SAFETY

The body of unit and this manual contain the essential information for the protection of users and others from possible injury and property damage and to ensure correct handling. Please check that you fully understand the definitions of the following messages ( symbols ) before going on to read the body of this manual, and always follow the instructions. Please also read the instruction manuals etc. of related machines and equipments and understand the contents before use.

IMPORTANT MESSAGES

Indicates a potentially hazardous situation that could result in death or severe injury if you do not follow instructions.

Read this manual and follow its instructions. Signal words such as WARNING, CAUTION and NOTE will be followed by important safety information that must be carefully reviewed.

Indicates a potentially hazardous situation that, if not avoided, may result in minor injury or moderate injury.

Gives you helpful information.

NOTE

Do not disassemble, modify ( including modification of printed circuit board ) or repair.

Otherwise injury or failure can result.

Do not operate beyond specification range.

Otherwise fire, malfunction or damage to the reduced wiring system can result. Confirm the specifications before operation.

Do not operate in atmosphere of flammable/explosive/corrosive gas.

Otherwise fire, explosion or corrosion can result. This reduced wiring system is not explosion-proof type.

For use in interlock circuit:

Provide double interlock system by adding different type of protection ( such as mechanical protection ). Check that the interlock circuit is working normally.

Otherwise accident caused by malfunction can result.

Before performing maintenance:

Turn off power supply. Stop air supply, exhaust compressed air in piping, and confirm the release to atmosphere.

Otherwise injury can result.

Conduct proper functional inspection after completing maintenance.

In the case of abnormality such as unit does not work normally, stop the operation. Otherwise safety cannot be assured due to unintended malfunction.

Provide grounding to improve safety and noise resistance of reduced wiring system.

Provide grounding as close to the unit as possible to shorten distance for grounding.

1. UL508-compatible limited voltage/current circuit A circuit using the secondary coil of an insulating transformer that meets following conditions as power source.

Maximum voltage ( at no load ): 30Vrms ( 42.4Vpeak ) or below Maximum current : ( 1 ) 8A or less ( including when short-circuited )

( 2 ) When limited by the circuit protector ( such as fuse )

having the following rating.

2. UL1310-compatible Class 2 power supply unit or circuit of max. 30Vrms ( 42.4Vpeak ) or less

using a UL1585-compatible Class 2 transformer as power source. ( Class 2 circuit )

Handling precautions

Use the following UL-recognized DC power supply to combine with.

SAFETY ( continued )

Follow the instructions given below when handling your reduced wiring system. Otherwise a damage or failure to cause a malfunction can result.

Operate the reduced wiring system at the specified voltage. Reserve space for maintenance. Do not remove any name plate or label. Do not drop, hit or apply an excessive shock to the unit. Follow the specified tightening torque. Do not apply any excessive force to cables by repeated bending, tensioning or placing a heavy object on the cables. Connect wires and cables correctly. Do not perform any wiring work while the power is on. Do not use the reduced wiring system on the same wiring route as the power line or high

voltage line. Confirm the insulation of wiring. Perform the power supply wiring by dividing into two lines ---- one is for power supply for output and the other is for power supply for input and controlling GW/SI. Take sufficient measures against noise such as noise filter when incorporating the reduced wiring system into a machine or equipment. Mount a terminal plug or a waterproof cap on each unused M12 connector for input/output

( communication connector, communication ports A - D, and power supply for input and

controlling GW/SI ). Take sufficient shielding measures when operating the product in any of the following places.

( 1 ) A place where noise due to static electricity etc. is generated

( 2 ) A place of high electric field strength

( 3 ) A place where exposure to radioactivity is possible

( 4 ) A place near power cable Do not operate the product in a place where there is a source of surge. Use a surge absorbing element built-in type to directly drive the load that generates surge voltage such as solenoid valve. Prevent any foreign matter such as remnant of wires from getting inside the product when opening the station number switch protective cover. Install the reduced wiring system in a place free from vibration and impact. Operate the product in the specified ambient temperature range. Do not use in a place to be affected by the radiant heat from a surrounding heat source. Set the DIP switch and rotary switch by using a sharp-pointed watchmakers screwdriver etc. Perform the maintenance regularly. Conduct an appropriate functional inspection after completing the maintenance. Do not use chemicals such as benzin and thinner to clean the product.

Product Summary

System configuration general

The reduced wiring system is connected to various kinds of fieldbus realizes the reduced wiring and decentralized installation of I/O devices. The signals to/from fieldbus are exchanged by GW unit, and the signals to/from decentralized I/O devices are collected and delivered by GW unit. The maximum number of connections of manifold valve/Input unit manifold is 16/branch x 4 branches = 64 points each for output and input.

As the cables with connectors are used for all wirings among devices, the system complies with the IP65 environment.
