Introduction
This Section describes the applicability of the Manual
Product Description
The E7L Bypass unit provides a means of bypassing the Drive while allowing the motor to operate at full speed, directly from
the AC line. It incorporates an AC Drive and two contactor Bypass arrangement in a single UL listed enclosure. The two
electrically interlocked IEC rated contactors isolate the Drive from the load when operating in B y p as s m o de .
Control logic provides industry standard Hand/Off/Auto functions and safety circuit interlocks in both drive and Bypass
op eratin g modes.
E7L Bypass components include: a fused 120 VAC control circuit transformer, an input disconnect, motor overload relay,
control keypad and indicating lights.
The E7 Drive, a component of the E7L Bypass package, is a Pulse Width Modulated Drive for 3-Phase AC induction motors.
This type of Drive is also known as an Adjustable Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD,
and Inverter. In this manual, the E7 Drive will be referred to as the “Drive”.
The Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation, including fans,
blowers and pumps. A new benchmark for size, cost, performance, benefits, and quality, the Drive includes numerous
built-in features such as network communications, H/O/A, PI, parameter storage and copy functions.
The Drive has embedded communications for the popular building automation protocols, Johnson Controls Metasys® N2 and
Siemens APOGEE™ FLN, as well as Modbus®. An optional LONWORKS® interface card is also available.
The LED keypad/operator is equipped with Hand/Off/Auto functions and copy feature. User parameter settings can be recovered at any time via “User Initialization”. Optional DriveWizard software allows upload/download, as well as graphing and
monitoring of drive parameters from a PC for ease of drive management.
Built-in PI control eliminates the need for closed loop output signals from a building automation system. It includes feedback
display, inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and
pumps for pressure, flow, or temperature regulation.

Bypass Unit Enclosures
All Bypass units are intended for non-hazardous locations. Various enclosure types are provided to protect against the application environmental conditions:
Nema Type 1 Enclosures
These are constructed for indoor use to provide a degree of protection against incidental contact with enclosed electrical equipment and falling dust or dirt.
NEMA Type 12 FVFF Enclosures
NEMA provides for both non-ventilated and ventilated NEMA 12 enclosures. When ventilated, a suffix to the type number
defines the ventilation method. A NEMA 12 FVFF enclosure has Forced Ventilation with inlet air Filter and outlet air Filter.
The internal pressure is positive with respect to the ambient pressure. UL does not recognize NEMA 12 ventilated enclosures,
therefore, these enclosures are designated NEMA 1 for UL purposes.

Bypass Product Options
Option C
Motor Circuit Protector (MCP)/Disconnect: Replaces the standard input disconnect switch and provides short circuit protection
integral with the Drive and Bypass package. The MCP includes a through the door, padlockable operator mechanism. Without
this option, short circuit protection must be provided by others on the input side of the Drive and Bypass unit.
Option F
Drive Input Fuses: Fuses capable of protecting semiconductor devices, rated at 200 kAIC are connected to the line side of the
Drive, between the input disconnect and the Drive, to protect the Drive semiconductors when motor or output conductor short
circuit faults occur.
Option G
Drive Input Disconnect Switch: Provides a disconnect means for the input side of the Drive, for Drive isolation capability
during Bypass operation. This disconnect is located inside the enclosure with no external handle.
Option H
Drive Input Fused Disconnect Switch: Provides both a disconnect means and short circuit protection for the input side of the
Drive. A combination of options F and G.
Option J
Enable Embedded Serial Communications: A no cost option. The Drive in a Bypass unit is capable of network communication
via one of 3 embedded protocols. Specifying option J will enable the Metasys N2 protocol and will provide the necessary
parameter settings and wiring (jumpers) to be network ready when delivered (Project specific H5-0X parameters are setup by
the user).
Option L
Serial Communication, Echelon LonWorks: An isolated RS-422/485 circuit board provides LonTalk protocol for network
communication to a BAS. This option plugs into the CN2 connection on the Drive control circuit board.
Option N
Input Capacitive Network Radio Frequency Interference Filter: Electronic equipment can be sensitive to low levels of voltage
distortion and electrical noise. This passive wye-delta capacitve filter is intended for installation on the VFD input in order to
protect other sensitive electronic loads, it provides attenuation of conducted RFI and EMI.
Option P
Pressure to Electrical Transducer: This transducer is employed when converting a pneumatic signal to an electrical signal for
use as the Drive speed command input. The need for this option comes up on retrofit applications when the pneumatic signal
that formerly controlled the pneumatic actuator on Inlet Guide Vanes (IGV), for example, is now to be used to control the fan
speed via the Drive. This option is wired to terminals TB5-7, TB5-8 and TB5-9, parameters H3-10 and H3-11 are used for
final field calibration of this input if there is jobsite variation from the typical 3 to 15 PSIG pneumatic signal input range.
Option R
3% Input Line Reactor: Employed on the input side of the Drive for Total Harmonic Distortion (THD) suppression. A line
reactor also minimizes the potential for Drive input diode damage from line transients and reduces voltage peaks on the DC
bus capacitors. This option is installed on the input power side of the Drive, between the input contactor and the Drive.

Electrically located on the input power side of the Bypass unit, the disconnect provides a through the door padlockable operator
mechanism. The Bypass three phase input power connection is made to the input terminals of the disconnect. The door mounted
rotary operating mechanism is a convenient means of disconnecting the Bypass unit from line power for equipment maintenance.
The disconnect must be in the OFF position in order to open the enclosure door. The rotary handle can be padlocked in the OFF
position.
This disconnect switch DOES NOT provide branch short circuit protection. A device to provide branch short circuit protection
MUST be provided by others upstream of the E7L Bypass unit.

