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.

Mounting and Installation
Installation
The SI unit does not have mounting holes, so it cannot be installed alone. Make sure to
connect the solenoid valve. When an input block is not required, connect the end plate
directly to the SI unit.

•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. (0.6 Nm)
Caution for maintenance

(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.

Example of connection cable: EX9-AC050-1 etc.
SW power is supplied to the sensor connected to the input block. There is a voltage drop up
to maximum 1 V inside the SI unit when SW power is supplied. Select a sensor taking this
voltage drop into consideration. If 24 V must be supplied to the sensor, it is necessary to
increase the SW power supply voltage so that the input voltage of the sensor will be 24 V with
the actual load. (Allowable SW power supply range: 19.2 V to 28.8 V)
Voltage reduction of approx.1V

Bus cable and termination resistors
The cables, connectors, and termination resistors used in CANopen networks shall
meet the requirements defined in ISO 11898. In addition, here are given some
guidelines for selecting cables and connectors.
The table below shows some standard values for DC parameters for CANopen
networks with less than 64 nodes.

For drop cables a wire cross-section of 0.25 to 0.34 mm
choice in many cases.
Besides the cable resistance, there should also be considered the real resistance of
the connectors, if calculating the voltage drop. The read resistance of one connector
should be in the range of 2.5 to 10 mΩ.
FE connection
Connect the ground terminal to the ground. Resistance to the ground should be 100 Ω
or less.

: Output numbers are assigned to stations from side D to U of manifold in order. (See manual of
each valve manifold for the directions of side D and U).
: Standard manifold is wired in double. Output numbers are assigned to side A and B alternatively.
In case of single solenoid valve, output on side B is free. (Refer to fig.a)
: Mixed (single and double) wiring is available as long as wiring specifications designate it. This
allows output numbers to be specified without having free output. (Refer to fig.b)
: Each bit of data sent from master (4 bytes) shows ON/OFF (0: OFF, 1: ON) of solenoid valve.
Starting from LSB of the first byte (Offset0), output numbers are assigned to all the bits in
numeric order.
