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
04
AIS; Rx channel 2
malfunction
05
AIS: Rx channel 70
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.
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. AIS requires the protocol
NMEA 0183 V3.0!
NOTE: Alarm – Messages marked with asterisk (*) will appear on standard workboat
installations due to missing sensor input devices
