List of events
0855C-0 ADM
WARNING Pol cal. limits
Check limits of the calibration result for the
polarisation axis are exceeded. Pointing
performance may be degraded. Info: See 08559-0.
(!T,!G)
0855D-0 ADM
WARNING ISM warning
The ISM has temporarily observed an unusual
situation for temperature or voltage. No user
interaction required. If repeated after cooldown
and reboot, check if the ISM or cables around it are
defective.
0855E-0 ADM
WARNING Low elevation
The antenna is not allowed to transmit because the
elevation is too low. (!T)
0855F-0 ADM
WARNING Heading range
Heading data range error. External heading unit
supplies unreliable data.
08562-0 ADM
WARNING High elevation
The antenna cannot perform acquisition in gyro-
free mode because the elevation is too high.
08563-0 ADM
WARNING BCM warning
The BCM has observed an unusual situation with
regards to the PLL. If the situation persists, check
the BCM. (!T,!V)
08564-0 ADM
ERROR
BCM communication Communication error between PCM and BCM.
Check SUB-D connectors and cables. (!T,!V)
08565-0 ADM
ERROR
Deploy/Stow
Deploy/stow error. The antenna did not properly
unlock (deploy), or the stow switch never closed
(stow).
08566-0 ADM
ERROR
OMT error
Problem with OMT. Temperature out of range or
OMT cable may be broken.
08567-0 ADM
WARNING Automatic stow
The antenna automatically stowed because it
detected significant movement.
08568-0 ADM
WARNING Polarisation tuning
Polarisation tuning was not successful. Polarisation
may be incorrect.
08569-0 ADM
ERROR
BCM error
The BCM PLL failed to initialize.
0856A-0 ADM
WARNING Missing BUC response No response received from the BUC. (!T,!V,!S)
0856B-0 ADM
WARNING mpTRIA
communication
Communication from the mpTRIA has failed. (!G)
0856C-0 ADM
FATAL
Antenna base tilt
Antenna base tilted beyond limit.
0856D-0 ADM
WARNING VMU reference
distribution
VMU reference signal not present at BCM, but is
present at ACU. Check coax cable between VIM
and BCM. (!T,!V)
0856E-0 ADM
WARNING Antenna orientation The terminal is oriented in a way that prevents it
from pointing to the selected satellite.
08841-0 ADM
ERROR
Tuner lock
The internal tuner PLL was unable to lock. (!V,!T)
