1.5. Travel, High Speed

When the steering control handle is between 41 to 79
degrees from the upper rest position, the ETAC (A2) verifies
that both arm angle switch (S24) and arm angle switch (S25)
are engaged for high speed travel mode. The voltage at M- of
the drive motor will vary from 24V to 0.5V. The voltage is
proportional to the position of the thumb controls. The drive
wheel rotates in the selected direction at a higher speed
proportional of the thumb controls.
