If this alarm is configured to automatically reset under the setpoints for User Settings, the alarm clears itself
when the I-Peak condition clears.
If this alarm is set for manual reset mode, the alarm continues to show as active after the current returns to
nominal, still inhibiting transfers. You will need to manually reset the alarm. If configured to be a latching alarm,
