10-6 Appendix 10: System messages 98-148247-C
0A059-0 Antenna WARNING Azi cal. limits Check limits of the calibration result for the azimuth
axis are exceeded. Pointing performance may be
degraded. Info:
0x00000040: End stop detected before expected
limit
0x00000100: Zero width is low
0x00000200: Zero width is high
0x00000400: Zero slack is high
0x00001000: Friction average is high
0x00002000: Friction peak is high
0x00004000: Friction asymmetry is high Zero width
low/high: Zero reference module placement may be
incorrect. Zero slack high: Mechanical slack may be
too high. Friction average/peak high: Mechanical
friction is higher than expected. Friction asymmetry
high: Mechanical imbalance may be too high.
0A05A-0 Antenna WARNING Xel cal. limits Check limits of the calibration result for the cross-
elevation axis are exceeded. Pointing performance
may be degraded. Info: See 0A059-0.
0A05B-0 Antenna WARNING Ele cal. limits Check limits of the calibration result for the elevation
axis are exceeded. Pointing performance may be
degraded. Info: See 0A059-0.
0A05D-0 Antenna 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.
0A05E-0 Antenna WARNING Low elevation The antenna is not allowed to transmit because the
elevation is too low.
0A05F-0 Antenna WARNING Heading range Heading data range error. External heading unit
supplies unreliable data.
0A062-0 Antenna WARNING High elevation The antenna cannot perform acquisition in gyro-free
mode because the elevation is too high.
0A063-0 Antenna WARNING BCM warning The BCM has observed an unusual situation with
regards to the PLL. If the situation persists, check the
BCM.
0A064-0 Antenna ERROR BCM communication Communication error between PCM and BCM. Check
SUB-D connectors and cables.
0A065-0 Antenna ERROR Deploy/Stow Deploy/stow error. The antenna did not properly
unlock (deploy), or the stow switch never closed
(stow).
