Fault Code Description Detailed Description of Fault / Possible Solutions
F10 Phase Rotation Error, not ABC
Input phase rotation is not ABC and Input Phase Sensitivity parameter (FUN 04)
is set to ABC only.
Verify correct phase rotation of input power. Correct wiring if necessary.
Verify correct setting of Input Phase Sensitivity parameter (FUN 04).
F11 Phase Rotation Error, not CBA
Input phase rotation is not CBA and Input Phase Sensitivity parameter (FUN 04)
is set to CBA only.
Verify correct phase rotation of input power. Correct wiring if necessary.
Verify correct setting of Input Phase Sensitivity parameter (FUN 04).
F12 Low Line Frequency
Line frequency below Under Freq Trip (PFN 15).
Verify input line frequency.
If operating on a generator, check generator speed governor for malfunctions.
Check input supply for open fuses or open connections.
Line power quality problem / excessive line distortion.
F13 High Line Frequency
Line frequency above Over Freq Trip (PFN 14).
Verify input line frequency.
If operating on a generator, check generator speed governor for malfunctions.
Line power quality problem / excessive line distortion.
F14 Input power not single phase
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.
Verify that the SCR gate wires are properly connected to the MX
3
control card.
F15 Input power not three phase
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
3
control card.
On medium voltage systems, verify wiring of the voltage feedback measurement
circuit.
F21 Low Line L1-L2
Low voltage below the Under voltage Trip Level parameter setting (PFN 11) was
detected for longer than the Over/Under Voltage Trip delay time (PFN 12).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN 05) is set correctly.
Check input supply for open fuses or open connections.
On medium voltage systems, verify wiring of the voltage measurement circuit.
F22 Low Line L2-L3
Low voltage below the Under voltage Trip Level parameter setting (PFN 11) was
detected for longer than the Over/Under Voltage Trip delay time (PFN 12).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN 05) is set correctly.
Check input supply for open fuses or open connections.
On medium voltage systems, verify wiring of the voltage feedback measurement
circuit.
F23 Low Line L3-L1
Low voltage below the Under voltage Trip Level parameter setting (PFN 11) was
detected for longer than the Over/Under Voltage Trip delay time (PFN 12).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN 05) is set correctly.
Check input supply for open fuses or open connections.
On medium voltage systems, verify wiring of the voltage feedback measurement
circuit.
