Instructions for the FP-6000 Protective Relay
12.1.4 Self Test Failure Indication
When a diagnostic self test indicates a failure, an error message
is displayed instead of the default metering display, and the
Healthy Relay (K7) is de-energized, no longer indicating proper
operation. All other display screens operate normally to permit
display of diagnostic information during troubleshooting. The
screen saver is disabled when a warning or failure message is
displayed. If more than one warning or failure condition exists,
the FP-6000 scrolls through the multiple error messages. Table
57, under the “Display” column, shows all possible displays. A group of status flags are given in the Status/Control mode that
describes the current results of diagnostic self tests. To view
these status flags press the Status/Control button, select
“Status” and press enter, select “Self Test Status” and press
enter, use the arrow keys to scroll through the list. Table 57,
under the “Status Flag” column, lists all of the self test status
flags.

DISPLAY STATUS FLAG PROTECTION DESCRIPTION RECOMMENDED ACTION
Boot Code CheckSum Error Boot Code Disabled The boot code firmware has been
corrupted. The circuit is not protected, replace
FP-6000 immediately Possible Flash reload.
Application Code Check sum
Error Firmware Disabled The application code firmware has been
corrupted. The circuit is not protected, replace
FP-6000 immediately Possible Flash FW reload.
RAM Failure at 0X——- External RAM Disabled A portion of external RAM cannot be read
or written. The circuit is not protected, replace
FP-6000 immediately.
RAM Failure at 0X——- Internal RAM Disabled A portion of the RAM internal to the micro-
processor cannot be read or written. The circuit is not protected, replace
FP-6000 immediately.
Protection Disabled Analog
Input Failure Analog Input Disabled The analog inpu has failed to respond or
has read a reference input incorrectly. The circuit is not protected, replace
FP-6000 immediately.
Protection Disabled Setting
Failure Settings Disabled If Fail, the setpoints have been corrupted. The circuit is not protected, replace
FP-6000 immediately.
Display Warning Display Enabled The display content could not be verified. Replace FP-6000 at the earliest convenience.
Protection Disabled Relay Not
Calibrated Calibrated Disabled At power up, the calibration constants
are corrupted. The circuit is not protected, replace
FP-6000 immediately.
Nonvolatile Memory Battery
Warning RAM Battery Enabled The NVRAM battery is failing. If needed, store all log and history data before
power down. This can be done with the PowerNet
application software. Contact factory for replace-
ment instructions.
Real-Time Clock Warning Clock Enabled The real time clock has malfunctioned. Check the clock for proper time and future time
keeping. If in error, replace at the earliest
convenience.
EEPROM Warning EEPROM Enabled The EEPROM cannot be read or written. Replace the FP-6000 at the earliest convenience. It
is possible that the FP-6000 will fail to protect the
circuit the next time powered up.
Protection Disabled Calibrate
Failure Calibration Disabled The calibration constants have been cor-
rupted. The circuit is not protected, replace
FP-6000 immediately.
Setting Warning — Enabled A recoverable corruption of the setpoints
has occurred. Check the settings in the FP-6000, making correc-
tions if needed. If this warning repeats then
replace the FP-6000.
Test in Progress — Disabled A test simulation has begun. To stop the test, press the Test button, select Fault
Simulation, and select Stop Simulation.
Calibrate Warning — Enabled A recoverable corruption of the calibration
setpoints has occurred. Check the accuracy of the voltage current input
measurement. If this warning repeats then replace
the FP-6000.
EEPROM Write Warning — Enabled The EEPROM has been written to a large
number of times and is in danger of
wearing out. Call the factory, for troubleshooting help.
EEPROM Write Lockout — Enabled Because the EEPROM has been written to a
large number of times no more writes are
permitted. Call the factory, for troubleshooting help.
Relay Tripping Disarmed — Disabled The Disarmed function has been activated. The Disarmed feature can be turned off by
pressing the “Test” pushbutton selecting Arm/Dis-
arm Trip, and selecting Arm Trip.
