Instructions for the FP-6000 Protective Relay
7 Startup
General — This section lists the procedure for applying power to
an FP-6000 for the first time. Use it as a checklist to reduce the
chance of skipping an item.
Startup consists of programming the necessary operational
parameters, verifying the operation of the FP-6000, checking the
wiring, and verifying the reasonable operation of the system
components before attempting to place the equipment into
continuous service.
The programming should already be done before FP-6000 is
placed into service. Protection parameters may be reviewed in
the View Settings mode or adjusted in the Set Mode.
Refer to wiring Figures 4 and 5 and Figure 31 on terminal
definitions, Section 3 - Specifications for nominal ratings during
startup.
7.1 Power-Off Checks
With the incoming ac distribution power locked off and after all
sources of power to the FP-6000 are de-energized, including
control system battery, check the wiring for conformance to the
wiring plan developed for the application.
•
Verify that the CT secondary current rating and the FP-6000 CT
input rating style agree (either 5 A or 1 A). See Section 1.8 -
Ordering Information for catalog number identification.
•
Verify that the voltage Inputs are referenced to voltage
transformers where the common is earth ground. TB2 terminal
218 “Vg” is internally bonded within the FP-6000 to protective
earth and can not be connected to neutral or a phase
reference.
7.2 Initial Control Power-On Checks
•
All power sources should be disconnected as described in
Section 7.1.
•
Disable all trip and control circuits.
•
Disconnect and insulate the breaker trip coil load leads from
any of the trip relay terminals, typically Relay 1 and Relay 2 on
TB1 terminals 116 and 118, to prevent breaker from energizing
during most of this testing.
•
Disconnect and insulate any control circuit loads connected to
the remaining control relays on the FP-6000.
•
Verify FP-6000 power supply control power:
– Disconnect the ac or dc control power lead to terminals
TB101(+).
– Connect a voltmeter to the circuit that fed TB101 and the
return on TB102.
– Energize the FP-6000 power supply power source
and monitor the voltage.
– Make sure that it is within nominal specifications:
– Battery system 48 – 125 Vdc or
control power transformer 100 – 120 Vac.
– De-energize the power supply source.
– For 250 Vdc power supply board, nominal ranges:
100 to 240 Vac or 100 to 250 Vdc
•
Verify trip relay control voltage:
– Connect a voltmeter between each trip relay breaker trip
coil load wire just disconnected from terminal 116 or 118,
and the other meter lead to the control power source
(TB115/117).
– Energize the trip coil source power.
– Measure the voltage and ensure that it is within the
FP-6000 trip relay nominal specifications.
– De-energize the control power and troubleshoot
as necessary.
•
Verify the FP-6000 Relay Health Alarm, Breaker Alarm, and any
other auxiliary FP-6000 relay control circuit in the same
manner as the trip relay circuits.
7.3 Check with FP-6000 Powered
•
All relay loads should remain disconnected.
•
Reconnect the FP-6000 power supply connection TB101 and
energize the source.
•
The FP-6000 should initialize and display the default Metering
Screen, the operational LED should be blinking at 1 Hz.
•
Examine the Self-Test flags by navigating to the status/control
mode and select Self-Test. Refer to Section 12.1.4 Self Test
Failure Indication for detailed description and possible action.
•
If previously programmed, then the setpoints should be
verified against a system drawing for this application:
– Section 5 can aid in understanding the setpoint configura-
tion.
– Note that PowerNet or PowerPort PC software can be used
to record setpoint files.
– Confirm that correct active setting group is selected.
DANGER
ONLY QUALIFIED PERSONNEL FAMILIAR WITH THE FP-6000, THE
BREAKER, AND ITS ASSOCIATED MECHANICAL EQUIPMENT,
SHOULD PERFORM THESE STARTUP PROCEDURES. FAILURE TO
COMPLY CAN RESULT IN SERIOUS OR FATAL INJURY AND/OR
EQUIPMENT DAMAGE.
CAUTION
NEVER HIGH POT THE FP-6000 CIRCUITS BEYOND 1500 VRMS/
1 MIN. DO NOT USE A MEGGER
®
, HI-POT, OR OTHER HIGH VOLT-
AGE INSULATION TESTER ON THE FP-6000 TERMINALS, IT HAS
BEEN FACTORY TESTED, AND FIELD TESTING MAY CAUSE UNNEC-
ESSARY STRESS. REMOVE THE FP-6000 INNER CHASSIS WHEN
TESTING THE PROTECTIVE RELAY SYSTEM.
CAUTION
DO NOT USE A MEGGER
®
, HI-POT, OR OTHERWISE HIGH VOLTAGE
TO TEST THE FOLLOWING TERMINALS OR POINTS:
•
TB3 - J1-3 SHIELD – IS BONDED TO HOUSING
(FILTER CLAMP)
•
TB3 - J2-3 SHIELD – IS BONDED TO HOUSING
(FILTER CLAMP)
•
TB3 - J3-5 SHIELD – IS BONDED TO HOUSING
(DIRECT GROUND)
•

(FILTER CLAMP)
•
FRONT RS-232 PROGRAMMING PORT SHELL – IS BONDED TO
HOUSING (DIRECT GROUND).
WARNING
VOLTAGE TRANSFORMERS ARE OFTEN CONNECTED “UPSTREAM”
FROM THE BREAKER CIRCUIT MONITORED AND SO MAY BE DIFFI-
CULT TO DISENGAGE.
