X X 2U1A OfflineShrt 322 6P SCR RECTIFIER WARNING
This warning occurs if Redn Dvc Rec option is selected in
HardwareOptions1 (P141) and is valid only for 6P SCR drives.
This SCR device was detected to be short circuited after the
input contactor was closed or following a start command.
• After isolating the drive from medium voltage, be sure that the
device, snubber circuit, sharing resistor and the fiber-optic signal
are not damaged.
• Complete a resistance check on the rectifier, including the gate-
cathode resistance, the snubber and sharing resistors.
• Complete a firing check on the rectifier.
• Verify the snubber circuitry, and the sharing resistors.
• Verify fiber-optic integrity from SCRGD board transmitter to FOI
board receiver.
• Replace all faulty components.
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.
