XTE Alarm: Sets an acoustic alarm to sound when the vessel is deviating from a
defined course. The user can select the desired alarm range or disable the
alarm.
Depth Alarm: Sets an acoustic alarm to sound when the received depth value
(from a depth sounder with NMEA output) is too shallow. The user can select the
desired depth alarm limit or disable the alarm (a line representing the depth
alarm limit is drawn on the Depth Graph).
Anchor Alarm: Sets an alarm to sound when the ship moves off a selected
location. The user can select the desired alarm range or disable the alarm.
Audible Alarm: Enable disable the alarm beep.
Grounding Alarm: The chart plotter is provided with a function that, by querying
the maps data, verifies potential danger to navigation due to shallow water, land,
rocks, obstructions and shoreline constructions. The maps are scanned perio-
dically (every 10 seconds).
When the Grounding Alarm is active, the chart plotter scans an area in front of
the boat. This area is identified by a triangle drawn in front of the boat icon whose
direction is determined by the current boat heading. The length of the triangle
is user selectable and its angle is 30 degrees.
If any of the above objects are found, the chart plotter notifies the danger on a
dedicated warning message box in the Grounding Alarm Report page.
Entering a value in the Grounding Alarm item activates the Grounding Alarm.
The Grounding Alarm is switched Off by default after a Master Reset. Once the
Grounding Alarm has been activated, a warning message is shown.
NOTE
- The Grounding Alarm function only operates with the new NT+ C-CARDs. It also
affects the speed of the redraw of the screen. If this function is not used it may
be disabled.
- When any of the objects checked are found for the first time, the chart plotter
shows a pop up window to alert the user of the possible danger. The name of each
new dangerous object found is reported in the warning window. In the Grounding
Alarm Report page the relative item has a tick marker next to it, to identify the
dangerous object currently detected. If in the next search cycle the same objects
are found again, the alarm window will not be shown. Instead, if in the next
searches the objects found before are no longer detected, their relevant item in
the Grounding Alarm Report page is cleared (note that in this case, if the same
object type is found again later, the Alarm will be shown). The chart plotter shows
an icon on the charts that identifies when a Grounding Alarm is detected.
Grounding Alarm Range: Allows setting the length of the sector to be detected
among 0.25, 0.5, 1.0 Nm. The default setting is 0.25 Nm. When any of the
searched objects is found in the scanned area, a tick marker is printed on the
relative box in the Grounding Alarm Report page to identify which dangerous
objects have been currently detected.
Grounding Alarm Report: Allows displaying the report of the dangerous objects
currently detected.
