11348 C1 Line Fuse L1
C2 Line Fuse L1
C3 Line Fuse L1 Non-Reset
Fault Coast The line fuse for Line n has blown.
• Check the fuse and replace if necessary.
• Verify that the line fuse wiring harness for line 1 is not damaged and
is connected to P7 on the converter gate firing board. Replace the
wiring harness if necessary.
• If this problem persists, replace the converter gate firing board.

C2 BFuse Harness
C3 BFuse Harness Non-Reset
Fault Coast A bus fuse wiring harness connection loss has been detected.
• Check the bus fuse harness and replace if necessary.
• If this problem persists, replace the converter gate firing board.

C2 BFuse Pos
C3 BFuse Pos Non-Reset
Fault Coast The DC+ bus fuse is blown.
• Check the DC+ bus fuse and wiring harness and replace if necessary.
• If this problem persists, replace the converter gate firing board.

11359 C1 BFuse Neg
C2 BFuse Neg
C3 BFuse Neg Non-Reset
Fault Coast The DC- bus fuse is blown.
• Check the DC- bus fuse and wiring harness and replace if necessary.
• If this problem persists, replace the converter gate firing board.

11360 C1 Command Stop
C2 Command Stop
C3 Command Stop Resettable
Fault Coast Y The main control board has commanded the converter gate firing board
to stop due to an asymmetrical bus condition.
• Check the DC bus connections and wiring.

11361 C1 AC Line High
C2 AC Line High
C3 AC Line High Resettable
Fault Coast The AC line voltage has exceeded 565V (for 400V class drives) or 815V
(for 600V class drives), which corresponds to the nominal bus voltage of
799V DC (for 400V class drives) or 1150V DC (for 600V class drives). This
fault is intended to protect the capacitor bank from an overvoltage
condition especially if a 400V class drive is inadvertently placed in a
600V system.
• Verify the incoming line voltage.
11162

11362 C1 Line Loss
C2 Line Loss
C3 Line Loss Resettable
Fault Coast Y An AC line loss has occurred.
• Monitor the incoming AC line for low voltage or line power
interruption.

11363 C1 Fault Q Full
C2 Fault Q Full
C3 Fault Q Full Resettable
Fault Coast The fault queue is full. There are at least three other faults in the queue.
• Troubleshooting and clearing the existing faults will make room for
additional faults in the queue (if any).
