Warnings and Cautions

This Section provides warnings and cautions pertinent to this product, that if not heeded, may result in personal injury, fatality, or equipment damage. Yaskawa is not responsible for consequences of ignoring these instructions.

WARNING

YASKAWA manufactures component parts that can be used in a wide variety of industrial applications. The selection and application of YASKAWA products remain the responsibility of the equipment designer or end user. YASKAWA accepts no responsibility for the way its products are incorporated into the final system design. Under no circumstances should any YASKAWA product be incorporated into any product or design as the exclusive or sole safety control. Without exception, all controls should be designed to detect faults dynamically and fail safely under all circumstances. All products designed to incorporate a component part manufactured by YASKAWA must be supplied to the end user with appropriate warnings and instructions as to that part’s safe use and operation. Any warnings provided by YASKAWA must be promptly provided to the end user. YASKAWA offers an express warranty only as to the quality of its products in conforming to standards and specifications published in the YASKAWA manual. NO OTHER WARRANTY, EXPRESS OR IMPLIED, IS OFFERED. YASKAWA assumes no liability for any personal injury, property damage, losses, or claims arising from misapplication of its products.

WARNING

Read and understand this manual before installing, operating, or servicing this Drive and Bypass Unit. All warnings, cautions, and instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according to this manual and local codes.

Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is on.

Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below 50 VDC. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm safe level.

Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged by high voltage.

The Drive and Bypass unit is not suitable for circuits capable of delivering more than the specified RMS symmetrical amperes. Install adequate branch short circuit protection per applicable codes. Refer to the specification. Failure to do so may result in equipment damage and/or personal injury.

Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the output of the Drive. These devices may generate peak currents that exceed Drive specifications.

To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxiliary contacts must be properly integrated into the control logic circuit.

YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty. This product must not be modified.

Verify that the rated voltage of the Drive and Bypass unit matches the voltage of the incoming power supply before applying power.

i

WARNING

Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be replaced before operation.

Observe electrostatic discharge procedures when handling circuit cards to prevent ESD damage.

The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, motor, and machine area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive and Bypass unit.

Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

Intended Use

Drives and Bypass Units are intended for installation in electrical systems or machinery.

For use in the European Union, the installation in machinery and systems must conform to the following product standards of the Low Voltage Directive:

EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices EN 60201-1, 1997-12 Machine Safety and Equipping with Electrical Devices

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 Bypass mode.

Control logic provides industry standard Hand/Off/Auto functions and safety circuit interlocks in both drive and Bypass operating 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.

This manual is applicable to E7 Drives defined by model numbers CIMR-E7U_ _ _ _ contained within Bypass units defined by model numbers E7L_ _ _ _.

This manual is subject to change as product improvements occur. The latest version of the manual can be obtained from the Yaskawa website www.drives.com . The date shown on the rear cover is changed when revisions are made. The latest version of Drive software is also shown.

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.

Fig 1.4 E7L Bypass Unit Appearance & E7L Control Panel with Keypad Operator Controls

Keypad Control Panel Operator

In a Bypass unit the Drive keypad control panel operator is mounted flush with the hinged door of the enclosure. The Keypad Control/Operator is equipped with 6 LED illuminated selector keys: Hand, Off, Auto, Drive Select, Bypass Select and Drive Test. The E7L also features 11 other status LED indicators: Control Power, Drive Ready, Drive Run, Drive Fault, Bypass Run, Motor O/L, Safety Open, Damper/BAS Interlock, Smoke Purge, Auto Transfer and Auto Run. The membrane over the Drive keypad is non-removable on these Bypass units (In order to use the keypad copy function on a Bypass unit - order a separate keypad, part number CDR001115).

The Keypad Control/Operator 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 row of LEDs below the alpha/numeric display indicate the Drive menu that is presently active.

The lower portion of the Keypad Control/Operator displays the operating mode status via LEDs and controls the HAND/OFF/ AUTO functions for both the Drive and Bypass via a touchpad. The general rule for LED colors, in the lower portion of the

control panel, is:

Green = Normal Status Amber = Abnormal Status Red = Fault Status

Physical Installation 1 - 10

Input Disconnect Switch

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
