X 2U1A OfflineOpen 372 6P or 18P SCR RECTIFIER FAULT
(Offline Open-Circuit)
For SCR rectifiers, this fault will occur after the initial contact closure,
or during the diagnostic sequence after a start command. After the
short-circuit test described below, the drive fires each device, and
verifies that the feedback from that device went low. If the feedback
does not go low, the drive assumes the SCR must be open-circuited.
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 cable integrity from FOI board transmitter to SCRGD board receiver.
Replace all faulty components.
