Fault Code Description Detailed Description of Fault / Possible Solutions
F84
MX
3
to I/O Card Communication
Fault (Interboard fault)
Communication between the two MX
3
cards has been lost.
Verify that both cards are mounted together and that the mounting hardware is not
loose.
Verify that no foreign matter is located between the two boards.
Consult factory if fault persists.
F85 I/O Card SW version Fault
Typically occurs when attempting to run a version of application software that is
incompatible with the bottom I/O card. Verify that the software is a correct
version for the I/O card being used. Consult factory for more details.
F86 I/O Card Current Offset Error
Indicates that the I/O card self-diagnostics have detected a problem with the zero
sequence ground fault input.
If no zero sequence ground fault CT is connected to input, verify that parameters
ZS GF Lvl (PFN08) is turned "Off".
Verify that no current is flowing through the zero sequence ground fault CT.
Consult factory is fault persists.
F87 I/O Card Error
I/O card has detected a problem with the Real Time Clock operation. Consult
factory.
F88 I/O Card Error I/O card has detected an internal CPU problem. Consult factory.
F89 I/O Card SW Watchdog I/O card has detected an internal software problem. Consult factory.
F90 I/O Card Error I/O card has detected an internal CPU problem. Consult factory.
F91
I/O Card Program EPROM
Checksum
I/O card has detected an internal CPU problem. Consult factory.
F94 CPU Error – SW Fault
Typically occurs when attempting to run a version of control software that is
incompatible with the MX
3
control card hardware being used. Verify that the
software is a correct version for the MX
3
control card being used. Consult factory
for more details.
Fault can also occur if the MX
3
control has detected an internal software problem.
Consult factory.
F95
CPU Error – Parameter EEPROM
Checksum Fault
The MX
3
found the non-volatile parameter values to be corrupted. Typically
occurs when the MX
3
is re-flashed with new software.
Perform a Factory Parameter reset and then properly set all parameters before
resuming normal operation.
If fault persists after performing a Factory Parameter reset, consult factory.
F96 CPU Error The MX
3
has detected an internal CPU problem. Consult factory.
F97 CPU Error – SW Watchdog Fault The MX
3
has detected an internal software problem. Consult factory.
F98 CPU Error The MX
3
has detected an internal CPU problem. Consult factory.
F99
CPU Error – Program EPROM
Checksum Fault
The non-volatile program memory has been corrupted.
Consult factory. Control software must be reloaded in to the MX
3
control card
before normal operation can resume.
