User-programmable event-cause indicators
Event-cause LEDs are below the status LEDs. They are turned on or off by protection elements that have their respective
target setting selected as “Enabled” or “Latched.” If set to “Enabled,” then the corresponding event cause LED remains on
as long as the operand associated with the element remains asserted. If set to “Latched” and asserted, then it remains on
until the operand is reset and then a reset command initiated.
The LEDs have defaults and can be configured to show instead the status of any FlexLogic operand. The labelling area has
a clear cover behind which custom labels can be mounted. A utility is available to print stick-on labels, as outlined later in
this chapter.
These LEDs are programmed by default as follows:
• PICKUP — LED 6 — Indicates that an element is picked up, and hence a trip can be imminent
• VOLTAGE — LED 7 — Indicates voltage was involved
• CURRENT — LED 8 — Indicates current was involved
• ZONE 1 — LED 9 — Indicates bus differential zone 1 was involved
• ZONE 2 — LED 10 — Indicates bus differential zone 2 was involved
• ZONE 3 — LED 11 — Indicates bus differential zone 3 was involved
• ZONE 4 — LED 12 — Indicates bus differential zone 4 was involved
• ZONE 5 — LED 13 — Indicates bus differential zone 5 was involved
• ZONE 6 — LED 14 — Indicates bus differential zone 6 was involved
4.2.5 Front panel labelling
4.2.5.1 Enhanced front panel
The following procedure requires these pre-requisites:
• The UR front panel label cutout sheet (GE part number 1006-0047) has been downloaded from
http://www.gegridsolutions.com/products/support/ur/URLEDenhanced.doc
and printed
• Small-bladed knife
To create custom LED and pushbuttons labels for the enhanced front panel:
1. Start the EnerVista UR Setup software.
2. If not already copied to the Offline Window area, right-click the online device and select the Add Device to Offline
Window option. Click the Receive button in the window that opens to save the settings file to the Offline Window area.
3. Type labels as follows. Select the File > Front Panel Report. The window opens.
