I had replies from:
Thorsten.Biel@ks.sel.alcatel.de
"Bruce Rossiter" <AROSSITE@us.oracle.com>
"Michael Baumann" <baumann@proton.llumc.edu>

No one found a translation for the LED display, but everyone recommended
connection of a dumb terminal and setting the "diag" switch on the
system board. Doing so promptly showed me that the fuse on the SCSI
adaptor was blown. The blown fuse was caused by connection of an
old tape drive that had its internal SCSI connector improperly
aligned (i.e., it was one pin offset).