Contactors
The Bypass is a “2 contactor Bypass” circuit employing IEC rated contactors in an electrically interlocked arrangement to
allow mutually exclusive operation in Drive or Bypass modes. To minimize enclosure space requirements, they are mounted in
a 2 contactor assembly.
The control logic and “soft start” characteristic of the Drive limit the Drive input and output contactors to motor FLA current or
less. For this reason, the Drive output contactor has a lower current rating than the Bypass contactor. The Bypass contactor is
exposed to motor inrush current (LRA) when starting the motor across-the-line and therefore requires a higher current rating.
OverLoad Relay
The OverLoad Relay (OLR) is mounted to the contactor assembly or back panel (depending on rating), just above the Bypass
contactor (see Figure 1.7). Electrically on the output power side of the Bypass unit, the adjustable thermal OLR provides
overload protection for the motor in both the Drive and Bypass operating modes. The Bypass three phase output power
connection to the motor is made to the output terminals of the overload relay. The OLR is set up in the factory to be a manual
reset device, requiring operator attention if an overload trip-out is experienced.
Control Power Transformer
A Control Power Transformer (CPT) is provided to power the Bypass 120 VAC control circuit. The VA capacity is determined
by the control circuit and optional functions specified for the unit. The CPT primary is fused in both legs, the secondary is
fused when required by NEC (transformer VA and wire size dependent). One side of the transformer secondary is grounded to
the Bypass enclosure.
Electronic Bypass Control Logic
Operating elements such as indicating LEDs and selector buttons, as well as the control logic, have been incorporated into a
PCB assembly to eliminate the potential for loose wires after shipment and to control factory costs.
The operating elements are located on PCB A3, mounted to the inside of the enclosure door and ribbon cable connected to the
control logic PCB A2.
The control logic PCB A2 is mounted to the left hand side of the enclosure and contains the control circuit field wiring terminal strips (TB1 through TB5).
Drive/Bypass logic interlocks explained
The Bypass 120 VAC logic circuit is interconnected with the Drive multi-function digital input terminals and multifunction digital output terminals to allow a single customer interface to control both Drive and Bypass circuits. These Drive
terminals are therefore not available for other field use. All field control connections are landed at terminal strips TB1 through
TB5 on control logic PCB A2.
PCB Jumpers explained
J1 is a field configuration jumper to allow the user to select the internal 120 VAC power supply, a customer supplied 120 VAC
power supply or a customer supplied 24 VDC power supply for the digital inputs.
J2 and J3 are field configuration jumpers to allow the user to select the signal level (0 to 10 VDC or 4 to 20 mA) for the two
analog output signals.
Physical Installation 1 - 13
DIP Switch Selectable Functions:
The DIP switches used to select these functions are located on the logic controller Printed Circuit Board (PCB) A2 (See Figure
1.9). The factory default is shown on the wiring diagram in Chapter 2 or Schematic diagram E7L-00.
DIP switches S1, S2, S3 and S4 allow the user to configure various project specific functions of the E7L including:
• Serial Communication terminating resistor
• Speed command source
• Analog input signal level
• Activate or inactivate functions:
Auto transfer to Bypass on Drive Fault

Physical Installation 1 - 18
Checking and Controlling Installation Site
Install the Bypass unit as described below and maintain the specified operating conditions.
Installation Site
Location of the Bypass unit is important to achieving proper performance and design operating life. Install the Bypass unit as
close as possible to the motor. The NEMA type 1 & 12 enclosed units should be installed in an area where it will be protected
from: Direct sunlight, rain or moisture, corrosive gasses or liquids, vibration and dust or metallic particles. The ambient air
available for cooling the unit should be 104° F (40° C) or less.
Wall mount units require a minimum 6 inch clearance above and below, to achieve adequate heat sink cooling.
No side clearance is required for cooling because the cooling air flow is in and out of the enclosure door at the front surface of
the unit (do not block the air flow louvers). Clearance for the opening swing of the enclosure door should be considered when
placing these units. The door is hinged on the left and must open through at least a 90 degree swing with a 120 to 180 degree
swing being preferable (minimum clearance is 1.5”).
Install the Bypass unit under the following conditions in UL pollution degree 1 & 2 environments. This excludes wet locations
where surfaces may become conductive due to moisture and contaminant loading.
NEMA Type 1 & 1214 to 104°F (-10-to-+ 40°C)95%-RH-or-less-(no-condensation) Ye s
Observe the following precautions when mounting the Bypass unit.
• Install the Bypass unit in a clean location that is free from oil mist and dust.
• Install the Bypass unit in an environment where metal shavings, oil, water, or other foreign matter will not get into the
Bypass enclosure.
• Install the Bypass unit in a location free from radioactive materials.
• Install the Bypass unit in a location free from harmful gasses and liquids.
• Install the Bypass unit in a location without excessive vibration.
• Install the Bypass unit in a location free from chlorides.
• Install the Bypass unit in a location not in direct sunlight.
• Install the Bypass unit on a non-combustible surface.
Physical Installation 1 - 19
Controlling the Ambient Temperature
To enhance the reliability of operation, the Bypass unit should be installed in an environment free from extreme temperature
variations. Do not store this Technical Manual or any other documents on the top surface of the Bypass unit, they may cover
the heat sink cooling air discharge opening and cause the unit to overheat.
If the Bypass unit is installed in an enclosure (such as an electrical control box in an air handling unit), use a cooling fan or air
conditioner to maintain the Bypass unit internal air temperature below 113°F (45°C).
Protecting the Bypass Unit from Foreign Matter
During Bypass unit installation and project construction, it is possible to have foreign matter, such as metal shavings or wire
clippings, fall inside the Bypass unit. To prevent foreign matter from falling into the Bypass unit, place a temporary cover over
the unit.
Always remove the temporary cover from the Bypass unit before start-up. Otherwise, ventilation will be reduced, causing the
Bypass unit to overheat.
Installation Orientation and Enclosure Considerations
Install the Bypass unit vertically so as not to reduce the cooling efficiency. When installing the Bypass unit, always provide the
recommended installation clearances to allow normal heat dissipation.
When preparing to mount the unit, lift it by the base (or lifting rings when provided), never by the enclosure door. For effective
cooling and proper maintenance, the wall mounted units must be installed on a flat non-flammable vertical surface using four
mounting screws.
For all units, the Disconnect handle should be in the OFF position to open the enclosure door. The wall mount units have two
full turn fasteners, CCW to open, that require a flat blade screwdriver to open the enclosure door.

