The following Warning Register sets a bit for every channel, which reads a current above the Warning
Threshold for at least the Warning Time-Delay� All warnings are latching and must be reset by the controller�
To reset any alarm, read the register and the write the register with the desired alarm bit cleared�

The following Warning Threshold register sets the thresholds for the Warning alarms� A Warning alarm is
given in percent of the Full load registers (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 Warning thresholds is 70%�
The Values that are written to the Warning Threshold must be between 40 and 100 and always below the
corresponding Alarm Threshold�
