DESCRIPTION OF PROBLEM HOW OFTEN THE
TEST IS PERFORMED
WHAT TO DO
DSP ERRORS:
A/D Calibration, A/D
Interrupt, A/D Reset, Inter
DSP Rx, Sample Int, Rx
Interrupt, Tx Interrupt, Rx
Sample Index, Invalid
Settings, Rx Checksum
Yes CT/VT module with digital signal
processor may have a problem.
Every 1/8th of a cycle. Cycle the control power (if the problem
recurs, contact the factory).
DSP ERROR:
INVALID REVISION
Yes One or more DSP modules in a
multiple DSP unit has Rev. C
hardware
Rev. C DSP needs to be replaced
with a Rev. D DSP.
Contact the factory
EQUIPMENT MISMATCH
with 2nd-line detail
No Configuration of modules does not
match the order code stored in the
CPU.
On power up; thereafter, the
backplane is checked for missing
cards every 5 seconds.
Check all modules against the order
code, ensure they are inserted
properly, and cycle control power (if
problem persists, contact factory).
FLEXLOGIC ERR TOKEN
with 2nd-line detail
No FlexLogic™ equations do not
compile properly.
Event driven; whenever Flex-
Logic™ equations are modified.
Finish all equation editing and use self
test to debug any errors.
LATCHING OUTPUT
ERROR
No Discrepancy in the position of a
latching contact between firmware
and hardware has been detected.
Every 1/8th of a cycle. The latching output module failed.
Replace the Module.
PROGRAM MEMORY
Test Failed
Yes Error was found while checking
Flash memory.
Once flash is uploaded with new
firmware.
Contact the factory.
UNIT NOT CALIBRATED No Settings indicate the unit is not
calibrated.
On power up. Contact the factory.
UNIT NOT PROGRAMMED No PRODUCT SETUP
INSTALLATION setting indicates
relay is not in a programmed state.
On power up and whenever the
RELAY PROGRAMMED setting is
altered.
Program all settings (especially those
under PRODUCT SETUP
INSTALLATION ).

TARGET
MESSAGE
DESCRIPTION OF PROBLEM HOW OFTEN THE
TEST IS PERFORMED
WHAT TO DO
BATTERY FAIL Yes Battery is not functioning. Monitored every 5 seconds. Reported
after 1 minute if problem persists.
Replace the battery located in the
power supply module (1H or 1L).
DIRECT RING BREAK No Direct input/output settings
configured for a ring, but the
connection is not in a ring.
Every second. Check direct input/output configuration
and/or wiring.
DIRECT DEVICE OFF No A direct device is configured but
not connected.
Every second. Check direct input/output configuration
and/or wiring.
EEPROM DATA
ERROR
Yes The non-volatile memory has been
corrupted.
On power up only. If this message appears after an order
code update is preformed, press the
RESET key to clear target message. In
other cases, contact the factory.
IRIG-B FAILURE No A bad IRIG-B input signal has been
detected
Monitored whenever an IRIG-B signal
is received.
Ensure the IRIG-B cable is connected,
check cable functionality (i.e. look for
physical damage or perform continuity
test), ensure IRIG-B receiver is
functioning, and check input signal level
(it may be less than specification). If
none of these apply, contact the factory.
LATCHING OUT
ERROR
Yes Latching output failure. Event driven. Contact the factory.
LOW ON MEMORY Yes Memory is close to 100% capacity. Monitored every 5 seconds. Contact the factory.
PRI ETHERNET FAIL Yes Primary Ethernet connection failed. Monitored every 2 seconds Check connections.
PROTOTYPE
FIRMWARE
Yes A prototype version of the firmware
is loaded.
On power up only. Contact the factory.
REMOTE DEVICE OFF No One or more GOOSE devices are
not responding.
Event driven – occurs when a device
programmed to receive GOOSE
messages stops receiving. Every 1 to
60 s, depending on GOOSE packets.
Check GOOSE setup.
SEC ETHERNET FAIL Yes Sec. Ethernet connection failed. Monitored every 2 seconds Check connections.
SNTP FAILURE No SNTP server not responding. 10 to 60 seconds. Check SNTP configuration and/or
network connections.
SYSTEM EXCEPTION Yes Abnormal restart from modules
being removed/inserted when
powered-up, abnormal DC supply,
or internal relay failure.
Event driven. Contact the factory.
WATCHDOG ERROR No Some tasks are behind schedule. Event driven. Contact the factory.
