Description Corrective Action
ADCCALER Internal calibration signal in the HLAI
is off by more than ± 5%. Replace the HLAI IOP card.
ADCINCMP A/D conversion incomplete. Replace the HLAI IOP card.
ADOUTOVF Not applicable
ADOUTUDF A/D reference point conversion value
≤ zero. Replace the HLAI IOP card.
BADDARNG AO IOP card DAC load value is NAN
or +INF or -INF. Replace the AO IOP card.
BADDCLTC AO card detected that DAC IOP card
interface latch was bad. Replace the AO IOP card.
