5.4.13 LED Configuration Settings
There are 12 LEDs out of 15 LEDs that are made programmable in
the FP-6000. Among those, four are dedicated to Phase Trip,
Ground Trip, Alarm, and Pickup. The other eight LEDs are made
programmable through the use of the programmable logic gate
mechanisms. The four dedicated LEDs are configured through
three indicators: Trip, Alarm, and Pickup. These indicators are
simple OR gates. The programmable LEDs are located under the
Status pushbutton and vertically distributed in order. In addition,
the LED 1 and 2 are in green, the LED 3 to 6 in yellow, and the
LED 7 and 8 in red.
Trip Indicator
The trip indicator function reports the presence of a trip
condition. This setting is programmed to operate based upon the
operation of the output relays (Trip1, Trip2, Rly3, Rly4, Rly5,
Alarm, and Healthy). This setting consists of the settings below.
Dropout:
Set to Latched or Unlatched. This setting determines if the trip
indicator stays active after a trip event clears.
Latched setting means that the Trip Indicator and the appropriate
trip indicator LED lights on the front panel will stay latched until a
“Reset” is initiated either manually or remotely.
Unlatched setting means that the state of the Trip Indicator
directly follows the state of the associated output relay.
Trip1:
Set to enable or disable.
Trip2:
Set to enable or disable.
Rly3:
Set to enable or disable.
Rly4:
Set to enable or disable.
Rly5:
Set to enable or disable.
Alarm:
Set to enable or disable.
Healthy: Set to enable or disable. The indicator is active when
the Healthy Alarm is de-energized to report a failure.
The default configuration sets the Dropout to “Latched” and
enables the Trip Indication when Trip1 or Trip2 output relays are
energized.
Alarm Indicator
The Alarm indicator function reports the presence of an
alarm condition.
This function is set the same way as the Trip
Indicator. See Trip Indicator settings above. The default
configuration sets the Dropout to Latched and enables the Alarm
Indication when the Alarm Output relay is energized or the Relay
Healthy output relay is de-energized.
Pickup Indicator
The Pickup Indication function reports a pickup of the
programmed protective functions. The pickup indicator is active
for the protective functions that are enabled in the settings.
Dropout:
Set to Latched or Unlatched. This setting determines if the pickup
indicator stays active after a pickup event. This Dropout setting
works exactly the same as the Dropout setting in the Trip
Indicator settings shown above.
IOC:
Set to enable or disable.
TOC:
Set to enable or disable.
Volt:
Set to enable or disable.
OverFreq:
Set to enable or disable.
UnderFreq:
Set to enable or disable.
Unbalance:
Set to enable or disable.
Prot Alarm:
Set to enable or disable.
Power:
Set to enable or disable.
RTD:
Set to enable or disable.
The default configuration sets the Dropout to Unlatched and
enables all protective functions except the Prot Alarm setting.
Programmable LED Configuration Settings (LED Config)
These settings are used to configure the programmable LED 1 to
8 logic gates, whose outputs are used to determine the states of
the LED 1 to 8. Each the programmable LED contains the
settings:
•
Function
•
Dropout
•
IN1
•
IN2
•
IN3
•
IN4
These are set in a similar way to other programmable logic gates
except they have one extra input option category to choose: the
Display Mode.
