7.3 Display board diagnostics
After accessing the diagnostics system, the display board is checked for correct operation. All the LEDs
(and, if featured, the display) light in sequence.
When the various buttons are pressed, the corresponding LEDs light. The display shows a binary code
corresponding to the code of the button pressed and the buzzer sounds.
When the FABRICS or TEMPERATURE buttons are pressed, the corresponding LED lights for a moment
and the binary code is displayed. On completion of the test, the buzzer sounds and the system passes to the
previous or subsequent phase of the diagnostics cycle.
