Safety Warning

Serious injury may possibly occur due to loss of required safety functions.
When building the system, observe the following warnings to ensure the integrity of the safety-related components.

Setting Up a Risk Assessment System

The process of selecting these products should include the development and execution of a risk assessment system early in the design development stage to help identify potential dangers in your equipment and optimize safety component selection.

  • ISO 12100 General Principles for Design - Risk Assessment and Risk Reduction

Protective Measure

When developing a safety system for the equipment and devices that use safety components, make every effort to understand and conform to the entire series of international and industry standards available, such as the examples given below.

  • ISO 12100 General Principles for Design - Risk Assessment and Risk Reduction
  • IEC 60204-1 Electrical Equipment of Machines - Part 1: General Requirements
  • ISO 13849-1, -2 Safety-related Parts of Control Systems
  • ISO 14119 Interlocking Devices Associated with Guards - Principles for Design and Selection
  • IEC 62046 Application of Protective Equipment to Detect the Presence of Persons

Role of Safety Components

Safety Components incorporate standardized safety functions and mechanisms, but the benefits of these functions and mechanisms are designed to attain their full potential only within properly designed safety-related systems. Make sure you fully understand all functions and mechanisms, and use that understanding to develop systems that will ensure optimal usage.

  • ISO 14119 Interlocking Devices Associated with Guards - Principles for Design and Selection
  • ISO 13857 Safety Distances to Prevent Hazard Zones being Reached by Upper and Lower Limbs

Installing Safety Components

Qualified engineers must develop your safety-related system and install safety components in devices and equipment. Prior to machine commissioning verify through testing that the safety components works as expected.

  • ISO 12100 General Principles for Design - Risk Assessment and Risk Reduction
  • IEC 60204-1 Electrical Equipment of Machines - Part 1: General Requirements
  • ISO 13849-1, -2 Safety-related Parts of Control Systems
  • ISO 14119 Interlocking Devices Associated with Guards - Principles for Design and Selection

Observing Laws and Regulations

Safety Components must conform to pertinent laws, regulations, and standards. Make sure that they are installed and used in accordance with the laws, regulations, and standards of the country where the devices and equipment incorporating these products are distributed.

Observing Usage Precautions

Carefully read the specifications and precautions as well as all items in the Instruction Manual for your safety component to learn appropriate usage procedures. Any deviation from instructions will lead to unexpected device or equipment failure not anticipated by the safety-related system.

Transferring Devices and Equipment

When transferring devices and equipment, be sure to retain one copy of the Instruction Manual and supply another copy with the device or equipment so the person receiving it will have no problems with operation and maintenance.
