Special Diagnostics
In addition to the self-check tests that are part of the power-up sequence, the
GSx
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 during power-up.
2
When a steady tone sounds, release the RESET key. There will be two
beeps followed by three beeps as the self-check tests are completed.
Then the lights above the 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:
♦
RS-232 Loop Back
– Press the up arrow key to access. Used to check
internal workings of the communications hardware. Beeps indicate a
communications error. (A special loop-back test connector is needed for this
test. See your Gerber distributor.)
♦

check X, Y, Z axes in plot mode and to verify operation after adjustments are
made.
