X X X X X X U1A Online 232 INVERTER SGCT WARNING
This warning occurs if Redn Dvc Inv option is selected in
HardwareOptions1 (P141). SGCT device in the inverter section
was detected to be faulted while the drive was running. The
drive detected that the diagnostic feedback from this device did
not match the gating pattern.
• After isolating the drive from medium voltage, be sure that the
device, IGDPS power supply and the fiber-optic signals are not
damaged.
• Complete a resistance check per the instructions in the manual.
NOTE: SGCTs may not have completely shorted, and still could read
in the k range. Any devices with low suspect readings should be
changed.
• Check the LED status of the SGCT gate driver card for abnormal
readings.
• Complete a Gating Test mode check on the devices.
• Verify the associated 20V power supply is powered and active.
• Verify all the power connections to the SGCT firing card are seated
properly.
• For nuisance faults, contact the factory about extending the
diagnostic delay.
NOTE: For Redundant devices, there will be no change in the drive
operation. For N-1 drives, the drive will attempt to run at a load/
speed combination that does not exceed the voltage rating of the
remaining devices.
