Isolation: I/O to transmission section to power

Station No. setting: 2 rotary switches; 00 – FF (256)

■ Controller & Transmission Sections

Power indicator: Red LED turns ON in normal conditions;

OFF when the voltage level becomes low.

RUN indicator: Red LED turns OFF in error.

■ I/O Section

Contact I/O indicator LED: Red LEDs turn on when the

respective I/O channels are ON.

Analog I/O CPU RUN indicator LED: Red LED turns ON when

the CPU function proves normal, OFF in error.

■ RUN Contact Output: Contact opens in error.