WARNING
Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line
voltage drop is calculated as follows:
Line voltage drop(V) = √3 x wire resistance (Ω/km) x wire length (m) x current (A) x 10
Prior to removing any protective cover or wiring any part of the Drive, remove all power sources, including
main input power and control circuit power. Wait a minimum of 5 minutes after power removal, before
removing any cover. The charge lamp located within the Drive should be off prior to working inside. Even if
the charge lamp is off, one must measure the AC input, output, and DC Bus potential to insure safe levels
prior to resuming work. Failure to adhere to this warning may result in personal injury or death.
Electrical Installation 2 - 3

Cable Length between Drive and Motor
The Bypass unit should be installed as close as possible to the motor to minimize the length of load side power cable needed
between the Drive and the motor. If the cable between the Drive and the motor is long, the high-frequency leakage current will
increase, causing the Drive output current to increase as well. This may affect peripheral devices. To prevent this, reduce cable
length, or if necessary, adjust the carrier frequency (set in C6-02) as shown in Table 2.1.
The line side power cables, load side power cables and the control wiring should all be run in a separate conduit. Careful
attention to this recommended design practice will avoid many potential motor and Drive related problems.

Grounding
NO
Drive and Motor Ground Wire Landing
The Drive ground lug (terminal ) is connected to the enclosure. The enclosure ground lug must be connected to earth
ground. See Figure 2.1.
The Drive has a second ground lug to accept the motor ground lead.
Ground Wiring Precautions
Observe the following precautions when connecting the ground wire:
1.208-240 VAC Drives should have a ground connection with resistance of less than 100 Ω..
2.480 VAC Drives should have a ground connection with resistance of less than 10 Ω..
3.Do not share the ground wire with other devices, such as large-current electrical equipment.
4.Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the
ground wire. Leakage current flows through the Drive. Therefore, if the distance between the ground rod and the ground
terminal is too long, potential on the ground terminal of the Drive will become unstable.
5.When using more than one Drive, be careful not to loop the ground wire.

Control Circuit Ground Terminals
The control logic PCB A2 provides a ground terminal (marked PE) to accept the control wire shield connection. Terminal PE
is located at the top left of PCB A2, near TB4. The control wire shield should be connected on this end only, the opposite end
should be isolated with electrical tape.

Control Circuit Analog Input Terminals on PCB A2
All control inputs are landed on TB1 through TB5 on PCB A2.
TB3-3 is an analog input terminal and may be connected to either Drive terminal A1 or Drive Terminal A2, to maximize input
flexibility, using DIP switches S1-3 and S1-4. The factory default is TB3-3 connected to Drive terminal A2. With this
connection, the input signal level can be either 0 to 10 VDC or 4 to 20 mA. The signal level selection is controlled by DIP
switch S1-2 and Drive parameter H3-08.
TB5-9 is also an analog input terminal, it is always connected to Drive terminal A2.
See Table 2.8, Figure 2.7 and Schematic Diagram E7L-00 for clarification of the analog input configuration and applications.

Analog Input (Drive Speed Control Circuit) Wiring
Keep this lead length as short as possible (50 m max.) to maintain signal quality. Insulated twisted shielded pair wire (2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same conduits as other AC power or control wires. The shield must be connected on this end only, stub and isolate the other end. The signal employed is 4 to 20 mA
with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for “0: 0 - 10 VDC” and the control
PCB DIP switch S1-2 must be in the OFF position.
When setting speed commands from an external speed potentiometer (and not from a Digital Operator), use shielded twisted-
pair wires and ground the shield to terminal PE, as shown in Figure 2.8. Terminal numbers and wire sizes are shown in
Table 2.13.

Analog Outputs
Two analog outputs are provided, both can be configured for a signal level of 0 to 10 VDC or 4 to 20 mA. The signal level is
controlled by the position of jumpers J2 and J3 (see Figures 1.8 and 1.9 for location) on Control PCB A2 and by the values
selected for Drive parameters H4-07 and H4-08.

Electrical Installation 2 - 13
Serial Communications:
Terminals are provided for “full duplex” or “half duplex” connections to the Drive for RS422/RS485 serial communication.
For “half duplex” operation via Metasys N2 protocol (enabled with option J), APOGEE FLN protocol (enabled with option U)
or Modbus protocol (enabled with option V) field configuration of these terminals is required.
When no cost options J, U or V are ordered:
•Jumpers are provided for field installation on terminals TB4-1 to TB4-3 and TB4-2 to TB4-4.
•The E7 Drive is programmed to enable the appropriate protocol (parameter H5-08), baud rate (parameter H5-02),
RTS control (parameter H5-07) and error detection time (parameter H5-09).
Option L (LonWorks) does not require jumpers and (with the exception of H5-07) employs the same parameter settings as
Modbus.

