Figure 3 Menu structure
The settings in the menu are in three categories: Protection settings, disturbance recorder
settings, or control and support (C&S) settings.
New control and support settings are stored and used by the relay immediately after they are
entered. New Group settings or disturbance recorder settings are stored in a temporary
‘scratchpad’. Once the new settings have been confirmed, the relay activates all the new
settings together. This provides extra security so that several setting changes made in the
Group settings all take effect at the same time.
1.5.1 Protection settings
The protectio
n settings include the following items:
 Protection element settings
 Scheme logic settings
There are four groups of protection settings, with each group containing the same setting
cells. One group of protection settings is selected as the active group, and is used by the
protection elements.
1.5.2 Disturbance recorder settings
The distu
rbance recorder settings include the record duration and trigger position, selection
of analog and digital signals to record, and the signal sources that trigger the recording.
1.5.3 Control and support settings
The co
ntrol and support settings include:
 Relay configuration settings
 VT ratio settings
 Reset LEDs
 Active protection setting group
 Password & language settings
