All of the alarms listed in Table 5-5 can be reset via the Target/Alarm Reset by pushing “C” on the MMI twice or by the Miscellaneous Command Menu in ECP.
Warning: If the counter exceeds the threshold setting and the alarms are reset, the alarms exceeding the threshold setting will be reactivated at the time of the next fault.
The Phase Demand Alarm (PDA) and the Neutral Demand Alarm (NDA) will reset when current drops to 98% of threshold setting.
