    ○Terminal block (with switch cover open) Element Description Output connector To connect to the valve manifold LED display to indicate the status of the SI unit. LED and Switch cover Switches for setting the station number and transmission speed. Communication terminals (DA, DB, DG) To connect the CC-Link line with a CC-Link-dedicated cable.

  • Page 13: Mounting And Installation

    Mounting and Installation ■Communication wiring The connection between a CC-Link-dedicated cable and an SI unit communication terminal for CC-Link is shown below. (1) Be sure to connect each signal line to its dedicated terminal. (Refer to Fig. 1) Tighten the screws securely with a torque of 0.5 to 0.6 N•m. The terminal screw is an M3 cross head screw.
  • Page 14 (4) The CC-Link-dedicated cable’s shield wire (SLD) should be connected to the “FG” terminal of the SI unit. For the EX12#-SMJ1, the "SLD terminal" and "FG terminal" are common. Therefore, connect 3 wires to the "FG Terminal" as shown in Fig. 4. Fig.

  • Page 15: Power Supply Wiring

    ■Power supply wiring Connect the power supply wiring to the solenoid valve power supply terminals and to the SI unit control power supply terminals. Although the power supply consists of two separate systems, it is possible to use either a single power supply or separate power supplies.

  • Page 16: Settings

    Settings ○Display setting Display Meaning LED is ON when the communication power is ON Indicates whether the SI unit is communicating with the master station correctly. L RUN LED is ON when the SI unit is receiving normal data from the master station. LED is OFF during time-out.
  • Page 17 ○Switch setting The setting for the station number and communication speed can be carried out using the rotary switches under the LED and switch cover. The settings must be carried out with the power supply for the SI unit turned off. •Station number setting Setting Setting range...

    Maintenance •Mounting and wiring Item to inspect Criteria Countermeasure Are SI unit terminals Tighten the connector. (for communication and power supply) No looseness (Refer to “Mounting/ Installation”) securely connected? Are the terminating resistors securely Connect suitable terminating resistors to connected to both ends of the network Terminating resistors must be cables.
  • Page 21 ○Fuse replacement (Only EX126D-SMJ1) If an over current occurs in the power supply for communication or the power supply for solenoid valves, due to a short circuit etc, the fuse will disconnect the supply. In this case, remove the cause of the over current and replace the fuse. The fuse replacement should only be performed with the SI unit disconnected from the valve manifold.
