CAUTION

■UNUSED INPUT CHANNELS

Set the unused channels to the ranges other than 1 - 5 V.

Otherwise, set them as "Unused" with PC Configurator

software: R3CON. Unused channels left open with 1 – 5 V

setting are equal to the input lower than -15 %, which sets a

data abnormality at the PLC or the host device.

Open circuit with the input range set to ±10 V means 50 %

of the full-scale. An alarm setpoint must be set to a value

that does not trip an unwanted alarm.

GENERAL SPECIFICATIONS
