• Unused Output Channels

Close across the unused output terminals as shown below.

Unused channels left open are equal to the wire breakdown,

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 Configu-

rator Software (model: R3CON) without needing to short at the

field terminals.
