3-Wire Potentiometer (500 Ω –10k Ω ) Throttle
The 3-wire potentiometer is used in its voltage divider mode—with the voltage
source and return being provided by the controller. Pot High provides a current-
limited 5V source to the potentiometer, and Pot Low provides the return path.
Wiring is shown in Figure 9.

potentiometer throttle
(“Type 2”).
As with the 2-wire throttles, broken wire protection is provided by the
controller looking for a minimum current into the Pot Low pin. If the Pot Low
input current falls below 0.1 mA, a throttle fault is generated and the controller
is disabled. NOTE: The Pot Low pin (Pin 14) must not be tied to ground.
