X X X X X X 2U1A Offline 286 PWM RECTIFIER SGCT WARNING
This warning occurs if Redn Dvc Rec option is selected in
HardwareOptions1 (P141). This SGCT device on the rectifier side
was detected to be faulted after the input contactor was closed
or following a start command or following a drive reset.
• 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.
NOTE: There is only the Redundant option available on the Rectifier,
and only on 6P drives (SCR or PWM). You cannot have N-1 operation
on the rectifier since we cannot control the line voltage.