For co-ordination with other E7 Technical Manuals, the table below provides the equivalency between E7L Control PCB A2
terminal designations and E7 Drive terminal designations used in TM.E7.01, TM.E7.02, TM.E7.21, TM.E7.22 and

Remote Transfer to Bypass
Terminal TB1-4 on the Control PCB A2 is a dedicated terminal for “Remote Transfer” to Bypass operation.
This function allows a contact closure from a BAS, between terminals TB1-4 and TB1-9, to transfer motor operation from
Drive mode to Bypass mode. This remote transfer to Bypass function overrides the Drive Select manual button. An open
contact causes operation in Drive mode and a closed contact results in Bypass mode.
Smoke Purge Operation
Terminal TB1-5 on the Control PCB A2 is a dedicated terminal for “Smoke Purge” operation.
This function allows a contact closure between terminals TB1-5 and TB1-9 to transfer motor operation to Bypass for a
maximum capacity smoke control function. When in smoke purge mode, during emergency fire/smoke situations, the motor
overloads and safety interlock circuit are overridden to shift the priority to protecting people rather than equipment.
[Note: Smoke purge overrides all other control inputs and selector buttons. Smoke purge operation can only be terminated by
opening the contact closure at terminal TB1-5 or by opening the disconnect switch (S1 on schematic E7L-00).]
Multi-Function Digital Inputs
The Bypass 120 VAC logic circuit is interconnected with the Drive multi-function digital input terminals to allow a single
customer interface to control both Drive and Bypass circuits.
As a result, only Drive digital input terminals S6 and S7 are available for other uses. Drive Terminals S6, S7 and SN have been
brought out to TB5-5, TB5-4 and TB5-2 respectively. See Appendix A and Chapter 5, parameter H1-04 and H1-05 for
programming instructions.

Auto Transfer to Bypass
When enabled (DIP switch S2-1 ON), the Bypass unit will automatically switch into Bypass mode on a Drive fault. After
clearing the Drive fault condition, the function resets by moving the disconnect switch to the OFF position and waiting for the
keypad to go blank. CAUTION: Before selecting this function in fan applications, care must be taken to ensure that the
ductwork is designed to handle the pressure resulting from full speed operation with the VAV terminal unit dampers at
minimum position or closed. The factory default for this function is disabled.
Power Up Mode
The Drive/Bypass electronic interface can be configured (via a DIP switch) to be in the AUTO mode or OFF when power is
applied to the unit. This function is controlled by DIP switch S2-2, ON for AUTO operation on power up. The factory default
is to power up to the OFF mode.

In order to provide you with the most reliable Drive and Bypass unit available, and to avoid any extra costs related to loss or
reduction of warranty coverage, an authorized Yaskawa service representative should complete this start up procedure. Please
complete the checklist in this document and maintain it in a secured location. Should you have a need to contact Yaskawa in
the future, technical service personnel may request information from this document.
CAUTION
Procedures within this document assume that start up is being accomplished by a Yaskawa authorized service person who has
training on the product and is capable of working through the detailed steps with power applied to the Bypass unit while the
enclosure door is open.

