8 - TROUBLESHOOTING & MAINTENANCE
Fault Code Description Detailed Description of Fault / Possible Solutions
F60 External Fault on DI#1 Input
DI # 01 - 08 (I/O 01 - 08) has been programmed as a fault type digital input and
the input indicates a fault condition is present.
F61 External Fault on DI#2 Input
F62 External Fault on DI#3 input
F63 External Fault on DI#4 input
F64 External Fault on DI#5 input
F65 External Fault on DI#6 input
F66 External Fault on DI#7 input
F67 External Fault on DI#8 input
Increase Digital Fault Input Trip Time (I/O 09).
F71 Analog Input Level Fault Trip.
Based on the Analog Input parameter settings, the analog input level has either
exceeded or dropped below the Analog Input Trip Level setting ( I/O 17) for
longer than the Analog Input Trip Delay time (I/O 18).
Measure value of analog input to verify correct reading.
Verify settings of all Analog Input parameters ( I/O 16 - I/O 20 ).
Verify correct positioning of input switch (SW1-1) (Voltage or Current) on the
MX
3
control card.
Verify correct grounding of analog input connection to prevent noise or ground
loops from affecting input.
F80
RTD Module Communications
Fault
Communications with the RTD module(s) has been lost.
Verify RS-485 wiring between RTD module(s) and MX
3
card set.
Verify RTD module 24VDC power supply.
Verify that the RTD module(s) are set to the same address as the MX
3
module
address parameters RTD 01 and RTD 02.
F81 Keypad Communication Fault
Indicates that communication has been lost with the remote keypad.
(This fault normally occurs if the remote keypad is disconnected while the MX
3
control card is powered up.
Verify that the remote keypad cable has not been damaged and that its connectors
are firmly seated at both the keypad and the MX
3
control card.
Route keypad cables away from high power and/or high noise areas to reduce
possible electrical noise pickup.
F82 Modbus Timeout Fault
Indicates that the starter has lost serial communications. Fault occurs when the
starter has not received a valid serial communications within the Communication
Timeout parameter (FUN 18) defined time.
Verify communication parameter settings ( FUN 16 - FUN 19).
Check wiring between the remote network and the MX
3
control card.
Examine remote system for cause of communication loss.
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 (PFN 08) is turned "Off".
Verify that no current is flowing through the zero sequence ground fault CT.
Consult factory is fault persists.
