Safety Shutdown
WARNING
Do not get back on the Segway PT after a Safety Shutdown until the condition
that caused the Safety Shutdown has been identified and corrected.
WARNING
Never restart and ride your Segway PT after it has indicated an empty Battery
condition or performed Safety Shutdown due to low Battery. The PT may not
have enough power to keep you balanced, especially if you demand a lot of
power at once. If you restart and continue riding, you risk falling. Also, you
risk damaging your Batteries, resulting in reduced Battery life and capacity.
If the PT detects a fault in any of its redundant systems or a Battery is
depleted beyond its safe limit, it performs a Safety Shutdown (Figure 30).
When a Safety Shutdown occurs, the PT automatically reduces its speed,
gives the Stick Shake Warning (shakes the Handlebar and makes growling
noises), flashes the Balance Indicator lights, emits a warning tone, and the
InfoKey Controller displays an unhappy face.
You have approximately 10 seconds from the start of a Safety Shutdown
to come to a controlled stop and step off. After 10 seconds, the PT will
immediately shut down when the Wheels reach zero speed.
If a Safety Shutdown occurs:
1. Immediately come to a controlled stop.
2. Carefully step off one foot at a time.
