  • Page 4: Introduction

    1. INTRODUCTION This manual describes how the AD-8923-CC remote controller works and how to get the most out of it in terms of performance. Read this manual thoroughly before using the AD-8923-CC and keep it at hand for future reference.

  • Page 5: Applicable Instruments

    1.2. Applicable Instruments The AD-8923-CC functions in two ways as follows, depending on the weighing instrument used: A remote controller that displays the weighing data and remotely controls the weighing instrument. A remote display that displays the weighing data. Available key operations depend on the weighing instrument used. (Refer to “Table 2”) For weighing instruments not listed in this table, please refer to the A&D website.
  • Page 6 Note 1) Switching the standby or weighing mode is available for the AD-4212C/D/F. Note 2) Not available for the counting mode or percent mode. Note 3) Not available for the AD-4212A/B. Note 4) For weighing instruments other than AD-4212C/D/F, the AD-8923-CC displays " ". Use the display on the balance.

    Displays the weighing data received. When the unit is “g” (gram), the unit indicator turns on. If the balance outputs RS-232C weighing data that exceeds six digits, the AD-8923-CC does not display the high-end digits. (2 highest digits for an 8 digit display) Weight value of the CC-link is output even if it exceeds six digits.

    3.5. Performing Sensitivity Adjustment with the AD-4212C/F The following is the sensitivity adjustment procedure when the AD-4212C/F is connected. (An external weight is used.) Caution Do not allow vibration, drafts or temperature change to affect the AD-4212C during sensitivity adjustment. Caution on using an external weight The accuracy of the weight can influence the accuracy of weighing.

Press If you want to cancel sensitivity adjustment, press the CAL key.

  • Page 16: Function Setting

    4. FUNCTION SETTING Function setting specifies the AD-8923-CC performance. The parameters are stored in non-volatile memory, and are maintained even if the power line or AC adapter is removed. The function setting menu consists of two layers. The first layer is the “Class” and the second layer is the “Item”.

  • Page 17: Display And Keys

    4.1. Display and keys The STABLE indicator turns on to indicate that the parameter displayed is in effect. Selects a class or item. Changes the parameter. When a class is displayed, moves to an item in the class. When an item is displayed, stores the new parameter and displays the next class. When an item is displayed, cancels the new parameter and displays the next class.

  • Page 20: Cc-Link Connector

    6. 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. The setting values of CC-Link are changed in the function setting 6.1.

  • Page 25: Timing Chart

    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.

  • Page 27: Fixing The Decimal Point Position

    Even if the minimum display is switched using the SAMPLE key, the digits of the weight values output via CC-Link align with each other. If the balance outputs RS-232C weighing data that exceeds six digits, the AD-8923-CC does not display the high-end digits (it outputs to the CC-Link).