Drive Model Number: ______________________Drive Serial Number: _________________________________
In this Start-Up chapter, when referring to the keypad display, the complete description of the parameter setting choices are
presented for clarity purposes. For example, one of the setting choices for parameter b1-02 is “1: terminals.” Keep in mind that
on the standard LED keypad display, only the number of the choice will be shown. The optional LCD keypad display is
required to see the complete description.
IMPORTANT INFORMATION
The Safety Interlock Circuit at Power Up
On power up the E7L will display a red “Safety Open” LED in the “System Status” area of the front control panel if a normally
closed “Safety Circuit” has not been installed between TB1-1 and TB1-9 on PCB A2. This condition will prevent Drive or
Bypass operation.
One of the following three items needs to be done prior to start-up:
1)Install an NC “Safety Circuit” between TB1-1 and TB1-9 on PCB A2.
2)Install a jumper between TB1-1 and TB1-9 on PCB A2. This method should be used if a “Safety Circuit” will be added
later in the installation.
3)De-activate these terminals by moving DIP switch S2-7 to the ON position (toward the enclosure door). This solution is
only suggested if a “Safety Circuit” will
never be applied to the drive system.
Start Up and Operation 4 - 2
The BAS Interlock Circuit at Power Up
When a Run command is received in HAND or AUTO mode, the E7L will display a red “Damper/Bas” LED in the “System
Status” area of the front control panel. This condition will prevent Drive or Bypass operation.
One of the following three items needs to be done prior to start-up:
1)Install a “BAS Interlock Circuit” between TB1-3 and TB1-9 on PCB A2.
2)Install a jumper between TB1-3 and TB1-9 on PCB A2. This method should be used if a “BAS Interlock Circuit” will be
added later in the installation.
3)De-activate these terminals by moving DIP switch S2-8 to the ON position (toward the enclosure door). This solution is
only suggested if a “Safety Circuit” will
never be applied to the drive system.
Start Up and Operation 4 - 3
BYPASS UNIT START UP PREPARATION
Note: These instructions assume that all jumpers and DIP switches are in the factory default position as defined by schematic
diagram E7L-00.
1. Review this Bypass Technical Manual and any option instructions and schematics shipped with the Drive and Bypass
unit.
2. Verify that the model numbers and voltage ratings are as specified in the purchase order by matching the nameplate
data for each unit to the purchase order.
3. Verify that the unit has been installed in accordance with Chapter 1, Receiving and Mechanical Installation and
Chapter 2, Electrical Installation.
4. Inspect the security of the supply line power, ground connections and all control circuit connections as identified in
Chapter 2, Electrical Installation.
Double check all the power wires and motor wires.
Verify that the electrical supply power lines (L1, L2, L3) are connected to the input disconnect switch (S1 on the wiring diagram in Chapter 2) and that the motor leads (T1, T2, T3) are connected to the output terminals of the overload
relay (S10 on the wiring diagram in Chapter 2). Ensure that all connections are
cause intermittent problems or overheating. Factory connections sometimes come loose during shipment.
tight, loose wire connections may
5. Review the installer’s “as wired” schematic. Determine if a driven motor “safety circuit” is connected. This is a series
circuit of NC contacts from devices such as a smoke/fire sensor, freeze-up thermostat or high static pressure limit
switch. Verify that these customer emergency contacts are properly terminated in the Bypass safety shutdown circuit.
These contacts should be wired between terminal TB1-1 and TB1-9. No field programming is required.
Verify that all other field installed wires are correctly terminated (included the shields).
6. Verify that the motor is wired for the application voltage. Record the motor nameplate information:
Voltage ______________________________Motor Rated Amps ___________________________________
7. Verify that the input voltage matches the Bypass unit rating.
8. Verify that the motor rated full load amps (FLA) does not exceed the rated output current of the Drive and Bypass
controlling it. When multiple motors are simulaneously operated by the Drive, the sum of all motor FLA values must
be less than or equal to that of the Drive and Bypass controlling them.
9. Record any other connections to the Bypass unit, by terminal number to determine if special programming of any of
the following is required. (see Chapter 5 or TM.E7.02 for programming details).
•Multi-function Digital Inputs
•Multi-function Digital Outputs
•Analog Outputs
•Differential PI control
10. Verify that the building automation system logic is ready for the start, stop and speed command functions.
Start Up and Operation 4 - 4
BYPASS UNIT START UP PROCEDURE
(Please review “Bypass Start Up Preparation” on page 4-4)
The front control panel has a digital alpha/numeric display and keypad, in the upper portion, for Drive operation and programming. The row of LEDs above the alpha/numeric display indicate Drive operational status. The REMOTE SEQ and REF
LEDs in this row are always lit in most Bypass unit applications of the E7 Drive (See Chapter 3 for an explanation). The row
of LEDs below the alpha/numeric display indicate the Drive menu that is presently active.
The lower portion of the front control panel displays the operating mode status via LEDs and controls the HAND/OFF/AUTO
functions for both the Drive and Bypass. The general rule for LED colors, in the lower portion of the control panel, is:
Green = Normal Status
Amber = Abnormal Status
Red = Fault Status
1. Before applying power, make sure that the following conditions are met:
•The VAV terminal unit dampers, in supply fan applications, are open to prevent duct flexing or damage in a full
speed, across the line starting situation.
•The electro-mechanical motor OverLoad Relay (OLR) (S10) is adjusted to equal the Full Load Amps (FLA) value
from the motor nameplate.
The OLR is mounted to the contactor assembly or back panel (depending on rating), just above the Bypass contactor.
See Figure 4.1. Electrically on the output power side of the Bypass unit, the adjustable thermal OLR provides overload
protection for the motor in both the Drive and Bypass operating modes. The OLR is set up in the factory to be a
manual reset device, requiring operator attention if an overload trip-out is experienced.

