All alarms are active until reset by the controller, or the current returns to the channel� To reset any alarm,
read the register and then write the register with the desired alarm bit cleared�
Note: Current Loss is when the current goes above 1�5 Amps and then goes to zero an alarm is set for that
branch breaker� If bit 15 on the Current Option Setting is set the alarm will be active on the loss of current�

The following Warning Threshold register sets the thresholds for the Warning alarms� A Warning alarm
is given in percent of the breaker size registers for each phase (75 = 75%)� A Warning alarm will occur if
the measured current is above the Warning Threshold for at least the Warning Time Delay� Default for the

100 and always below the corresponding Alarm Threshold�
