| Alarm monitoring item when mounting PA2S32/PA2S37 | |
| Power failure | Each DC voltage of power supply part is observed and warning is output by the change of ±20% or more. |
| Output abnormal | When the output becomes following the setting, warning is output. |
| PA abnormal | Each FET current are observed and When it changes to -30% or less of idol (current at a no signal), or to +30% or more of the current outputs ratings, the FET current is intercepted; warning is output, and maintained. |
| FAN abnormal | When fan is stopping, or becoming 700mi-1n or less (designed value), warning is output. |
| Temperature abnormal | When the FET temperature becomes +85°C, the FET current is intercepted; warning is output, and maintained. |
