the controller’s forward and reverse inputs independent of the throttle pot
resistance. The controller will not sense direction from the pot resistance.
With Type 1 throttles, broken wire protection is provided by the controller
sensing the current flow from the 2-Wire Pot pin through the pot and 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.

Ω
Throttle (“Type 3”)
The 0–5k
Ω
throttle (“Type 3” in the programming menu) is a 2-wire resistive
throttle that connects between the 2-Wire Pot pin (Pin 16) and Pot Low (Pin 14).
It doesn’t matter which wire goes on which pin. For Type 3 throttles, zero speed
corresponds to 0
Ω
and full speed corresponds to 5k
Ω
.
With Type 3 throttles, broken wire protection is provided by the controller
sensing the current flow from the 2-Wire Pot pin through the pot and 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.

not be tied to ground.
0–5V, 0–10V, 3-Wire Potentiometer, or Electronic Throttle (“Type 2”)
With these throttles (“Type 2” in the programming menu), the controller looks
for a voltage signal at either the pot wiper/0–5V input (Pin 15) or the 0–10V
input (Pin 5). Zero speed corresponds to 0V and full speed corresponds to either
5V or 10V. Pot Low (Pin 14) is the current return path for all Type 2 throttles.
It is 200 mV above B- and must have at least 0.1 mA flowing into it to prevent
pot faults.
