wind angle, and more rudder will be commanded.
When running, it is difficult to steer the boat with waves coming sideways or from behind.
The waves may yaw the boat into an unwanted gybe; this can be hazardous for both the crew
and the mast.
The gybe prevent function will be activated when the actual apparent wind angle becomes
greater than 175° or gets opposite to the set wind angle. More rudder will be commanded to
prevent an unwanted gybe.
The tack and gybe prevent functions are not a guarantee against getting into a hazardous
situation. If the effect of the rudder and/or drive unit is not adequate, a dangerous situation
may occur. Pay particular attention in such situations.
Wind steering and navigation
In Wind Nav the Autopilot steers the boat given both wind data and
track data from the Zeus Touch navigation function.
In Wind Nav mode the Autopilot calculates the initial course change
needed to navigate towards the active waypoint, but the Autopilot
will also utilize the current wind direction in the calculation.
Using the Zeus Touch in an AP24/AP28 system
Command transfer
If your Zeus Touch unit is connected to an Autopilot system including
an AP24 or AP28 control unit, only one control unit can be active at the
same time. An inactive unit is indicated with an envelope symbol in the
display.
You can take command from an inactive Zeus Touch unit with active Autopilot pop-up by
turning or pressing the rotary knob.
If the pop-up is not displayed, you can take command from the Zeus Touch unit by pressing
and holding the STBD/AUTO key to bring up the mode selection menu, and then confirming
active mode.
Locking remote stations
The AP24/AP28 includes a Remote Lock function that will disable all
other control units. A locked unit is indicated with a key symbol.
When the remote lock function is enabled on AP24/AP28 no transfer
of command to Zeus Touch or other AP heads on the system can take
place, only the active AP control unit stays in command.
You can only unlock the remote stations from the AP24/AP28 unit in command.
Using the Autopilot in an EVC system
When the Zeus Touch is connected to an EVC system via the SG05, you can take manual
control of the steering irrespective of the Autopilot mode.
The mode indicator on the Autopilot pop-up will be replaced by a dash to indicate EVC
override.
The system will return to Zeus Touch control in standby mode if no rudder command is given
from the EVC system within a predefined period.
