Close across the unused input terminals as shown below.

Unused channels left open are equal to the burnout, which

turns the red ERR LED on and sets a burnout flag at the

PLC or the host device.

Unused channels can be specified and set so on the PC

Configurator Software (model: R3CON) without needing to

short at the field terminals.
