( 1 ) Resettable shutdown faults are reset by selecting parameter :96 (shutdown fault reset) on the display and pressing the function key or with the fault reset switch (external attachment) or through J1 connector. Non-resettable shutdown faults are reset by powering down the digital voltage regulator (removing 24 VDC).
( 2 ) The digital voltage regulator looks for 0.4 and greater leading power factor for shutdown.

Alarm Faults (Parameter :95)    
Fault
Code    Description    Classification (1)    
0000     No Fault Present     -    
601     Internal Memory Failure     Alarm Fault    
602     Internal Watchdog Failure     Alarm Fault    
603     Rotating Diode Fault     Alarm Fault    
604     Reverse VAR (2) (3)     Alarm Fault    
( 1 ) Alarm faults are cleared by selecting parameter :94 (fault clear) on the display and pressing the function key.
( 2 ) The digital voltage regulator looks for 0.4 and greater leading power factor for shutdown.
( 3 ) Available only on part numbers 155-xxxx and newer.Each fault is assigned a unique three digit code that is called the fault code. Fault codes are the values of parameter :92. Parameter :92 shows the latest fault.Note: An additional fault (fault code 901) exists. Fault code 901 indicates a significant failure of the internal memory that stores current parameter data. This fault can only occur at power-up and when making changes to configurable parameter values. This is a shutdown fault, and the digital voltage regulator will prohibit power generation. Fault code 901 is classified as a severe fault. This fault code can not be reset. Therefore, the digital voltage regulator must be replaced.Note: Parameter :95 only appears on the earlier digital voltage regulator. Parameter :95 shows an alarm fault. See System Operation, "Parameters" in order to determine the serial number break.A fault is a condition that does not conform (an abnormal condition) to the rules (program) by which the digital voltage regulator operates. Some examples of a fault are listed below.Undervoltage - Generator voltage is less than specified for too long a time.Overexcitation - The measured field current is too high for too long a time.When a fault occurs, the digital voltage regulator automatically flashes the corresponding fault code on the display and takes the necessary preventive action. For shutdown faults, the digital voltage regulator disables the output to the exciter. While a fault is present, the fault code information shown on the
