5.6 Relay Scope of Functions (7800)

The numerous functions and optional features of the 7SA511 relay are indicated as existing or non-existing through address block 7800, Scope of Functions. This block is also used to identify the rated system frequency and choose the type of fault detection, pilot protection, and ground fault protection for the relay.

The parameters under this block identify the functions of the relay. Additional On/Off parameters under addresses within the 1000 to 4000 range are provided so you can manually switch functions on and off as needed. Section 5.17 discusses the On/Off parameters in more detail.

Table 5-3 identifies all of the relay functions controlled in address block 7800 along with the presettings and setting options. This table also refers you to the section in this chapter that describes the function in more detail, including the additional parameters required for the function to work. Only those functions available in your relay will appear in its display. Refer to your relay model number and to section 1.3, “Relay Model Number,” to verify which functions you should be able to control in address block 7800.

Compare these presettings to the information on the completed worksheets and determine which settings, if any, you need to change to match your operating environment. After all settings have been verified or changed appropriately, follow the procedure described in section 5.3.4 to save the new settings.
