    To prevent accidents arising from the misuse of this controller, please ensure the operator using it receives this manual. Please read this Communication instruction manual along with the Insruction manual for PC-900. Warning Turn the power supply to the instrument off before wiring or checking. Working or touching the terminal with the power switched on may result in severe injury or death due to Electric Shock.

    Setting value digital transmission (SVTC) • When the option C is applied to the PC-900, and if the Setting value digital transmission is selected during Communication mode by the front keypad, the main setting value of the PC-900 can be digitally transmitted to the FCD-100 or FCR-100 units that have option C. (Refer to the instruction manual for PC-900 on page 65) Only one FCD-100 or FCR-100 can be connected to the PC-900 at a time.

    2. Wiring connection Warning Turn the power supply to the instrument off before wiring or checking it. Working or touching the terminal with the power switched on may result in severe injury or death due to Electric Shock. Moreover, the instrument must be grounded before the power supply to the instrument is turned on.

    The instrument number (address) of the slave does not coincide with that of the command. The instrument number (address) is duplicated in multiple slaves. (See p.6) When communicating without using Shinko communication converter (IF-300-C5), make sure that the program is appropriate for the transmission timing. (See p.7) Check if the setting value memory number of FCD-100 or FCR-100 is set to 1 when using Setting value digital transmission (option: SVTC) function (See p.4)
