Safety Interlocks
If the BMS detects a serious internal fault, it can take
either or both of two actions to prevent damage to the
power pack:
1. Throttle Disable The BMS will disable the throttle
if the power pack is empty, or if the BMS detects
certain serious internal problems. You cannot ride
the motorcycle until the problem is resolved.
2. Charger Disable The BMS will prevent charging if
it detects certain serious internal problems, even
if the power pack is connected to a charger and
plugged in to AC power. The power pack cannot
be charged until the problem is resolved.
The Throttle Disable Interlock
The BMS communicates with the main motorcycle
control module. The BMS can send a signal to the
main motorcycle controller requesting that the throttle
control on the motorcycle be disabled. When the
throttle control is disabled, the motor will not deliver
power to the rear wheel, and the motorcycle cannot
be ridden.
If the throttle is disabled while riding, the motorcycle
will cease to provide power, and the operator must
pull over to a safe location.
All conditions which would cause the BMS to disable
the throttle are also signaled by a flash code pattern
at self-test. If you suspect that the BMS has disabled
the throttle control on your motorcycle, turn the key
switch OFF and back ON again to enter self-test
mode. The flash code pattern from the BMS will
report any of the error conditions which would cause
the BMS to disable the throttle.
Each of these conditions, the associated self-test
flash code pattern, and the suggested remedies, are
discussed in Understanding BMS Flash Code
Patterns on page 6-4.
