Self Test Routine
Self Test - Part 2
After the first part of the Self Test Routine, all LEDs turn
off and the LCDs become blank. This condition persists
for 2 to 5 seconds. During this second part, you should
again scan the panels and check that all LEDs go off and
LCDs are blank. DO NOT press any of the crosshead con-
trol switches, as a short circuit test occurs during this part.
When the Self Test Routine has been completed, the Main
Panel Display shows a four-digit test result, as described in
the Section "Self Test Result Display". All other LCDs
should be blank and LEDs should be off, except as de-
scribed in the operating procedures of Chapter 6.
Self Test Result - No Failures
The four-digit test result, which appears on the Main Panel
Display after the Self Test Routine, disappears after about
5 seconds if no board failures are detected. Normal system
operation can then begin, as described in Chapter 6. Also,
operation can begin more quickly, if desired, by pressing
ENTER on the keypad before the test result disappears.
The REJECT and S1 keys are active when the test result
is displayed, but would not normally be used at this
time. Pressing REJECT recycles the Self Test Routine,
and pressing S1 activates the Diagnostic Monitor which
should be used only by qualified maintenance personnel.
In the case of no failures, the test result is useful only in
determining what optional circuit boards are installed in
the console. This can be interpreted from the description
of the test result in Section "Self Test Result Display". If
this information is necessary, record the test result at this
time.
