10. Reattach the sensor adapter cover.
11. Insert the fixing plate to the original location, then fasten two binding screws loosened at step 3.
12. Fix the internal wiring cable released at step 2 with the wire saddle.
13. Check the checkmark(s) on the label on the rear side of the junction box cover, according to the additional
unit(s).
14. Reattach the junction box cover.
When an additional sensor adapter(s) is installed, set the termination resistor and Modbus address.
• Termination resistor: Use the jumper block J25 to set the termination resistor ON/OFF. For the first and last sensor adapter
in a series, short between 1 and 2 pin to set the termination resisitor ON. For other sensor adaper, short between 2 and 3 pin
of to set the termination resisitor OFF.
• Modbus address: Use the rotary switch U18 to set the Modbus address number.
Check the checkmark(s)
according to the additional unit(s).
