Fault Code Description Detailed Description of Fault / Possible Solutions
Three-phase power has been detected when the starter is expecting single-
phase power.
Verify that input power is single phase.
Verify that single-phase power is connected to the L1 and L2 inputs.
Correct wiring if necessary.
F14 Input power not single
phase
Verify that the SCR gate wires are properly connected to the MX control
card.
Single-phase power has been detected when the starter is expecting three-
phase power.
Verify that input power is three phase. Correct wiring if necessary.
Verify that the SCR gate wires are properly connected to the MX control
card.
F15 Input power not three
phase
On medium voltage systems, verify wiring of the voltage feedback
measurement circuit.
Low voltage below the Undervoltage Trip Level parameter setting
(P31/PFN08) was detected for longer than the Over/Under Voltage Trip
delay time (P32/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P66/FUN05) is set correctly.
Check input supply for open fuses or open connections.
F21 Low Line L1-L2
On medium voltage systems, verify wiring of the voltage measurement
circuit.
Low voltage below the Undervoltage Trip Level parameter setting
(P31/PFN08) was detected for longer than the Over/Under Voltage Trip
delay time (P32/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P66/FUN05) is set correctly.
Check input supply for open fuses or open connections.
F22 Low Line L2-L3
On medium voltage systems, verify wiring of the voltage feedback
measurement circuit.
Low voltage below the Undervoltage Trip Level parameter setting
(P31/PFN08) was detected for longer than the Over/Under Voltage Trip
delay time (P32/PFN09).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (P66/FUN05) is set correctly.
Check input supply for open fuses or open connections.
F23 Low Line L3-L1
On medium voltage systems, verify wiring of the voltage feedback
measurement circuit.
High voltage above the Over voltage Trip Level parameter setting
(P30/PFN07) was detected for longer than the Over/Under Voltage Trip
delay time (P32/PFN09).
Verify that the actual input voltage level is correct.
F24 High Line L1-L2
Verify that the Rated Voltage parameter (P66/FUN05) is set correctly.
Line power quality problems/ excessive line distortions.
