CD VELOCI SPECIAL FEATURE
/Fl
t7 The VELOCI digital speed controls feature a new overheat protection function. This function protects the VELOCI against overheating
during operation. lf the speed controls temperature exceeds safe levels, the motor function will be temporarily switched off. However, full
steering function is still maintained during this period. When the overheat protection mode is activated, the setup LED will flash GREEN
and RED simultaneously. Simply wait a few minutes to allow the speed control to cool down to normal operating temperatures and full
function will be restored.
Overheating may be caused by the following:
a. Driving in reverse in excess of B seconds.
b. The motor used has less than factory limit of turns.
c. Gear mesh is too tight or other drivetrain problems.
d. Inappropriate gear ratios.
e. Repeatedly going from full reverse to full forward instantaneously.
f. Using full brakes too often.
g. Not enough ventilation to the speed control.
