Troubleshooting and Error Codes
Chapter 1
7
Overload
When input current exceeds 125% for
60 seconds or 150% for 30 seconds.
The overload is a linear type in
counting up.
Reduce the current consumption of the
AFE or increase parameter 133 [Cnvrtr OL
Factor].
8
HeatsinkOvrTp
The power structure heatsink
temperature has exceeded the
maximum allowable value.
85 °C (185 °F) = Alarm
90 °C (194 °F) = Fault
Verify that the maximum ambient
temperature has not been exceeded.
Check the fans (including the ASIC board
on the converter).
Check for an excess load.
Verify that the airflow plate is installed.
See
.
9
IGBT OverTemp
The output transistors have exceeded
their maximum operating temperature
due to an excessive load.
Verify that the maximum ambient
temperature has not been exceeded.
Check the fans.
Check for an excess load.
10
System Fault
A hardware problem exists in the
power structure.
Reset the fault and restart.
Verify the fiber-optic connections.
Verify ASIC board jumper connections
from X9 to X15 (see
Contact technical support.
If the problem persists, replace or repair
the power structure.
12
AC OverCurr
The AC line current has exceeded the
hardware current limit.
Check for an excessive load or other causes
of excess current.
13
Ground Fault
A current path to earth ground exists
that is greater than the parameter 082
[Ground I Lvl] value. The current must
appear for 800 milliseconds before the
unit will fault.
Use a digital voltmeter to check for low
impedance to ground, and verify the bus
cables/bars between the:
Disconnect and AC input lines
Power structure and LCL filter
For AFE in IP20 enclosure:
• Q0 input breaker and K1 input
contactor, which includes the
precharge disconnect
• LCL filter and K1 input cont.
For AFE in IP21 enclosure:
• Q1 (MCCB) and Q0 disconnect switch,
which includes the precharge
disconnect
• LCL filter and Q1 (MCCB)
14
Power Structure
Fault
A hardware problem exists in the
power structure.
Cycle the power.
Contact technical support.
If the problem persists, replace the
converter unit.
17
LineSync Fail
One input of the known phase rotation
is missing.
Check all user-supplied fuses.
Check the AC input line voltage.
21
Phase Loss
There are zero current in one of the
three phases.
Check supply voltage, fuses, and cable.
29
Anlg In Loss
An analog input is configured to fault
on a signal loss. A signal loss has
occurred. Configure this fault with
parameter 203 or 206 [Anlg In x Loss].
Verify parameter 203 or 206 [Anlg In x
Loss] setting. Verify that input signal
levels are greater than or equal to 1.5V or
3 mA.
Check for broken/loose connections at the
inputs.
30
MicroWatchdog
A microprocessor watchdog timeout
has occurred.
Cycle the power.
Replace the control board. See
.
31
IGBT Temp Hw
The AFE input current has exceeded
the 1 minute overload rating.
Check for an excess load.
