: Thread size: M3×30
Replacement of the SI unit
•Remove the M3 hexagon screws from the SI unit and release the SI unit
from the valve manifold.
•Replace the SI unit.
•Tighten the screws with the specified tightening torque. (0.6 Nm)
Precautions for maintenance
•Be sure to switch off the power.
•Check there is no foreign matter inside the SI unit.
•Check there is no damage and no foreign matter being stuck to the
gasket.
•Be sure to tighten the screws with the specified torque.
If the SI unit is not assembled properly, inside PCBs may be damaged or
liquid and/or dust may enter into the unit.
Assembly and disassembly of the SI unit
Connecting cables
Select the appropriate cables to mate with the connectors mounted on the
SI unit.

PROFIBUS DP address setting and Fail safe setting (SETTINGS)
<PROFIBUS DP address setting (ADDRESS)>
The PROFIBUS DP address is binary coded and can be set from 1 to
125 using the 8-element switch.
Note: Factory default setting is Address 1.
<Fail safe setting (OUTPUT STATE)>
Set the reaction of outputs to the communication error.
CLEAR: Clear all outputs.
HOLD: Hold the last state before communication error.
Note: Factory default setting is CLEAR.
Note: Be sure to switch off the power supply before setting the switches.
