Warning:
which, if not avoided, could result in death or serious injury.
DANGER indicates a hazard with a high level of risk which, if
Danger:
not avoided, will result in death or serious injury.
Operator
This operation manual is intended for those who have knowledge of machinery
using pneumatic equipment, and have sufficient knowledge of assembly,
operation and maintenace of such equipment. Only those persons are allowed
to perform assembly, operation and maintenance.
Read and understand this operation manual carefully before assembling,
operating or providing maintenance to the product.
Safety Instructions
Warning
Do not disassemble, modify (including changing the printed circuit board) or repair.
An injury or failure can result.
Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.
Do not operate in an atmosphere containing flammable or explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof.
If using the product in an interlocking circuit:
•Provide a double interlocking system, for example a mechanical system.
•Check the product regularly for proper operation.
Otherwise malfunction can result, causing an accident.
The following instructions must be followed during maintenance:
•Turn off the power supply.
•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance.
Otherwise an injury can result.
Caution
After maintenance is complete, perform appropriate functional inspections.
Stop operation if the equipment does not function properly.
Safety cannot be assured in the case of unexpected malfunction.
Provide grounding to assure the safety and noise resistance of the Fieldbus system.
Individual grounding should be provided close to the product with a short cable.
NOTE
When conformity to UL is necessary the SI unit must be used with a UL1310
Class2 power supply.

Exchange of SI unit
•Remove screws from End Plate and release connection of each unit.
•Replace old SI unit with new one. (Tie rod does not need to be removed.)
•Connect Input Block and End Plate and tighten removed screws by specified
tightening torque. (0.6 Nm)
Assembly and disconnection of unit
Addition of Input Block
•Remove screws from End Plate.
•Mount attached tie rod.
•Connect additional Input Block.
•Connect End Plate and tighten removed screws by specified tightening torque.

Caution for maintenance
(1) Be sure to turn-off all power supplies.
(2) Be sure that there is no foreign object in any of units.
(3) Be sure that gasket is lined properly.
(4) Be sure that tightening torque is according to specification.
If these items are not kept, it may lead to the breakage of substrate or intrusion of
liquid or dust into the units.

Power for sensor is supplied to sensor connected with Input block. Select sensor
concerning voltage drop up to maximum 1 V inside the unit at this moment.
If sensor requires 24 V, it is necessary to lower power supply voltage for sensor
slightly or secure power supply for sensor separately without going through SI unit so
that sensor input voltage can be 24 V with actual loading (allowable voltage of power
supply: 19.2 V to 28.8 V).

The setting of each switches can be fixed after power is ON.
Terminating resistance and cable
If this SI unit is the terminal of CC-Link connection, connect the terminal resistor to
"OUT" side of the bus adapter. There are two types of terminal resistors depending on
the cable to use.
Refer to the following table and select an appropriate terminal resister.
