HELP
• The HELP key provides information on each key function. The help message generally gives
associated functions and ways of changing the use of each key. When the display shows the
main pressure display, the user can get help on any of the keys on the key-pad. To do this:
• Press the required key for information, then press HELP.
• Press CLEAR/QUIT to exit the help system.
ENTER
• Press ENTER to complete a numeric entry.
CLEAR/QUIT + ENTER (ABORT)
• When CLEAR/QUIT and ENTER are pressed simultaneously, the ADTS 505 restarts from the
power-up sequence.
• When these keys are pressed all output valves immediately close, isolating the aircraft
systems.
• The ABORT function should only be used as a last resort:
• When a restart is required after the system has shutdown displaying an error message.
• As an emergency measure.
• If the system is restarted by pressing ABORT , it vents to atmosphere during the power-up
sequence. The aircraft systems remain at the original pressures. At a later stage in the
power-up sequence, the aircraft system pressures are sampled and the Ps (static) and Pt
(pitot) channels reconnected with a small pressure loss.
