SELF TEST ERROR CODES
To interrogate the machine to determine the
nature of a diagnostic failure, the operator must
use the buttons on the instrument panel. We have
associated a group of error codes to each button
on the instrument panel. If the operator presses
the button assigned to a group that has sensed an
error, the controller will display the error code
using the brush pressure LED’s. If the operator
presses a button assigned to a group that has not
sensed an error, the controller will display no error
code on the brush pressure LED’s.
The error code assignments are as follows:
ACTUATOR GROUP,
SQUEEGEE BUTTON PRESSED
