  • Page 10  When connecting the AD-8923-CC to the CC-Link network using the connector provided (721-105 / 037-000 equivalent), use the ferrule listed below (sold separately). (Example: when using the FANC-110SBH cable) Insert the cable into the ferrule and crimp it using the Variocrimp4 206-204 crimping jig, and insert it into the connector.

  • Page 11: Turning The Power On

     Do not share the power line with other devices.  Strong noises introduced from other devices may cause damage to the AD-8923-CC.  Inrush current from other devices may cause the AD-8923-CC not to start up properly.  Circuit configuration of the AD-8923-CC may affect other devices to prevent them from functioning properly.
  • Page 12  Be sure to add a noise filter on the front end of the switching power supply and ground the FG terminal.  This will increase the resistance against noises.  Be sure to ground the FG terminal of the AD-8923-CC and weighing instruments.  This will increase the resistance against noises.

  • Page 20: Cc-Link Connector

    CC-Link CONNECTOR The AD-8923-CC CC-Link is a remote device station of CC-Link ver.1.10. When a CC-Link is used, the AD-8923-CC can be controlled by the PLC remote I/O or remote registers. So, the program can be simple. And connection to a PLC is simple, thus, a weighing system can be built easily.

    Below examples are when the station number is set to 1. When connecting to a power supply When the AD-8923-CC is connected to a power supply and the CC-Link is ready, the request flag of initialization (RX0018) becomes active. The master station confirms that RX0018 is active, performs initialization and turns the reply flag of initialization (RY0018) ON.
  • Page 26 CPU operation The CPU normal operation (RX0006) is a signal to check that the AD-8923-CC is connected to a power supply and it functions normally. During normal operation, the signal is reversed at an interval of 0.5 to 1 second.
