5.2 Alarm Codes
ID
Description Text
Cause/Source
System Reaction / Remedy
01
AIS: Tx malfunction
VHF Antenna,
cabling
Reaction: The transponder unit stops transmission. If Alarm ID 01 and ID
02 are simultaneously displayed, then a major antenna problem has
arisen.
Remedy:
Check if the antenna is AIS compatible (156-162 MHz) and if the antenna
cabling has a short circuit or is missing any contacts at the connectors.
If the ID 01 is displayed as a stand alone message, then the unit requires
replacing.
02
AIS: Antenna VSWR exceeds
limit (VSWR - Voltage Standing
Wave Ratio)
VHF antenna,
installation
Reaction: The transponder unit continues transmission.
Remedy:
Check the antenna and the antenna cabling (RG214 / 50 Ohm cable
required).
03
AIS: Rx channel 1 malfunction
Internal error
Reaction: The transponder unit stops transmission on the affected
channel,
Remedy;
If this alarm reoccurs regularly, then the transponder unit requires
replacing.
04
AIS; Rx channel 2 malfunction
05
AIS: Rx channel 70 malfunction
06
AIS: General failure
Internal error
Reaction: The transponder unit stops transmission.
Remedy;
The transponder unit requires replacing.
25
AIS; External EPFS lost (EPFS
= electronic Position Fixing
System such as GPS)
No valid data
on Ch1, Ch2 or
Ch3 is available
Reaction: The transponder unit continues operation using the position
data of the internal GPS. If there is no valid position data available from
the internal GPS, error 026 is additionally displayed.
Remedy:
Id 25 indicates that the sentences GLL, GNS, GGA, RMC cannot be
received. Check the sensor and the cabling; check if the system that
delivers the data is working. Check the baud rate settings of the sensor
inputs. AIS requires the protocol NMEA 0183 V3.0!
26
AIS: No sensor position in use
No valid
position from
internal GPS or
external
position sensor
Reaction: The transponder unit continues operation.
Remedy:
Check the sensor cabling and the antenna of the internal GPS sensor.
29
AIS: No valid SOG information
No valid data
from external
speed sensor or
internal GPS
Reaction: The transponder unit continues operation and displays SOG:
N/A
Remedy:
The sentences VBW, VTG, RMC cannot be received. Check the sensor
and the cabling; check if the system that delivers the data is working.
Check the baud rate settings of the sensor inputs. AIS requires the
protocol NMEA 0183 V3.0!
30
AIS: No valid COG Information
No valid data
from external
sensor or
internal GPS
Reaction: The transponder unit continues operation and displays COG:
N/A
Remedy:
The sentences VBW, VTG, RMC cannot be received. Check the sensor
and the cabling, check if the system that delivers the data is working.
Check the baud rate settings of the sensor inputs. AIS requires the
protocol NMEA 0183 V3.0!
32
AIS: Heading lost/invalid
No valid data
from external
sensor
(Gyrocompass)
Reaction: The transponder unit continues operation
Remedy:
The sentence for HDT cannot be received. Check the sensor and the
cabling, check if the system that delivers the data is working. Check the
baud rate settings of the sensor inputs. Mention AIS accepts true
heading only (no magnetic).
35
AIS: No valid ROT Information
No ROT
indicator is
used.
No valid data
from external
sensor
Reaction: The transponder unit continues operation
Remedy:
The sentence for ROT cannot be received. If a Rate Of Turn indicator is
not in use, then it suffices to just acknowledge the alarm. The Alarm
Status will store the information that no ROT sensor is available.
Otherwise, check the sensor and the cabling. Check if the system that
delivers the data is working. Check the baud rate settings of the sensor
inputs. The AIS requires the protocol NMEA 0183 V3.0!
53
AIS: BATTERY SOON LOW
Battery is soon
out of capacity
Reaction: Own ship data is lost after powering on/off the system.
Remedy: consider to contact Technical Support for additional help
55
AIS: PRESS ENTER TO EXIT
1W/AUTO TX MODE
Conditions for
enabling 1 Watt
TX power are
not valid
Reaction: Conditions for enabling 1 Watt TX power are not valid.
This means that:
the speed is >3kn and / or
the navigational status is NOT moored / at anchor and / or
the ship type is NOT “Tanker”
Remedy:
Check the conditions (SOG, Navstat, Shiptype)
if GPS is valid ( a invalid GPS causes also this alarm)