IMPORTANT
To maintain overcurrent, short-circuit, and ground-fault protection, the manufacturer’s instructions for
setting the motor OLR must be followed.
2. Apply power to the Drive and Bypass package. Using a VOM, ensure that all three phases are present and that the
input voltage is correct for the system being set up. When power is applied to the E7L unit, the control logic will
briefly (<3 seconds) self test all the control panel operating mode LEDs, located on the lower half of the control panel.
Then, the SEQ and REF LEDs (red), DRIVE menu LED (red), STOP LED (red), Control Power LED (green), Ready LED (green), Drive Select LED (green) and OFF LED (amber) will be lit when the Drive and Bypass are
ready for operation. The alpha/numeric display will show input frequency (speed command), at power up. [Note: If
the Motor O/L LED (red) is lit, press the reset button on the motor overload relay.]
3. Various menus are directly available by pressing the MENU key (see Chapter 3). When in the DRIVE menu, the
Drive can accept a run command from local (Hand mode) or remote (Auto mode) sources. Press the MENU
key until the ADV/PRGM menu LED (red) is lit. From here, any of the E7 parameters can be accessed and
changed using the ,, and DATA/ENTER keys. See Appendix A for a list of programmable features. The VERIFY menu can be used to review or modify only those parameters that have been changed from the Drive’s
default values. Using the
,, and DATA/ENTER keys as needed, verify that the parameters are correct for the
Drive and installation conditions. See the Factory Parameter Settings printed in Table 1 and Table 6 on page 2 and 3
of the E7L-00 Schematic Diagram or Chapter 5 (Table 5.1 and 5.2) of this manual. Consider any additional parameter
settings that may be needed by this specific application.
The Factory Parameter Settings, table 1 of E7L-00, documents E7 Drive parameter settings, required to interface
with the Bypass logic circuit, that have been established at the factory and stored in a dedicated location in the E7
memory as “User Initialization” values (think of it as a “back-up file”). If additional parameters are set to the
specific needs of the application project,
and the system operation has been checked and verified, then the “User
Initialization” values should be stored in memory again by entering “1: Set Default” in parameter o2-03.
When there is a need for re-initialization (resetting to a known factory starting point for troubleshooting
purposes) of the E7L Drive, then a 2-wire initialization should be carried out by entering “2220: 2 Wire Initial”
in parameter A1-03, followed by entering the “1110: User Initialize” function, also in parameter A1-03. This will
re-establish the E7 Drive set-up required for the E7L Bypass application and any “user” parameter values that
have been stored.
Start Up and Operation 4 - 6
Table 1 is also used to document parameters that have been factory set to typical values for fan and pump
applications. These parameters [b1-07, b1-08, b8-01, L4-05, L5-01, L5-03, o1-02, o2-03 and o3-02] may be
changed to meet the needs of the specific application.
4. From the ADV/PRGM menu, press DATA/ENTER, go to parameter E1-01 and enter the nominal input voltage that
the Drive will receive in this specific application. The overall voltage classification of the Drive cannot be changed by
this parameter. However, the input voltage should be adjusted within the range available for the given voltage “class”
of the Drive to match the input voltage level normally found on the jobsite. For example, 480 VAC class Drives may
be employed on nominal three phase voltage distribution systems of: 380, 400, 415, 440, 460 or 480 VAC. The factory
default values may need to be changed to meet the needs of the application distribution voltage.
5. From parameter E1-01, use the ESC, and DATA/ENTER keys as necessary, to go to parameter E2-01 and enter
the Motor Rated Current. Set this parameter to the motor rated Full Load Amps (FLA) shown on the motor nameplate.
This is essential for proper Drive operation and motor overload protection. [Note: Do not include the “service factor”
amps.]
6. Press the MENU key to return to the DRIVE menu and the same operational status LED configuration described in
step 2 above. The alpha/numeric display will now be the speed command frequency.
To start the motor in Drive mode, press the HAND key. The DRIVE Run LEDs (red and green) and the HAND LED
(amber) will light and the Drive output will ramp up to “6 HZ.” Verify that motor rotation is correct.
If the direction of motor rotation is wrong, press the OFF key and turn the Power OFF! Wait for the red CHARGE
LED (near the Drive power terminals) to go out. When it does, swap the wires for T1 & T2 on the output terminals
of the motor Overload Relay. Tighten the terminal lugs, reapply the power, press the HAND key and re-check the
rotation direction.
7. With correct motor rotation, press the MENU key, if necessary, to return to the DRIVE menu. Press DATA/ENTER
(as needed to get “F” flashing) then using the
range, while observing operation. If excessive vibration of the driven load is noted at specific frequencies (speeds), the
Jump Frequency function may be used to eliminate this vibration, by programming d3-01 through d3-04. Press the
OFF key.
8. Determine whether the remote speed command is a 0-10 VDC or a 4-20 mA signal. The positive side of the signal
should be connected to terminal TB3-3 of the E7L terminal strip. The “common” of the remote speed command
signal should be connected to terminal TB3-1 of the E7L. See the connection diagram on page 1 of the E7L Bypass
unit schematic E7L-00 (or Chapter 5 in this manual). [Note: The factory default is 4-20 mA, to change to 0 to 10 VDC
adjust parameter H3-08 to “0: 0-10VDC” and move E7L DIP switch S1-2, on the terminal PCB to the OFF
position (toward the unit rear).]
9. For the Auto mode, request a run command and speed command signal from the building automation system to
confirm remote (auto) operation.
10. Press the AUTO key, the DRIVE Run LEDs (red and green), the AUTO LED (green) and AUTO Run LED (green)
will light and the Drive output will ramp up to the Auto mode speed command. Observe if the remote speed command
can achieve the minimum and maximum speeds desired. If not, perform the following: - See Chapter 5.
For 0-10 VDC input at Terminal TB3-3
1. With no input, adjust the Bias (H3-11 setting) until an output of “0.0 Hz” is obtained.
2. With full scale input, adjust the Gain (H3-10 setting) until an output of “60.0 Hz” (or other desired maximum
frequency) is obtained.
and keys, manually run the Drive throughout its entire speed
For 4-20 mA input at Terminal TB3-3
1. With 4 mA input, adjust Bias (H3-11 setting) until an output of “0.0 Hz” is obtained.
2. With 20 mA input, adjust Gain (H3-10 setting) until an output of “60.0 Hz” (or other desired maximum
frequency) is obtained.
Start Up and Operation 4 - 7
11. If the circuit breaker option is not present - go to step 12.
In preparation for testing the Bypass, observe the trip setting of the Circuit Breaker. The trip point is factory set at the
lowest possible setting and must be adjusted for each application. This breaker will trip due to inrush current and load
inertia unless it is reset!
•For fan applications adjust the trip setting to ten times motor FLA.
•For pump applications adjust the trip setting to six times motor FLA.
If Circuit Breaker tripping is experienced at these settings during motor starting on Bypass, increase the setting
gradually until the motor can be started without Circuit Breaker tripping.
12. Press the OFF key and press the BYPASSSelect key. The Drive will ramp the motor to zero speed, then the control
will be transferred to Bypass mode. Be prepared to monitor the rotation direction of the motor in Bypass operation.
“Bump” the HAND key and quickly press the OFF key. Check the motor rotation.
operating in Bypass mode until rotation is correct!
If the rotation direction in Bypass is correct, skip the rest of this step. If not, carry out the following corrections:
1.Turn OFF the incoming power feed to the E7L unit. Since the correct rotation in Drive mode was previously
established, do not change any output wires at the motor.
2.Instead, verify that power is OFF. Then swap the wires for L1 & L2 on the input side of the Disconnect Switch or
Circuit Breaker. This will effect rotation in Bypass operation only. Once connections are complete and tight,
reapply the incoming power and repeat the previous step to re-check the rotation direction in Bypass mode.
13. Run the motor in Bypass by pressing the HAND key. Record all the phase voltages and currents at this time.
14. Press the OFF key and press the DRIVE Select key. Press the HAND key and press the DATA/ENTER key, then
scroll the Speed Command to “60 HZ” operation. Monitor the voltages and currents in each of the output phases at full
speed to make sure that the voltages are balanced and that the currents are within the motor nameplate rating during
accel, stable speed, and decel.
Do not allow the motor to continue
15. If this application requires the Drive to operate in PI mode, see Chapter 5.
For serial communication, refer to Appendix D in this manual or TM.E7.21 (APOGEE FLN) and TM.E7.22 (Metasys N2).
(For selector key positions, control inputs and DIP switch selectable functions.)
The Bypass has two modes of operation: Bypass and Drive. When in the Bypass mode the connected motor is run directly
from the incoming AC line, whereas in Drive mode the motor is run from the Drive output. The DRIVE Select and Bypass
Select keys located on the front panel determine the operating mode. Within each operating mode are two methods of control;
HAND and AUTO. The HAND/OFF/AUTO selector keys on the front panel determine this control method.
Table 4.1 provides a look at various combinations of the control panel selector key positions, control inputs to TB1 through
TB5 and the status of the DIP switch selectable functions.
For additional influences on the Drive behavior in Drive operating mode, consult Table 5.1 and Table 5.2. These tables explain
the settings of Drive parameters required by the Bypass logic (Table 5.1) and those that are also dependent upon the control
options present on the unit (Table 5.2). For Example: In the second line of Table 5.2, for a Bypass equipped with no options
and DIP switch S1-2 in the off position, the hand mode speed command is based on the setting of d1-02 and the auto mode
speed command signal is 0-10VDC.
Selector Key Functions
Operating with HAND selected - Drive mode:
The Drive can be operated locally from the control panel by first pressing the DRIVE Select key. Then pressing the HAND key gives the front panel control of the Drive operation. Pressing HAND also provides the run command to the
Drive. When placed into HAND mode the Drive begins running at the HAND mode speed command.
Operating with AUTO selected - Drive mode:
The Drive can be operated remotely by pressing the DRIVE Select key. Then pressing the AUTO key gives a remote
device (BAS or DDC) control of the Drive. In the AUTO mode the Drive will look for a run command contact closure at
terminals TB1-2 and TB1-9 on PCB A2. Speed command signal level and source is determined by the parameter settings
and the options present in the unit, see Tables 5.1 and 5.2. The AUTO speed command is wired to terminals TB3-3 and TB3-1. Consult Figures 2.7 and 2.8 in Chapter 2, Electrical Installation for correct configuration of the speed command
(analog frequency reference).
Operating with HAND selected - Bypass mode:
The Bypass can be operated locally from the front control panel by pressing the Bypass Select key. In BYPASS mode the
Bypass contactor coil can be energized manually by pressing the HAND key. In Bypass mode, selecting HAND operation
causes the motor to run at full speed, directly “across the line”.
Operating with AUTO selected - Bypass mode:
The Bypass can be operated remotely by pressing the Bypass Select key and selecting AUTO operation. In the AUTO
mode the Bypass will look for a run command contact closure at terminals TB1-2 and TB1-9 on PCB A2, to control the
run/stop status of “across the line” full speed motor operation.
Operating with DRIVE TEST selected - Bypass mode:
The only valid use of the DRIVE TEST function is in Bypass mode. DRIVE TEST provides for local control of the
Drive for programming or other “tests” while keeping it isolated from the motor that is operating in Bypass mode.
DIP Switch Selectable Functions
The switch selectable functions, Auto Transfer, Safety Circuit Interlock and BAS Interlock represent control strategies that
may need to be disabled under various application circumstances. They may be enabled in any combination from none of them
to all of them. See Table 4.1 for a summary of some common combinations of these switch selectable inputs.
Auto Transfer to Bypass
When enabled (DIP switch S2-1), the Bypass unit will automatically switch into Bypass mode on a Drive fault. After clearing
the Drive fault condition, the function resets by moving the disconnect switch to the OFF position and waiting for the keypad
to go blank. CAUTION: Before selecting this function in fan applications, care must be taken to ensure that the ductwork is
designed to handle the pressure resulting from full speed operation with the VAV terminal unit dampers at minimum position
or closed. The factory default for this function is disabled.
Start Up and Operation 4 - 12
Safety Interlock Circuit
A Control terminal block position (TB1-1) is provided to connect the series circuit of Normally Closed (NC) safety
devices such as: freeze-up thermostats, smoke/fire sensors, high pressure limits, temperature limits or vibration detectors.
Anytime all the safety device contacts are closed, the Drive or Bypass will operate. When any one of these contacts open,
the Drive or Bypass will immediately stop operating. This input is momentary, when a safety device contact re-closes, the
Drive or Bypass will return to operation.
On power up the E7L will display a red “Safety Open” LED in the “System Status” area of the front control panel if a
normally closed “Safety Circuit” has not been installed between TB1-1 and TB1-9 on PCB A2. This condition will
prevent Drive or Bypass operation.
One of the following three items needs to be done prior to start-up:
1) Install a NC “Safety Circuit” between TB1-1 and TB1-9 on PCB A2.
2) Install a jumper between TB1-1 and TB1-9 on PCB A2. This method should be used if a “Safety Circuit” will be
added later in the installation.
3) De-activate these terminals by moving DIP switch S2-7 to the ON position (toward the enclosure door). This solution
is only suggested if a “Safety Circuit” will
never be applied to the drive system.
Building Automation System Interlock Circuit
This is a Drive and Bypass enable input. A control terminal block position (TB1-3) is provided to connect Normally Open
(NO) enabling contacts such as: damper end switches or occupied cycle timers. An open contact will override the run com
mand, preventing Drive or Bypass operation until these input contacts are closed. For example, this input could insure that the
system dampers achieve an operating position before the fan is started in order to protect the ductwork from over pressure.
-
When a Run command is received in HAND or AUTO mode, the E7L will display a red “Damper/BAS” LED in the
“System Status” area of the front control panel. This condition will prevent Drive or Bypass operation.
One of the following three items needs to be done prior to start-up:
1) Install a “BAS Interlock Circuit” between TB1-3 and TB1-9 on PCB A2.
2) Install a jumper between TB1-3 and TB1-9 on PCB A2. This method should be used if a “BAS Interlock Circuit” will
be added later in the installation.
3) De-activate these terminals by moving DIP switch S2-8 to the ON position (toward the enclosure door). This solution
is only suggested if a “Safety Circuit” will
never be applied to the drive system.
Start Up and Operation 4 - 13
Contact Closure Inputs
Auto Mode Run/Stop Contact Input
TB1-2 and TB1-9 are input terminals used for the Run/Stop command when in the AUTO mode. When these input contacts
close, the unit will begin running. When the contacts reopen, the unit will cease
running.
Remote Transfer to Bypass
This function allows a contact closure from a BAS, between terminals TB1-4 and TB1-9, to transfer motor operation from
Drive mode to Bypass mode. This remote transfer to Bypass function overrides the DRIVE/BYPASS selector keys. An open
contact causes operation in Drive mode and a closed contact results in Bypass mode.
Smoke Purge
This function allows a contact closure between terminals TB1-5 and TB1-9 to transfer motor operation to Bypass for a maximum capacity smoke control function. When in smoke purge mode,
situations, the motor overloads and safety interlock circuit are overridden to shift the priority
equipment. [Note: Smoke purge overrides all other control inputs and selector switches. Smoke purge operation can only be
terminated by opening the contact closure at terminals TB1-5 and TB1-9 or by opening the Disconnect Switch.]

