4.3 ANALOG VOLTAGE INPUT (1-5 V) WITH GUARD
A voltage signal can be used as the Command Input as shown in Figure 4-2. In this
example, a Bristol Babcock, METATONE B, Analog FSK Tone Receiver (Model 8772-31B)
provides the input to the Remote Set Regulator. Switch SW2-8 must be set to the OPEN
position to accommodate a 1-5 V input.
