5. When will the Segway HT give a Stick Shake Warning?
> Riding aggressively, accelerating or stopping abruptly.
> Riding against the Handlebar.
> Riding on rough terrain or steep slopes.
> Riding against an obstruction.
> Riding backward.
> During Safety Shutdown.
> Moving a Segway HT with no rider on the Platform while in Balance Mode.
> Stepping onto a Segway HT Platform while in Power Assist Mode.
6. Describe Rider Detection.
The Segway HT detects the absence or presence of a rider on the Platform by reading the pressure
on the Rider Detect Sensors.
7. What safety mechanism does the Rider Detection perform?
It attempts to stop the Segway HT from moving with no rider on. On an i or p Series, this takes much
longer if released at speed, than from a stationary position. On an e Series, this function is overridden
by the E-Stand function.
8. When will the Segway HT perform a Safety Shutdown?
When there is a critical component or system malfunction in the:
• Controller Board
> Motor
> Battery Pack
> Balance Sensor Assembly (BSA)
> Handlebar systems
> Control Shaft cord
> Excessive rate sensor error
> Systems communication failure
9. What does the Segway HT do during a Safety Shutdown?
If the Segway HT detects a fault in any of its redundant subsystems, the Segway HT notifies you by
automatically reducing its speed, shaking its Handlebar, making growling and beeping noises, and
flashing red in the Display.
10. When might the Segway HT stop balancing, even with a person on the Platform, prior to the end
of the 10-second window?
When pitch limit is exceeded (usually backward, 20°)
