Also, the controller recognizes the voltage between the wiper input and B- as the
applied throttle voltage and not the voltage from the voltage source relative to
the Pot Low input.
For either throttle input, if the 0–5V throttle input (Pin 4 or 21) exceeds
5.5V relative to B-, the controller will register a fault and shut down.
