FAULTS

There are primarily two types of faults, faults that originate in the SiBas or the PLC. There are subclasses in each of these categories that are used for sorting purposes and display purposes

• Fault Classes

Fault classes are used primarily for the sorting function of the Fault system. Each class can contain one or more subclasses to allow a more detailed sort. There are 3 message classes used in this system.

• SiBas These faults are displayed in the fault system with a yellow background and black text. The SiBas class contains only faults generated by the SiBas. There is 1 subcategory, Alarm High.

• Alarms These faults are displayed in the fault system with a yellow background and black text. The Alarms class contains only ANF faults. There are 2 subclasses, Alarm High and Alarm Low.

• PLC Messages These faults are displayed in the fault system with a blue background and yellow text. This class contains only CDA faults. There are 2 subclasses, System and Error.

• Fault Numbering Convention

Fault numbers are derived from a combination of alpha characters and numeric values. The first three characters of any fault number are SIB, ANF or CDA. Faults generated by the SiBas have a prefix of SIB followed by three numbers. SiBas faults are numbered 1 through 999; leading zeros are always used.

ex: SIB021 SIB 021 ↑ ↑ SiBas Fault Fault 21

PLC faults are identified by the Prefix CDA and are numbered 1001 through 1299.

ex: CDA001 CDA 001 ↑ ↑ CDA Fault Fault 001
