③ CONTROL UNIT Power Wiring
1.3.3.1 ANALOG INPUT Wiring
▶ Be careful of the polarity of the signal. The wrong connection may cause a trouble.
▶ Use a shielded wire for analog input and the shield should be 1-point grounded.
▶ The wires of input signal should be apart from power line and grounding line.
▶ Use a wire of low resistance. The resistance difference between the wires is unfavorable especially for a
resistive sensor.
