Safety Precautions

1 Intended Audience

This manual is intended for the following personnel, who must also have knowl- edge of electrical systems (an electrical engineer or the equivalent).

•Personnel in charge of installing FA systems.

•Personnel in charge of designing FA systems.

•Personnel in charge of managing FA systems and facilities.

2 General Precautions

The user must operate the product according to the performance specifications described in the relevant manuals.

Before using the product under conditions which are not described in the manual or applying the product to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement ma- chines, safety equipment, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative.

Make sure that the ratings and performance characteristics of the product are sufficient for the systems, machines, and equipment, and be sure to provide the systems, machines, and equipment with double safety mechanisms.

Be sure to read this manual before attempting to use the Link Adapter and keep this manual close at hand for reference during operation.

!WARNING It is extremely important that the Link Adapter be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying the Link Adapter system to the above-mentioned applications.

3Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing so may result in electric shock.

!WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable Controller), including the following items, in order to ensure safety in the system if an abnormality occurs due to malfunction of the PC or another external factor affecting the PC operation. Not doing so may result in serious accidents.

•Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.

•The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a coun- termeasure for such errors, external safety measures must be provided to en- sure safety in the system.

•The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system.
