Summary of Product Parts
Installation
<EX180-SDN3 /SDN4 /SDN5 /SDN6 >
EX180-TFO09
This product is class A equipment that is intended for use in an industrial
environment.
There may be potential difficulties in ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbances.
NOTE
When conformity to UL is necessary the SI unit must be used with a UL
1310 Class2 power supply.
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.
Display
LED diagnostic display.
Setting switches
Switches to set the MAC ID and
communication speed (inside the cover).

General Instructions on Installation
Applicable valve series
The EX180 series SI unit can be mounted on the following valve
manifolds.
SJ2000/3000, S0700 series
∗
: Refer to the catalogues and operation manuals for details of the solenoid
valves and manifolds.
•
How to mount the manifold
1. Mount the SI unit to the manifold so that the mounting guide of the
SI unit case mates with the manifold groove.
2. Secure the SI unit using the two sliding locks.

2. Wiring of the power supply
Connect the power supply to the power supply connector (1 pc.).
The EX180 power supply structure consists of two supplies.
These supplies can be operated using a single or dual power supply
system.
Connect the wires to the assigned pins. (Figure 4, Figure 5)
The required tightening torque is 0.22 to 0.25 Nm.
•Note
Connect the FG terminal to ground with a ground resistance of
100 Ω or less.
