Omron DEVICENET SAFETY - 04-2005 Operation Manual page 10

This is the Operation Manual for the DST1-series Safety I/O Terminals. Heed the following items during sys-
tem construction to ensure that safety-related components are configured in a manner that allows the sys-
tem functions to sufficiently operate.
Risk Assessment
The proper use of the safety device described in this Operation Manual as it relates to installation conditions
and mechanical performance and functions is a prerequisite for its use. When selecting or using this safety
device, risk assessment must be conducted with the aim of identifying potential danger factors in equipment
or facilities in which the safety device is to be applied, during the development stage of the equipment or
facilities. Suitable safety devices must be selected under the guidance of a sufficient risk assessment sys-
tem. An insufficient risk assessment system may lead to the selection of unsuitable safety devices.

ment
Safety Measures
When using this safety device to build systems containing safety-related components for equipment or fa-
cilities, the system must be designed with the full understanding of and conformance to international stan-
dards, such as those listed below, and/or standards in related industries.
• Typical related international standards: ISO/DIS 12100, Safety of Machinery -- Basic Concepts and
General Principles for Design IEC 61508, Safety Standard for Safety Instrumented Systems (Func-
tional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems)
Role of Safety Device
This safety device is provided with safety functions and mechanisms as stipulated in relevant standards, but
suitable designs must be used to allow these functions and mechanisms to operate properly inside system
constructions containing safety-related components. Build systems that enable these functions and mech-
anisms to perform properly, based on a full understanding of their operation.
• Typical related international standards: ISO 14119, Safety of Machinery -- Interlocking Devices Associ-
ated with Guards -- Principles of Design and Selection
Installation of Safety Device
The construction and installation of systems with safety-related components for equipment or facilities must
be performed by technicians who have received suitable training.

General Principles for Design IEC 61508, Safety Standard for Safety Instrumented Systems (Func-
tional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems)
Complying with Laws and Regulations
This safety device conforms to the relevant regulations and standards, but make sure that it is used in com-
pliance with local regulations and standards for the equipment or facilities in which it is applied.
• Typical related international standards: IEC 60204, Safety of Machinery -- Electrical Equipment of
Machines
Observing Precautions for Use
When putting the selected safety device to actual use, heed the specifications and precautions in this Op-
eration Manual and those in the Instruction Manual that comes with the product. Using the product in a man-
ner that deviates from these specifications and precautions will lead to unexpected failures in equipment or
devices, and to damages that result from such failures, due to insufficient operating functions in safety-re-
lated components.
Moving or Transferring Devices or Equipment
When moving or transferring devices or equipment, be sure to include this Operation Manual to ensure that
the person to whom the device or equipment is being moved or transferred will be able to operate it properly.
