4-4 SB3000 Power Modules (Rittal)
4.3 Power Module Faults and Warnings
The PMI Processor continually runs diagnostics which check for errors that may affect
system operation. Warnings are errors which indicate that the SB3000 Synchronous
Rectifier is not operating in an optimum manner. Warnings will not shut down the
SB3000. Faults are severe errors which will shut down the SB3000. See tables 4.3
and 4.4.
Refer to the SB3000 Synchronous Rectifier Configuration and Programming
instruction manual (S-3034) for more information about the Fault and Warning
registers.
