypad or a remote auto start signal
through digital input connector X55 terminals 3
and 4, or via the serial communications input.
CAUTION
MOTOR DAMAGE!
Repeated attempts to reset an overload can cause motor
damage. Correct the overload condition and let the
overload and motor return to normal operating
temperature before resetting. See motor manufacturer’s
recommendations for time between start attempts. Failure
to correct the overload condition and let the motor return
to normal operating temperature could cause motor
damage.
In response to a start command, an output
•
request is sent from X55 terminals 11 and 12 to
the external equipment (to activate a valve or
damper, for example).
When a return run signal on X55 terminals 1 and
•
2 is received, the motor is started in either drive
or bypass mode, depending upon the bypass
switch position.
Operation
Run Permissive Function Setup
Overloads are rated by class. The class is defined by the
NEC to determine the maximum time to trip. A Class 20
overload, for example, has a typical trip delay of 20 sec. or
less at 600% current and normal operating temperature.
This allows for high motor inrush current for 20 sec. while
the motor is ramping up to synchronous speed. The trip
time, however, is based on the percentage of overload.
The higher the overload, the shorter the trip time. It is
important that the overload class not exceed the motor
class rating or motor damage could occur.
Remove the factory-installed jumper wire on
connector X55, terminals 1 and 2.
•
Wire the output run request to connector X55,
terminals 11 and 12.

5.1.7 EMB2 Fire Mode
General Information
Reset is used to reset the overload after it trips. If
the overload is still hot, wait until the motor
reaches normal operating temperature before
resetting. The overload offers a manual (hand) or
auto reset selection. It is highly recommended to
operate in the manual factory setting to prevent
the risk of damage to the motor.

5.1.6 EMB2 Safety Interlock
Fire mode status can be reported through
•
connector X55, terminals 9 and 10, a normally
open dry contact that closes when fire mode is
active.
General Information
The safety interlock feature prevents the drive or bypass
from operating. For operation in drive or bypass, the safety
interlock input contact must be closed. Only a fire mode
command to run in bypass overrides this function. Safety
inputs include, but are not limited to, high and low
pressure limit switches, fire alarm, smoke alarm, high and
low temperature switches, and vibration sensors.
Fire Mode Function Setup
Wire the fire mode input to connector X55,
terminals 7 and 8.
•
Wire the fire mode status output to connector
X55, terminals 9 and 10.
•
Operation
When an external safety input closes, the panel is in
operational mode. When open, power is interrupted to the
drive output and bypass contactors and relays, and the
bypass ignores all run commands except for fire mode
operation. When power is interrupted in drive mode, the
drive display indicates an external fault, meaning the
problem is external to the drive. In some instances, a fault
can be caused by a failure within the panel, which will still
be reported as an external fault from the drive. A factory
installed jumper allows the unit to operate when no safety
input is connected. This jumper must be removed when
connecting a safety interlock in the circuit.
5.1.8 EMB2 Fault Reporting
General Information
A fault indication is provided if the drive experiences a
fault or bypass input power is lost. The EMB2 bypass
control card monitors the drive fault output for status
reporting. The fault contacts are fail-safe, meaning that if
power is removed, a fault condition is automatically
reported. Fault status is not monitored in bypass
operation.
Operation
For the EMB2, fault reporting is monitored through a
Form-C relay (RL2) on the bypass control board. The relay
reports a fault on connector X59 terminals 5, 6, and 7. In
normal operation, the relay is powered and terminal 5 is
closed with terminal 7 open. In a fault condition, power to
the relay is lost and the relay positions automatically
reverse, signaling the fault condition. Terminal 6 is
common to both.

Information provided in this section is intended to enable
the user to connect control wiring, program functions, and
operate the ECB and its optional features.
An important feature of the ECB is the ability to accept
commands from a building automation system (BAS) and
to report operational status in return.
The ECB contains a local processor located on the ECB
control card, which interacts with the drive’s control logic
for programmable options, remote command input, and
output status reporting. Rather than panel-mounted
operator-activated selector switches, as on the electrome-
chanical option panel, ECB control is provided by the
drive’s processor.
Control wiring connections are made to either the drive’s
digital I/O terminals are multifunctional and need to be
programmed for their intended use while the terminals on
the ECB control card are dedicated for specific functions.
The ECB also contains a power supply which provides back
up for the drive’s logic circuitry, so even if the drive loses
power, the control and communication functions are
maintained.
Programming options for drive terminals are seen by
pressing the [Main Menu] key or [Quick Menu] key on the
keypad keypad. Parameter menus appear in the keypad
display. The arrow keys are used for navigating through
the parameter lists. Terminal functions are programmed in
parameter settings for drives with an ECB.) Bypass
functions are programmed in parameter group 31-** (see
Table 6.4). See the drive’s supporting materials for detailed
programming instructions.

