The fault code is a number up to five digits in length that, along with the fault code
description, helps the Capstone Authorized Service Provider determine the cause of the
incident. Some fault codes can be useful to the operator, as they indicate common
conditions that can occur in system. Table 7 shows a list of common protective relay
faults. Utility grid events such as these will cause the Hybrid UPS systems to go into
Emergency Mode.
