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.

EIO0000002600 09/2017

5

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.

6

BEFORE YOU BEGIN

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

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 pointof-operation 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.

EIO0000002600 09/2017

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.

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.


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 high-potential 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.

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.

Description

This example describes how greenhouse ventilation panes can be managed automatically.

Specifications

The owner of a greenhouse would like to acquire an installation to manage the opening and closing of the ventilation window panes located on the greenhouse roof.

The greenhouse has two window panes to provide ventilation. The opening of these window panes is controlled by a motor and 2 sensors that indicate whether the window panes are open or closed:

16

During the day, the window panes open to ventilate the structure from 12:00 to 15:00, at the time of day when, in principle, the temperature is the highest. However, if the temperature is less than

10 °C, the window panes do not open, or when they are already open, they close.

In addition, the window panes open during the day when the temperature reaches 25 °C. If the temperature falls below 25 °C, the window panes must close again.

Finally, at night, the window panes remain closed regardless of the temperature.

Specifications

A homeowner wants to control access to his residence by an automatic gate equipped with a dual direction (opening and closing) motor.

Program features:



Opening:

Whether the gate is closed or in an intermediate position, the remote control signal

 causes the full opening of the gate. During the opening process, any new action on the remote control stops or restarts the motor.

When the gate is fully open, there is a 4 second time delay before closing can start.

Closing:

During the closing process, if the remote control is activated or if the sensor detects motion, the gate is opened. As long as the sensor is activated (for example, a vehicle stopped in the passage way), the gate remains fully open.

Boiler Control

Specifications

To avoid over-consumption of electricity on boiler start-up, the heating elements are heated progressively, and stopped progressively when the boiler is stopped.

This operating principle is shown by the following timing diagram:

An On (MA) button authorizes the activation of the first heating element ( S1 ). After a time delay T , the second element ( S2 ) starts up. After the same time delay, the third element starts up ( S3 ), then the fourth element ( S4 ) again after time-delay T . An Off (AR) button deactivates S1 . The three other elements are progressively deactivated after time delay T .

Program description:



Inputs: The program includes six TIMER function blocks. The function requires entering the same time delay value T in the six function blocks.



As a result, if you modify one of the function blocks, you must enter the new selection in the six function blocks.

Description

This example describes how greenhouse ventilation panes can be managed automatically.

Specifications

The owner of a greenhouse would like to acquire an installation to manage the opening and closing of the ventilation window panes located on the greenhouse roof.

The greenhouse has two window panes to provide ventilation. The opening of these window panes is controlled by a motor and 2 sensors that indicate whether the window panes are open or closed:

34

During the day, the window panes open to ventilate the structure from 12:00 to 15:00, at the time of day when, in principle, the temperature is the highest. However, if the temperature is less than

10 °C, the window panes do not open, or when they are already open, they close.

In addition, the window panes open during the day when the temperature reaches 25 °C. If the temperature falls below 25 °C, the window panes must close again.







Finally, at night, the window panes remain closed regardless of the temperature.

Program description, 3 time ranges are used:

Range 1: Night, from 21:00 to 07:00

Range 2: Day, from 07:00 to 12:00 and from 15:00 to 21:00

Range 3: Noon, from 12:00 to 15:00

Home Lighting

Specifications

A homeowner would like to install a system capable of controlling the lighting of a stairway and outdoor entrance providing access to the house.

Program features:



Outdoor lighting:

The circuit is activated every year from June 1 st to October 1 st and at night by a twilight switch. A sensor detects any motion and activates the outdoor lighting for 2 minutes.



Indoor lighting:

Two pushbuttons are located in the stairwell; one in the entrance and other at the top of the stairs. Their function is identical.



Time-delayed (30 seconds) lighting is obtained by pressing one of the buttons. The timer can

 be inhibited by renewed action on one of the buttons.

Permanent lighting is activated if one button is pressed for at least 2 seconds. A quick press stops it.

Program description, programming is possible at two levels:



Level 1: Program with FBD and logic functions only.



Level 2: Program with SFC functions in addition to FBD and logic functions.

Specifications

A homeowner wants to control access to his residence by an automatic gate equipped with a dual direction (opening and closing) motor.

Program features:



Opening:

Whether the gate is closed or in an intermediate position, the remote control signal

 causes the full opening of the gate. During the opening process, any new action on the remote control stops or restarts the motor.

When the gate is fully open, there is a 4 second time delay before closing can start.

Closing:

During the closing process, if the remote control is activated or if the sensor detects motion, the gate is opened. As long as the sensor is activated (for example, a vehicle stopped in the passage way), the gate remains fully open.




The T1 timer ( Timer A/C ) is used to switch the motor in the opening direction 0.5 seconds after

 the inhibition of closing. This helps avoid short-circuits and mechanical jerks.

The T2 timer ( Timer A/C ) fulfills two simultaneous functions:



The 4 second triggering delay maintains the gate in the open position before beginning the closing motion.



The 0.2 second triggering delay allows the activation conditions of the AND logic block output to be verified.

The feature of being able to stop the gate opening or closing when the remote control signal is detected is an advantage for this type of application.

The parallel connection to the motor terminals allows the addition of a light signal indicating any movement of the gate.

Boiler Control

Specifications

To avoid overconsumption of electricity on boiler start-up, the heating elements are heated progressively, and stopped progressively when the boiler is stopped.

This operating principle is shown by the following timing diagram:

An On (MA) button authorizes the activation of the first heating element ( S1 ). After a time-delay T , the second element ( S2 ) starts up. After the same time-delay, the third elements starts up ( S3 ), then the fourth element ( S4 ) again after time-delay T . An Off (SR) button deactivates ( S1 ). The three other elements are progressively deactivated after time-delay T .




In principle, time delay T is identical for the activation/deactivation of all the heating elements.

The program includes three TIMER A/C function blocks. The function to perform according to

 the specifications requires entering the same time-delay value in the three function blocks.

As a result, if you modify one of the function blocks, you must enter the new selection in the three TIMER A/C function blocks.
