3.2 Operating in Wind Mode (WindTrim)
Wind mode (also known as WindTrim) allows the ST7000 Plus to
maintain a course relative to an apparent wind angle. It uses wind trim
to eliminate the effects of turbulence and short term wind variations,
and provides smooth precise performance under Wind mode operation
with minimal power consumption.
Wind mode uses the fluxgate compass as the primary heading
reference and, as changes in the apparent wind angle occur, the locked
compass heading is adjusted to maintain the original apparent wind
angle.
To use Wind mode, the ST7000 Plus must receive wind information
from one of the following sources:
• SeaTalk Wind instrument, connected to a ST7000 Plus via SeaTalk.
• NMEA wind information.
• Autohelm wind vane connected to a SeaTalk interface box.
Selecting Wind Mode
Wind mode can be selected from either Standby or Auto modes, as
follows:
1. Steady the vessel onto the required apparent wind angle.
2. Press standby and auto together to select Wind mode and lock
the current apparent wind angle.
• The locked heading is displayed along with the apparent wind
angle.
• The boat heading is adjusted by the pilot to maintain the locked
apparent wind angle.
