求翻译：设置仪表H1AL(上限报警)、IOAL(下限报警)可作为输入信号异常时报警输出，利用DHAL(正偏差报警)、DLAL(负偏差报警)可作为SV(阀位反馈信号)和PV(调节器输出信号)不一致时报警。是什么意思？

Set the meter H1AL (Cap alert), IOAL (lower limit alarm) can be used as the input signal alarm output when an exception, the use of DHAL (positive deviation alarm), DLAL (negative deviation alarm) can be used as SV (valve position feedback signals) and PV (regulator output signal) is not consistent

Settings 1 meter H AL (CAPs), IOAL (lower limit alarm alarm) can be used as input signal abnormalities DHAL alarm output, use (being bias (negative bias DLAL alarm), can be used as alarm) SV (valve feedback signals ( 70-75) and PV) are not consistent output signal alarm.
