Fault Code Description Detailed Description of Fault / Possible Solutions
F24 High Line L1-L2 High voltage above the Over voltage Trip Level parameter setting
(P35/PFN07) was detected for longer than the Over/Under Voltage
Trip delay time (P40/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P76/FUN05) is set
correctly.
Line power quality problems/ excessive line distortions.
F25 High Line L2-L3 High voltage above the Over voltage Trip Level parameter setting
(P38/PFN07) was detected for longer than the Over/Under Voltage
Trip delay time (P40/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P76/FUN05) is set
correctly.
Line power quality problems/ excessive line distortions.
F26 High Line L3-L1 High voltage above the Over voltage Trip Level parameter setting
(P38/PFN07) was detected for longer than the Over/Under Voltage
Trip delay time (P40/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P76/FUN05) is set
correctly.
Line power quality problems/ excessive line distortions.
F27 Phase Loss The MX
2
has detected the loss of one or more input or output
phases when the starter was running. Can also be caused by line
power dropouts.
Check input supply for open fuses.
Check power supply wiring for open or intermittent connections.
Check motor wiring for open or intermittent connections.
On medium voltage systems, verify wiring of the voltage feedback
measurement circuit.
Check Gate and Cathode connections to MX
2
card.
F28 No Line No input voltage was detected for longer than the Inline
Configuration time delay parameter setting (P63/ I/O16) when a
start command was given to the starter.
If an inline contactor is being used, verify that the setting of the
Inline Configuration time delay parameter (P53/ I/O16) allows
enough time for the inline contactor to completely close.
Check input supply for open disconnects, open fuses, open circuit
breakers or disconnected wiring.
Verify that the SCR gate wires are properly connected to the MX
2
control card.
On medium voltage systems, verify wiring of the voltage feedback
measurement circuit.
