Fault Recovery
When a fault is detected by the speed controller, the speed controller will attempt to recover from the fault and resume
normal operation. In the case of an intermittent problem such as a loose wiring connection, the controller may be able
to recover and operate normally for a while, but the problem should be repaired before placing the vehicle in service.
Depending on the type of fault, the controller will attempt to recover immediately after the condition clears or after the
accelerator pedal has been cycled (released and pressed again).

The following faults can be detected by the Excel System controller:
HW FAILSAFE
The armature drive FET's (field effect transistors) regulate the armature current. If the speed controller detects a failure
of the armature drive FET's or circuitry, a hardware failsafe fault is detected.
What it means: A catastrophic failure internal to the controller on either the power board or the logic board.
What to do: Replace controller.
THROTTLE FAULT
If the throttle position sensor or MCOR (Motor Controller Output Regulator) voltage is less than 0.20 volts or greater
than 4.80 volts, the controller detects a throttle fault.
