Fault Description Text Cause/Source
Reaction of the System
Remedy
001
A
IS: Tx malfunction VHF Antenna,
cabling
Reaction:
The Transponder Unit stops the transmission.
Remedy:
Check of the antenna and the antenna cabling (short
circuit or missing contact at the connectors)
002
A
IS: Antenna VSWR
exceeds limit
(VSWR = Voltage Standing
Wave Ratio)
VHF antenna,
installation
Reaction: The Transponder Unit continues operation.
Remedy:
Check of the antenna and the antenna cabling (75 Ω
cable instead of 50 Ω cable)
003
A
IS: Rx channel 1
malfunction
004
A
IS: Rx channel 2
malfunction
005
A
IS: Rx channel 70
malfunction
Internal error
Reaction:
The Transponder Unit stops the transmission on the
affected channel.
Remedy:
The Transponder Unit must be exchanged.
006
A
IS: General failure Internal error
Reaction:
The Transponder Unit stops the transmission.
Remedy:
The Transponder Unit must be exchanged.
008
A
IS: MKD connection lost
(MKD = Minimum Keyboard
Display)
No
Operating/Display
Unit connected
Reaction:
The Transponder Unit continues operation.
Remedy:
The Display Unit does not communicate with the
Transponder Unit. Check the cabling/connection of the
Primary Display Port. Check if the Display Unit is
working.
025
A
IS: External EPFS lost
(EPFS = Electronic Position
Fixing System such as
GPS)
No valid position
data at interface
S1, S2, S3
Reaction:
The Transponder Unit continues operation with the
position data of the internal position sensor. If there is
no valid position data available from the internal
position sensor, additionally error 026 is displayed.
Remedy:
The telegrams GLL, GNS, GGA, RMC can not 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.
026
A
IS: No sensor position in
use
No valid position
from internal
position sensor
Reaction:
The Transponder Unit continues operation.
Remedy:
Check the cabling and the antenna of the internal GPS
sensor.
