Rockwell Automation SmartGuard 600 User Information

Brand: Rockwell Automation

Model: SmartGuard 600

Type: User Information

Rockwell Automation SmartGuard 600 is a safety controller that can be used to monitor the state of safety devices, such as limit switches and safety mats. It is designed to be used in safety applications up to Category 4, according to EN954-1.

The SmartGuard 600 has a number of features that make it well-suited for safety applications, including:

Dual dry contacts for each input, which allows for the monitoring of normally open and normally closed contacts.
Test pulse outputs, which can be used to test the integrity of the safety circuit wiring.
Safety output contactors, which can be used to control safety devices, such as brakes and contactors.

Important User Information

Solid state equipment has operational characteristics differing from those of

electromechanical equipment. Safety Guidelines for the Application,

Installation and Maintenance of Solid State Controls (publication SGI-1.1

available from your local Rockwell Automation sales office or online at

http://literature.rockwellautomation.com

) describes some important

differences between solid state equipment and hard-wired electromechanical

devices. Because of this difference, and also because of the wide variety of

uses for solid state equipment, all persons responsible for applying this

equipment must satisfy themselves that each intended application of this

equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for

indirect or consequential damages resulting from the use or application of

this equipment.

The examples and diagrams in this manual are included solely for illustrative

purposes. Because of the many variables and requirements associated with

any particular installation, Rockwell Automation, Inc. cannot assume

responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to

use of information, circuits, equipment, or software described in this manual.

of safety considerations.

WARNING

Identifies information about practices or circumstances that can cause

an explosion in a hazardous environment, which may lead to personal

injury or death, property damage, or economic loss.

IMPORTANT

Identifies information that is critical for successful application and

understanding of the product.

ATTENTION

Identifies information about practices or circumstances that can lead

to personal injury or death, property damage, or economic loss.

Attentions help you identify a hazard, avoid a hazard, and recognize

the consequence.

SHOCK HAZARD

Labels may be on or inside the equipment, for example, a drive or

motor, to alert people that dangerous voltage may be present.

BURN HAZARD

Labels may be on or inside the equipment, for example, a drive or

motor, to alert people that surfaces may reach dangerous

temperatures.

General Safety Information

assessment services.

Description

This application example describes a simple safety system that

monitors a safety gate guarding hazardous machinery. The state of the

gate is monitored by two plunger-style limit switches.

The status of the limit switches is monitored by the SmartGuard 600

safety controller. Two safety output contactors are wired to the

outputs on the SmartGuard 600 controller.

The SmartGuard 600 controller is programmed using RSNetWorx for

DeviceNet software.

Safety Function

The safety components used in this example have dual dry contacts.

Two limit switches are used to monitor the safety gate.

The SmartGuard 600 controller also uses its test pulse outputs (T0, T1,

and so on) to send test pulses over the dual limit switch circuits. This

includes shorts to 24V dc and shorts between channels. The pulse test

feature is configured in RSNetWorx for DeviceNet software.

This example meets the requirements of Category 4, according to

EN954-1.

IMPORTANT

This application example is for advanced users and assumes that you

are trained and experienced in safety system requirements.

ATTENTION

A risk assessment should be performed to make sure all task and

hazard combinations have been identified and addressed. The risk

assessment may require additional circuitry to reduce the risk to a

tolerable level. Safety circuits must take into consideration safety

distance calculations which are not part of the scope of this

document.

4. Configure test pulse outputs for the two limit switches and also

External Device Monitoring (EDM).

The Reset button is used as a standard input, so no test pulse is

required.

5. Select the Local Outputs tab.

6. Configure the safety output contactors as Safety Pulse Test.

7. Click Apply and then OK.

Programming

The Logic Editor, launched from within RSNetWorx for DeviceNet

software, lets you program your application using Function Blocks.

Because this application example uses automatic reset, the external

device monitoring (EDM) function block [2] uses the output of the

safety gate monitoring function block [1] directly as its inputs.

Refer to the SmartGuard 600 Controllers User Manual, publication

1752-UM001

, for details on using the Logic Editor.
