• Sink logic
• Pr.128 = "20"
• Pr.182 = "14"
• Pr.190 = "15"
• Pr.191 = "14"
• Pr.192 = "16"
*1 Prepare a power supply matched to the power supply specifications of the detector.
*2 The applied output terminals differ by the settings of Pr.190 to Pr.196 (Output terminal function selection).
*3 The applied input terminals differ by the settings of Pr.178 to Pr.189 (Input terminal function selection) Assigning the PID control valid (X14)
signal to an input terminal enables PID control to be performed only when the X14 signal is turned ON.
*4 The AU signal need not be input.
 Selection of deviation value, measured value and set point input method,
and PID action method (Pr.128, Pr.609, Pr.610)
• Using Pr.128, select the input method for the PID set point, measured value detected by the meter, and externally
calculated deviation. Also, select forward or reverse action.
