The power supply must be selected in accordance with the power specifications of the
detector used.
The used input signal terminal changes depending on the Pr. 178 to Pr. 189 "Input terminal
selection" setting.
The used output signal terminal changes depending on the Pr. 190 to Pr. 196 "Output
terminal selection" setting.
The AU signal need not be input.
