2.8.4 Diagnostic Codes
When a fault is detected, the monitor transfers the Output relay contacts to the fault condition and illuminates the front panel
DIAG FAIL LED. The channel LEDs will also begin to flash a binary representation of the diagnostic code. The diagnostic
code may be viewed on the Fault Codes screen or with RaeComM on the Real Time Status display.
