CAUTION
■
UNUSED INPUT CHANNELS
Set the unused channels to -20 – +20 mA or 0 – 20 mA range. Otherwise, set them as “Unused” with PC Configurator software: R3CON. Unused channels left open with 4 – 20 mA setting are equal to the input lower than -15 %, which sets a data abnormality at the PLC or the host device.
