4 HUMAN INTERFACES
•
TROUBLE: This LED indicates that the relay has detected an internal problem.
•
TEST MODE: This LED indicates that the relay is in test mode.
•
TRIP: This LED indicates that the FlexLogic™ operand serving as a trip switch has operated. This indicator always
latches; as such, a reset command must be initiated to allow the latch to be reset.
•
ALARM: This LED indicates that the FlexLogic™ operand serving as an alarm switch has operated. This indicator is
never latched.
•
PICKUP: This LED indicates that an element is picked up. This indicator is never latched.
The event cause indicators in the first column are described below. These indicate the input type that was involved in a con-
dition detected by an element that is operated or has a latched flag waiting to be reset.
•
VOLTAGE: This LED indicates voltage was involved.
•
CURRENT: This LED indicates current was involved.
•
FREQUENCY: This LED indicates frequency was involved.
•
OTHER: This LED indicates a composite function was involved.
•
PHASE A: This LED indicates phase A was involved.
•
PHASE B: This LED indicates phase B was involved.
•
PHASE C: This LED indicates phase C was involved.
•
NEUTRAL/GROUND: This LED indicates that neutral or ground was involved.
The user-programmable LEDs consist of 48 amber LED indicators in four columns. The operation of these LEDs is user-
defined. Support for applying a customized label beside every LED is provided. Default labels are shipped in the label pack-
age of every F60, together with custom templates. The default labels can be replaced by user-printed labels.
User customization of LED operation is of maximum benefit in installations where languages other than English are used to
communicate with operators. Refer to the User-programmable LEDs section in chapter 5 for the settings used to program
the operation of the LEDs on these panels.
b) STANDARD FACEPLATE
The standar faceplate consists of three panels with LED indicators, keys, and a communications port. The RESET key is
used to reset any latched LED indicator or target message, once the condition has been cleared (these latched conditions
can also be reset via the
SETTINGS
to a portable PC.
The USER keys are used by the breaker control feature.
STATUS INDICATORS:
•
IN SERVICE: Indicates that control power is applied; all monitored inputs/outputs and internal systems are OK; the
relay has been programmed.
•
TROUBLE: Indicates that the relay has detected an internal problem.
•
TEST MODE: Indicates that the relay is in test mode.
