Safety Information

Important Information

NOTICE

Read these instructions carefully, and look at the equipment to become familiar with the device before trying to install, operate, service, or maintain it. The following special messages may appear throughout this documentation or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure.

PLEASE NOTE

Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.

A qualified person is one who has skills and knowledge related to the construction and operation of electrical equipment and its installation, and has received safety training to recognize and avoid the hazards involved.

BEFORE YOU BEGIN

Do not use this product on machinery lacking effective point-of-operation guarding. Lack of effective pointof-operation guarding on a machine can result in serious injury to the operator of that machine.

1672609EN-03 01/2020 5

WARNING

UNGUARDED EQUIPMENT

 Do not use this software and related automation equipment on equipment which does not have point-

of-operation protection.

 Do not reach into machinery during operation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

This automation equipment and related software is used to control a variety of industrial processes. The type or model of automation equipment suitable for each application will vary depending on factors such as the control function required, degree of protection required, production methods, unusual conditions, government regulations, etc. In some applications, more than one processor may be required, as when backup redundancy is needed.

Only you, the user, machine builder or system integrator can be aware of all the conditions and factors present during setup, operation, and maintenance of the machine and, therefore, can determine the automation equipment and the related safeties and interlocks which can be properly used. When selecting automation and control equipment and related software for a particular application, you should refer to the applicable local and national standards and regulations. The National Safety Council's Accident Prevention Manual (nationally recognized in the United States of America) also provides much useful information.

In some applications, such as packaging machinery, additional operator protection such as point-ofoperation guarding must be provided. This is necessary if the operator's hands and other parts of the body are free to enter the pinch points or other hazardous areas and serious injury can occur. Software products alone cannot protect an operator from injury. For this reason the software cannot be substituted for or take the place of point-of-operation protection.

Ensure that appropriate safeties and mechanical/electrical interlocks related to point-of-operation protection have been installed and are operational before placing the equipment into service. All interlocks and safeties related to point-of-operation protection must be coordinated with the related automation equipment and software programming.

NOTE: Coordination of safeties and mechanical/electrical interlocks for point-of-operation protection is outside the scope of the Function Block Library, System User Guide, or other implementation referenced in this documentation.

START-UP AND TEST

Before using electrical control and automation equipment for regular operation after installation, the system should be given a start-up test by qualified personnel to verify correct operation of the equipment. It is important that arrangements for such a check be made and that enough time is allowed to perform complete and satisfactory testing.

Follow all start-up tests recommended in the equipment documentation. Store all equipment documentation for future references.

Software testing must be done in both simulated and real environments.

Verify that the completed system is free from all short circuits and temporary grounds that are not installed according to local regulations (according to the National Electrical Code in the U.S.A, for instance). If highpotential voltage testing is necessary, follow recommendations in equipment documentation to prevent accidental equipment damage.

Before energizing equipment:

 Remove tools, meters, and debris from equipment.  Close the equipment enclosure door.

WARNING

EQUIPMENT OPERATION HAZARD

 Verify that all installation and set up procedures have been completed.  Before operational tests are performed, remove all blocks or other temporary holding means used for

shipment from all component devices.

 Remove tools, meters, and debris from equipment.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

6 1672609EN-03 01/2020

 Remove all temporary grounds from incoming power lines.  Perform all start-up tests recommended by the manufacturer.

OPERATION AND ADJUSTMENTS

The following precautions are from the NEMA Standards Publication ICS 7.1-1995 (English version prevails):

 Regardless of the care exercised in the design and manufacture of equipment or in the selection and

ratings of components, there are hazards that can be encountered if such equipment is improperly operated.

 It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe

operation. Always use the manufacturer’s instructions as a guide for functional adjustments. Personnel who have access to these adjustments should be familiar with the equipment manufacturer’s instructions and the machinery used with the electrical equipment.

 Only those operational adjustments actually required by the operator should be accessible to the

operator. Access to other controls should be restricted to prevent unauthorized changes in operating characteristics.

Introduction

Presentation

Aim of the TeSys DFB Library

The TeSys DFB library has been developed to simplify and optimize the integration of TeSys U startercontrollers and TeSys T motor management systems in PLC applications, for both PLC programmers and end users.

The TeSys DFB library for Unity Pro can be ordered with part number UNYLTSZFUWB.

Advantages for the PLC Programmer

The TeSys DFB library enables the PLC programmer to

 simplify the program design: the program is split by functions (control, command, data treatment,...),  optimize the programming time: the DFB is tested and can be re-used for different applications,  increase the program understanding: the applications are coded in the same way using the common

DFB,

 optimize the program size: the same code is used for each DFB instantiation,  simplify the TeSys U and TeSys T integration: the data mapping management is masked.

Advantages for the End User

The TeSys DFB library enables the end user to

 optimize the communication response time:

 the Modbus requests management is optimized,  the data exchange management is optimized,  the product performance is taken into account,

 have a functional view of the motor-starter by providing direct access to common functions (Ready,

Alarm, Run, Stop,...),

 group data related to a specific application (diagnostic, maintenance, measurement,...) through a

program number,

 facilitate debugging: variables used by the DFB are identified on its interface.

PLC Platform Compatibility

The TeSys DFB library can be integrated in the Unity Pro programming platform with Quantum, Premium and M340 PLC platforms.

TeSys Compatibility

The TeSys DFB library for Unity Pro is compatible with:

 TeSys U starter-controllers (up to 38 A/18.5 kW or 25 hp),  TeSys T motor management system.

Communication Protocol Compatibility

The following table describes the TeSys DFB library compatibility with communication protocols and the corresponding TeSys U and TeSys T assemblies.

TeSys DFB Sequencing

Introduction

Some of the TeSys DFBs use a sequencing system using dedicated inputs and outputs that enable the sequencing and the synchronization of the treatment between DFBs.

The following derived function blocks use a sequencing system:

 Ctrl_cmd_mdb_u_••••  Ctrl_cmd_mdb_t_••••  Special_mdb_u_••••  Special_mdb_t_••••  Custom_mdb_••••  Special_pkw_u  Special_pkw_t  Custom_pkw  Timestamp_•

Sequencing System Principle

The sequencer has 2 boolean inputs and 3 boolean outputs:

Introduction

 The _cmd suffix indicates a command dedicated to the DFB sequencer function.  The _st suffix indicates a status information concerning the DFB sequencer function.

The following table describes the sequencer inputs and outputs:

Input/Output Description

Rst_cmd This command resets the DFB and/or restarts the DFB treatment if Strt_cmd is set to 1.

Strt_cmd This command starts the DFB treatment.
