DIAGNOSTICS
There are two diagnostic tools available. The first tool provides a
series of self-tests the controller automatically runs at start-up. The
DIAGNOSTICS
menu selection from the setup menu also provides
those self-tests plus an additional group of tests. The second tool is
the
STATUS
menu selection from the monitor menu. It provides spe-
cific error information through a display of status bytes.
If no security level was assigned to the setup function, a master pass-
word is required to enter the diagnostics screen. The tests on the first
and second diagnostic screen are for the main board and operator
interface board, respectively. These tests run automatically when the
diagnostics screen is entered. The third diagnostics screen contains I/
O and keyboard tests.
