Safety Light Curtain

F3SL Series

Cat. No. SCEE712-E2-1

Introduction

Thank you for purchasing the F3SL Series Safety Light Curtain. Always heed the following points when using the F3SL:

• Make sure that personnel operating the F3SL are knowledgeable about the machine on which it is installed

• Read this manual completely and be sure you understand the information provided before attempting to operate the F3SL

• Keep the manual in a secure and convenient location and refer to it as necessary.

(1) The F3SL has not received the type approval provided by Article 44-2 of the Industrial Safety and Health

Law of Japan. Therefore, it cannot be used in Japan as a safety device for pressing or shearing machines provided by article 42 of that law.

(2) F3SL an equipment conforming to ESPE (Electro Sensitive Protective Equipment) specified in the 1st

Clause of Safety Component, Annex IV B in the EU (European Union) Machinery Directive. F3SL also conforms to the following overseas regulations and standards.

EU regulations and technical standards:

- Machinery Directive: No. 98/37/EC

- EMC Directive: No. 89/336/EEC

- EN 61496-1(06/98) (Type4 ESPE) IEC standard

- IEC 61496-2(11/97) (Type 4 AOPD)

(3) F3SL has been received the following certification from EU authorized institutions.

"EC Type Approval (TYPE 4 ESPE)" in accordance with the Machinery Directive, from TÜV Rheinland.

If you use the F3SL under the condition or environment shown below, be sure to use it by leaving a margin for each rating and function and taking system safety into consideration.

(1) Use of the F3SL under any condition or environment not described in this manual. (2) Use of the F3SL for devices and facilities requiring special safety (e.g., nuclear control, railway, aerospace,

automobile, combustion facility, medical system, space development, and large-scale amusement machinery).

General conventions for safe use

The following conventions are used for precautionary items in this manual in order to ensure safe and proper use of the F3SL. Items listed here are critical for safety and must be heeded at all times.

Regulations and Standards

Notice

Precaution on Safety

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Indicates prohibited actions.

WARNING

A F3SL should only be installed, checked out and maintained by a qualified person. It is important that the user be familiar with the installation requirements, safe mounting distance, controls and features before using the F3SL.

If the F3SL is used as a safety device, the user has the responsibility to insure that applicable national, federal and local safety rules, codes and regulations are satisfied. In addition, the user should insure that all machine operators, maintenance personnel, electricians, supervisors, etc. are familiar with and understand all instructions regarding the use of the F3SL, the machinery on which it is installed and the appropriate safety regulations.

Perimeter guarding installations must not allow a machine or robot to restart automatically. Use a start switch placed outside and within view of the hazardous area.

Disconnect power before removing end caps.

Use of Exact Channel Select and/or Floating Blanking will make the F3SL system less sensitive to objects in the detection zone. Improper use of either can result in severe injury to personnel. Exact Channel Select may require a hard barrier guard (see “9-2-1 Additional Guarding” on page 9-2-1 Additional Guarding 19), Exact Channel Select or Floating Blanking may require an increase in the safety distance. Read the following section carefully.

Using Exact Channel Select with Floating Blanking is an advanced feature. All situations which may occur to the F3SL system detection zone must be carefully considered. The F3SL system may be less sensitive to objects in the detection zone. The safety distance must be increased. Failure to do so may cause serious injury.

To prevent a hand or other objects to enter the channel-selected part, provide a physical guard such as a fence.

This product is designed for use on a 24 VDC, negative ground (protective earth) electrical system only. Never connect the F3SL to a positive ground (protective earth) system. With a positive ground (protective earth) wiring scheme, certain simultaneous shorts of both safety outputs may not be detected and the guarded machine may not stop resulting is severe operator injury.

Never install a F3SL system without regard to the safety distance. If the F3SL system is mounted too close to the point of operation hazard, the machine may not stop in time to prevent an operator injury.

Install the F3SL system so as not to be affected by the reflection from the reflective surface. Failure to do so may cause the system undetectable, resulting in severe operator injury.

Never use only a single safety output to control the machine. Should this single output fail, the machine may not stop, resulting in severe operator injury. The machine must be connected using both safety outputs.

The tests outlined in the Test Procedure in Appendix B must be performed at installation, according to the employer’s regular inspection program and after any maintenance, tooling change, set up, adjustment, or modification to the F3SL system or the guarded machine. Where a guarded machine is used by multiple operators or shifts, it is suggested that the test procedure be performed at each shift or operation change. Testing ensures that the light curtain and the machine control system work properly to stop the machine. Failure to test properly could result in serious injury to personnel.

1 Important Safety Warnings

A F3SL system is a general purpose presence sensing device designed to guard personnel working around moving machinery.

Whether a specific machine application and F3SL system installation complies with safety regulations depends on the proper application, installation, maintenance and operation of the F3SL system. These items are the responsibility of the purchaser, installer and employer.

The employer is responsible for the selection and training of personnel to properly install, operate, and maintain the machine and its safeguarding systems. A F3SL system should only be installed, verified and maintained by a qualified person.A qualified person is defined as "a person or persons who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge, training or experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work." (ANSI B30.2-1983)

To use a F3SL system the following requirements must be met:

• The guarded machine

must be able to stop anywhere in its cycle. Do not use a safety light curtain on a press

with a full-revolution clutch.

• The guarded machine must not present a hazard from flying parts.

• The guarded machine must have a consistent stopping time and adequate control mechanisms.

• Severe smoke, particulate matter and corrosives may degrade the efficiency of a safety light curtain. Do not use the F3SL system in this type of environment.

• All applicable governmental and local rules, codes, and regulations must be satisfied. This is the employer’s responsibility.

• All safety-related machine control elements must be designed so that a alarm in the control logic or failure of the control circuit does not lead to a failure to danger.

• Additional guarding may be required for access to dangerous areas not covered by the F3SL system.

• Perform the OMRON test procedure at installation and after maintenance, adjustment, repair or modification to the machine controls, tooling, dies or machine, or the F3SL system.

• Perform only the test and repair procedures outlined in this manual.

• Follow all procedures in this manual for proper operation of the F3SL system.

The enforcement of these requirements is beyond the control of OMRON. The employer has the sole responsibility to follow the preceding requirements and any other procedures, conditions and requirements specific to his machinery.

WARNING

Please read this information completely before starting the installation procedure. A F3SL should only be installed, checked out and maintained by a qualified person. It is important that the user be familiar with the installation requirements, safe mounting distance, controls and features before using the F3SL.

2 Theory of Operation

2-1 F3SL System Specifications

The F3SL is a long-range, single-beam infrared safety light curtain designed for machine perimeter guarding from personal access.A “redundant” microprocessor design combined with extensive fault mode and effects analysis provides safe, control reliable operation.

A F3SL system consists of one emitter and one receiver. No interconnecting cables or separate control enclosure are required.
