11 Alarms
The following table list all the alerts defined in IEC 61993-2:Ed3 in addition to some Jotron specific ones. The alerts
are part of the Bridge Alert Management system. The legacy alarms are still triggered in parallel with the BAM
alerts, but the display only shows the BAM alerts.
The category column indicates if alert is Warning (W) or Caution (C).
ID Cat. Description Cause / Source of error Reaction of the system and user advise
3108 W Locating device Check AIS targets
Nearby AIS SART, AIS MOB or AIS EPIRB. 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.
3062 W General fault Check AIS equipment The Transponder will never trigger this alarm
3008 W Transceiver fail Not transmitting, check AIS
The Transponder stops transmission. (See footnote 1.)
Check that the MMSI number is correct.
Alternatively, service is required.
Not receiving, check AIS
The Transponder stops transmission on the affected channel.
Try rebooting the system. Alternatively, service is required
(See footnote 1.)
3015 W Lost position
Own ship position not
transmitted
The Transponder continues operation.
Check cabling and antenna for the internal GNSS sensor. At
start up the GNSS might need some time to receive almanac
data. Up to 15 minutes might be required.
3116 C Impaired radio
Reduced coverage
(antenna VSWR)
The Transponder continues transmission.
Check the VHF antenna and the cabling. Make sure the
cables are 50 Ohm
Ch1 inoperative, check AIS
The Transponder stops transmission on the affected channel.
Try rebooting the system. Alternatively, service is required.
(See footnote 1.)
Ch2 inoperative, check AIS
The Transponder stops transmission on the affected channel.
Try rebooting the system. Alternatively, service is required.
(See footnote 1.)
DSC inoperative
The Transponder continues normal transmission but is not
able to receive DSC messages.
Try rebooting the system. Alternatively, service is required.
3113 C Sync in fallback
Check AIS for UTC time
synchronisation
The Transponder continues operation using indirect or
semaphore synchronisation with other AIS units.
If the received GNSS signal strength is low, the GNSS might
use some time to get the first fix. Consider waiting 15
minutes.
Check the GNSS antenna and cabling.
If the antenna is an active type, check that the phantom DC
voltage is correct
3003 C Lost ext EPFS
Check external position
sensor
The Transponder continues operation with the internal GNSS
receiver. If no valid position is present on the internal sensor,
alert 3015 is also displayed.
Check antenna and connections for EPFS, check sensor.
Check baud rate settings.
3119 C Missing COG Not transmitting COG
The Transponder continues operation using default data.
Check wiring and external sensor.
Check baud rate settings.
