Installation Manual 45 Y1-03-0212 Rev.B5.2 Alarm CodesID Description Text Cause/Source System Reaction / Remedy01 AIS: Tx malfunction VHF Antenna,cablingReaction: The transponder unit stops transmission. If Alarm ID 01 andID 02 are simultaneously displayed, then a major antenna problem hasarisen.Remedy:Check if the antenna is AIS compatible (156-162 MHz) and if theantenna cabling has a short circuit or is missing any contacts at theconnectors.If the ID 01 is displayed as a stand alone message, then the unitrequires replacing.02AIS: Antenna VSWRexceeds limit(VSWR - VoltageStanding Wave Ratio)VHF antenna,installationReaction: The transponder unit continues transmission.Remedy:Check the antenna and the antenna cabling (RG214 / 50 Ohm cablerequired).03 AIS: Rx channel 1malfunction04 AIS; Rx channel 2malfunction05 AIS: Rx channel 70malfunctionInternal errorReaction: The transponder unit stops transmission on the affectedchannel,Remedy;If this alarm reoccurs regularly, then the transponder unit requiresreplacing.06 AIS: General failure Internal errorReaction: The transponder unit stops transmission.Remedy;The transponder unit requires replacing.25AIS; External EPFS lost(EPFS = electronicPosition Fixing Systemsuch as GPS)No valid data onCh1, Ch2 or Ch3is availableReaction: The transponder unit continues operation using the positiondata of the internal GPS. If there is no valid position data available fromthe internal GPS, error 026 is additionally displayed.Remedy:Id 25 indicates that the sentences GLL, GNS, GGA, RMC cannot bereceived. Check the sensor and the cabling; check if the system thatdelivers the data is working. Check the baud rate settings of the sensorinputs. AIS requires the protocol NMEA 0183 V3.0!26 AIS: No sensor positionin useNo valid positionfrom internal GPSor externalposition sensorReaction: The transponder unit continues operation.Remedy:Check the sensor cabling and the antenna of the internal GPS sensor.29 AIS: No valid SOGinformationNo valid data fromexternal speedsensor or internalGPSReaction: The transponder unit continues operation and displays SOG:N/ARemedy:The sentences VBW, VTG, RMC cannot be received. Check the sensorand the cabling; check if the system that delivers the data is working.Check the baud rate settings of the sensor inputs. AIS requires theprotocol NMEA 0183 V3.0!30 AIS: No valid COGInformationNo valid data fromexternal sensor orinternal GPSReaction: The transponder unit continues operation and displays COG:N/ARemedy:The sentences VBW, VTG, RMC cannot be received. Check the sensorand the cabling, check if the system that delivers the data is working.Check the baud rate settings of the sensor inputs. AIS requires theprotocol NMEA 0183 V3.0!32 AIS: Heading lost/invalidNo valid data fromexternal sensor(Gyrocompass)Reaction: The transponder unit continues operationRemedy:The sentence for HDT cannot be received. Check the sensor and thecabling, check if the system that delivers the data is working. Check thebaud rate settings of the sensor inputs. Mention AIS accepts trueheading only (no magnetic).35 AIS: No valid ROTInformationNo ROT indicatoris used.No valid data fromexternal sensorReaction: The transponder unit continues operationRemedy:The sentence for ROT cannot be received. If a Rate Of Turn indicator isnot in use, then it suffices to just acknowledge the alarm. The AlarmStatus will store the information that no ROT sensor is available.Otherwise, check the sensor and the cabling. Check if the system thatdelivers the data is working. Check the baud rate settings of the sensorinputs. The AIS requires the protocol NMEA 0183 V3.0!