6.1.10 ECB Overload
6.1.9 ECB Run Permissive
General Information
General Information
An overload device provides overcurrent protection for the
motor when running in bypass. The thermally activated
overload monitors motor current and trips to remove
power to the motor if a sustained overcurrent condition
exists. A Class 20 overload is standard with a variable
setting for motor current. Test and reset buttons are also
provided. In drive mode, the drive provides current sensing
and trip protection. Fuses provide quick action for high
over current conditions.
With run permissive active, the drive sends a run request
and waits for a remote response before notifying the
motor to start. The response indicates the system is safe to
operate. Run permissive operates from the keypad
hand/off/auto select in drive or bypass mode. Run
permissive is enabled by programming in the drive
parameters.

of the current dial, reconfirm that the motor HP
and voltage are within the option panel (and
drive) rating. If greater than the FLA rating,
replace the panel with one of a proper rating.
Operation
A start command can be initiated from local hand
start, serial communications, or a remote auto
start signal through digital drive input terminals.
•
CAUTION
MOTOR DAMAGE!
Repeated attempts to reset overload can cause motor
damage. Correct the overload condition and let the
overload and motor return to normal operating
temperature before resetting. See motor manufacturer’s
recommendations for time between start attempts. Failure
to correct the overload condition and let the motor return
to normal operating temperature could cause motor
damage.
In response to the start command, an output
•
request is sent from the programmable drive
relay to the external equipment (to activate a
valve or damper, for example).
When a return run signal on the digital input is
received, the motor is started in either drive or
bypass, depending upon which mode is active.

Operation
bypass ignores all run commands except for fire mode
operation, when applicable. The drive display indicates
alarm 221, bypass interlock, meaning the problem is
external to the drive. A factory installed jumper between
X57 terminals 1 and 2 allows the unit to operate when no
safety input is connected. This jumper must be removed
when connecting in a safety interlock circuit.
Overloads and motors are both rated by class. The class is
defined by the NEC to determine the maximum time to
trip. A Class 20 overload, for example, has a typical trip
delay of 20 sec. or less at 600% current and normal
operating temperature. This allows for high motor inrush
current for 20 sec. while the motor is ramping up to
synchronous speed. The trip time, however, is based on
the percentage of overload. The higher the overload, the
shorter the time.

The common run/stop function provides remote run and
stop control of the motor while in either drive or bypass.
Without common run/stop, the motor would automatically
run at full speed whenever the bypass is activated. The
remote signal provides drive control as well as bypass
control, making this one input common to both. Common
run/stop is enabled by factory default. When used with the
run permissive function, common run/stop permits run
request operation in bypass.
Pressing the test pushbutton verifies the
operation of the overload. The overload should
trip when pressed. Use the reset pushbutton to
reset the overload after testing.
Reset is used to reset the overload after it trips. If
the overload is still hot, wait until the motor
reaches normal operating temperature before
resetting. The overload offers a manual (hand) or
auto reset selection. It is highly recommended to
operate in the manual factory setting to prevent
the risk of damage to the motor.
Operation
A user supplied remote run command wired to drive
terminals 13 and 18 initiates remote drive or bypass
operation. Common run/stop can also be activated by
hand on the keypad or through serial communication.
Operation in either drive or bypass is determined by drive
or bypass mode selection, not the run/stop command.

6.1.14 ECB Fault Reporting
General Information
The ECB monitors bypass contactors M2 and M3 and
reports failures to the drive for display and external
reporting. The drive also monitors the ECB card for bypass
communication errors.
Operation
ECB detected faults are reported by the drive in three
ways: Warnings and alarms are displayed on the keypad
display, through serial communication, or through output
relays. The drive provides a form-C fault relay on terminals
01, 02, and 03. The fault contacts are fail-safe, meaning
that if power is removed the contacts close and a fault
condition is reported.
