Diagnostic Options
Diagnostic Options
Stop Option S/LSI ALI ALS/B/OM
5 STOP ON FIRST ERROR
This is the default option. The diagnostic request is executed. On
detection of the first error, testing stops and the error information is dis-
played.
If you type G (go), the execution resumes from the error, until a second
error is detected. The error information is displayed and the request
stops again.
LS LOOP ON FIRST ERROR WITH STOP
The diagnostic request is executed until the first error is detected. The
DCF then displays this error and stops. Entering G (go) causes the DCF to
loop on the error, and to stop and display when the same error is
detected again.
The loop is maintained on this error display whether the error which initi-
ated the loop remains. If a new error appears inside the loop, it is dis-
played as N ERe (new ERC). However, the loop is maintained on the first
error detected.
At each display stop, you may enter one of the commands of the menu (A,
G, C, R, or M).
AL AUTOMATIC LOOP ON ERROR
The diagnostic request is executed until the first error is detected. The
DCF displays this error and starts looping on the error automatically. The
loop is maintained on this error whether the error which initiated the loop
remains. If a new error appears inside the loop, it is displayed as N ERC
(new ERC) and N RAC (new RAC), but ·even then, the loop is maintained
on the first error detected.
To regain control once the loop has been initiated, you must press the
BREAK (ATTN) key (refer to the procedure in Figure 3-5 on page 3-8).
ALS AUTOMATIC LOOP ON ERROR WITH NEW ERROR STOP
The diagnostic request is executed until the first error is detected. The
DCF displays this error and begins to loop on the error automatically. The
loop is maintained on this error display, whether the error that initiated
the loop remains. If a new error appears inside the loop, it is displayed
as N ERe (new ERC) and N RAe (new RAC); the DCF stops on this
display.
You may now enter any command of the 'execution modify' menu (refer to
Figure 3-4 on page 3-7).
If no N ERC or N RAC occurs, the only way to regain control is to press
the BREAK (ATTN) key. (refer to the procedure in Figure 3-5 on page 3-8)
B BYPASS ERROR STOPS
The diagnostic request is executed until an error is detected. On
detection of the error, the DCF displays the error information; testing then
resumes automatically until another error is detected or until the request
is complete. The only way to regain control before the end of the request
