At ground and zero the display shows safe at ground for 5
seconds then the ADTS 505 system closes the output valves
to isolate the aircraft system and goes into a system datum
check routine (includes operation of the pump and control
valves) go to 3.7.8 for more details.
After completion of the system datum check routine the
display shows safe at ground and the message "Press Clear/
Quit to continue".
It is now safe to continue testing or to switch off and
disconnect the aircraft system.
When familiar with these procedures go to 3.5.4 to leak test
the ADTS 505.
