■ 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 lights 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.

Error detection

•Communication: The receiver units detect loss of

communication and wire break.

•CPU: Watch-dog timer

•Power voltage: Detects when the voltage supply to the

CPU drops by 10 %.

MULTIPLEX COMMUNICATION
