Instructions for the FP-6000 Protective Relay
Once the desired protection settings have been programmed, the
“Test” function can be used as follows:
•
If a non-trip test is desired, the user must disarm tripping. The
first step is to enable the “Disarm Control” setting in the “Set”
mode “System Config” setting menu. Then, the “Arm/Disarm
Trip” selection can be made from the test menu.
•
Press the “Test” button. Enter the unit’s password, then select
“Fault Simulation” under the test menu.
•
Enter the phasor values of voltages (line-to-neutral for a Wye
connection or line-to-line for a Delta connection) and phasor
currents. Refer to the FP-6000 protection settings to determine
appropriate values for testing. Select the “Fault V&I Phasors”
menu item and select the VA Phasor. Input the desired VA
magnitude from 0 to 150 V and the angle. Press “Enter” and
then press “Previous.” Repeat these steps to set the remaining
voltages and currents to the desired test values, then press
“Previous” to return to the “Fault Simulation” menu.
•
Using the down arrow key, select “Max Time (s):”. Enter the
maximum test time, in seconds (up to 600 seconds = 10
minutes), that the simulation will be allowed to run without a
trip condition.
•
Scroll down to the “Start Simulation!” menu selection. Press
“Enter” to begin the simulation.
•
Once the simulation is started and before a trip occurs, the
“Monitor” screens can be used to view the measured values
of the simulated voltages and currents.
•
When a trip occurs, the front panel “Log” screens can be used
to view the cause of the trip and the voltages, currents and
internal flags at the time of trip.
•
The time to trip can be viewed by reentering the front panel
“Test” function Fault Simulation/Stop Simulation, which
includes a screen showing the Simulation status, including the
elapsed time in cycles.
The power and energy calculations continue to be based on the
measured current and voltage inputs, not the simulation values.
The fault simulation is aborted and normal protection is resumed
if measured currents go above 0.1 per unit.
11.2.5.2 Operate Relays
Note that the Healthy Relay cannot be overwritten. To test the
Healthy Relay, cycle power and the contacts should follow. To
test relays 1 – 6, lift the protective cover labeled “Set” and “Test.”
Press the “Test” button. Enter the unit’s password, then scroll
down to “Operate Relays” using the single arrow down key. The
following procedure will test relay 3 in this example. Scroll down
using the single arrow key to “Operate Rly3” and press “Enter”,
then “Enter” once again to confirm. With an ohmmeter measure
between pins 113 and 114 of connector TB1 to verify that Relay 3
is closed. The resistance should be close to zero ohms. Now
press the “Previous” button to return to the test menu. Scroll
down to “Reset Relays” and press “Enter.” Scroll down using the
single down arrow key to “Reset Rly3.” Press “Enter” and
“Enter” again to confirm. Measure between pins 113 and 114 of
connector TB1 again. The ohmmeter should read a high
resistance or O.L. for an open circuit. This exercise can be
performed on all relays listed in the “Operate Relays” menu.
Note:
Trip 1 & 2 relays have approximately 44K across the open contacts
as part of the monitor circuit.
11.3 Cleaning Instructions
Never clean the FP-6000 with the system or FP-6000 power
energized. Clean only with a dry, clean cloth. Do not use water or
solvents of any kind.
11.4 Trip Battery Check
The battery backed trip circuit latch is sourced by a user-
accessible disc/button type battery located under the bottom
right hand communication cover which is shared with the
PowerPort RS232 interface. To test the battery simply push the
test button to the left of the battery holder with or without the
FP-6000 powered. If the green LED indicator, located above the
battery holder, does not light the batter has either expired or has
been installed incorrectly. The battery must be installed with the
positive side up (as shown on the front of the communication
cover) and the power must be ON. The battery can easily be
replaced with a 2032 (20 x 3.2 mm) 200 mAhr, 3.0 V lithium
button cell.
The battery must be installed while the FP-6000 is powered to
eliminate unnecessary wear on the battery. When power is
removed the battery maintains the trip status latch and drives the
appropriate LED. This will occur even with the inner case
removed from the outer chassis. A fresh battery should last a
minimum of 72 hours. If the battery is inserted while the power
is off it may remain in operation until it expires. This will cause
the battery to become useless if it is needed.
Note:
If the battery is inserted when the FP-6000’s power is off you may
notice one or all of the LEDs flashing. The LEDs will be restored to their
proper state when the power is turned ON, and in turn, will discontinue
the use of the battery.
11.5 Power-up LED Indicator Status
Upon power-up of the FP-6000, all 13 LEDs on the user interface
overlay and the four communication board LEDs viewed through
holes at the top of TB3 will light for ~ 1 second. If an LED fails to
light, this indicates there is an internal failure of the LED or
related circuitry, and the inner chassis is suspect and should be
replaced or returned for service. The Trip Battery test LED is a
separate circuit and does not light on power up, only when the
pushbutton is pushed.
