8.4 Fault Code Table
The following is a list of possible faults that can be generated by the MX
2
SEP controller:
Fault Code Description Detailed Description of Fault / Possible Solutions
F01 Incomplete Sequence
Slip percentage (CFN 01 / P2) is set too low.
Incomplete Sequence Time (QST 03 / P6) is set too low.
F09 Loss of Synchronous
Slip percentage (CFN 01 / P2) is set too low.
Incomplete Sequence Time (QST 03 / P6) is set too low.
F12 Low Line Frequency
Line frequency below Setpoint (PFN11 / P29) was detected for longer than the
Freq Trip Time (PFN12 / P30).
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 Setpoint (PFN10 / P28) was detected for longer than the
Freq Trip Time (PFN12 / P30).
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 controller is expecting single-
phase power.
Verify that input power is single phase.
Verify that single-phase power is connected to the L1 and L3 inputs. Correct wiring
if necessary.
Verify that the SCR gate wires are properly connected to the MX2 SEP control
card.
F15 Input power not three phase
Single-phase power has been detected when the controller 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 MX2 SEP control
card.
F21 Low Line L1-L2
Low voltage below the Under voltage Trip Level parameter setting (PFN07 / P25)
was detected for longer than the Over/Under Voltage Trip delay time (PFN08 /
P26).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN06 / P23) is set correctly.
Check input supply for open fuses or open connections.
F22 Low Line L2-L3
Low voltage below the Under voltage Trip Level parameter setting (PFN07 P25)
was detected for longer than the Over/Under Voltage Trip delay time (PFN08 /
P26).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN06 / P23) is set correctly.
Check input supply for open fuses or open connections.
F23 Low Line L3-L1
Low voltage below the Under voltage Trip Level parameter setting (PFN07 / P25)
was detected for longer than the Over/Under Voltage Trip delay time (PFN08 /
P26).
Verify that the actual input voltage level is correct.
Verify that the Rated Voltage parameter (FUN06 / P23) is set correctly.
Check input supply for open fuses or open connections.
