Specifications

69
009 Internal / external
GNSS position
mismatch
Internal or External GPS or
Antennas
The Transponder continues operation, but as this
might imply that wrong position is used. Care should
be taken as this might impose a risk both for own
and other ships.
Check the positioning of the GPS antennas.
Disconnect the External GPS and check if
the internal GPS provides the correct position.
010 Navigational
Status incorrect
Setup or speed sensor
(Navigational status does not
correspond with the given speed)
The Transponder continues operation. Check
that navigational status is not at anchor, moored
or aground while SOG >3 knots.
Check that navigational status is not under way
while SOG = 0 knots.
Check that SOG is correct.
011 Heading sensor
offset
COG sensor / HDT sensor
Alarm ID 11 is activated when
SOG is greater than 5 knots and
the difference between COG and
HDT is greater than 45 degrees
for 5 min.
The Transponder continues operation. Alarm
indicates mismatch between Course Over ground
and True heading. Check sensors. If current speed
is < 5knots, check SOG.
014 Active AIS SART AIS Search and rescue beacon
activated
The Transponder continues operation. Contact
local RCC (
Rescue Coordination Centre). Be
prepared to assist in search and rescue operation.
Listen on VHF channel 16 for additional
information.
025 External EPFS lost
(External Satellite
Positioning
System)
No valid position data on sensor
ports
The Transponder continues operation with the
internal GPS receiver. If no valid position is present
on the internal sensor, ALR26 is also displayed.
Check antenna and connections for EPFS, check
sensor. Check baud rate settings.
026 No sensor position
in use
Internal and external GPS sensor
The Transponder continues operation. Check
cabling and antenna for the internal GPS sensor. At
start up the GPS might need some time to receive
almanac data. Up to 15 minutes might be required.
029 No valid SOG
information
Internal and external speed sensor
The Transponder continues operation using default
data.
Check wiring and external sensor.
Check baud rate settings.
030 No valid COG
information
Internal and external course sensor
The Transponder continues operation using default
data.
Check wiring and external sensor.
Check baud rate settings.
032 Heading
lost/invalid
External heading sensor The Transponder continues operation using default
data.
Check wiring and external sensor.
Check baud rate settings.
