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)