Programming
This Manual contains descriptions of all parameters in the Drive that may be useful in
Bypass applications. Parameters are listed in alpha-numerical order. Parameter number
and name, along with a detailed description and its settings are described on the following
pages. For descriptions of all drive parameters, see the Programming Manual (TM.E7.02).
Standard LED Keypad Display and Optional LCD Keypad Display:
This programming chapter has been written to cover both the standard LED keypad display and the optional LCD keypad
display. When referring to the keypad display, the complete description of the parameter setting choices are presented for
clarity purposes. For example, one of the setting choices for parameter b1-02 is “1: terminals.” Keep in mind that for the
standard LED keypad display, only the number of the choice will be shown. The optional LCD keypad display is required to
see the complete description.
Some sections of this chapter will apply only to the optional LCD operator, for example:
A1-00 Language Selection
o1-05 to o1-08 LCD Display Selections
Programming Instructions for Individual Drive Parameters:
The discussions of individual Drive parameters in Chapter 5 are descriptive of the basic E7L unit without any options that
would effect the programming of the E7 Drive.
Programming for Various Configuration and Options:
Tables 5.1 and 5.2 and the section titled “Discussion of Table 5.2 Option-Dependent Bypass Parameter Settings” provide
details of the unique programming required for the E7L Bypass applications of the Drive with various configurations of
options and sources for the control signals.
Tables 5.3 and 5.4 are similar but add PI control to the configuration possibilities.
Virtual Terminals
The Drive multi-function digital inputs and Drive analog inputs have (for the most part) become “virtual terminals” in the E7L
two contactor Bypass design.
The Bypass 120 VAC logic circuit is interconnected, via ribbon cable, with the Drive multi-function digital inputs and Drive
analog inputs to allow a single set of customer interface terminals to control both the Drive and Bypass circuits.
The Drive firmware however refers to these Drive terminals in order to program the functions of these inputs. The E7L
programming documentation and this manual then need to refer to these “virtual terminals” in Chapter 5 (programming) and
Appendix A (parameters). These “virtual terminals” are called out, for example, in Table 5.1 Bypass Parameter Settings.
Drive terminals S1 through and including S5 are consumed by the needs of the bypass logic circuit. The programming of these
terminal functions is essential to the operation of the Drive and Bypass unit and is described in Tables 5.1 and 5.2.

