SPECIAL DIAGNOSTICS
In addition to the self-check tests that are part of the power-up sequence,
the HS15
plus
plotter can perform other special diagnostics. The steps to
access these diagnostics and their functions are outlined below.
To access special diagnostics
1. Hold down the
RESET
key while turning the power switch on.
2. After the first beep, release the
RESET
key. The power-up self test
will complete normally. Then the lights over
RUN CONT
and
RUN
SINGLE
keys will alternate. These alternating lights mean that
RESET
was held at power-up and that a special diagnostic can now
be performed.
3. Access one of the special diagnostics described next by pressing the
slew key noted in the description.
Note: Only one special diagnostic can be accessed at each power-up
sequence. To access another diagnostic, turn the plotter power off
and then on again (as described above).
Diagnostic Options
The following diagnostics are available:
RS232 Loop Back

Press the up arrow key to access. Used to
check internal workings of the communications hardware. Beeps
indicate a communications error. (A loop back connector is needed
for this test; see your Gerber distributor.)

to check X, Y, Z axes in plot mode and to verify operation after
