• Unused Input Channels

Close across the unused input terminals with a resistor as

shown below and set the DIP switch for Pt 100 input.

Unused channels left open are equal to the burnout, which

turns the red ERR LED on and sets a burnout

ag at the

PLC or the host device.

Unused channels can be specied and set so on the PC Con-

gurator Software (model: R3CON) without needing to con-

nect resistors at the eld terminals.