Bypass Unit Basic Programming Parameters
The basic Drive programming for a Bypass unit is different from that of a Drive installation without the Bypass option.
Several Drive parameters have been programmed at the factory to meet the needs of the Bypass logic circuit. See Table 5.1
below, the highlighted parameters are required by the Bypass logic circuit. Only those parameters that are changed from the
Drive default are listed.

The shaded Bypass Parameter Settings in Table 5.1 document Drive parameter settings, required to interface with the Bypass
logic circuit, that have been established at the factory and stored in a dedicated location in the memory as “User Initialization”
values (think of it as a “back-up file”).
Table 5.1 is also used to document parameters that have been factory set, for convenience, to typical values for fan and pump
applications. These parameters may be changed to meet the needs of the specific application.
If additional parameters are set to the specific needs of the application project, and the system operation has been checked and
verified, then the “User Initialization” values should be stored in memory again by selecting and entering “1: Set Default” in
parameter o2-03.
When there is a need for re-initialization of the “user” parameters (re-setting to the “User Initialization” values) of the Bypass
unit, then a “User Initialization” function should be carried out by selecting “1110: User Initialize” in parameter A1-03. This will
re-establish the drive set-up required for the Bypass application and any “user” parameter values that have been stored.
The factory parameter settings required to interface with the bypass logic circuit have also been stored in the digital keypad
memory. If there is a need for re-initialization (re-setting to a known factory starting point for trouble-shooting purposes) of the
Bypass unit, then the “back-up file” in the digital keypad memory can be copied to the drive. In parameter o3-01 select
“2: OP->INV WRITE” to carry out the copy function.

Notes:
See Appendix D, Communications, for additional information on serial communication.
Hand mode run/stop for Drive and Bypass is always via the front control panel HAND selector key.
The HAND/OFF/AUTO selector keys must be in AUTO position if serial communication is to be used to control the
