Troubleshooting

Table 19 contains descriptions of non-critical alarm messages. Non-critical alarms are not as urgent as critical alarms, but should be attended to as soon as convenient to avoid the problem becoming critical.

See Table 9 on page 67 and Table 20 on page 86 for information about reason codes. Contact your service representative.

Low Redundancy (U) The number of active power modules is too low to provide the programmed redundancy level to protect the current load.

The unit is able to protect the equipment, but will not be fault tolerant. To regain the desired redundancy, either add power modules or reduce the load. See Table 9 on page 67 and Table 20 on page 86 for information about reason codes.
