Description
Recommended Action
50
R, I
AB/F
HW
Overcurrent
The long-duration
transistor is over current.
This may be caused by a
short circuit in the load.
Note: The limit is set by the
hardware.
Investigate the load for short
circuits.
51
R, I
W
Current Limit
The inverter’s (or rectifier’s)
current exceeds 110% of its
rating.
Reduce the load’s current to
maintain full protection.
52
I
W
Bypass
Current High
Bypass Current High.
No action required.
53
M
AB
System HW
Overcurrent
The load’s current exceeds
the rating of Inverter. There
may be short term transient
over currents. Note: The
limit set by the hardware.
Ensure that the load is
suitable.
54
M
AB
System
Current High
The load current is near the
limit. The limit is 160% of
Inverter rating. Note: The
limit is set by the software.
Reduce the load’s
current to
maintain full protection.
55
R, I
F
Sine Filter
Over Temp
The PTC (Positive
Temperature Coefficient
thermistor) in module sine
filter choke indicates
temperature is too high.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
56
R, I
AB
Heatsink Hot
The inverter’s (or rectifier’s)
heat sink is too hot.
Note: A sensor is mounted
on the heat sink.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
57
R, I
F
Heatsink
Over Temp
The inverter’s (or rectifier’s)
heat sink is too hot.
Note: A sensor is mounted
on the heat sink.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
58
R, I
AB
Enclosure
Hot
The inverter (or
rectifier’s)
enclosure’s internal
temperature is too hot
(near limit).
Note: The temperature is
monitored by a thermistor
in enclosure.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
59
R, I
F
Enclosure
Over Temp
The inverter (or rectifier’s)
enclosure’s internal
temperature is too hot
(over the limit).
Note: The temperature is
monitored by a thermistor
in enclosure.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
60
R, I
AB
Transistor
Case Hot
The inverter’s (or rectifier’s)
IGBT (Insulated Gate Bipolar
Transistor) case temp is too
hot (near limit).
Note: The temperature is
calculated using a thermal
model.
Ensure all module fans are
operating.
Ensure the ambient
temperature is not too high.
