IMPORTANT MESSAGES
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
understand the contents before use.
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.
Indicates a potentially hazardous situation
that, if not avoided, may result in minor injury
or moderate injury.
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.
NOTE
Handling precautions
Use the following UL-recognized DC power supply to combine with.
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 )
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.
