4.4.3.
DC O
VERVOLTAGE
This fault indicates that the DC voltage on the bus has exceeded 1000V. This
fault latches until manually cleared.
4.4.4.
D
IFFERENTIAL
O
VERVOLTAGE
This fault indicates that the DC bus is more than 200V higher than the AC
line peak. This fault latches until manually cleared by toggling the Enable
Input.
4.4.5.
S
YNC
L
OSS
This fault indicates that the regen has lost synchronization with the AC line.
This fault will automatically clear if sync is reestablished, and will latch if it
cannot. If this fault recurs regularly or fails to clear, it is likely due to line
noise, a blown phase fuse, or an undersized AC source.
4.4.6.
IGBT D
RIVER
This fault indicates that the
unit’s internal transistor drive circuitry has
detected an error. This typically indicates an instantaneous overcurrent on
one of the AC legs. This fault will latch until cleared by toggling the Enable
Input. If this fault does not clear, it typically indicates that damage to the unit
has occurred.
4.4.7.
P
HASE
1-3 O
VERCURRENT
These faults indicate that the current the unit is regenerating into one leg of
the AC line has exceeded a safe operating level. This is likely due to voltage
distortion on the line. These faults will latch until cleared by toggling the
Enable Input.
4.4.8.
P
HASE
L
OSS
These faults indicate that the unit has lost voltage on one or more of the AC
line phases. These faults clear automatically when voltage is reestablished.
If these faults do not clear, it typically indicates that a line fuse has failed.
4.4.9.
DC U
NDERVOLTAGE
This fault indicates that the DC voltage on the bus is less than 100V. This
fault will clear automatically when the voltage rises to an operable level. If
this fault does not clear, it typically indicates that damage to the unit has
occurred.
