8 - TROUBLESHOOTING & MAINTENANCE
Fault Code Description Detailed Description of Fault / Possible Solutions
F51 Current Sensor Offset Error Indicates that the MX
2
control card self-diagnostics have detected a
problem with one or more of the current sensor inputs.
Verify that the motor FLA (P1/QST01), CT ratio (P78/FUN03) and
burden switch settings are correct.
Verify that no actual current is flowing through any of the starter’s
CTs when the starter is not running.
Consult factory if fault persists.
F54 BIST Fault The starter has detected a voltage or a current. Remove line power
from input of starter. Disconnect must be open.
F55 BIST CT Fault Verify CT location, CT1 on L1, CT2 on L2, CT3 on L3. or CTs
are connected backwards (the polarity dot must be facing the supply
line).
F60 External Fault on DI#1 Input DI#1 has been programmed as a fault type digital input and the
input indicates a fault condition is present.
Verify that the appropriate Digital Input Configuration parameter
has been programmed correctly.
Verify wiring and level of input.
F61 External Fault on DI#2 Input DI#2 has been programmed as a fault type digital input and input
indicates a fault condition is present.
Verify that the appropriate Digital Input Configuration parameter
has been programmed correctly.
Verify wiring and level of input.
F62 External Fault on DI#3 input DI#3 input has been programmed as a fault type digital input and
input indicates a fault condition is present.
Verify that the appropriate Digital Input Configuration parameter
has been programmed correctly.
Verify wiring and level of input.
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 (P56/ I/O 09) for longer than the Analog Input Trip
Delay time (P57/ I/O 010).
Measure value of analog input to verify correct reading.
Verify settings of all Analog Input parameters
(P55-P59/ I/O 08- I/O 12).
Verify correct positioning of input switch (SW1)
(Voltage or Current) on the MX
2
control card.
Verify correct grounding of analog input connection to prevent
noise or ground loops from affecting input.
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
2
control card is powered up. Only connect and
disconnect a remote keypad when the control power is off).
Verify that the remote keypad cable has not been damaged and that
its connectors are firmly seated at both the keypad and the MX
2
control card.
Verify that the display interface card (when present) is firmly
attached to MX
2
control card.
Route keypad cables away from high power and/or high noise areas
to reduce possible electrical noise pickup.
