Wiring the Analog Input Terminals
Wiring terminals VS and VF through analog voltage signal:
When analog voltage input signal is as the external power supply, wire terminals VS
and VF as per the method shown in Figure 3-12-a.
When analog voltage input signal is as the potentiometer, wire terminals VS and VF as
per the method shown in Figure 3-12-b.
