•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.

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.

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.

5 FE Ground
Example of the cable with connector: EX9-AC
FE connection
Connect the ground terminal to the ground. Resistance to the ground should be 100 Ω
or less.
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 drop of max. 1 V

Terminating resistors
DeviceNet TM requires a terminating resistor to be installed at each end of the trunk.
The resistor requirements are:
•121 Ω
•1% metal film
•1/4 W
Terminating resistors should not be installed at the end of a drop line, only at the two
ends of trunk line.
LED indication
EX250
LED
PWR(V) Green LED is ON when power for solenoid valve is supplied.
PWR Green LED is ON when power for DeviceNet
OFF Power supply is off, on-line status or checking for MAC ID duplication.
Green LED is flashing I/O connection stand-by (on-line status)
MOD/NET Green LED is ON I/O connection established (on-line status)
Red LED is flashing I/O connection time-out (minor communication error)
Red LED is ON MAC ID duplication error or BUS OFF error (serious communication error)
: EX250-SDN1 disconnects the I/O connection when the solenoid valve power supply decreases or
when the input block fuse is detected to be broken (EX250-SDN1-X102 does not disconnect the I/O
connection).
Setting
Switch setting
Open the protective cover, and set the switches with a small flat blade screwdriver.
Note
1. The power supply should be off while setting the switches.
2. Be sure to set the switches before use.
3. After setting the switches, close the switch cover and tighten the screw to the
specified torque. (Tightening torque: 0.6 Nm)

: Output No. starts from 0, and will be assigned to the valves in order from the SI unit mounted side
: Manifold wiring is double wired as standard ("double wiring specification"), and the output
numbers are assigned in order from A side to B side. If the mounted valves are single solenoid
valves, the output on B side will be empty. (See Figure a)
: Special wiring specification with a mixed wiring of single solenoid and double solenoid can be
specified with a wiring specification sheet. This makes it possible to specify the output numbers
without empty outputs. (See Figure b)
: Each bit status, 0 or 1, of the data shows the ON or OFF solenoid valve status (0: OFF, 1: ON),
and the output number starting from 0 will be assigned to from the lowest bit of the memory data.
