3. OPERATION
The Model FP-10 includes the following features:
• 0 – 5k potentiometer output which easily interfaces
with motor controller throttle inputs and avoids
the necessity of a dedicated power supply (Curtis
98191 potentiometer).
• Dual return springs to ensure safe operation. A
sudden reduction of pedal resistance of more than
50% indicates a single spring failure.
• Return spring failure detection switches monitor
each return spring and allow the vehicle designer
to signal the user of a potential throttle fault. The
spring failure detection switches can also be used
to implement a limp-home mode to ensure that
the vehicle can return to a safe location thereby
eliminating stranding the vehicle.
• The foot pedal includes two micro-switches to
indicate idle validation and full throttle further
ensuring safe vehicle operation.
