LCD Diagnostic Codes
To change the LCD display from cycle count to diagnostic
mode, press the “diag” button on the control board (see
illustration at right). When
fi
nished, press button again to
return to cycle count mode. When all of the harnesses
are correctly connected to the control board, the values
shown in the chart below will display when the correspond-
ing action is taken. “1” will appear to the right of the switch
or sensor name on the LCD module when activated as
shown. If any other value appears on the LCD screen
during the speci
fi
c diagnostic procedure, verify that the
correct harness is properly connected to both the control
board and the associated lift harness. Repeat the harness
diagnostic procedure. If an incorrect value is still present
after checking the harness and connections, contact The
Braun Corporation Product Support Department.
