Overview; System Settings - NR Electric PCS-9611 Instruction Manual

7.1 Overview

The settings are used to determine the characteristic of each protective element and operation
mode of the relay. It is necessary to configure the settings of this relay according to engineering
demands before putting this relay into service. If the settings are not configured correctly, this
relay maybe works abnormally (such as communication interruption, printing out unexpected
codes etc.), it also can lead to much more serious accident (such as unwanted operation, missing
operation) sometimes.
The settings of this relay include system settings, protection settings, communication settings and
miscellaneous settings. The user can configure these settings or parameters manually (see
Section 8.2.6.2). Remote modification is also supported (IEC61850, IEC60870-5-103 or DNP3.0
interface, see Chapter 10 for the details about these protocols).
NOTE! If a CPU module is replaced, it is necessary to configure all the settings again
according to the configuration of the CPU module which is replaced.

7.2 System Settings

The system settings (in the submenu "System Settings") are mainly used to set the rated value
of VT and CT.
